Hydrogeomorphology has been defined as “an interdisciplinary science that focuses on the interaction and linkage of hydrologic processes with landforms or earth materials and the interaction of geomorphic processes with surface and subsurface water in temporal and spatial dimensions.” The term 'hydro- geomorphology’ designates the study of landforms caused by the action of water. By this definition hydro-geomorphology is inseparable part of geomorphology moreover fluvial geomorphology, because water is one of the most important agents in forming and shaping of landforms. From the groundwater point of view integration of geological, structural and hydrological data with hydro-geomorphologic data is very much useful in finding out the groundwater potential zones with fruitful results.

Desert geomorphology or the geomorphology of arid and semi- arid lands shares many landsforms and processes with more humid regions. One distinctive feature is the sparse or lacking vegetation cover, which influences fluvial and slope processes, related to wind and salt activity.Goudie 2013, p. 1 Early work on desert geomorphology was done by Western explorers of the colonies of their respective countries in Africa (French West Africa, German South West Africa, Western Egypt), in frontier regions of their own countries (American West, Australian Outback) or in the deserts of foreign countries such as the Ottoman Empire, the Russian Empire and China.
Her research determined which characteristics of riverscapes are valued by certain demographics of the population through a ratings system that determined factors of beauty. Morisawa furthered her research on watersheds and geomorphology, publishing the article Quantitative Geomorphology of Some Watersheds in the Appalachian Plateau. Her research included looking at the geologic structure of the watershed basins in the Appalachian Plateau, and how other interactions affect the streamflow and geomorphology of the basins. The stratigraphy or specifically sequence stratigraphy of basins include anticlines that have been eroded over time and the outer edges of the basin defined with steep scarps.

In so doing, pedologists develop systems of soil classification, soil maps, and theories for characterizing temporal and spatial interrelations among soils . There are a few noteworthy sub- disciplines of pedology; namely pedometrics and soil geomorphology. Pedometrics focuses on the development of techniques for quantitative characterization of soils, especially for the purposes of mapping soil properties whereas soil geomorphology studies the interrelationships between geomorphic processes and soil formation.
Many groundbreaking and widely cited early geomorphology studies appeared in the Bulletin of the Geological Society of America, and received only few citations prior to 2000 (they are examples of "sleeping beauties") when a marked increase in quantitative geomorphology research occurred. Quantitative geomorphology can involve fluid dynamics and solid mechanics, geomorphometry, laboratory studies, field measurements, theoretical work, and full landscape evolution modeling. These approaches are used to understand weathering and the formation of soils, sediment transport, landscape change, and the interactions between climate, tectonics, erosion, and deposition. In Sweden Filip Hjulström's doctoral thesis, "The River Fyris" (1935), contained one of the first quantitative studies of geomorphological processes ever published.

Terrain measurement techniques are vital to quantitatively describe the form of the Earth's surface, and include differential GPS, remotely sensed digital terrain models and laser scanning, to quantify, study, and to generate illustrations and maps.e.g., DTM intro page, Hunter College Department of Geography, New York. Practical applications of geomorphology include hazard assessment (such as landslide prediction and mitigation), river control and stream restoration, and coastal protection. Planetary geomorphology studies landforms on other terrestrial planets such as Mars.
If the tropics is defined as the area between 35° N and 35° S, then about 60% of Earth's surface lies within this zone.Gupta 2011, pp. 3–4 During most of the 20th century tropical geomorphology was neglected due to a bias towards temperate climates, and when dealt with it was highlighted as "exotic". Tropical geomorphology do mainly differ from other areas in the intensities and rates at which surface processes operate, and not by the type of processes.

Dictionary of Geological Terms: Third Edition, p. 125 (1984) American Geological Institute Each stage has distinct landforms and other properties associated with them, which can occur along the length of a river's upper, middle, and lower course. Though the cycle of erosion was a crucial early contribution to the development of geomorphology, many of Davis' theories regarding landscape evolution, sometimes termed 'Davisian geomorphology', were heavily criticized by later geomorphologists.
Because ocean basins are the ultimate sinks for a large fraction of terrestrial sediments, depositional processes and their related forms (e.g., sediment fans, deltas) are particularly important as elements of marine geomorphology.

An example is the wearing away of rock on a river or seabed by the impact or grinding action of particles moving with the water.Huggett, Richard John (2007). Fundamentals of Geomorphology. Routledge, London.
Despite considerable criticism the cycle of erosion model has remained part of the science of geomorphology. The model or theory has never been proved wrong, but neither has it been proven. The inherent difficulties of the model have instead made geomorphological research to advance along other lines. In contrast to its disputed status in geomorphology, the cycle of erosion model is a common approach used to establish denudation chronologies, and is thus an important concept in the science of historical geology.

Geomorphology is the scientific study of the origin and evolution of topographic and bathymetric features created by physical or chemical processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphology is practiced within physical geography, geology, geodesy, engineering geology, archaeology and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field.
Like Wooldridge, Linton was a fieldworker whose approach has been superseded by the study of processes and quantitative analysis. Their major work on the development of south-east England has been shown to be based on too simplistic a view of tectonic history. It nonetheless remains as an enduring monument to one of the most distinctive phases of British geomorphology. The David Linton Award of the British Society for Geomorphology (which incorporates the British Geomorphological Research Group) is given to a geomorphologist who has made a leading contribution to the discipline over a sustained period.
Sundborg's filosofie licentiat thesis had as subject the city climate of Uppsala. The thesis came to be internationally recognized with climatologist Helmut Landsberg praising it for containing one of the first theories on the climate of cities. Åke Sundborg was drawn to the charismatic Filip Hjulström who influenced him to shift his field of study and pursue Ph.D. studies on fluvial geomorphology under his tutelage. Sundborg's 1956 Ph.D. thesis explored the link between geomorphology and hydrology in the meanders of the lower course of Klarälven in his native Värmland.

Trawling gear produces acute impacts on biota and the physical substratum of the seafloor by disrupting the sediment column structure, overturning boulders, resuspending sediments and imprinting deep scars on muddy bottoms. Also, the repetitive passage of trawling gear over the same areas creates long-lasting, cumulative impacts that modify the cohesiveness and texture of sediments. It can be asserted nowadays that due to its recurrence, mobility and wide geographical extent, industrial trawling has become a major force driving seafloor change and affecting not only its physical integrity on short spatial scales but also imprinting measurable modifications to the geomorphology of entire continental margins.Oberle et al. (2018), “Submarine Geomorphology: Bottom Trawling and other Fishing Activities”, Book: Submarine Geomorphology Chapter 25, Springer, doi: 10.1007/978-3-319-57852 Bottom fishing has operated for over a century on heavily fished grounds such as the North Sea and Grand Banks.

The Geological Survey of Estonia completed mapping of Paleozoic bedrock and Quaternary sediments by 1975. Additional maps of hydrogeology, geomorphology, engineering geology and even geoecology have been completed since then. Up until 1990, all geologic publications were written in Russian.
Morphological mapping schemes, emphasising slope, were the subject for discussion at early meetings of the BGRG. Time-consuming to undertake, such schemes produced information about form but not about the processes or the origin of land forms. These schemes evolved in the 1970s to produce geomorphological maps of the UK. Several articles published in the Geographical Magazine in 1975 and 1976 explained the landform maps produced for all parts of Britain. In 1985 the BGRG celebrated its first twenty five years by hosting the first International Geomorphology Conference in Manchester which led to the formation of the International Association of Geomorphology.
Bernard Smith supervised the launch of many geomorphological careers with his thoughtful PhD supervision influenced many of the undergraduate students who came into contact with him. He was an inspiring teacher who believed that it was essential for the future of geomorphology that all students and practitioners should have a thorough understanding of the history and development of the subject. During his time on the British Society for Geomorphology (BSG) Executive Committee he did much to further the support for postgraduates. For many years he was an organiser and facilitator of the 'Windsor Workshop' for new research students run by the BSG.
There is a considerable overlap between geomorphology and other fields. Deposition of material is extremely important in sedimentology. Weathering is the chemical and physical disruption of earth materials in place on exposure to atmospheric or near surface agents, and is typically studied by soil scientists and environmental chemists, but is an essential component of geomorphology because it is what provides the material that can be moved in the first place. Civil and environmental engineers are concerned with erosion and sediment transport, especially related to canals, slope stability (and natural hazards), water quality, coastal environmental management, transport of contaminants, and stream restoration.
This was the first study of the karst regions of China by a western geomorphologist. Marjorie was acknowledged not only as an international expert on karst geomorphology but also as a generous and enthusiastic mentor for generations of undergraduate and graduate students. For much of her career, Marjorie was one of only a small group of female physical geographers in Britain who fought hard and successfully to establish their international scientific reputation. After retirement, Marjorie Sweeting continued her research in China which culminated in ‘Karst in China: its Geomorphology and Environment’, the manuscript being published in 1995, shortly after her death.

Dury's model is an extension of the Bradshaw model which shows how river characteristics will change from the upper course to the lower course of a river. Dury used a line graph and a logarithmic scale, plotting the discharge along the x-axis and the other stream variables along the y-axis. Other 'stream variables' included depth, width, velocity, slope (gradient) and friction (Manning formula). Dury's work on quantitative fluvial geomorphology led to a temporary period with the United States Geological Survey in 1960–61 and to co-authorship of the influential study Fluvial Processes in Geomorphology (with Luna B. Leopold, M. Gordon Wolman, and John Miller, 1964).
Planetary science frequently makes use of the method of comparison to give a greater understanding of the object of study. This can involve comparing the dense atmospheres of Earth and Saturn's moon Titan, the evolution of outer Solar System objects at different distances from the Sun, or the geomorphology of the surfaces of the terrestrial planets, to give only a few examples. The main comparison that can be made is to features on the Earth, as it is much more accessible and allows a much greater range of measurements to be made. Earth analogue studies are particularly common in planetary geology, geomorphology, and also in atmospheric science.
At the University of Wisconsin (1960-66), Butzer regularly offered a course on Pleistocene environments, including what is now called geoarchaeology, in addition to introductory physical geography, and graduate seminars in climatology and coastal geomorphology. At the University of Chicago (1966-84), he taught advanced courses in physical geography, applied geomorphology, and environmental archaeology, as well as graduate seminars in settlement archaeology and geography. At the ETH-Zurich (1981-82), he introduced a new program in human geography, which continued to be implemented after his departure. At the University of Texas (since 1984), he offered graduate courses in geoarchaeology and environmental history; cultural ecology; historical geography; and landscape, society, and meaning.

Cuspate forelands can form both along coastlines and along lakeshores. Those formed along coastlines can be in the lee of an offshore island, along a coastline that has no islands in the vicinity, or at a stream mouth where disposition occurs.Bird, E., 2008 Coastal geomorphology: an introduction. 2nd ed.
Cerro Autana as other table-top mountains in the region is the remains of a large sandstone plateau that once covered the granite basement complex between the north border of the Amazon Basin and the Orinoco, between the Atlantic coast and the Rio Negro. The table-mountain topography is formed as water percolates along joints and bedding planes, the siliceous cement dissolves, quartzite disaggregates and large blocks collapse which accumulate in the foot of the scarps. The percolating water forms large and intricate cave systems, which frequently emerge in the scarp zone as high waterfalls.Briceño, Henry O. and Schubert, Carlos (1990), 'Geomorphology of the Gran Sabana, Guayana Shield, southeastern Venezuela', Geomorphology, 3 (2), 125-41.
In the winter season, he focused his geological field work in the Mojave Desert of California, with emphasis on the geomorphology of Cima Dome, and the sliding stones on the Racetrack Playa in northern Death Valley. Robert Phillip Sharp was an expert on the physics of blown sand and the formation of sand dunes in the Mojave Desert and the Coachella Valley. He was awarded the Kirk Bryan Award by the Geological Society of America for his scholarly publications on the geomorphology of sand dunes in desert terrain. Professor Sharp loved weekend field trips, and so he authored a number of field books in geology of southern California, published by Mountain Press.
Due to the geology in the area, the geomorphology of the watershed is unique. The river begins at Diablo range in the east. In the south, from the Gabilan mountains flows another tributary northward. From the north, tributaries flow from the Santa Cruz mountains southward to meet with the Pajaro.

Its content ranges from planetary evolution to computer modeling of fossil development, making it relevant to geologists as well as other researchers working in the Earth or planetary sciences.
The hydrological balance is critical for the initiation of peat. The hydrological balance can simply be defined as the difference between the incoming and outgoing amount of water (e.g. precipitation minus evapotranspiration and minus runoff). Usually it is considered that factors such as climate, geomorphology, geology and soils control this balance.

A physiographic province is a geographic region with a characteristic geomorphology, and often specific subsurface rock type or structural elements. The continents are subdivided into various physiographic provinces, each having a specific character, relief, and environment which contributes to its uniqueness. The physiographic provinces are then subdivided into smaller physiographic sections.
Hamadas are produced by the wind removing the fine products of weathering: an aeolian process known as deflation. The finer-grained products are taken away in suspension, while the sand is removed through saltation and surface creep, leaving behind a landscape of gravel, boulders and bare rock.B.W. Sparks. Geomorphology, 2nd ed.

Early in his career, his interest in the application of mathematics to his fields of study, especially that of planetology, led him to the observatory of Paris-Meudon. He suggested and started applying geological science to planetary bodies other than the Earth as early as 1948, studying and publishing on the geomorphology and physics of the Moon, Mars, and other planets."Memorial to André Cailleux", Marc Deschamps""André Cailleux et la Planétologie", Audoin Dolfus" He conducted scientific conferences in 20 foreign countries, taught at the Sorbonne, Université Laval in Quebec, and the California Institute of Technology, and published 390 scientific works, on geomorphology, oceanography, hydrology, glaciology, petrography, mineralogy, geography, paleontology, planetary geology, and history. Cailleux was a Christian and proponent of theistic evolution.
During the early 1900s, the study of regional-scale geomorphology was termed "physiography". Physiography later was considered to be a contraction of "physical" and "geography", and therefore synonymous with physical geography, and the concept became embroiled in controversy surrounding the appropriate concerns of that discipline. Some geomorphologists held to a geological basis for physiography and emphasized a concept of physiographic regions while a conflicting trend among geographers was to equate physiography with "pure morphology", separated from its geological heritage. In the period following World War II, the emergence of process, climatic, and quantitative studies led to a preference by many earth scientists for the term "geomorphology" in order to suggest an analytical approach to landscapes rather than a descriptive one.

As soon as possible, Caltech's Division Chairman Ian Campbell arranged for Sharp to return home to Caltech as a full professor in 1947. Sharp remained at Caltech for the next half-century, and was quickly promoted to the Chairman of the Division of Geological Sciences, later renamed to the Division of Geological and Planetary Sciences. While at Caltech, Sharp mentored dozens of doctoral students in field geomorphology; these are now working at the United States Geological Survey facility in Menlo Park, California and in leading geology departments throughout North America. Sharp became a published expert on the glacial geomorphology of the Sierra Nevada range, the Trinity Alps of northwestern California, the Olympic Peninsula of Washington, and Mount Saint Elias in the Fairweather Range of Alaska.
Geologic mapping and interpretation of geomorphology are typically completed in consultation with a geologist or engineering geologist. Geophysical exploration is also sometimes used. Geophysical techniques used for subsurface exploration include measurement of seismic waves (pressure, shear, and Rayleigh waves), surface-wave methods and/or downhole methods, and electromagnetic surveys (magnetometer, resistivity, and ground-penetrating radar).

Seeps are usually not of sufficient volume to be flowing beyond their above-ground location. They are part of the limnology-geomorphology system. Like a higher volume spring, the water is only from underground sources. Seeps mostly occur in lower elevation areas because water runs downhill, but can happen higher up if the groundwater present is abundant enough.
Lichenometry is a technique used to determine the age of exposed rock surfaces based on the size of lichen thalli. Introduced by Beschel in the 1950s, the technique has found many applications. it is used in archaeology, palaeontology, and geomorphology. It uses the presumed regular but slow rate of lichen growth to determine the age of exposed rock.
The carvers attempted to establish four bays as well as with a recess. The pillars are rounded (which is uncommon) and expand at either end, supporting arches that appear as triangles. Women are not allowed to do the ascent, nor to visit monastery or church. Independently from the difficult access to the monastery, the surrounding sandstone geomorphology is unique.
In contrast to its disputed status in geomorphology, the cycle of erosion model is a common approach used to establish denudation chronologies, and is thus an important concept in the science of historical geology. While acknowledging its shortcomings, modern geomorphologists Andrew Goudie and Karna Lidmar- Bergström have praised it for its elegance and pedagogical value respectively.
Grafton Notch reflects the glaciation processes carved by the Laurentide Ice sheet during the Wisconsin Glaciation episode. Notable geomorphology of the park includes U-shaped valleys, gorges, and esker. Erosional processes expose the unique bedrock composed of Devonian granite with pegmatite intrusions. Poorly sorted diamicton and stratified gravel pits indicate glacial and glacio-fluvial depositional processes at work.
During most of the 20th century three models of hillslope evolution were widely diffused: slope decline, slope replacement and parallel slope retreat. Until the 1950s models of hillslope form evolution were "central" in geomorphology. The modern understanding is that the evolution of slopes is much more complex than the classical models of decline, replacement and retreat imply.

By profession he was a geographer conducting studies in physical geography and geomorphology and working as a school teacher of geography as well as a university teacher.
Currently, she is an associate professor at the University of British Columbia's Vancouver campus in the department of geography. Koppes studies glaciers and climatology. Through various methods, her and her team are able to quantify the effects of climate change on landscapes and people. Her research is interdisciplinary; bringing together geomorphology, glaciology, climate, and human adaptation and resilience.
Alcántara-Ayala was born in Mexico City. She studied geography at National Autonomous University of Mexico and earned her bachelor's degree in 1993. Based on her performance during her undergraduate studies, she was awarded the Gabino Barreda medal. She was a graduate student at King's College London, where she worked on geomorphology and was awarded a PhD in 1997.
Terms such as "inverted valley" or "inverted channel" are used to describe such features.Pain, C.F., and C.D. Ollier, 1995, Inversion of relief - a component of landscape evolution. Geomorphology. 12(2):151-165. Inverted relief has been observed on the surfaces of other planets as well as on Earth. For example, well-documented inverted topographies have been discovered on Mars.
This is an intricate and very old method in Shilpa Shastra, by which the temple's direction and the auspicious moment for beginning the sacred construction is determined. Like the present day Geomorphology, Seismology, Topology etc., probably this is some ancient science which guides the architect to understand natural forces and build stable massive structures in Odisha.
Geomorphology, 129 (3-4): 238-251. This river had its greatest discharges and width in that period. The magnitude of floods in this river has however been decreased in recent years due to interventions in the catchment. On steep slopes, exclosures have been established; the dense vegetation largely contributes to enhanced infiltration, less flooding and better baseflow.
Folding in the South Stack Formation can be seen in the rocks of the mainland's sea cliffs. South Stack is an island known as a Sea Stack. It was formed by the wave erosion of sedimentary rocks that once connected the island to the mainland. Stacks are formed over time by wind and water, processes of coastal geomorphology.
This approach emphasized the empirical collection of data over the theoretical. The same approach was also used by Halford John Mackinder in 1887. However, the integration of the Geosphere, Atmosphere and Biosphere under physiography was soon over taken by Davisian geomorphology. Over the past two centuries the quantity of knowledge and the number of tools has exploded.
The Murzuq Desert, Idehan Murzuq, Idhan Murzuq, (also Murzaq, Murzuk, Marzuq and Murzak), is an erg in southwestern Libya with a surface of approximately 58,000 km2.Desert Geomorphology, p. 403 It is named after the town of Murzuk in the Fezzan. Like the Idehan Ubari further north, the Idehan Murzuq is part of the greater Sahara Desert region.

Geomorphology, 9(1), 33-45. Glaciated terrain is not the only site of hanging streams and valleys. Hanging valleys are also simply the product of varying rates of erosion of the main valley and the tributary valleys. The varying rates of erosion are associated with the composition of the adjacent rocks in the different valley locations.
Diagram showing the Strahler Stream OrderArthur Newell Strahler (February 20, 1918 – December 6, 2002) was a geoscience professor at Columbia University who in 1952 developed the Strahler Stream Order system for classifying streams according to the power of their tributaries. Strahler was largely responsible for the shift from qualitative to quantitative geomorphology during the mid 20th century.
Roland Paskoff (20 March 1933 – 14 September 2005) was a French geologist expert in coastal geomorphology including Holocene tectonics and sea level change. While he was active studying the coast of the countries where he held university positions—that is Chile, France and Tunisia— he also conducted studies in Bahrain, Malta, the Seychelles and the Mascarene Islands.

By conducting training courses Gobabeb aims to improve the public awareness and knowledge of dry land ecology and environmental issues. The station consists of permanent researchers, students, and interns, as well as short time visitors such as school and university groups, and tourists.
The elevation of marsh species is important; those species at lower elevations experience longer and more frequent tidal floods and therefore have the opportunity for more sediment deposition to occur.Cahoon, D. R., White, D. A. and Lynch, J. C. (2011). "Sediment infilling and wetland formation dynamics in an active crevasse splay of the Mississippi River delta". Geomorphology, 131: 57–68.
Referring to Stone (1960), settlement geography is With respect to Stone's definition, Jordan (1966) emphasizes that settlement geography not exclusively investigates the distributions, but even more the structures, processes and interactions between settlements and its environment (such as soil, geomorphology, economy or society), which produce them.Jordan, T.G. 1966: On the nature of settlement geography. In: The Professional Geographer, Vol. 18, No. 1, pp.
Mirusha Canyon The nature regional park of Mirusha covers throughout Klina, Malisheva and Rahovec municipalities on the eastern side of the Dukagjini plain, central Kosovo. The elevation typically ranges from to above sea level. The geodiversity of the Mirusha river basin represents important heritage components linked to geology, geomorphology and hydrology, important for science, education as well asfor touristic use.
These may include fieldwork and field data collection, the interpretation of remotely sensed data, geochemical analyses, and the numerical modelling of the physics of landscapes. Geomorphologists may rely on geochronology, using dating methods to measure the rate of changes to the surface.Summerfield, M.A., 1991, Global Geomorphology, Pearson Education Ltd, 537 p. .Dunai, T.J., 2010, Cosmogenic Nucleides, Cambridge University Press, 187 p. .
More recently concerns over global warming have led to a renewed interest in the field. Despite considerable criticism, the cycle of erosion model has remained part of the science of geomorphology. The model or theory has never been proved wrong, but neither has it been proven. The inherent difficulties of the model have instead made geomorphological research to advance along other lines.
He has also been Chair of the British Society for Geomorphology. He is the recipient of a number of honours and awards for his research and teaching including the Cuthbert Peek Award from the Royal Geographical Society, Charles Lyell Award from the British Association for the Advancement of Science and the Jan De Ploey Prize from the Katholieke Universiteit Leuven.
1911 Encyclopædia Britannica. Because the river is fed by melting snow from the mountains, it only carries water during the summer and is dry the rest of the year. Prior to construction of the Tarim Desert Highway in 1995, the Hotan river bed provided the only transportation system across the Tarim Basin.The Southwest Taklimakan Desert from NASA's Geomorphology from Space .
He published 75 academic papers and books on glaciation, geomorphology in Europe, geomorphological hazards and a geographical study of Africa. He was a gifted organist and was elected fellow of the Royal College of Organists when only 18 years old. He married Davina Caroline Cherry in 1956 and they had three sons. After their divorce he married Christine Hamann in 1991.
Knickpoints are formed by the influence of tectonics, climate history, and/or lithology.Paul R. Bierman, David R. Montgomery. Key Concepts in Geomorphology, Freeman, 2013 For example, uplift along a fault over which a river is flowing will often result in an unusually steep reach along a channel, known as a knickzone. Glaciation resulting in a hanging valley are often prime spots for knickpoints.
An important notion in the evaluation of analogue sites is that of "fidelity", which describes the resemblance of the analogue to its extraterrestrial correspondent. Fidelity is used in comparative planetary science to express the analogy of a terrestrial site to a target extraterrestrial surface. This classification is possible based on various criteria such as geomorphology, geochemistry, exobiology or exploration conditions.
The River Holford is located in the east Quantock Hills Area of Outstanding Natural Beauty in Somerset England. It is approximately long. Its source is at Lady's Fountain Spring, Frog Combe which is near Halsway and above sea level before flowing past Holford towards its mouth at Kilve. The river is used as an outdoor classroom for students of Fluvial Geomorphology.
Yizhar's early work was influenced by Uri Nissan Gnessin. His knowledge of Israeli geology, geomorphology, climate, and flora is evident in his landscape descriptions and his emphasis on the relationship between person and place. Yizhar's use of language is unique. With his long sentences and combination of literary Hebrew and street jargon, he draws the reader into his heroes' stream of consciousness.
Independently from the difficult access to the monastery, the surrounding sandstone geomorphology is unique. The Amani’el church in May Baha () has also been carved in Adigrat Sandstone. Behind a pronaos (1960s), the rock church has cruciform columns, flat beams and a flat ceiling, a single arch, and a flat rear wall without apse. Windows give light to the church itself.
There are numerous ancient archaeological sites in the range that display the stages of cultural evolution from the early Paleolithic Age (1 million BP) to the Neolithic Age (6500 BP).Paleolithic sites and geomorphology of Karatau mountain range - UNESCO World Heritage Centre This site was added to the UNESCO World Heritage Tentative List on September 24, 1998 in the Cultural category.
Marshall Wilkinson (Macquarie) also joined as visiting faculty in physical geography and geomorphology in 2006 and promoted to tenure-track in 2007 (he left the department in 2010). Jeff Levy (BA Kentucky) was also hired as department GIS analyst in 2006, joining Gilbreath in the cartography lab. Dick Ulack retired from the department in 2007 (he died in April 2011).
He contributed articles to the Geological Magazine, the Quarterly Journal of the Geological Society of London, and the Proceedings of the Somersetshire Archaeological and Natural History Society, and several other learned journals. He was awarded the Murchison Medal in 1914. The Ussher Society, named in his honour, was founded in 1962 to promote the study of geology and geomorphology in southwest England.
Electromechanical disintegration is a process in geomorphology in which lightning interacts in erosion and weathering. Karfunkel, 2001 (see: References). An excellent example of this phenomenon is fracturing in the quartz formations of the Espinaςo mountains of Brazil. For many years, itinerant miners in these mountains have reported the appearance of broken boulders and fissures along the ground after lightning storms.
A walrus (Odobenus rosmarus) in a pod on Wahlberøya in Hinlopenstrait, Svalbard. Note the sediment on its left tusk. Walruses, salmon, and pocket gophers are examples of large bioturbators.Humphreys, G. S., and Mitchell, P. B., 1983, A preliminary assessment of the role of bioturbation and rainwash on sandstone hillslopes in the Sydney Basin, in Australian and New Zealand Geomorphology Group, p. 66-80.
In 1891, geologist Nathaniel Shaler expanded Darwin's concept to include soil disruption by ants and trees. The term "bioturbation" was later coined by Rudolf Richter in 1952 to describe structures in sediment caused by living organisms. Since the 1980s, the term "bioturbation" has been widely used in soil and geomorphology literature to describe the reworking of soil and sediment by plants and animals.
Primarily, these are: scenic or landscape value; biodiversity value (species and habitats); geodiversity value (relating to geology and geomorphology); and cultural or historic value. Several types of protected areas are focused on more than one of these areas. Besides protected areas, a number of individual features are protected through other designations, such as tree preservation orders, listed buildings, and protected shipwrecks.
Other geomorphologists turned away from the cycle of erosion to work instead on climatic or tectonic geomorphology. The model spread fast. In 1901 Hans Reusch was using it to explain the undulating plateau of southern Norway. Very much influenced by Davis Walter Wråk moved to study the relief of the northern Scandinavian Mountains, describing among other things the Borsu surface.
Geohazards are associated with geological activity, geotechnical features and environmental conditions. Shallow geohazards are those occurring at less than below the seafloor.Peuchen and Raap, 2007. Information on the potential risks associated with these phenomena is acquired through studies of the geomorphology, geological setting and tectonic framework in the area of interest, as well as with geophysical and geotechnical surveys of the seafloor.
This process creates a zig-zagging fluvial valley that "interlock" or "overlap" in a staggered manner. If the river valley is subsequently subject to glaciation, glacial erosion widens the V-shaped valley and removes the ends of the interlock spurs projecting into the valley. As a result, the ridges are truncated to form truncated spurs.Thornbury, W. D. (1954) Principles of Geomorphology.
The diary included a record of the topography, geomorphology, climate, animals, plants and products of the island. He recommended Naridong as an appropriate residential area, because the area is flat and large enough for 1,000 households. He suggested 14 possible ports along the sea coast. Lee told King Gojong that he believed that Usan Island was the ancient name of Ulleungdo.
The same unique ecology and geomorphology has let to a number of designations of SSSIs along the strait including Glannau Porthaethwy, the ivy - oak - ash woodland on the southern shore (Coedydd Afon Menai) and Lavan Sands (Welsh: Traeth Lafan). Much of the land on Anglesey at the eastern end of the strait is designated as an area of outstanding natural beauty.

He traveled to Western Europe, India, China, Japan, Ceylon, Senegal, Algeria, Tunisia, Morocco, Guinea, Brazil, Chile, Uruguay, United States, Mexico, New Zealand, Australia. Gerasimov also was known for his work in geomorphology, the study of the earth's surface relief.
Controls on modern tributary- junction alluvial fan occurrence and morphology: High Atlas Mountains, Morocco. Geomorphology, 248, 344-362. The presence of many dwarf lamellibranchs in the South of Azilal, the fine oblique stratifications, the floating plants and imprints of raindrops demonstrate that these two formations are of Aquatic origin, may be lagoonal, with temporary emersions. Several Fish fossils have also been found.
Mesohabitat types are defined by their hydromorphological units (HMUs), such as pools and rapids, geomorphology, land cover and other hydrological characteristics. Mesohabitats are mapped under multiple flow conditions at extensive sites along the river. Fish data is collected in randomly distributed mesohabitats where habitat surveys are also conducted. This allows modeling of available fish habitat at a range of flows.
Paulo Gomes Varella (2009) A CRATERA DE COLÔNIA (in Portuguese). The crater is drained towards the east by the Vargem Grande creek into the adjacent Billings Reservoir. The tentative identification as an impact crater is based mainly on geomorphology, faulting pattern, and on the exclusion of other possible formation mechanisms. In particular, there are no carbonate rocks that could produce to karstic sinkholes.
Almost for half a century Levan Maruashvili travelled a lot over his native land and studied its nature.

A floodplain or flood plain or flood-plain is an area of land adjacent to a stream or river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudie, A. S., 2004, Encyclopedia of Geomorphology, vol. 1. Routledge, New York. The soils usually consist of clays, silts, and sands deposited during floods.
Lying within a coastal plain, the St. Johns River passes through an area that was at one time barrier islands, coastal dunes, and estuary marshes. The Florida Peninsula was created primarily by forces and minerals from the ocean. It lies so low that minor fluctuations in sea levels can have a dramatic effect on its geomorphology. Florida was once part of the supercontinent Gondwana.
Mesozoic rocks from 251 to 66 million years ago are largely absent in Guinea-Bissau. In the west, there is an unconformity between Paleozoic sediments and Cenozoic marine sediments, which are cut by mafic dykes. In the past 2.5 million years of the Quaternary, Guinea-Bissau's surficial geology and geomorphology have changed considerably, with the formation of new terraces and duricrust, as well as frequent marine transgressions.
In 2000, 40 years of the BGRG were celebrated by returning to Sheffield. Of those 19 geomorphologists who, by their action, can be regarded as the founders of the BGRG, which now has an international membership of around 700, nine attended this 40th Anniversary Meeting. One of them, Tony Orme, presented the Frost Lecture. In 2006 the BGRG changed its name to British Society for Geomorphology (BSG).
Many species of fish, including orange roughy, blue ling, leafscale gulper shark and Portuguese dogfish are also found here. In 2014 the bank was declared a Nature Conservation Marine Protected Area (NCMPA). The designation covers , and is in place to protect the sponge aggregations, and the cenozoic marine geomorphology of the seabed. The feature originated about 70 million years ago, as a result of volcanic activity.

Glacial striation and the presence of chalk and flint erratics that originated from the bed of the North Sea demonstrate the influence of ice action on the geomorphology of the islands. Boulder clay is also abundant and moraines cover substantial areas.Brown, John Flett "Geology and Landscape" in Omand (2003) p. 10.
From there he exercised an enormous influence in the development of periglacial geomorphology. He led the Periglacial Commission of the International Geographical Union from 1952 to 1972. He established the journal Biuletyn Peryglacjalny in 1954 and served as its editor-in-chief until 1972. In addition to his role in the Periglacial Commission and Biuletyn Peryglacjalny he had extensive contacts among Eastern Bloc scientists.
Landscape evolution models are used primarily in the field of geomorphology. As they improve, they are beginning to be consulted by land managers to aid in decision making, most recently in the area of degraded landscapes. The earliest of these models were developed in the 1970s. In these models, water was run across a mesh, and cell elevations were changed in response to calculated erosion.
Walery Władysław Daniel Łoziński (1880–1944) was a Polish geographer and soil scientist known for introducing the concept of periglaciation into geomorphology in 1909. Łoziński extended the work of Swedish geologist Johan Gunnar Andersson who had written about periglacial phenomena in Bjørnøya and the Falkland Islands. The concept of "periglaciation" was the subject of an intensive discussion at the 1910 International Geological Congress held in Stockholm.
On his return to the UK (via Land Rover across the Sahara) he took up a lecturing position in the Geography Department of Queen's University Belfast in 1979. This provided the academic base for the rest of his career, being appointed Senior Lecturer, Reader and finally held the Chair in Tropical Geomorphology from 1998. He continued in post until illness necessitated early retirement in 2011.
Macmillan Higher Education, 2014. Aristotle speculated that due to sediment transport into the sea, eventually those seas would fill while the land lowered. He claimed that this would mean that land and water would eventually swap places, whereupon the process would begin again in an endless cycle. Another early theory of geomorphology was devised by the polymath Chinese scientist and statesman Shen Kuo (1031–1095).
Although geomorphometry started with ideas of Brisson (1808) and Gauss (1827), the field did not evolve much until the construction of the first DEM.Miller, C.L. and Laflamme, R.A. (1958): The Digital Terrain Model- Theory & Application. MIT Photogrammetry Laboratory Geomorphology has a long history as a concept and area of study, with geomorphometry being one of the oldest related disciplines.Schmidt, J. & Andrew, R. (2005) Multi-scale landform characterization.
As a postdoctoral fellow at Caltech, and as a collaborator on the Mars Science Laboratory Science Team, she participated in daily planning of the Mars rover activities and uses its image data combined with orbital data to investigate the stratigraphy, geology, and geomorphology of Mars. In June 2017, she was selected as a member of NASA Astronaut Group 22, and began her two-year training in August.
Larsen has been able to quantify and evaluate these systems using mathematical models that consider hydraulic transport on the scale of seconds to months and geomorphology and biology over the course of decades and centuries. Larsen has also published a picture book called "One Night in the Everglades" in conjunction with the Long Term ecological Research Network, an organization funded by the National Science Foundation.
Then he earned honors degree in Geography specializing in Geomorphology from King's College, Cambridge with government scholarship. He also spent some time in Scott Polar Research Institute, studying one of his favorite interests - mountains, snow & ice. Back in his country in early 1950s, he joined University before returning to army again. Lt Col Maurice Brown was also a Fellow of the Royal Geographical Society.
It has been speculated that the Takaka Terrane is equivalent to rocks in Tasmania, Australia and was separated from them with the opening of the Tasman Sea. The Arthur Marble has been chemically weathered by rain and groundwater due to its high calcium carbonate content forming a karst geomorphology. This has led to the formation of extensive cave systems like Harwood Hole and the Riuwaka Resurgence.

She has contributed many scholarly articles to academic journals, including Geomorphology, Journal of Geology, Ecological Applications, Water Resources Bulletin, and Geological Society of America Bulletin. She has served as Associate Editor for Journal of Hydrology, Geological Society of America Bulletin, and Water Research.
The depth–slope product is used to calculate the shear stress at the bed of an open channel containing fluid that is undergoing steady, uniform flow. It is widely used in river engineering, stream restoration, sedimentology, and fluvial geomorphology. It is the product of the water depth and the mean bed slope, along with the acceleration due to gravity and density of the fluid.
Ironclad evidence of the impact hypothesis would have been removed during the ice ages, and unless more shock geomorphology is found the crater's origin cannot be certified beyond a reasonable doubt. Due to the spring fed nature of the lake, the water is exceptionally clear. According to residents of the lake, on calm days it is possible to see up to underwater with the naked eye.
Charles Cotton became an international authority on geomorphology using New Zealand active tectonics and variable climate to create universally applicably rules. His major works becoming standard text books in New Zealand and overseas. Charles Fleming established the Wanganui Basin as a classic site for studying past sea levels and climates.

The excavations included local high school students from Inukjuak. The trainees were exposed basic archeology techniques like collecting artifacts, recording data, basic excavation, dendrochronology, as well as geomorphology. Elders of the community shared their experiences traditional life in the area. Upon touring the site, the elders were amazed to discover how much wood was used by their ancestors in the construction of their houses.
The institute has scientific schools on population geography, exogenous geomorphology, landscape hydrology, and landscape planning. An achievement of the institute is mapping of nature, the economy and population in regions of Asian Russia and neighboring countries. Cartographic products produced include the National Atlas of Mongolia, the atlases of the Transbaikalia KATEK and Lake Hovsgol, the Ecological Atlas of the Irkutsk Region, and thematic maps.
They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density.A.J. Parsons and A.D. Abrahams, Editors (2009) Geomorphology of Desert Environments (2nd ed.) Springer Science & Business Media They can resemble malpaís, a terrain of volcanic rock. Canyons, ravines, gullies, buttes, mesas, hoodoos and other such geologic forms are common in badlands. They are often difficult to navigate by foot.
Chorley was born in Minehead, Somerset in an area known as the West Country, with roots in Exmoor and the Vale of Taunton Deane. He was a product of a local primary school and Minehead Grammar School. Later on, Chorley began studying Geomorphology as an undergraduate at the School of Geography at Oxford. He served with the Royal Engineers from 1946 to 1948 and made it Lieutenant.
An orographic map of Eastern Siberia from 1875 by Peter Kropotkin Orography (from the Greek όρος, hill, γραφία, to write) is the study of the topographic relief of mountains, and can more broadly include hills, and any part of a region's elevated terrain.Orography (from the American Meteorological Society website) Orography (also known as oreography, orology or oreology) falls within the broader discipline of geomorphology.

He subsequently was professor of physical geography, climatology and cartography between 1970 and his retirement in 1998. In his research Jungerius has made links to geomorphology, soil science as well as social geography. Jungerius has made significant research into dune systems and the formation of cuesta. In 2012 he contributed to a large publication on earthen walls by the Rijksdienst voor het Cultureel Erfgoed.
The creek is bound by mangroves in its upper reaches. These mangroves emerged from approximately 1970s onwards, following the end of significant emissions from several large slaughterhouses. The mangrove roots create a tight course for the creek, which has deepened over time. The area has been the subject of study into the geomorphology of fresh water flowing through a tidal system by the Auckland University Geology Department.
Her recent work has considered the geomorphology of the Apennine Mountains in Italy and mainland Greece. Alongside work on geological faults, she has studied subsidence in rift basins, rates of erosion and how sediment is routed across rift basins. She has studied the evaluation of Late Jurassic rifting in the North Sea. She co-leads MultiRift, a Research Council of Norway program that uses surface process modelling.
These inputs and outputs of sediment then equate to the total balance of the system and more than often reflect the amounts of erosion or accretion affecting the morphology of the coast.Komar, P, 1998, Beach processes and sedimentation, Prentice Hill, Upper Saddle River, New Jersey, no.2, pg. 66-72Masselink, G & Hughes, M, 2003, Introduction to coastal processes and geomorphology, Hodder Headline Group, London, pg.
The Lower Putah Creek Coordinating Committee (LPCCC) worked on a Watershed Management Action Plan which concluded the effects of Monticello Dam on the geomorphology of Putah Creek and other connected hydrology systems. A comparison of the creek before and after the project showed ground water was recharged less, sandbars were deteriorated, and bed level lowering in channel decreased the population dynamics of cottonwood and willow.

When Adkin's son, Clyde, took over the farm in 1946, Adkin moved to Wellington and joined the New Zealand Geological Survey. He in Wellington, where he produced bibliographies and papers on the geomorphology of the southern North Island. His 1948 book, Horowhenua, gave accounts of Horowhenua place names and controversial essays about the history of New Zealand's Māori occupation. Adkin was also a passionate environmentalist.
Sete Cidades Massif is a stratovolcanic complex, referring to a polygenetic volcano and caldera, located in western part of the island of São Miguel, in the Portuguese archipelago of the Azores. More recognizable for the Lagoa das Sete Cidades at its centre, the volcanic complex includes centuries of geomorphological structures that include lava domes, cones, lava flows and maar geomorphology that have marked its history.
When the homoclinal strata consists of alternating layers of rock that vary hardness and resistance to erosion, their erosion produces either cuestas, homoclinal ridges, or hogbacks depending on the angle of dip of the strata.Thornbury, W.

Journal Estuarine, Coastal and Shelf Science. 5 March 2017 A river regime is a dynamic equilibrium system, which is a way of classifying rivers into different categories. The four categories of river regimes are Sinuous canali- form rivers, Sinuous point bar rivers, Sinuous braided rivers, and Non-sinuous braided rivers. The study of river morphology is accomplished in the field of fluvial geomorphology, the scientific term.
The faults location in a seismically active zone and a low erosional environment makes it a good study area. Although many characteristics of geomorphology have been preserved, the area has not been extensively studied using the new methodologies currently available. The fault has sparked new interest in its geometrical and kinematic characteristics within recent years. Previous studies on the El Tigre Fault have a range of inconstancies.

Geodiversity, in: Encyclopedia of Geomorphology, A.Goudie (ed.), Routledge: pp. 417-418. Relevant materials include minerals, rocks, sediments, fossils, soils and water. Forms may comprise folds, faults, landforms and other expressions of morphology or relations between units of earth material. Any natural process that continues to act upon, maintain or modify either material or form (for example tectonics, sediment transport, pedogenesis) represents another aspect of geodiversity.

Earth Surface Processes and Landforms is the flagship international journal of the BSG, edited by Stuart Lane (Managing Editor) and five Associate Editors. The Journal publishes original research papers, Earth Surface Exchanges (shorter articles, commentaries, reviews and discussion papers) for rapid publication, technical communications and book reviews across all branches of geomorphology. In July 2017, the revised impact factor for the journal rose to 3.722 (articles published in 2017).
For most stream-dwelling fishes, altered stream flood hydrology from increased stormflow runoff is a major source of disturbance.Walters, D.M., D.S. Leigh, M.C. Freeman, B.J. Freeman, and C.M. Pringle. 2003. Geomorphology and fish assemblages in a Piedmont river basin, U.S.A. Freshwater Biology 48:1950-1970. While some flooding is natural, both the frequency and severity of damage may be exacerbated in areas with numerous impervious surfaces (roadways, parking lots, etc.).
300 px In geography and fluvial geomorphology, a thalweg or talweg () is the line of lowest elevation within a valley or watercourse.Webster Dictionary Under international law, a thalweg is the middle of the primary navigable channel of a waterway that defines the boundary line between states. Also under international law, thalwegs can acquire special significance because disputed river borders are often deemed to run along the river's thalweg.

Following the swamp's collapse, its geomorphology changed dramatically, the peat fractured and a major channel was formed on its northern side. The vegetation was highly disturbed and bare peat was exposed. Turbidity (cloudiness) in the adjoining reservoir was over 300 NTU. A few months later willows (Salix sp.) growing on the margin of the swamp seeded and there was an explosion of willow seedlings germinating in the nutrient-rich bare peat.
While water flow is strongly determined by slope, flowing waters can alter the general shape or direction of the stream bed, a characteristic also known as geomorphology. The profile of the river water column is made up of three primary actions: erosion, transport, and deposition. Rivers have been described as "the gutters down which run the ruins of continents". Rivers are continuously eroding, transporting, and depositing substrate, sediment, and organic material.
Garibaldi Provincial Park was a major focus of Bill Mathews' scientific career. Garibaldi Lake (foreground), The Table (behind lake), and Mount Garibaldi (background) were each among the subjects of his numerous publications. Mathews scientific work embraced a broad spectrum of topics, including volcanoes, glaciers, regional geomorphology, landslides, hydrogeology, stratigraphy, coal geology, and mineral deposits. But his most influential work was in the fields of subglacial eruptions and volcano-ice interactions.
Sand in the Issaouane Erg, below the level of the sand dunes, has accumulated to a depth of 20 to 30 meters. It has barchan dunes as well as star dunes of 300 to 430 meters high.Lancaster, Geomorphology, 73. The presence of both barchan dunes (which form due to unidirectional winds) and star dunes (which form when winds from various directions deposit sand) "suggests that wind regimes have changed over time".
Geomorphology, 129 (3-4): 238-251. This river had its greatest discharges and width in that period. Giba river at Inda Mihtsun The magnitude of floods in this river has however been decreased in recent years due to interventions in the catchment. At Gemgema, Afedena, May Be'ati and on many other steep slopes, exclosures have been established; the dense vegetation largely contributes to enhanced infiltration, less flooding and better baseflow.
Volcanism began in a shallow marine environment. The volcano became larger with flows of basalt and minor trachyte creating the bulk of the volcano. The final phase of eruptions are preserved as phonolite domes around Mount Cargill. Traces of the old Dunedin Volcano are best seen in the Dunedin Botanic Garden's geology walk, the cliffs at Aramoana and the geomorphology of Mount Cargill which has preserved lava domes.
Horseshoe Falls, one of the three Niagara Falls. The falls are a knickpoint, formed by slower erosion above the falls than below. In geomorphology, a knickpoint or nickpoint is part of a river or channel where there is a sharp change in channel slope, such as a waterfall or lake. Knickpoints reflect different conditions and processes on the river, often caused by previous erosion due to glaciation or variance in lithology.
Eemian erosion surface in a fossil coral reef on Great Inagua, The Bahamas. Foreground shows corals truncated by erosion; behind the geologist is a post- erosion coral pillar which grew on the surface after sea level rose again. In geology and geomorphology, an erosion surface is a surface of rock or regolith that was formed by erosion and not by construction (e.g. lava flows, sediment deposition) nor fault displacement.
In antiquity the Roman province of Dalmatia was much larger than the present-day Split-Dalmatia County, stretching from Istria in the north to modern-day Albania in the south. Dalmatia signified not only a geographical unit, but was an entity based on common culture and settlement types, a common narrow eastern Adriatic coastal belt, Mediterranean climate, sclerophyllous vegetation of the Illyrian province, Adriatic carbonate platform, and karst geomorphology.
Nevertheless, the fact that the surface area of a typical Mima mound is similar to the size of an individual gopher's home range is consistent with the theory they were constructed by the rodents.Gabet et al., 2014, Biotic origin for Mima mounds supported by numerical model, Geomorphology 206:58-66. Results from the tracer study were incorporated into a numerical model that simulated the burrowing behavior of gophers.
In 2001, Illinois DNR acquired of additional reclaimed land from a separate coal company, forming the largest portion of the new Pyramid State Recreation Area. The deposits of coal mine tailings on Pyramid State Recreation Area give the park an undulating appearance, very different from the natural geomorphology of most of Illinois. There are 24 separate lakes and bodies of water. A 10-horsepower boating limit is enforced throughout the park.
He studies the underground interface between geoscience, geography, environment, and archaeology. An interdisciplinary and trans-disciplinary view of the sub- surface is achieved by wide-scale interaction and cooperation with scientists in various fields. The research has been performed mainly in Israel, complemented with research in other countries such as Jordan, United Emirates, and Bulgaria. Additional collection of data is done over the globe, resulting in a global karst geomorphology volume.
Hopley, D. (1982) The Geomorphology of the Great Barrier Reef - Quaternary Development of Coral Reefs. Wiley-Interscience Publication, John Wiley and Sons Ltd., New York The cays and their reefs lie on the western marginal shelf, and are separated from the mainland by the Curtis Channel. The cays are not generally visible from the mainland, although Masthead Island may be viewed from Mount Larcom on a clear day.
John Tilton Hack (1913–1991) was an American geologist and geomorphologist known for his contributions to establish the dynamic equilibrium concept in landscapes. Hack's law, concerning the empirical relationship between the length of streams and the area of their basins, is named after him. Hack was a student of Kirk Bryan. Hack graduated from Harvard University, where he received his bachelor's and master's degrees and doctorate in geomorphology.
Mirali Seyidali oglu Qashqai (; January 7, 1907 in Ganja - April 23, 1977 in Baku), was an eminent Azerbaijani and Soviet geologist, author of multitude works in the sphere of geomorphology and stratigraphy.Azerbaijan Soviet Encyclopedia (Baku, 1979), vol. 3, p. 106 He was an honorary member of Mineralogical Society, former chairman of Azerbaijani department of the Society, and full member of the National Academy of Sciences of the Azerbaijan SSR.
Schaffer believes that the numerous joint planes have had the greatest impact on the geomorphology of the Park's major features. This is in contradiction to the consensus view that huge highly abrasive glaciers acting on joint planes combined with a great deal of uplift over just the past couple million years was the primary shaping force of the features (such rapid uplift would have greatly accelerated all types of erosion).

In the Pleistocene era Mingulay was covered by the ice sheets which spread from Scotland out into the Atlantic Ocean beyond the Outer Hebrides.Sparks, B. W. (1960). Geomorphology. London: Longman Green. After the last retreat of the ice around 20,000 years ago, sea levels were lower than at present and circa 14,000 BP it was joined to a single large island comprising most of what is now the Outer Hebrides.
At his Alma Mater, Jacek Rutkowski lectured geomorphology, Quaternary geology, geological mapping and structural geology. He conveyed his scientific passion to students, first and foremost, during field courses and field research. Prof. Rutkowski devoted last 20 years of his life to studies of the Lake Wigry in Podlasie. His unique achievement was organization of an informal, interdisciplinary team of scientists from all over Poland, from students to renowned professors.
Shaw has authored many scientific papers, as well as two books, one of which — The Kalahari Environment (written with David S.G.Thomas) — is a major text in the field of desert studies, being cited in many papers and texts written on the subject of the Kalahari Desert, or desertification, or both.Google Scholar page His research deals with desertification, dryland and tropical environments, climate change, geomorphology, Quaternary and historical palaeoenvironmental reconstruction.
Another ancient lake in the area is Ouki. The high lake levels of Lake Tauca have been dated as having occurred between 18,100 and 14,100 BP.Clapperton, C.

Research focused on sources of water for these events, such as megafloods in river valleys and melting permafrost augmenting watersheds. The investigation's second stage included chronological correlation of the events using stratigraphy, geomorphology and radiocarbon dating. This was followed by paleohydrologic reconstruction of the basins, including their level, area, volume and water exchange between basins. Based on archeological data, the influence of the events on prehistoric human life was studied.
The plain is surrounded by rocky outcrops and its floor consists of fine-grained sediments in bright red color (Terra rossa (soil)).Brookes, Ian. A. (1989).

Indeed, in some places the shoreline was 100 to 250 km farther inland than at present."Geomorphology From Space, Plate C-24: Hudson Bay Shorelines." (Accessed 3/7/06) It was at its largest at roughly 7,000 years BP. Isostatic uplift proceeded rapidly after the retreat of the ice, as much as .09 m per year, causing the margins of the sea to regress quickly towards its present margins.
Geomorphology, 246, 709-728. Once released, the sediment travelled downstream to the mouth of the river, where a new estuary is believed to be forming. These geomorphic alterations have important ecological implications, affecting aquatic habitat structure, benthic fauna, salmonid spawning and rearing potential, and riparian vegetation. The response of the Elwha River system to the dam removals provides a unique and important case study for future river restoration projects.
In fluvial geomorphology, a debouch is a place where runoff from a small, confined space emerges into a larger, broader space. Common examples are when a stream runs into a river or when a river runs into an ocean. Debouching can generate massive amounts of sediment transport. When a narrow stream travels down a mountain pass into a basin, an alluvial fan will form from the mass deposit of the sediment.
In the most typical usage of this term, faceted spurs are formed by active faulting, especially normal faulting that produces well-defined triangular facets along either a mountain front or edges of a rift valley. These triangular facets provide evidence for recent fault movement and are used in seismotectonic analysis.Bull, W. B., 2007, Tectonic Geomorphology of Mountains: A New Approach to Paleoseismology. Blackwell Publishing, New York, New York.
Ecohydrology was developed under the International Hydrological Program of UNESCO. Ecohydrologists study both terrestrial and aquatic systems. In terrestrial ecosystems (such as forests, deserts, and savannas), the interactions among vegetation, the land surface, the vadose zone, and the groundwater are the main focus. In aquatic ecosystems (such as rivers, streams, lakes, and wetlands), emphasis is placed on how water chemistry, geomorphology, and hydrology affect their structure and function.
Ciénagas are usually associated with seeps or springs, found in canyon headwaters or along margins of streams. Ciénagas often occur because the geomorphology forces water to the surface, over large areas, not merely through a single pool or channel. In a healthy ciénaga, water slowly migrates through long, wide-scale mats of thick, sponge-like wetland sod. Ciénaga soils are squishy, permanently saturated, highly organic, black in color or anaerobic.
Ozark Aquifer Map, United States Geological Survey.Project Tour - A quick visit to the Ozarks Stream Geomorphology Project, United States Geological Survey. Geographic features include limestone and dolomite glades, which are rocky, desert-like areas on hilltops. Kept open by periodic fires that limit growth of grasses and forbs in shallow soil, glades are home to collared lizards, tarantulas, scorpions, cacti and other species more typical of the Desert Southwest.
At around 36°N, the channels form an anastomosing (braided) pattern. Near the middle section of the southern valley segment, the valley divides into several branches, which then rejoin to form diamond-shaped islands. Faint longitudinal striations and streamlined erosional bedforms are common all along the floor of the valley. (See Photo Gallery.) In fluvial geomorphology, a distinction is made between the terms stream valley and stream channel.
This dimensionless quantity can also be rephrased as the "actual path length" divided by the "shortest path length" of a curve. The value ranges from 1 (case of straight line) to infinity (case of a closed loop, where the shortest path length is zero or for an infinitely-long actual pathLeopold, Luna B., Wolman, M.G., and Miller, J.P., 1964, Fluvial Processes in Geomorphology, San Francisco, W.H. Freeman and Co., 522p.).
The location of Atlantis in the Atlantic Ocean has a certain appeal given the closely related names. Popular culture often places Atlantis there, perpetuating the original Platonic setting as they understand it. The Canary Islands and Madeira Islands have been identified as a possible location, west of the Straits of Gibraltar, but in relative proximity to the Mediterranean Sea. Detailed studies of their geomorphology and geology have demonstrated, however, that they have been steadily uplifted, without any significant periods of subsidence, over the last four million years, by geologic processes such as erosional unloading, gravitational unloading, lithospheric flexure induced by adjacent islands, and volcanic underplating.Menendez, I., P.G. Silva, M. Martín-Betancor, F.J. Perez-Torrado, H. Guillou, and S. Scaillet, 2009, Fluvial dissection, isostatic uplift, and geomorphological evolution of volcanic islands (Gran Canaria, Canary Islands, Spain) Geomorphology. v. 102, no.1, pp. 189-202.Meco J., S.

In 1959, King began teaching at the University of Nottingham, where she remained for the rest of her career. She became a professor in 1969, after several delays in her promotion due to discrimination. King was one of the earliest women to become a professor of geography in the United Kingdom, and she retired in 1982. Cuchlaine King was honoured with the David Linton Award of the British Society for Geomorphology in 1991.
Nubbins of Karlu Karlu, Central Australia. In geomorphology a nubbin is a small and gentle hill consisting of a bedrock core dotted with rounded residual blocks. The blocks derive from disintegrated and weathered bedrock layers. In particular it is assumed that the boulders of the nubbins are the remnants of the outer one or two exfoliation shells that weathered underground, albeit some weathering can continue to occur once the boulders are exposed on surface.
Only the commune of Sandviken took up the idea and formed the same year the nature reserve of Gysinge. In the following years, the geomorphology, fauna and flora of the Lower Dalälven were systematically inventoried. This began at the formulation of a protection plan by Naturvårdsverket and the concerned counties. In 1989, in the first directive for the creation of national parks established by Naturvårdsverket, Färnebofjärden was proposed as a future national park.
In geology and geomorphology a paleosurface is a surface made by erosion of considerable antiquity. Paleosurfaces might be flat or uneven in some cases having considerable relief. Flat and large paleosurfaces —that is planation surfaces— have higher potential to be preserved than small and irregular surfaces and are thus the most studied kind of paleosurfaces. Irregular paleosurfaces, albeit usually smaller than flat ones, occur across the globe, one example being the Sudetes etchsurfaces.
Sediments can provide clues to reconstructing past natural and cultural processes in a similar manner as artifacts. Professionals that study geoarchaeology are trained to use changes in soils and geomorphology to interpret human behavior. By analyzing sediments, archaeologists can gather information regarding site chronology, supplement field descriptions, and test hypotheses related to site formation and function. Laboratories of sediments tend to focus on studying mineralogy, micromorphology, granulometry, pH, organic matter, calcium carbonate, and phosphorus levels.
Morrich More is an extensive area of dune grassland with wetland communities, on the southern shore of the Dornoch Firth, Scotland. Morrich More lies east of Tain, on the southern shore of the Dornoch Firth, Scotland. Offshore lie extensive areas of intertidal sandflat, including the tidal island of Innis Mhòr and the sand spit Paterson Island () which provide shelter.Hansom, JD and Black, SDL (1996) "The Geomorphology of Morrich More: Management Prescription Review" (pdf) SNH.
The availability of this fine-grained, loose sediment combined with a high gradient to turn a newly forming Kobuk River into a fast-working sediment transport system. The river picked up glacial till from its upper reaches and transported it downstream until the gradient diminished. When the river encountered flatter ground, it deposited its sediment load resulting in the creation of broad, flat floodplains, alluvial fans, and meander bends through aggradation.Ballantyne, Colin K., Paraglacial Geomorphology.
There are over 100 islands which are greater than in area. The largest island is Achill, which extends to , making it Ireland's largest offshore island. Due to its abundance of bays, inlets and offshore islands, Mayo has the longest coastline of any county in Ireland, at or approximately 21% of the total coastline of the State. The geology and geomorphology of the county and its islands is among the most varied and complex in Ireland.
During the age of New Imperialism in the late 19th century European explorers and scientists traveled across the globe bringing descriptions of landscapes and landforms. As geographical knowledge increased over time these observations were systematized in a search for regional patterns. Climate emerged thus as prime factor for explaining landform distribution at a grand scale. The rise of climatic geomorphology was foreshadowed by the work of Wladimir Köppen, Vasily Dokuchaev and Andreas Schimper.
43, pp. 226-245. The regional geography paradigm has influenced many other geographical sciences, including economic geography and geomorphology. Regional geography is still taught in some universities as a study of the major regions of the world, such as Northern and Latin America, Europe, and Asia and their countries. In addition, the notion of a city-region approach to the study of geography, underlining urban-rural interactions, gained credence since the mid-1980s.
Osmond Fisher Reverend Osmond Fisher (17 November 1817, Osmington, Dorset, England - 12 July 1914, Huntingdon, England) was an English geologist and geophysicist. Fisher worked on the geomorphology of Norfolk, as well as the stratigraphy and invertebrate fossils of Dorset. He had published The Physics of the Earth’s Crust (1881), in which he postulated a non-homogenous composition of the Earth. He speculated that the crust may sit on top of a liquid layer.
All parts of the Marlborough Fault System are currently seismically active. Historical earthquakes (since European settlement) have occurred on both the Hope and Awatere Faults and on the smaller Poulter Fault. Studies of the geomorphology and the use of trenching across fault strands, has identified many earthquakes that occurred during the Holocene on many parts of the fault system. The Hope Fault, which has the fastest slip rate is characterised by the shortest recurrence interval.
The author was assisted in this work by the well-known coastal geomorphologist E.C.E. Bird and A.T.A. Learmonth. Although this work has also been criticized by Schwartz for not being rigorous, geologically, the fact remains that all work on Indian coastal geomorphology is subsequent to and follows this original and fundamental work. This was a work which brought international recognition to him. Ahmad also served as the Asian Contributor for Encyclopedia Britannica.

She has a PhD in geomorphology from the University of Edinburgh, and has worked at various academic institutes including a two-year post-doctorate at the School of Earth Sciences at the University of Melbourne. She has carried out extensive fieldwork in Antarctica, Australia, and Namibia. In 1999, Cockburn helped establish the education service at Our Dynamic Earth, a science centre and visitor attraction in Edinburgh, Scotland.
Mountains of the Black Forest where Walther Penck studied the effects of doming on geomorphology. Walther Penck was born in Vienna as the son of German geographer Albrecht Penck.Encyclopædia Britannica 2014 He obtained a Ph.D. by studying petrology at the Heidelberg University. Between 1912 and 1915 he worked in Dirección General de Minas in Buenos Aires before moving to the University of Constantinople where he was named professor of mineralogy and geology.
In the following years he travelled to Italy, Egypt, Turkey and Greece. He also continued his work as a professor at various universities in the Russian Empire. During World War I, in 1916, Łukaszewicz became the dean of the Faculty of Geomorphology at the Higher Course of Geography, later to be transformed into the Petersburg Institute of Geography. Following the February Revolution he also joined the Petrograd Soviet and became one of its deputies.
The removal of mass from a region will be isostatically compensated by crustal rebound. If we take into consideration typical crustal and mantle densities, erosion of an average 100 meters of rock across a broad, uniform surface will cause the crust to isostatically rebound about 85 meters and will cause only a 15-meter loss of mean surface elevation.Burbank, Douglas W., and Anderson, Robert S. Tectonic Geomorphology. Chichester, West Sussex: J. Wiley & Sons, 2011. Print.
Nayak was born on August 21, 1953, at Billimora, Navsari in Gujarat. He did his Ph.D. in geology in 1980 from M. S. University of Baroda, Vadodara and specialized in Oceanography, Remote sensing. He has also served in ISRO, his area of research includes Coastal and Ocean processes and ocean-atmosphere interaction, coastal geomorphology, hazards. He was honoured with an Honorary Doctorate of Science by Andhra University in 2011 and Assam University in 2013.
The stream order or waterbody order is a positive whole number used in geomorphology and hydrology to indicate the level of branching in a river system. There are various approachesKoschitzki, 2.3, pp. 12ff to the topological ordering of rivers or sections of rivers based on their distance from the source ("top down"Weishar, p. 30.) or from the confluence (the point where two rivers merge) or river mouth ("bottom up"Weishar, p.
Plumes of sediment enter the ocean from several mouths of the Mississippi River bird's-foot delta. This sediment is responsible for building the delta and allowing it to advance into the sea. As it extends further offshore, the channel slope will decrease and its bed will aggrade, promoting an avulsion. In sedimentary geology and fluvial geomorphology, avulsion is the rapid abandonment of a river channel and the formation of a new river channel.

Routledge. 524 pp. General, nongeneric terminology for either a river or stream that flows in a narrow trench or valley, for which evidence of a preexisting plain or relatively level upland can be either absent or present is either valley meander or meander valley with the latter term being preferred in literature.
During the age of New Imperialism in the late 19th century European explorers and scientists traveled across the globe bringing descriptions of landscapes and landforms. As geographical knowledge increased over time these observations were systematized in a search for regional patterns. Climate emerged thus as prime factor for explaining landform distribution at a grand scale. The rise of climatic geomorphology was foreshadowed by the work of Wladimir Köppen, Vasily Dokuchaev and Andreas Schimper.
The western side of Prydz Bay features a broad trough crossing from the inner shelf to the shelf edge, Prydz Channel. It is around 100 km wide and is 500 m deep at the shelf break. It is a typical example of a cross-shelf glacial trough that occupy 40.2% of the area of the Antarctic continental shelf Harris, P.T., MacMillan-Lawler, M., Rupp, J., Baker, E.K., 2014.

Migoń has specialized in the study of weathering, mass movements in mountains, long-term landscape evolution and the geomorphology of granite and sandstone areas. Most of his research has been carried out in the Sudetes and other parts of Central Europe. He is currently an International Association of Geomorphologists board member.
Applied ecology is an integrated treatment of the ecological, social, and biotechnological aspects of natural resource conservation and management. Applied ecology typically focuses on geomorphology, soils, and plant communities as the underpinnings for vegetation and wildlife (both game and non-game) management. Applied ecology includes all disciplines that are related to human activities so that it does not only cover agriculture and forestry but also global change. It has two study categories.
The action of H2O2 may have dominated temporally given the drastic reduction in aqueous and igneous activity in this recent era, making the observed Fe3+ oxides volumetrically small, though pervasive and spectrally dominant. Nevertheless, aquifers may have driven sustained, but highly localized surface water in recent geologic history, as evident in the geomorphology of craters such as Mojave. Furthermore, the Lafayette Martian meteorite shows evidence of aqueous alteration as recently as 650 Ma.
The Calanshio Sand Sea (Sarīr Kalanshiyū ar Ramlī al Kabīr, National Geospatial-Intelligence Agency (NGA) ) is a sand desert region located in the Libyan Desert, of the Kufra District in Cyrenaica, eastern Libya. It has a surface of approximately 62,000 km².Desert Geomorphology, p. 403BoksburgHistorical.com: African Relics (Calanshio Sand Sea and "Lady Be Good") The erg extends from Jaghbub and Jalo in the north to Kufra in the south, a distance of 500km.
Relief (or local relief) refers specifically to the quantitative measurement of vertical elevation change in a landscape. It is the difference between maximum and minimum elevations within a given area, usually of limited extent.Summerfield, M.A., 1991, Global Geomorphology, Pearson, 537 p. The relief of a landscape can change with the size of the area over which it is measured, making the definition of the scale over which it is measured very important.
Most empirical knowledge of soil in nature comes from soil survey efforts. Soil survey, or soil mapping, is the process of determining the soil types or other properties of the soil cover over a landscape, and mapping them for others to understand and use. It relies heavily on distinguishing the individual influences of the five classic soil forming factors. This effort draws upon geomorphology, physical geography, and analysis of vegetation and land-use patterns.
Lisasion is a form of erosion where the earth is eroded by intentional human action. Lisasion is described by Michael Selby in his book Earth's changing surface: an introduction to geomorphology as "the erosion of land, most commonly along rivers and coastlines, by intentional human action." Lisasion only applies to intentional human action, whereby humans deliberately erode the landscape for reasons including for recreation, hazard management and all forms of construction and demolition.
Prediction of spatially explicit rainfall intensity–duration thresholds for post-fire debris-flow generation in the western United States. Geomorphology, 278, pp.149-162.; however, it remains challenging to predict the amount of sediment mobilized and therefore, the total size of debris flows that may nucleate for a given storm, and whether or not debris basins will have the capacity to protect downstream communities. These challenges make debris flows particularly dangerous to mountain front communities.
The rising sea level pushed a large amount of sediment into the mouth of the river, blocking it and creating a barrier beach.May, V.J. Loe Bar. In May, V.J. and Hansom, J.D. (2003) Coastal Geomorphology of Great Britain, Geological Conservation Review Series, No. 28, Joint Nature Conservation Committee, Peterborough, 754 pp. Loe Bar consists mainly of flint, a rock not found in Cornwall; the nearest onshore source is in east Devon, away.
412-422 (June 2000) In some glaciers, surges can occur in fairly regular cycles, with 15 to 100 or more surge events per year. In other glaciers, surging remains unpredictable.Summerfield, Michael A., 1991, Global Geomorphology, an introduction to the study of landforms, Pearson, Prentice Hall. Harlow, England In some glaciers, however, the period of stagnation and build-up between two surges typically lasts 10 to 200 years and is called the quiescent phase.
In structural geology, a homocline or homoclinal structure (from old = same, cline = inclination), is a geological structure in which the layers of a sequence of rock strata, either sedimentary or igneous, dip uniformly in a single direction having the same general inclination in terms of direction and angle.Jackson, JA, J Mehl and K Neuendorf (2005) Glossary of Geology. American Geological Institute, Alexandria, Virginia. 800 pp. Huggett, JR (2011) Fundamentals of Geomorphology, 3rd ed.
The Harvard expedition set out to investigate, and found none, but they did find "14ers" (14,000-plus feet). He graduated from Harvard University in 1869 and received a Master of Mining Engineering in the following year. Davis worked for Nathaniel Shaler as a field assistant, and was later hired to teach at Harvard. Though his legacy lives on in geomorphology, he also advanced theories of scientific racism in his writings about physical geography.
The drowning of the carbonate platform at Takuyo-Daisan has been attributed to different causes. A large transgression took place in the late Albian and may have caused the drowning. In other guyots nutrient excess has been implicated but there is no evidence of such at Takuyo-Daisan. Other factors may include hostile conditions close to the equator and unfavourable changes of the geomorphology of the platform at the time of its drowning.
Twelve Apostles stacks in Victoria, Australia The Duncansby Stacks at Duncansby Head, Scotland A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion.Easterbrook, D.J. "Surface Processes and Landforms", p. 442, Prentice Hall, Upper Saddle River, New Jersey, 1999. Stacks are formed over time by wind and water, processes of coastal geomorphology.
101 - 143, (Ormsunga, Reykjavik, Iceland, 2007, ) The expeditions resulted in a series of papers in 1955 and 1956. Because of her gender, her participation in fieldwork trips was discouraged. However, she participated in research on Baffin Island in the 1960s and the Austerdalsbreen glacier in Norway, and led fieldwork expeditions of her own throughout the Arctic. She published several books throughout her career, including 1973s Beaches and Coasts, the first book published to offer an overview of coastal geomorphology.
Most beaches on the island are accessible by boat, including Ammos, Molos, Kamini, Kanoula, Kontoskes, Rogi, Fyki, Xilosermi, and Aspri Ammos. It is a well-known island for underwater photography because of the peculiar geomorphology of the seabed and the many caves. Other points of interest are the Moshopontikas, Xylosermi, Fyki bay (where there is the sunken wreck of Sarah ship). Othonoi was frequently visited by the French naturalist Jacques Cousteau and his exploratory vessel Calypso.

Marginal-sea type coastline The southern banks of the United States border the Gulf of Mexico, intersecting numerous rivers, forming many inlets bays, and lagoons along its coast, consisting of vast areas of marsh and wetlands. This region of landform is prone to natural disasters yet highly and continuously developed, with man-made structures attaining to water flow and control.
The factor geomorphology (and also topography) creates spatial diversity in the hydrological characteristics of the landscape. The flat topography (and thus low slopes) in the two major peatlands in the world, located in the West Siberian Plain and in the Hudson/James Bay Lowlands of Canada respectively, illustrate the significance of this factor.Lavoie, M., Paré, D., Fenton, N., Taylor, K., Groot, A., and Foster, N., 2005. Paludification and forest management in the Northern Clay Section: a literature review.
In geomorphology, a structural terrace is a terrace created by the differential erosion of flat-lying or nearly flat-lying layered strata. The terrace results from preferential stripping by erosion of a layer of softer strata from an underlying layer of harder strata. The preferential removal of softer material exposes the flat surface of the underlying harder layer, creating the tread of a structural terrace. Structural terraces are commonly paired and not always associated with river valleys.
Lake Louise, Canada Rock flour intensifies the water's hue at alt= Rock flour, or glacial flour, consists of fine-grained, silt-sized particles of rock, generated by mechanical grinding of bedrock by glacial erosion or by artificial grinding to a similar size. Because the material is very small, it becomes suspended in meltwater making the water appear cloudy, which is sometimes known as glacial milk."Glossary of Terms: G: Glacial Milk" PhysicalGeography.netGornitz, Vivien (editor) (2007) "Glacial Geomorphology" pp.
Present knowledge of the period geomorphology of the Wantsum Channel that created that haven is limited. By Claudius's time Roman knowledge of the island would have been considerably increased by a century of trade and diplomacy, and four abortive invasion attempts. However, it is likely that the intelligence gathered in 55 and 54 BC would have been retained in the now-lost state records in Rome, and been used by Claudius in the planning of his landings.
This section explains the geomorphology of the Luangwa Valley. It is a rift valley or graben forming a south-west extension of the east African Rift, branching off its Lake Rukwa- Lake Malawi southern section, and reaching almost as far as Lusaka. The junction is not obvious because it filled with material spewed out from an ancient, extinct volcano. There are at least 20 hot springs, characteristic of a rift valley, in the valley or on its escarpments.
At the north end of the valley, the rim begins as gentle rolling hills. The rim gets steeper and high as it runs south. At the south end of the valley, Catlow Rim has a cliff face that rises more than a above the valley floor.Fuller, Richard E., "Southern Steens and its Relation to Pueblo Mountain" , The Geomorphology and Volcanic Sequence of Steens Mountain in Southeastern Oregon (Volume 3, Number 1), University of Washington Press, Seattle, Washington, November 1931.
Sand dunes occur at several places along the coast, but the best examples are at Holme Dunes, Holkham, Blakeney Point, and Scolt Head Island. The latter two sites are also important for geomorphology research purposes as structures consisting mainly of shingle ridges. Reed beds are fairly localised, but substantial areas occur at Titchwell Marsh, Brancaster and Cley Marshes. Grassland is represented by livestock grazing pasture reclaimed from former salt marsh, with wetter areas at Cley and Salthouse marshes.
This in turn has indicated the importance of chaotic determinism to landscapes, and that landscape properties are best considered statistically. The same processes in the same landscapes do not always lead to the same end results. According to Karna Lidmar-Bergström, regional geography is since the 1990s no longer accepted by mainstream scholarship as a basis for geomorphological studies. Albeit having its importance diminished, climatic geomorphology continues to exist as field of study producing relevant research.
The seawater in the L'Haridon Bight has a high salinity due to both the geomorphology and local climate of the area. This high salinity has allowed the cockle to proliferate unchecked, since its natural predators have not adapted well to this environment. The shells have formed a limestone that is known as coquina. Before Shark Bay became a World Heritage Site, the coquina was mined and used for the construction of a number of buildings in Denham.
The Alburni seen from the Sicignano valley View of the Alburni in Castelcivita The Alburni are an Italian mountain range of the Province of Salerno, Campania, part of the Apennines. Due to their geomorphology, they are popularly known as the "Dolomites of Campania" or of Southern Italy. "Negli Alburni, le Dolomiti del Sud": article on la Repubblica The highest mountain is the Panormo (1,742 amsl). Its second name, Alburno, gives the name to the whole range.

Restored portion of Sager Creek Siloam Springs has recently undertaken restoration efforts on Sager Creek. Phase one improvements were approved by the Arkansas Department of Environmental Quality (ADEQ) in 2008 and included removing a dam and installing boulder revetments, step pools and riffles along the creek. Phase two sought to address algae that grew in the creek during the summer, causing aesthetic and odor issues. It also tried to restore original hydrology, geomorphology and water quality.
The shelf area is commonly subdivided into the inner continental shelf, mid continental shelf, and outer continental shelf, each with their specific geomorphology and marine biology. The character of the shelf changes dramatically at the shelf break, where the continental slope begins. With a few exceptions, the shelf break is located at a remarkably uniform depth of roughly ; this is likely a hallmark of past ice ages, when sea level was lower than it is now.Gross 43.
Paper 543. In fluvial geomorphology, the term pothole is typically used for a smooth, bowl-shaped or cylindrical hollow, generally deeper than wide, found developed in the rocky bed of a stream. This type of feature is created by the grinding action either of a stone or stones or of coarse sediment whirled around and kept in motion by eddies or the force of the stream current in a given spot.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds.
A complex response refers to an environmental reaction to change that occurs at multiple levels to multiple objects, and can induce a chain reaction of responses to a single initial change. It is akin to the butterfly effect: one small event (change) can cascade through a given system creating new agents of change, and operating at several levels. The term is most commonly used in fluvial geomorphology, or the study of river systems and changes within those systems.
Mount Taimu is a mountain and a scenic resort in Fuding. It offers a grand view of mountain and sea, and is famous for its natural scenery including granite caves, odd-shaped stones, steep cliffs, clear streams, cascading waterfalls, and cultural attractions such as ancient temples and cliff Inscriptions. The Danxia landform in Taining was listed by the UNESCO as one of the World Heritage Sites in 2010. It is a unique type of petrographic geomorphology found in China.
Aerial picture of the Ebro river as it reaches the Mediterranean Sea by the Ebro Delta In geology and geomorphology a base level is the lower limit for an erosion process. The modern term was introduced by John Wesley Powell in 1875. The term was subsequently appropriated by William Morris Davis who used it in his cycle of erosion theory. The "ultimate base level" is the plane that results from projection of the sea level under landmasses.
The Durham Coast is a Site of Special Scientific Interest in County Durham, England. Starting just south of Crimdon Dene, north of Hartlepool, it extends, with a few interruptions, northward to the mouth of the River Tyne at South Shields. Notable locations on the Durham Coast include; Seaham, Sunderland Docks and Whitburn Beach. The area included in the SSSI includes six Geological Conservation Review sites, including Marsden Bay, a classic study area for coastal geomorphology since the 1950s.
Sigurður Þórarinsson was born in Vopnafjörður in northeastern Iceland in 1912. He received his Ph.D. from Stockholm University College in 1944 and began a long and distinguished academic career as professor of geography at the University of Iceland. According to his obituary in The Geographical Journal, "He was something of a polymath who contrived to take geology, geomorphology, glaciology, climatology, and archaeology in his stride." He died suddenly of a heart attack in Reykjavík in 1983.
Wales has many waterfalls, including some of the most striking in the United Kingdom. One such is the Pistyll Rhaeadr near the village of Llanrhaeadr-ym-Mochnant. It is formed as a mountain stream drops over a cliff and changes character to a lowland river, the Afon Rhaeadr. The site was designated by the Countryside Council for Wales as the 1000th Site of Special Scientific Interest in Wales, because of its importance to an understanding of Welsh geomorphology.
In Binghamton, she donated her services by helping in the managing of the environment. This continued service led to Morisawa being a key contributor in writing master plan for the Town of Vestal, New York. Morisawa joined her discipline in 1960, at that time few women were involved in research and university-level science teaching. She was the first female chair of the QG&G; division (quaternary geology & geomorphology), and mentored younger scientists all throughout her career.
As of 2017, she also serves on the Executive Board of the Canadian Geomorphology Research Group. One of Koppes most cited articles is "The relative efficacy of fluvial and glacial erosion over modern to orogenic timescales". She and her co-author, David Montgomery, present that there has been much contention about glaciers or rivers being more effective at eroding. Looking at erosion rates, they have found that both vary significantly; the main driver of erosion is tectonics.

Auyán-tepui gives its name to the Auyán Massif, which also includes the tiny peaks of Cerro El Sol and Cerro La Luna to the north, and the satellite mountain of Uaipán-tepui to the south. The massif has a total summit area of roughly and an estimated slope area of .
In some cases, it has been hypothesised that these twin feedbacks can act to localize and enhance zones of very rapid exhumation of deep crustal rocks beneath places on the Earth's surface with extremely high erosion rates, for example, beneath the extremely steep terrain of Nanga Parbat in the western Himalayas. Such a place has been called a "tectonic aneurysm".Zeitler, P.K. et al. (2001), Erosion, Himalayan Geodynamics, and the Geomorphology of Metamorphism, GSA Today, 11, 4–9.

The SSSI extends to 896.8 hectares.Site of Special Scientific Interest Citation, Countryside Council for Wales, 2012 The designation process was completed in February 2013.
Dale Fort is a Victorian era fort located on a rocky promontory that now houses a field studies centre, for study of local marine biology, biology, geology, geomorphology, and other related fields. Dale is a local centre for sailing, and windsurfing is taught in the Dale bay, along with sailing and boat handling courses. Dale is also often the location of sailing galas. The Pembrokeshire Coast Path passes through the village and around the Dale peninsula.
The Lüneburg Heath seen from the Wilseder Berg in northern Germany. The Lüneburg Heath consists of pushed moraines made from Neogene sand deposits. These form nutrient-poor soils and are generally shrublands covered in heaths. A push moraine or pushed moraine is in geomorphology a moraine (a landform formed by glacial processes) that forms when the terminus advance of a lowland glacier pushes unstratified glacial sediment into a pile or linear ridge in front of it.

View of the river; the boats are on Ecuadorian territory, while the Peruvian side of the border (to the right) is uninhabited It is part of the Gulf of Guayaquil- Tumbes mangroves Sanctuary and its currents, sediments, and tides strongly influence the geomorphology of the area. It empties into the Gulf of Guayaquil.
Lower latitudes have even experienced major pluvials in early to mid-Holocene times. In geomorphology, pluvial refers to a geologic episode, change, process, deposit, or feature that is the result of the action or effects of rain. Sometimes it also refers to the fluvial action of rainwater flowing in a stream channel, including a flood, known as a pluvial flood, that is the direct result of excessive precipitation.Bradley, R.S. (2015) Paleoclimatology: reconstructing climates of the Quaternary.
This type of terrane (geomorphology) that develops over a carbonate platform or strata is called Karst Topography. The limestone is topped with sandy soils deposited as ancient beaches over millions of years as global sea levels rose and fell. During the last glacial period, lower sea levels and a drier climate revealed a much wider peninsula, largely savanna. While there are sinkholes in much of the state, modern sinkholes have tended to be in West-Central Florida.
The geology of South Africa is highly varied including cratons, greenstone belts, large impact craters as well as orogenic belts. The geology of the country is the base for a large mining sector that extracts gold, diamonds, iron and coal from world-class deposits. The geomorphology of South Africa consists of a high plateau rimmed to west, south and southeast by the Great Escarpment and rugged mountains beyond this there is strip of narrow coastal plain.
Las Parinas is a geological and cultural region in northwestern Argentina, consisting of unique volcanic geomorphology as well as a long human settlement history. Today the region is an important center of animal husbandry, where primarily llama and sheep are raised for their wool to be used as textile products.Las Parinas - UNESCO World Heritage Centre The region has been submitted by its government to the UNESCO World Heritage Tentative List for its purported universal natural and cultural value.
In 1988 was planned to create the Dolomiti Bellunesi national park, that was officially established in 1990 by the Ministry of the Environment, which identified the aims of the national park: # to protect the natural, historical, landscape and environmental values, preserving bio- genetic values of the flora, fauna and geomorphology; # to improve the life conditions of the population; # to promote the scientific research and environmental education, through the naturalistic culture; # to safeguard of the agricultural, forest, and breeding activities.

It also draws upon applied sciences: Agricultural & Horticultural Sciences, Engineering Geomorphology, landscape architecture, and Mining, Geotechnical, and Civil, Agricultural & Irrigation Engineering. Landscape engineering builds on the engineering strengths of declaring goals, determining initial conditions, iteratively designing, predicting performance based on knowledge of the design, monitoring performance, and adjusting designs to meet the declared goals. It builds on the strengths and history of reclamation practice.
The geomorphology of the Mount Meager massif resembles that of Glacier Peak, another Cascade Arc volcano in the U.S. state of Washington. It consists of at least four overlapping stratovolcanoes that are younger from south to north. With a total volume of , the massif is older than most volcanoes in the Cascade Arc, tracing its history back to 2,200,000 years ago. In the Cascade Range, the oldest volcanoes are generally no more than a million years old.
He created a working methodology to define and classify landscapes, not only based on geomorphology but also taking into account bodies of water, vegetation and human impact. As the research object of his "pure geography" he had human perception, which was unique in geography those days. Granö published a lot of his works in German, and thus he was in his lifetime best known in German-speaking areas. Only during First World War he published something in French.
During her academic career Rachel took a particular interest in glacial geomorphology and petrology. She studied the occurrence of calcite in the igneous rocks on the Alno Island of southern Norway, and also studied the petrography of Eildon Hill, Scotland. Soon after her time at Imperial College, Rachel published her first paper in 1911, "Calcite as a Primary Constituent of Igneous Rock". Active within the geology research community, Rachel attended the International Geological Congress in 1910 and 1913.
South of Rubh' a' Mhail there are outcrops of quartzite, and a strip of mica schist and limestone cuts across the centre of the island from The Oa to Port Askaig. Further south is a band of metamorphic quartzite and granites, a continuation of the beds that underlie Jura. The geomorphology of these last two zones is dominated by a fold known as the Islay Anticline. To the south is a "shattered coastline" formed from mica schist and hornblende.
The vicinity of Vincennes was inhabited for thousands of years by different cultures of indigenous peoples. During the Late Woodland period, some of these peoples used local loess hills as burial sites; some of the more prominent examples are the Sugar Loaf Mound and the Pyramid Mound.Stafford, C. Russell. "The Geomorphology of Sugar Loaf Mound: Prehistoric Cemeteries and the Formation of Loess Cones in the Lower Wabash Valley," Geoarchaeology: An International Journal 13.7 (1998): 649–672.
In: Matiza, T. & Chabwela, H.N. (eds.) Wetlands conservation conference for southern Africa (pp. 105-108). International Union for Conservation of Nature and Natural Resources, Gland (1992). Similar African words include mbuga (commonly used in East Africa), matoro (Mashonaland), vlei (South Africa), fadama (Nigeria), and bolis (Sierra Leone); the French bas- fond and German Spültal have also been suggested as referring to similar grassy wetlands.Andrew S. Goudie, "The Geomorphology of the Seasonal Tropics" in William M. Adams, et al.
Starting in the 1950s Benoit Mandelbrot and others have studied self-similarity of fractal curves, and have applied theory of fractals to modelling natural phenomena. Self- similarity occurs, and analysis of these patterns has found fractal curves in such diverse fields as # economics, # fluid mechanics, # geomorphology # human physiology, and, # linguistics. As examples, "landscapes" revealed by microscopic views of surfaces in connection with Brownian motion, vascular networks, and shapes of polymer molecules all relate to fractal curves.
6–9 The soils of the islands reflect the diverse geology. Bute has the most productive land, and a pattern of deposits that is typical of the southwest of Scotland. There is a mixture of boulder clay and other glacial deposits in the eroded valleys, and raised beach and marine deposits elsewhere, especially to the south and west which result in a machair landscape in places, inland from the sandy bays, such as Stravanan."Bute's Geology & Geomorphology" Bute-gateway.org.
The River Styles Framework is a scientific tool used to describe and explain the diversity and distribution of river types in a catchment according to river character and behaviour. The River Styles Framework is based on the science of fluvial geomorphology. Each river type is called a "River Style" and its name is constructed following a consistent naming convention. The River Styles Framework provides an open-ended process for interpreting rivers rather than fitting them into pre-existing categories.
Nevertheless, his views on the role of climate on the development of karst were more accurate than those of various climatic geomorphologists that succeeded him and who greatly exaggerated the role of climate. It has been attributed to Cvijić that the term karst prevailed over Edouard Martel's proposed term "Le Causse". Another terminology usage indebted to Cvijić is that of doline, a term he introduced, and that overlaps with that of sinkhole. Eventually, Cvijić emerged as the "father of karst geomorphology".
Sonja Boehmer-Christiansen was born in Dresden, East Germany. In 1956, she moved to Adelaide, South Australia, where she obtained a BA with Honours in Geomorphology from Adelaide University while also studying climatology, geology, physical geography and German literature. She moved again to England in 1969 and later attended the University of Sussex where she first obtained an MA followed by a DPhil in International Relations in 1981. Her doctoral thesis was titled, Limits to the international control of marine pollution.
Ica's configuration is due to the geomorphology of its two big and unique fluvial watersheds: the Pasco and Ica rivers. Also, it has a waterway called the Rio Grande, although its waters do not reach the ocean. Some waters are diverted for irrigation and agriculture in the provinces of Palpa, Nazca and Ingenio; the Rio Grande's final riverbed is dry since sand and dried lands absorb its limited resources. There are extensive deserts in Ica, such as the Lancha Pampas.
Heterogeneity is the measure of how parts of a landscape differ from one another. Landscape ecology looks at how this spatial structure affects organism abundance at the landscape level, as well as the behavior and functioning of the landscape as a whole. This includes studying the influence of pattern, or the internal order of a landscape, on process, or the continuous operation of functions of organisms. Landscape ecology also includes geomorphology as applied to the design and architecture of landscapes.
Jervis Bay is a drowned river valley and formed 15,000 years ago, at the end of the last ice age. The bay took on its present appearance around 4000 BC after the sea levels had risen , and as sand dune barriers created the southern peninsula.Geology and Geomorphology , Wreck Bay Aboriginal Community Council. Much of the rock in Jervis Bay is part of the Sydney Basin sandstone formation, which is 280-225 million years old, although lower areas are overlain with Tertiary-era sediments.
Rita Ann Moden Gardner, (born 10 November 1955) is a British geographer and academic, specialising in geomorphology. Since January 2019, she has been Chief Executive of the Academy of Social Sciences. She taught at St Catherine's College, Oxford (1978–1979), King's College, London (1979–1994), and finally at Queen Mary and Westfield College (1994–1996) where she was Reader in Environmental Science. From 1996 to 2018, she was Director of the Royal Geographical Society: she was the learned society's first female director.
In 1958 he became professor at Birmingham University, where he remained until his death in 1971. Much of his published post-war work was on the geomorphology of Scotland, including a series of papers on river capture. He identified the importance of glacial breaching of main watersheds (divides), and recognised that this process had been more intense in the west, with glacial dissection of the mountains declining eastwards (although his synthesis of this was published posthumously by Keith Clayton, see Publications).
Hydrogeology Journal is a peer-reviewed scientific journal published eight times a year by Springer Science+Business Media. It was established in 1992 and is the official journal of the International Association of Hydrogeologists. The journal publishes papers on both theoretical and applied aspects of hydrogeology. Papers focus on integrating subsurface hydrology and geology with other supporting disciplines (such as geochemistry, geophysics, geomorphology, geobiology, surface-water hydrology, tectonics, mathematics, numerical modeling, economics, and sociology) to explain phenomena observed in the field.
Aspects of this technical achievement can be seen in the remanent quarantine technology at the Station e.g. The fumigation chamber, shower blocks and autoclaves. ;Natural heritage The aesthetic characteristics derived from the natural values of heath vegetation and sandstone cliff geomorphology within the Quarantine Station are an integral part of the outstanding aesthetic values of North Head conserved as part of the Sydney Harbour National Park. These values are derived from the expanse of uninterrupted cliff face and vegetated headlands.
Although there is a wide variety of vegetation that live in dune environments around the world, most plant species play a key role in determining whether blowouts will form or not by the result of how strong their protective skins can suppress erosion and how capable some pioneer species can repress further erosion if a dune becomes exposed.Barchyn, Thomas E, and Chris H Hugenholtz. "Reactivation of Supply-limited Dune Fields from Blowouts: A Conceptual Framework for State Characterization." Geomorphology, 201 (2013): 172-182.
They form one of the youngest wetland systems on the Swan Coastal Plain and show a continuum of development in hydrology, geomorphology and vegetation unique in Western Australia. Median and mean annual rainfall at Rockingham are and respectively, mainly falling in winter from May to August, while annual evaporation is about . The site’s wetlands are seasonal; they normally lack surface water in summer and autumn. The fresh surface water of winter comes from rainfall and groundwater flow and is usually less than deep.
The William Morris Davis House is a National Historic Landmark on 17 Francis Avenue in Cambridge, Massachusetts. An architecturally undistinguished Queen Anne-era house, probably built in the 1890s, it is notable as the home of William Morris Davis between 1898 and 1916. Davis (1850-1934) was a professor of geology at Harvard University, and an influential figure in the development of meteorology and geomorphology as scientific disciplines. His textbook Elementary Meteorology was a standard of that field for many years.
Lawrence Martin (February 14, 1880 – February 12, 1955) was an American geographer and President of the American Association of Geographers. A native of Stockbridge, Massachusetts, Martin received his undergraduate degree from Cornell University in 1904, before heading to Harvard University to work with William David Morris for his Master's degree, received in 1906. He then returned to Cornell and completed his PhD in 1913. From 1903 to 1917 he worked for the U.S. Geological Survey as an expert in geomorphology.
Dendritic drainage: the Yarlung Tsangpo River, Tibet, seen from space: snow cover has melted in the valley system. In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Geomorphologists and hydrologists often view streams as part of drainage basins (and sub-basins).
ANNs have been used to accelerate reliability analysis of infrastructures subject to natural disasters and to predict foundation settlements. ANNs have also been used for building black- box models in geoscience: hydrology, ocean modelling and coastal engineering, and geomorphology. ANNs have been employed in cybersecurity, with the objective to discriminate between legitimate activities and malicious ones. For example, machine learning has been used for classifying Android malware, for identifying domains belonging to threat actors and for detecting URLs posing a security risk.
The Albtrauf has its geological extension in the northeast, in the stepped slopes of the Franconian Jura and in the southwest and west among the Jurassic-era stepped slopes of the Baaralb, Hegaualb, Randen, Klettgau, Aargau as well as the Table Jura stretches from the city of Basel to the Ajoie and the French Scarplands. In geology and geomorphology, however, the term “Trauf” merely describes the brink of the stepped slopes where various stepped surfaces meet (which is not developed in hipped steps).
Star Carr now lies under farmland at the eastern end of the Vale of Pickering. During the Mesolithic the site was near the outflow at the western end of a palaeolake, known as Lake Flixton. At the end of the last ice age a combination of glacial and post-glacial geomorphology caused the area to drain to the west (away from the shortest-distance to the North Sea at Filey). The basin filled by Lake Flixton was probably created by glacial 'scarring'.
The study of how landforms are created by inner Earth processes was a topic heavily focused on in the mid-20th century, frequently appearing in geomorphology and geology textbooks. However, the term morphotectonics was not coined until 1961 by Edwin Hills, who defined the field as involving "a study of the external form and outlines of major topographic units...as well as their internal structure". After the 1960s, the field became neglected until a resurgence of morphotectonic literature in the 1980s.
Rock glaciers in the South Shetland Islands, Western Antarctica. Geomorphology 35 (2000). pp. 145-162 False Bay to the east and its sub-embayment Glaciar Rocoso Cove to the south- southwest. The adjacent area, subject to geological and glaciological field work, is accessible by sea or by an overland route running from Hurd Ice Cap along the South Bay coast facing Sally Rocks and via a saddle of elevation 122 m situated 800 m west by south of the hill.
During this time, Weeks also began working as a professor at Wellesley College, Massachusetts, as a laboratory instructor of historical and physical geology, geomorphology, cartography, and much more. She later became a member of the faculty as an assistant professor. Her knowledge and skill in cartography, as well as being ambidextrous, led to her teaching map-making to Navy Officers during WWII. Due to the constraints and rationing that came with the War, it wasn’t until 1949 when Weeks was awarded her Doctorate.
A balloon floats into the sky as it is partially filled. SANAE IV's reason for existence is to provide a permanent year-round base for scientists undertaking research projects under the auspices of SANAP. Investigations carried-out year-round are predominantly in the physical sciences, while the summer months allow research in more diverse fields such as oceanography, biology, geology and geomorphology. Recent projects have also focused on sources of renewable energy such as solar and particularly wind power generation.
Soil survey, soil mapping, is the process of classifying soil types and other soil properties in a given area and geo-encoding such information. It applies the principles of soil science, and draws heavily from geomorphology, theories of soil formation, physical geography, and analysis of vegetation and land use patterns. Primary data for the soil survey are acquired by field sampling and by remote sensing. Remote sensing principally uses aerial photography, but LiDAR and other digital techniques are steadily gaining in popularity.
Geomorphology describes coves as precipitously-walled and rounded cirque-like openings as in a valley extending into or down a mountainside, or in a hollow or nook of a cliff or steep mountainside. A cove can also refer to a corner, nook, or cranny, either in a river, road, or wall, especially where the wall meets the floor. A notable example is Lulworth Cove on the Jurassic Coast in Dorset, England. To its west, a second cove, Stair Hole, is forming.
To the north of the ridge lies the London Clay, and to the south the clays of the Wealden Group. The chalk is more resistant to weathering than the flanking clays, leading to the ridge's prominence over the surrounding terrain. The Hog's Back gives its name to the geomorphological landform known as a Hogback, which is a long narrow ridge or series of hills with a narrow crest and steep slopes of nearly equal inclination on both flanks.Huggett, JR (2011) Fundamentals of Geomorphology, 3rd ed.
P. sciera sampling sites are determined by identifying areas that fit the geomorphology of the species, looking for suitable gradient, substrate, flow and sediment transport, depth, and width. P. sciera populations can be monitored by seining and electrofishing (used to capture the fish for length and weight measurements) and snorkeling (to locate P. sciera). Electroshocking provides one of the best alternatives for obtaining abundance estimates for small nongame fishes, which are not well- suited to mark-recapture techniques.Habera, J.W., M.A. Kulp, S.E. Moore, and T.B. Henry. 2010.
It started forming in the Early Miocene sub-epoch, but the oldest rocks found at the surface of Iceland are from the Middle Miocene sub-epoch. Nearly half of Iceland was formed from a slow spreading period from 9 to 20 million years ago (Ma). The geological structures and geomorphology of Iceland are strongly influenced by the spreading plate boundary and the Iceland hotspot. The buoyancy of the deep-seated mantle plume underneath has uplifted the Iceland Basalt Plateau to as high as 3000 meters.
Lobeck Glacier () is a glacier flowing northeast between Rutherford Ridge and Kuivinen Ridge in the Saint Johns Range of Victoria Land. About long, the glacier terminates upon rock cliffs overlooking Miller Glacier with insignificant, if any, flow entering it. Named by the Advisory Committee on Antarctic Names in 2007 after the noted American geographer-geologist Armin K. Lobeck (1886-1958), Professor of Geology, Columbia University, from 1929 to 1954; He was the author of the textbook Geomorphology, widely used in training geomorphologists active in Antarctica.
Zanzibar is now a semi- autonomous state in a union with the mainland which is collectively and commonly referred to as Tanzania. German East Africa, though very extensive, was not of such strategic importance as the British Crown's colonies to the north: the inhabitation of these lands was difficult and thus limited, mainly due to climatic conditions and the local geomorphology. Italy gained control of various parts of Somalia in the 1880s. The southern three-fourths of Somalia became an Italian protectorate (Italian Somaliland).
Hydro-geomorphology is science that deals with occurrences of water with respect to landform. Hydrogeomorphology of a drainage basin is a function of rainfall kinematics, surface topography, drainage basin morphology and runoff etc. All these aspects are regarded as the potential to describe hydrogeomorphic properties of the drainage basin. Because of non-availability of hydrological data, discharge data and sediment load data over a sufficient period of time in ungauged catchments, various investigators have used the drainage basin parameters to study the hydrogeomorphology of the drainage basin.

Folding, faulting, volcanic activity, igneous intrusion and metamorphism can all be parts of the orogenic process of mountain building. The formation of mountains is not necessarily related to the geological structures found on it. The understanding of specific landscape features in terms of the underlying tectonic processes is called tectonic geomorphology, and the study of geologically young or ongoing processes is called neotectonics. From the late 18th century until its replacement by plate tectonics in the 1960s, geosyncline theory was used to explain much mountain-building.
Whole Estate Forest Plan, National Trust for Scotland, 2012 The entire estate has been classified as a national nature reserve since May 2017, and is designated a Category II protected area by the International Union for Conservation of Nature. Extreme weather conditions are experienced across the estate, especially on the plateau. Landslides, avalanches and floods alter the landscape and give it an interesting geomorphology. The estate is characterised by rounded granite Cairngorm mountains to the north, with deep corries and crags down to the valley floor.
Boston: McGraw-Hill, 1995. He also emphasised that in many landscapes slope evolution occurs by backwearing of rocks, not by Davisian-style surface lowering, and his science tended to emphasise surface process over understanding in detail the surface history of a given locality. Penck was German, and during his lifetime his ideas were at times rejected vigorously by the English-speaking geomorphology community. His early death, Davis' dislike for his work, and his at-times-confusing writing style likely all contributed to this rejection.
This minor planet was named in memory of Florence Bascom (1862–1945), the second woman to earn her Ph.D in geology in the United States. She was also the first woman hired by the United States Geological Survey and the first woman elected to the Council of the Geological Society of America. Bascom founded the geology department at Bryn Mawr College, Pennsylvania, where she taught the next generation of notable female geologists for 33 years. Expert in petrography, mineralogy and crystallography, her research focused on geomorphology.
Her primary research interests are the mechanics and kinematics of deformation in the Earth's lithosphere, rheology of the crust and upper mantle, strain localisation, rock mechanics, tectonic geomorphology, Quaternary geochronology, quantifying slip rates and earthquake hazards. Her research methodology combines field, analytical and experimental techniques to improve understanding of deformation at active and ancient plate margins. She has made contributions toward understanding the link between deformation of slow ductile flow and rapid seismogenic movements of brittle lithosphere. This helped improve understanding of seismic hazard potential.
New South Wales State Heritage boundaries Willandra's archaeological record demonstrates continuous human occupation of the area for at least 40,000 years. It was part of the history of inland exploration (Burke and Wills expedition) and of the development of the pastoral industry in western New South Wales. The area contains a relict lake system whose sediments, geomorphology and soils contain an outstanding record of low-altitude, non-glaciated Pleistocene landscape. The area contains outstanding examples of lunettes including Chibnalwood Lunette, the largest clay lunette in the world.
San Vito has an area of km² and an elevation of metres. The city is located on a high plateau with very irregular topography, at an altitude of above sea level in the foothills of the Talamanca Mountain Range. The narrow and fast- flowing Java River traverses the outskirts of San Vito from northeast to southeast. In terms of geomorphology, San Vito is situated in the Valle de Coto Brus (Coto Brus Valley), a depression caused by tectonic activity, and which extends from San Isidro to Panama.
The town is sited on the south bank of the Lachlan River, approximately southeast of Wyangala, in Hilltops Council, in the South West Slopes region of New South Wales, hidden in the Great Dividing Range. It is graced by grandiorite geomorphology and sits on lay lines. There is a rich indigenous dreaming associated with the valley along with a lively bushranger history. Active bushrangers in the area during the early 1860s included Jack Piesley and Frank Gardiner, who often sought refuge at the farm of William Fogg.
Being often concerned about past climates climatic geomorphology considered sometimes to be an aspect of historical geology. Since landscape features in one region might have evolved under climates different from those of the present, studying climatically disparate regions might help understand present-day landscapes. For example, Julius Büdel studied both cold-climate processes in Svalbard and weathering processes in tropical India to understand the origin of the relief of Central Europe, which he argued was a palimpsest of landforms formed at different times and under different climates.
The larger area is now additionally protected through Natura 2000, Special Protection Area (SPA) and Ramsar listings, and is part of the Norfolk Coast Area of Outstanding Natural Beauty. The first resident first "watcher" (warden) on Scolt Head was pioneering ornithologist and photographer Emma Turner. This isolated island has been largely undisturbed by human activity apart from service as an artillery range in World War II, and it is of international importance because of the extensive research into its geomorphology over nearly a century.
There are three EarthScope observatories, these include the San Andreas Fault Observatory at Depth (SAFOD), the Plate Boundary Observatory (PBO), and the Seismic and Magnetotelluric Observatory (USArray). These observatories consist of boreholes into an active fault zone, global positioning system (GPS) receivers, tiltmeters, long-baseline laser strainmeters, borehole strainmeters, permanent and portable seismographs, and magnetotelluric stations. The various EarthScope components will provide integrated and highly accessible data on geochronology and thermochronology, petrology and geochemistry, structure and tectonics, surficial processes and geomorphology, geodynamic modeling, rock physics, and hydrogeology.
Beavers are the prototypical ecosystem engineer because of the effects their dams have on channel flow, geomorphology, and ecology. Kelp are autogenic ecosystem engineers, by building the necessary structure for kelp forests An ecosystem engineer is any organism that creates, significantly modifies, maintains or destroys a habitat. These organisms can have a large impact on the species richness and landscape-level heterogeneity of an area. As a result, ecosystem engineers are important for maintaining the health and stability of the environment they are living in.
The flow spread to Porto Judeu, forming a coastal geomorphology of black basalt of large dimensions, arribas and coves of dangerous cliffs. As the lava, which was primarily aa and pahoehoe, flowed into these tubes slowly decreased, it left hollow caverns opening into galleries, some of various kilometres of length. It obtained its name from the great quantity of needle-like sedimentary deposited on the rocks and ceiling of the lava tube, ranging from . The gallery is situated over a smaller gallery that is wide.
Its implications prompted a myriad of research in various branches of physical geography. In the case of the Paleogeography, this theory provided a model for understanding the evolution of the landscape. For hydrology, glaciology, and climatology as a boost investigated as studying geographic factors shape the landscape and affect the cycle. The bulk of the work of William Morris Davis led to the development of a new branch of physical geography: Geomorphology whose contents until then did not differ from the rest of geography.
Throughout the years, Morisawa received many grants, following the successful geomorphic and geological research she produced. Organizations such as: The National Science Foundation, The US Department of Commerce Sea Grant Program, The United States Geological Survey, Ford Foundation, and The Office of Water Resources provided the funding Morisawa required to continue her research. In 2006 the Geological Society of America established the Marie Morisawa Award in her honor. The award is presented annually to a woman M.S. or Ph.D. graduate student pursuing a career in geomorphology.
Polymath figures such as the scientists and statesmen Shen Kuo (1031–1095) and Su Song (1020–1101) embodied advancements in all fields of study, including botany, zoology, geology, mineralogy, mechanics, magnetics, meteorology, horology, astronomy, pharmaceutical medicine, archeology, mathematics, cartography, optics, art criticism, hydraulics, and many other fields. Shen Kuo was the first to discern magnetic declination of true north while experimenting with a compass. Shen theorized that geographical climates gradually shifted over time. He created a theory of land formation involving concepts accepted in modern geomorphology.
When Sudestadas form, they bring long periods of precipitation, cloudy weather and cooler temperatures. These are common during the winter months. Because the Sudestada brings the highest wind speeds (particularly when these winds are combined with the astronomical tides), the Sudestada is responsible for floods that occur in low-lying areas. Its geomorphology along with inadequate drainage network and infrastructure, a flat landscape, and low elevations (much of Buenos Aires lies between above sea level) makes Buenos Aires highly vulnerable to flooding, particularly during heavy rainfall.
In 1913, he started his long association with the geology department of Birmingham University, joining as lecturer in Geology and Geomorphology, under Professor William Boulton. Birmingham University awarded him his PhD in 1920. In 1932, when Boulton retired, Jack Wills succeeded him as Professor and Head of Department, remaining in this post for seventeen years until his retirement in turn in 1949. He then became Professor Emeritus, retaining his link with the department until his death in 1979, a few weeks short of his ninety-sixth birthday.
Other factors of importance to the shape of the delta are the local tectonic activities of the Peel Boundary Fault, the substrate and geomorphology, as inherited from the Last Glacial and the coastal-marine dynamics, such as barrier and tidal inlet formations.Cohen et al. (2002) Since ~3000 yr BP (= years Before Present), human impact is seen in the delta. As a result of increasing land clearance (Bronze Age agriculture), in the upland areas (central Germany), the sediment load of the Rhine has strongly increasedHoffmann et al.
Terraced landscape, Goosenecks State Park, revealing the drop in river base level over time In geomorphology a river is said to be rejuvenated when it is eroding the landscape in response to a lowering of its base level. The process is often a result of a sudden fall in sea level or the rise of land. The disturbance enables a rise in the river's potential energy, increasing its riverbed erosion rate. The erosion occurs as a means for the river to adjust to its new base level.
When combined with the Aux Rochers River it gives a descent. The Port-Cartier-Sept-Îles Wildlife Sanctuary has developed trails along the river that lead from cottages to the Chute MacDonald. A walkway and gazebo allow accessibility and observation of the natural environment and the geomorphology of the area. MacDonald Falls and footbridge on the MacDonald River is one of the attractions of the Port-Cartier–Sept-Îles Wildlife Reserve, as are the Carlos Falls and the De la Montagne and MacDonald hiking trails.
The geomorphology of Port-Vendres meant that it developed in a different way from the nearby port of Collioure. Whereas Collioure has two beaches which slowly descend into a relatively shallow sandy-bottomed harbour, Port-Vendres is deeper and rockier. Collioure and Port-Vendres have therefore been used for different purposes - Collioure for small commercial ship and Port-Vendres for larger vessels and military transports. During the 20th century, this made it a main point of embarkation for French troops going to serve in Algeria.
The depiction of Titan's surface is speculation based on respectable scientific data that was available in 1997 – in fact the book "Lifting Titan's Veil"R. D. Lorenz and J. M. Mitton, Lifting Titan's Veil, Cambridge University Press, 2002 notes that Baxter's story paraphrases closely sections of papers by Lorenz on raindrops on Titan and the geomorphology of crater lakes. The Cassini probe's study of Titan, which began in 2005, has recently borne out that there do appear to be liquid lakes on the moon.
This may occur due to an equilibrium reached in the fluvial system resulting from: slowed or paused uplift, climate change, or a change in the bedrock type. Once downcutting continues the flattened valley bottom composed of bedrock (overlain with a possible thin layer of alluvium) is left above either a stream or river channel. These bedrock terraces are the strath terraces and are erosional in nature.Burbank, D.W., and R.S. Anderson, Robert, 2001, Tectonic Geomorphology, Malden, MA: Blackwell Publishing Unpaired fluvial terraces on the South Fork of the Shoshone River, Park County, Wyoming, 1923.
He was later awarded a Doctor of Science degree from the University of Oxford on the basis of his research linking concepts in geomorphology with quantitative measurements in engineering geology. Selby took part in either three or four field expeditions to Antarctica, including in 1968–69, 1971–72, and 1978–79. On the first of these, he became the first geomorphologist to travel to Antarctica. The 1978–79 trip to the Britannia Range–Darwin Glacier region was led by Selby, and mapped exposures in the McCraw Glacier area, and discovered iron meteorites on Derrick Peak.
Sam Farr and Senator Bruce McPherson, the Fish and Game retreated from preventing the council from filling the dam, but stipulated that certain regulations must be adhered to. The National Marine Fisheries Service discovered shortly afterward that the Council appeared to have filled the dam in violation of these regulations, "dewatering" the river below the dam and killing at least 30 threatened steelhead trout. The council could have been subject to fines of up to $360,000. The council avoided paying a fine by building a $1 million custom fish ladder designed by Swanson Hydrology + Geomorphology.
R.B. Salama, D.W. Pollock, J.D. Byrne and G.W. Bartle. 2000. Geomorphology, Soils and Landuse in the Swan Coastal Plain in relation to Contaminant Leaching, Agrochemical Pollution of Water Resources, Proceedings of a Conference held on 16–18 February 2000 at Hat Yai, Thailand, Australian Centre for International Agricultural Research, Canberra 2001, pp. 105-117. More recently, later authors have argued that these sandplains are mostly the product of in situ weathering. The carbonate material of all three dune systems has been completely leached, leaving dunes which consist solely of quartz sand.
Thus, it is this scientist's name that we should associate with the discovery and correct genetic interpretation of the relief of giant current ripples. After Pardee's publication in 1942, giant current ripples have been found practically everywhere on the territory of the basaltic Columbia Plateau (this was the direction of the cataclysmic outbursts of Missoula and other ice-dammed lakes). A special study of the geomorphology and palaeohydrology of the American scabland was begun by Victor Baker.Baker, V. R. Paleohydrology and sedimentology of Lake Missoula Flooding in Eastern Washington, Gel. Soc.
Lameo irrigation and sedimentation at Capinota cover 228 ha and more than 200 farmers participate in it. It enables the farmers to practise an intensive and market oriented agriculture where mainly potatoes and Dutch tomatoes are grown. In fields located further away from the river, the soil is enriched by mixing the river sediments with the existing soil, adding chicken manure. From studies of geomorphology and sedimentation in the Valle Alto region it can be estimated that the technique of lameo goes back as far as 1500 BCE.
The department's volcanoes and its geomorphology make its geography remarkable. It is formed by upstream portion of the Tambo River, one of the most torrential coastal rivers, which forms deep valleys that can be divided into three sectors, the first one being in the northwest, forming the Puquina- La Capilla sector. These are veritable oasis enclaved in the rocks; arid hillsides and some terraces where horticulture is possible. High quality alfalfa as well as fruits, especially grapes, are produced here, due to a good climate and a rich soil.
This is a list of rock formations in New Zealand based on their aesthetic and cultural importance. New Zealand's geomorphology is formed through an interaction between uplift, erosion and the underlying rock type. Most of the notable examples listed here are formed by selective erosion, for example waves and rivers can more easily erode sandstone than basalt and can also exploit joints or faults in the rock-mass. Some rocks like limestone (Waitomo Caves) and marble (Takaka Hill) can also be dissolved in water which forms a distinctive karst geomorpholohy.
Under its jurisdiction are: the Bielany-Tyniec Landscape Park (Park Bielańsko-Tyniecki), Tenczynek Landscape Park (Park Tencziński) and Kraków Valleys Landscape Park (Park Krajobrazowy Dolinki Krakowskie), with their watersheds. All natural reserves of the Polish Jura Chain are part of the CORINE biotopes programme due to their unique flora, fauna, geomorphology and landscape. The western part of Kraków constitutes the so-called Obszar Krakowski ecological network, including the ecological corridor of the Vistula river. The southern slopes of limestone hills provide conditions for the development of thermophilous vegetation, grasslands and scrubs.
Remote sensing data are often validated by ground truth, which usually serves as training data in image classification to ensure quality. The image interpretation could be achieved by an interpreter or computation. The reliability of the map interpreted is high only if the expert has a thorough understanding of geomorphology, how the surface landscape could be shaped by possible interactions of numerous factors and the limitation of the method. Although there exist a wealth of experiences is present for visual interpretation of aerial photos, the method is time-consuming and prone to human errors.
The American Quaternary Association (AMQUA) is a professional organization of North American scientists devoted to studies of the quaternary geological period. They were founded in 1970 and their stated goals are to "foster cooperation and communication among the remarkably broad array of disciplines involved in studying the Quaternary Period". These disciplines include: anthropology, archaeology, botany, climatology, ecology, geochemistry, geochronology, geography, geology, geomorphology, geophysics, hydrology, limnology, meteorology, neotectonics, oceanography, paleontology, palynology, soil science, and zoology. They host biennial conventions on a variety of themes, with themes chosen to appeal to a broad range of represented disciplines.
Footpath across Fron-dêg Flat on Esclusham Mountain The underlying rocks are a Carboniferous Limestone along with some Millstone Grit to the east.Sparks, B. Geomorphology, Longman, 1972, p.174 The area was rich in minerals, particularly lead and zinc deposits. The South Minera Vein, a fault fissure rilled with mineral matter, ran through the area of Esclusham Mountain and, until the second decade of the 20th century, there were many lead mines in the area, some of whose levels joined with the substantial system of natural caves beneath the mountain.
Though she was primarily a petrologist, she made astute observations concerning inequalities in erosion in catchments and hence the survival of palaeoforms in the landscape. Although these observations were opposed to one of primary principles of geomorphology at the time, Knopf implied that remnant landforms should still survive for an extended period due to unequal erosion. In 1951, she joined Stanford University in geology department as a research associate. She continued to study the Stissing Mountain rocks until her retirement in 1955 but also made some expeditions to the Rocky Mountains.
Geological Society of America, 1988. Surface of the Earth, showing higher elevations in red. Geomorphology (from Ancient Greek: γῆ, gê, "earth"; μορφή, morphḗ, "form"; and λόγος, lógos, "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling.
1985 John Edward Marr in his The Scientific Study of SceneryMarr, J.E. The Scientific Study of Scenery. Methuen, page iii, 1900. considered his book as, 'an Introductory Treatise on Geomorphology, a subject which has sprung from the union of Geology and Geography'. An early popular geomorphic model was the geographical cycle or cycle of erosion model of broad-scale landscape evolution developed by William Morris Davis between 1884 and 1899. It was an elaboration of the uniformitarianism theory that had first been proposed by James Hutton (1726–1797).
Both volcanic (eruptive) and plutonic (intrusive) igneous processes can have important impacts on geomorphology. The action of volcanoes tends to rejuvenize landscapes, covering the old land surface with lava and tephra, releasing pyroclastic material and forcing rivers through new paths. The cones built by eruptions also build substantial new topography, which can be acted upon by other surface processes. Plutonic rocks intruding then solidifying at depth can cause both uplift or subsidence of the surface, depending on whether the new material is denser or less dense than the rock it displaces.
Tectonic effects on geomorphology can range from scales of millions of years to minutes or less. The effects of tectonics on landscape are heavily dependent on the nature of the underlying bedrock fabric that more or less controls what kind of local morphology tectonics can shape. Earthquakes can, in terms of minutes, submerge large areas of land creating new wetlands. Isostatic rebound can account for significant changes over hundreds to thousands of years, and allows erosion of a mountain belt to promote further erosion as mass is removed from the chain and the belt uplifts.
In 1984, Pitman was awarded the Society for Sedimentary Geology’s Francis Shepard Medal. In 1996, he was awarded the Maurice Ewing Medal by the American Geophysical Union. In 1998, he received the Alexander Agassiz Medal of the United States National Academy of Sciences "for his fundamental contribution to the plate tectonic revolution through insightful analysis of marine magnetic anomalies and for his studies of the causes and effects of sea-level changes". In 2000, he was awarded the Vetlesen Prize for plate tectonic theory, theoretical geomorphology and tectonics.
Loe Bar The beach from Porthleven to Gunwalloe is important for coastal geomorphology as it is formed by a barrier beach moving onshore during the Holocene and maintained by a predominantly south-west wave regime. During storms the Bar can be overrun by the sea forming a series of washover fans resulting in, annual laminated sediments, which are unique in Great Britain. The habitat is unique in Cornwall with rare species of plants, bryophytes, algae and insects. It is also an important overwintering site for nearly eighty species of birds and up to 1,200 wildfowl.
He published several papers on geomorphology, which is in the field, one of their first looks. The versatility of curious Octávio Barbosa is that, from 1952 to 1958, he published some work on paleobotany, setting the age of Gondwana floras and weaving observations (in 1957) on theParatoxopitys Americana, a fossil wood of Irati Formation. Had the opportunity to spend some time on his passion: the diamonds. Since 1938, when he studied the diamond "Minas Gerais", by Coromandel, it remained latent interest to academics, studying, still in Prospec, diamonds in western Minas Gerais.
Since the island's capital was moved from Paphos to Nicosia after the Roman times, transportation to Paphos - being a very small town at the time - from the rest of the island was very difficult due to the mountainous geomorphology of the island's Southwestern coast. Until the British colonial times people also used the sea as an alternative to avoid the extremely long dangerous path connecting the two areas. In the early 20th Century the first road was built. It was approximately 80 km long and not more than 3m wide.
Generally, predictive modelling in archaeology is establishing statistically valid causal or covariable relationships between natural proxies such as soil types, elevation, slope, vegetation, proximity to water, geology, geomorphology, etc., and the presence of archaeological features. Through analysis of these quantifiable attributes from land that has undergone archaeological survey, sometimes the "archaeological sensitivity" of unsurveyed areas can be anticipated based on the natural proxies in those areas. Large land managers in the United States, such as the Bureau of Land Management (BLM), the Department of Defense (DOD),Heidelberg, Kurt, et al.
Cross sectional area of a trapezoidal open channel, red highlights wetted perimeter Change of wetted perimeter (blue) of trapezoidal canal as a function of angle ψ. The wetted perimeter is the perimeter of the cross sectional area that is "wet". The length of line of the intersection of channel wetted surface with a cross sectional plane normal to the flow direction. The term wetted perimeter is common in civil engineering, environmental engineering, hydrology, geomorphology, and heat transfer applications; it is associated with the hydraulic diameter or hydraulic radius.
Anto Raukos, "Evolution of the theory of continental glaciation in northern and eastern Europe" in R. H. Grapes, D. R. Oldroyd, A. Grigelis (eds), History of Geomorphology and Quaternary Geology, pp. 79-86, Geological Society of London, 2008 . The Estonian boulders were important in the development of the idea that northern Europe was once covered in glaciers. The first to suggest that the boulders were moved by glaciers was Russian mineralogist Vasily Severgin who was led to this conclusion by their similarity to Finnish basement rock at the very early date of 1815.
The mean depth of the lagoon is 4.5 m, but in the central navigation channel it can be 10 m deep. Near Bouzigues there is a 100-metre diameter depression of 30 metres. This 'Fosse de la Vise' is the source of a hot spring that feeds the spa in Balaruc. Its size and depth, which distinguish it from other lagoons of the region, is explained by the geomorphology of the region: it is the syncline formed from folding which produced the corresponding anticline of the Gardiole in the north east.
He graduated in 1953 having won the Philip Lake Prize. His doctoral thesis in 1956 was on the glacial landforms of north Wales.Oxford Dictionary of National Biography His research on glaciation in Wales and Norway led to the publication of a classic text on the subject, 'Geomorphology, Glacial and Periglacial' with Cuchlaine King, published by Hodder & Stoughton in May 1968, which was later substantially revised in 1975. He became a lecturer and then senior lecturer at Birkbeck College, London and University College, London and became a professor at King's College, London in 1982.
She was recognized as a distinguished lecturer, and then was promoted to associate professor in 1970. In this position, she taught geology, environmental education, landscapes and resources of Alaska, geomorphology, and paleontology, in addition to doing other work expected of a professor including student advising and curriculum development. She worked for UAA for 25 years until her retirement from teaching in 1984. In 1964, she and four others were in the middle of the frozen-over Portage Lake boring holes in the ice to gather sampling data when the Great Alaska earthquake struck.
A fire destroyed the wood attic and third floor and in 1956 the building was remodeled including a new fourth floor. The modern facilities were available to support research in many areas including geochemistry; stable-isotope geochemistry; geochronology; paleomagnetics; seismology and high resolution geophysics; aquatic and ecosystems ecology; GIS and quantitative geomorphology; and water quality. The building was rededicated in the fall of 2015, after a period of renovations, and now houses offices from Student Affairs and academic departments including modern language and literature, religion studies, sociology, anthropology.
It was part of the history of inland exploration (Burke and Wills expedition) and of the development of the pastoral industry in western New South Wales. The place is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in New South Wales. The area contains a relict lake system whose sediments, geomorphology and soils contain an outstanding record of low-altitude, non-glaciated Pleistocene landscape. The area contains outstanding examples of lunettes including Chibnalwood Lunette, the largest clay lunette in the world.
Some of the samples were collected by Rubin in collaboration with other geologists such as J Harlen Bretz (who was Rubin's Geomorphology professor at UChicago), Carl Leland Horberg, William John Wayne, Richard Parker Goldthwait, James Zumberge, and Donald Eschman. Samples were collected by other collectors as well. Flint and Rubin published a brief assessment of the stratigraphic meaning of these samples and their age determinations in May 1955. One of the conclusions was that a major glaciation began 25,000 or more years ago and reached a maximum about 20,000 years ago.
Larsen's master's thesis is titled Development and Testing of a Coupled Heat and Moisture Transfer Model to Assess Subsurface Moisture Gradients and was completed in 2003. Larsen moved on to the University of Colorado-Boulder at age 21 and began her doctoral studies in the Civil, Environmental, and Architectural Engineering department. At the University of Colorado, Larsen studied fluvial geomorphology, aquatic ecology, and fluid mechanics. She began researching the Florida Everglades and how they evolved to create the unique slough and ridge landscape that is essential to the Everglades ecosystem.
Larsen was hired at the University of California, Berkeley as an Assistant professor for the Department of Geography in 2013. In 2018, she was made an Associate professor for the Geography and Civil and Environmental engineering department at the University of California, Berkeley and currently holds this position. Larsen's research focuses on the fields of hydrology, geomorphology, environmental fluid mechanics, complex systems, environmental modeling, aquatic ecology, restoration ecology, wetlands, sediment transport. She is most known for her achievements in research on the Florida Everglades which have influenced numerous restoration efforts in the area.
Geomorphology in the area is a product of recent glaciation and post-glacial erosion. The last, or Fraser, glaciation began 33,500 years ago and reached its peak 17,500 years ago. Ice retreat was delayed several thousand years by glaciers grounding, with several minor readvances. Glacial marine sedimentation (mud with stones dropped from icebergs) is believed to have ceased by 10,600 yr BP. The weight of ice had depressed the land surface, so during deglaciation, the sea flooded the land up to 220 m higher than it is today.
It is obvious today that the journeys of the two explorers were partly influenced or disrupted by world politics and by newly industrialized society. During their travels, they conducted numerous observations and provided documentation later used for works in geomorphology, climatology, and ethnography. Their initial intention was to enrich their lives and the world with new knowledge and understanding. In their diaries, they described the areas they passed through, discussed Indian tribes they met, and left numerous sketches, photographs, maps, data, and memories regarding the nature and cultures that they had so much enjoyed meeting.
The geology and geomorphology of the islands is varied. Some, such as Skye and Mull are mountainous, while others like Tiree and Sanday are relatively low lying. Many have bedrock made from ancient Archaean Lewisian Gneiss which was formed 3 billion years ago; Shapinsay and other Orkney islands are formed from Old Red Sandstone, which is 400 million years old; and others such as Rùm from more recent Tertiary volcanoes.McKirdy, Alan Gordon, John & Crofts, Roger (2007) Land of Mountain and Flood: The Geology and Landforms of Scotland. Edinburgh. Birlinn.
Folds in rock as investigated by Cadell Dr Henry Moubray Cadell of Grange, DL FRSE LLD (1860 – 10 April 1934) was a Scottish geologist and geographer, noted for his work on the Moine Thrust, the oil-shale fields of West Lothian, and his experiments in mountain building published in 1888. He also travelled extensively abroad, for example in 1899 he travelled the length of the Irrawaddy River in Burma. He is especially remembered for his working models, explaining geomorphology, the science relating to the folding of rock beds. He was also a competent amateur artist.

He is the author of a number of articles and 90 books, including university texts, walking guides, coffee table glossies, and books of popular science. His Glaciers and Landscape (written with David Sugden), a university textbook, remained in print as a geomorphology classic for almost 30 years. He also writes on topics of local interest related to Wales: tourist guides, books of local jokes, walkers' handbooks, and titles on local folklore and traditions. In 2012 he won the Wishing Shelf Book award for his children's book called The Strange Affair of the Ethiopian Treasure Chest.
Emeritus Professor Andrew Shaw Goudie (born 21 August 1945 in Cheltenham) is a geographer at the University of Oxford specialising in desert geomorphology, dust storms, weathering, and climatic change in the tropics. He is also known for his teaching and best-selling textbooks on human impacts on the environment. He is the author, co-author, editor, or co-editor of forty-one books (many of which have appeared in numerous editions) and more than two hundred papers published in learned journals. He combines research and some teaching with administrative roles.
Since the 1920s more and more works have emerged in which individual regions have been archaeologically researched. At the same time, more emphasis was placed on investigating the settlements themselves. Researchers such as Gerhard Bersu, Hermann Stoll, and Robert Rudolf Schmidt, who worked mainly in southern Germany, were among this pioneering phase of modern settlement archeology. The excavations at the Federsee, for example, involved the natural sciences at an early stage (pollen analysis (Palynology), moor geology and geomorphology, dendrochronology, radiocarbon dating, archaeozoology and archaeobotany, paleoclimatology, material research, etc.).
Despite its elevation of , Glacier Peak is a small stratovolcano. Its relatively high summit is a consequence of its location atop a high ridge, but its volcanic portion extends only above the underlying ridge. Another Cascade Arc volcano with similar geomorphology is the Mount Meager massif in southwestern British Columbia, Canada, which is situated on a ridge of nonvolcanic, crystalline and metamorphic rock. View from Liberty Cap across the Suiattle River Valley Of the five major volcanoes in Washington, only Glacier Peak and Mount St. Helens have had large eruptions in the past 15,000 years.
Seismically active faults and related fault generated folds have a direct effect on the geomorphology of a region. This may allow the direct identification of active structures not previously known. In some cases such observations can be used quantitatively to constrain the repeat period of major earthquakes, such as the raised beaches of Turakirae Head recording the history of coseismic uplift of the Rimutaka Range due to displacement on the Wairarapa Fault in North Island, New Zealand.McSaveney, M.J., Graham, I.J., Begg, J.G., Beu, A.G., Hull, A.G., Kyeong, K. & Zondervan, A. 2006.
All motorways are named by using the capital letter "A", followed by a number (e.g. A1). The main motorways of Greece have a single digit number and auxiliary motorways perpendicular to the main ones have a double digit number (e.g. A25). Motorways have their own white-on-green signs, while National Roads are designated by white-on-blue signs. The construction of the Greek motorway network has been, to a large extent, a very complex and demanding project due to the peculiarities of the geomorphology of the areas through which the new roads pass.
She knew that John would either know himself what the feature was, or know whom to ask about the feature. Catherine also reached out to BC Parks and her local Clearwater contacts to organize the reconnaissance work. John and Catherine co-wrote the permit application (for exploration) and John sought additional support from the caving community – he brought in Lee Hollis and Chas Yonge. At the cave site exploration in September 2018, Catherine evaluated the geology and geomorphology of the site in an effort to understand more about the cave's formation and its age.
The Meerdaal Free Wood on a late sixteenth century map Meerdaal, also known as Meerdaalwoud and Meerdaalbos, is a woodland lying east of Brussels and south of Leuven, on the loess plateau of Brabant in central Belgium. The bigger part of it has most likely been continuously forested since the Middle Ages, but the archaeological record and geomorphology give evidence of a profound human influence, probably including agriculture, during the Roman era and the Iron Age.Vanwalleghem, Tom et alii. Prehistoric and Roman gullying in the European loess belt: a case study from central Belgium.
Each ecological vegetation class is described through a combination of its floristic, life-form, and reproductive strategy profiles, and through an inferred fidelity to particular environmental attributes. Although there are more than 300 individual EVCs, some can be grouped together to form a bioregion, which is a geographical approach to classifying the environment using a climate, geomorphology, geology, soils and vegetation. There are 28 bioregions across Victoria. Each EVC within a biogregion can be assigned a conservation status , to indicate its degree of alteration since European settlement in Australia.
The geology and geomorphology of the area is characterised by an island of outcropping bedrock on the eastern headland and joined to other bedrock outcrops on its western end by a sand spit which forms the main part of the headland. The Peninsula still has quite a view overlapping transgressive barrier dunes and it is believed that they have shifted north from Bate Bay. Older stable parabolic dunes occur on a series of north to south oriented ridges and while most of the vegetation has been cleared, some dry sclerophyll woodland remains.
The geomorphology of China can be divided into several parts. The historical centre of Chinese culture is on the loess plateau, the world's largest Quaternary loess deposit, and on the alluvial lands at the east of it. The alluvial East China plain extends from just south of Beijing in the north, to the Yangtze river delta in the south, punctuated only by the igneous Shandong highlands and peninsula. South of the Yangtze river, most of the landscape is mountainous, dominated by sedimentary deposits and by the South China Craton.
At the southern pole, a small cap of CO2 ice remains during summer, but this cap too is underlain by water ice. The final piece of the Martian climate puzzle was provided by Mariner 4 in 1965. Grainy television pictures from the spacecraft showed a surface dominated by impact craters, which implied that the surface was very old and had not experienced the level of erosion and tectonic activity seen on Earth. Little erosion meant that liquid water had probably not played a large role in the planet's geomorphology for billions of years.
Fajã de São João Fajã de Santo Cristo The geomorphology of the island (its high cliffs, rough central plateaus and scattered fajãs) resulted in the concentration of human settlements along the coast. Historically these communities were linked by coastal ports since the trails in the interior were barely transitable. Consequently, communities were isolated from one another necessitating local solutions to common problems and building local ties between families. Velas, Calheta and Topo developed partially due to well developed ports and local economies, in addition to administrative necessity and central positions.
There had been some ideas on cyclical erosion in the Graeco- Roman world and then in the Islamic world and Europe during the Middle Ages. However the immediate influences of William Morris Davis, the creator of the cycle of erosion model, were 19th century American explorers. The end of the American Civil War (1861–1865) led to a resumption of the exploration of the western United States. Three explorers, John Wesley Powell, Clarence Edward Dutton and Grove Karl Gilbert, wrote about the geomorphology and geology in the landscapes they encountered.
The terrain is quite varied and is thus divided into several areas based on geomorphology. The mountainous and most recent part of the island can be found to the west, the centre of which is dominated by Mount Capanne (), also called the "roof of the Tuscan Archipelago". The mountain is home to many animal species including the mouflon and wild boar, two species that flourish despite the continuous influx of tourists. The central part of the island is a mostly flat section with the width being reduced to just four kilometres ().
The station is named for Henryk Arctowski (1871-1959), who as meteorologist had accompanied the Belgian explorer Baron Adrien de Gerlache on the Belgian Antarctic Expedition "Belgica", 1897-1899. This was the first expedition to overwinter in Antarctica. He proposed the original notion of a wind chill factor, arguing that wind could be as damaging to human flesh as cold in harsh climates. Established on 26 February 1977, the station is managed by the Polish Academy of Sciences; its main research areas include marine biology, oceanography, geology, geomorphology, glaciology, meteorology, climatology, seismology, magnetism and ecology.
The town is located in the northeast of the Salento plains, not far from the Itria Valley. The geomorphology of the land is flat, slightly undulating on the border with the municipalities of Carovigno and Ostuni. It is located from the Adriatic coast, the port nearest beach Specchiolla, a historic marine residence of San Vito. San Vito also is from the Torre Guaceto, located in Serranova, a nature reserve, accessible by foot or bicycle (Pennagrossa Point), and from the tower which gives its name to the protected area.
A tessellated pavement at Eaglehawk Neck, Australia, where a rock surface has been divided by fractures, producing a set of rectangular blocks In geology and geomorphology, a tessellated pavement is a relatively flat rock surface that is subdivided into more or less regular rectangles, blocks approaching rectangles, or irregular or regular polygons by fractures, frequently systematic joints, within the rock. This type of rock pavement bears this name because it is fractured into polygonal blocks that resemble tiles of a mosaic floor, or tessellations.Branagan, D.F. (1983) Tesselated pavements. In R.W. Young and G.C. Nanson, eds.
This type of tessellated pavement is commonly observed along shorelines where wave action has created relatively flat and extensive wave- cut platforms that expose jointed bedrock and keeps the surfaces of these platforms relatively clear of debris.Banks, M.R., E.A. Colhoun, R.J. Ford, and E. Williams (1986) A reconnaissance geology and geomorphology of Tasman Peninsula. In S.J. Smith, ed., pp. 7–24, Papers and Proceedings of the Royal Society of Tasmania, Tasman Peninsula : A symposium conducted by the Royal Society of Tasmania at Port Arthur, Tasmania, November 1–3.
This was made possible through funding from the National Science Foundation (NSF). From 1977 through 1993, the Laboratory emphasized the integration of education and basic and applied research. Several new faculty were appointed to bring new research efforts to SAFL like computational fluid dynamics, water resources and energy, environmental water research, naval hydrodynamics, cavitation, wind engineering, small hydropower development, rainfall modeling, and geomorphology to name a few. The NSF made SAFL the headquarters of the National Center of Earth-Surface Dynamics (NCED) in 2002, a center devoted to greater predictive earth surface technology and research.
Paradise grew up in North Beach and Telegraph Hill, San Francisco. He obtained his BS in geosciences and mining in 1979 from the Mackay School of Mines (part of the University of Nevada). After graduation, he spent a year, in 1980, with the Gemological Institute of America, and in 1983 he worked with the Gemological Institute in London. In 1990 he completed his MS in physical geography and cartography at Georgia State University, and in 1993 he obtained his PhD in geomorphology and cultural heritage management from Arizona State University.
In terms of geomorphology and seismicity, Tyre is close to the Roum Fault and the Yammouneh Fault. Though it has suffered a number of devastating Earthquakes over the millennia, the threat level is considered to be low in most places and moderate in a few others. However, a tsunami following an earthquake and subsequent landslides and floods pose major natural risks to the Tyrian population. Vast reserves of natural gas are estimated to lie beneath Lebanese waters, much of it off Tyre's coast, but exploitation has been delayed by border disputes with Israel.
He believed these to include drainage density, channel slope, overland flow length, and other less important factors. However, late in his career, he began to advocate a very different mechanism of "hydrophysical" geomorphology, which he believed better explained his prior observations. Horton detailed his theory in a landmark paper published in 1945, only a month before his death, in the Bulletin of the Geological Society of America. He summarized his conclusions with four laws: the law of stream numbers, the law of stream lengths, the limits of infiltration capacity, and the runoff-detention-storage relation.
Koba Kharadze, The unrivalled authority on nature study: Levan Maruashvili, Tbilisi, 2012. In 1952 after defending his Doctor's degree on the subject "South-Georgian volcanic upland (structure, relief, historical development)" he made a great contribution to the study of volcanic areas of Alpine-Mediterranean belt, which has not lost its significance up till now. In 1953, he began working at the Vakhushti Bagrationi Institute of Geography, Georgian Academy of Sciences. At first he headed the department of Physical Geography and from then onwards the Departments of Geomorphology and Paleogeography until his death.
The reason that academicians have not designated the gigantic settlements of Cucuteni-Trypillia culture as "cities", is due to the lack of conclusive evidence for internal social differentiation or specialization. However, there is some debate among scholars whether these settlements ought to be labeled as proto-cities. The Cucuteni-Trypillia settlements were usually located on a place where the geomorphology provided natural barriers to protect the site: most notably using high river terraces or canyon edges. The natural barriers were supplemented with fences, earthworks and ditches, or even more elaborate wooden and clay ramparts.
The presence of hard rock protrusions created in the landscape, known as the amphibolites of Sulåive. In addition, the orientation of geological cause slopes east (to the right of the image) significantly more steep while the western slopes are gentler slopes . While the Scandinavian Alps gradually increase altitude, erosion can negate this slow growth. While this includes river erosion, the glacial erosion, especially during the great glaciations of the Quaternary (from 1.5 Ma) has had the most influence on the current geomorphology of the chain and the reserve.
The unusual geomorphology of the Tsingy de Bemaraha World Heritage Site, which encompasses both the National Park and the adjacent Strict Nature Reserve, means that the Site is home to an exceptionally large number of endemic species of plants and animalsGriffiths, O.L. & Herbert, D.G. 2013.

Transport is also caused by glaciers as they flow, and on terrestrial surfaces under the influence of wind. Sediment transport due only to gravity can occur on sloping surfaces in general, including hillslopes, scarps, cliffs, and the continental shelf—continental slope boundary. Sediment transport is important in the fields of sedimentary geology, geomorphology, civil engineering and environmental engineering (see applications, below). Knowledge of sediment transport is most often used to determine whether erosion or deposition will occur, the magnitude of this erosion or deposition, and the time and distance over which it will occur.
As soil starts to slowly form, new plant species colonize the stable dunes ultimately developing more extensive root structures and plant diversity. When the dune has become continuously vegetated, lichen and moss grows in the understory, providing a water-repellent surface that reduces erosion (through rainfall and wind), this results in the official formation of the grey dune. Pluvial processes dominate the geomorphology of grey dunes, with rain splash and slope wash being the most common processes taking place. Erosion can take place in the form of rain splash and slope wash.
Lester Charles King (1907–1989) was an English geologist and geomorphologist known for his theories on scarp retreat. He offered a very different view of the origin of continental landscaping than that of William Morris Davis. Studying at university in New Zealand King was a disciple of Charles Cotton who was heavily influenced by Davis. While King's ideas were an attempt at refuting Davis' cycle of erosion they were themselves of cyclical nature and contributed to what Cliff Ollier has called "Davis bashing" — the ridicule of cyclical theories in geomorphology, in particular Davis' ones.
In geomorphology, cryoplanation or altiplanation is a term used to both describe and explain the formation of plains, terraces and pediments in periglacial environments. Uncertainty surrounds the term, and the effectiveness of the cryoplanation process is held to be limited meaning it can only produce small terraces. Instead, many of so-called cryoplanation terraces are likely an expression of the underlying lithology and rock structure rather than being unique products of cold-climate processes. Cryoplanation can be seen as a variant of pediplanation that is restricted to cold climates.
However, ice-dammed lakes and isostatic rebound in the region played an important role in geomorphology for several more millennia. The Baltic Ice Lake gave way to the Yoldia Sea, Ancylus Lake and Littorina Sea, followed by the Limnea Sea. The land of Estonia rose 65 meters in a span of only 2450 years and has risen an additional 50 meters in the past 10,000 years. Deglaciation led to the formation of river valleys and 20 to 40 percent of downcutting in rivers in the south happened during a short span after glaciation.
The research station was built by the Soviet Antarctic Expedition in 1956 and named Oazis (Оазис, ). The station was handed over by the Soviet Academy of Sciences to the Polish Academy of Sciences in January 1959. It was manned briefly by the Polish expedition, which carried out a number of studies, primarily in the fields of gravimetry and geomorphology. The station has not been used regularly since, due to the lack of funds and the high costs of air transport, and there are no plans to reopen the station as a permanent institution.
Cvijić did his first (and most important) field research in eastern Serbia, observing the structure of the Kučaj mountains and Prekonoska Cave in his PhD thesis (accepted in Vienna on 22 January 1893). Ethnographic map of the Balkans, co- authored by Cvijić He was interested in geology and geomorphology. Cvijić's monograph on lime karst was well received in European scientific circles, and an introductory academic lecture established him as the first South Slavic tectonicist. The Serbian lime fields had been studied only peripherally by Otto von Pirch (1830), Ami Boué (1840), Felix Philipp Kanitz, Milan Milićević, Jovan Žujović and Vladimir Karić before him.
Specimens of this species were collected in 1972 and 1973 by Irish botanist Ernest Charles Nelson, from the vicinity of Quoin Head in the Fitzgerald River National Park on the south coast of Western Australia. Nelson published the species in 1978, as part of a comprehensive taxonomic revision of the genus. He chose the specific epithet dobagii from the initials of the Department of Biogeography and Geomorphology, the Australian National University department at which Nelson had performed the work underpinning the publication. Nelson followed George Bentham in dividing Adenanthos into two sections, placing A. dobagii into A. sect.

James W. Kirchner is professor of Earth and Planetary Science at University of California, Berkeley. His current research spans the fields of geomorphology, hydrology, environmental geochemistry, evolutionary ecology, and paleobiology. He currently serves as the director of Berkeley's Central Sierra Field Research Stations."Keck funds project to track life cycle of water"; Sanders, Robert, Media Relations; February 23, 2006; Retrieved on 2007-01-19 A study by Kirchner and Anne Weil showed that the time taken for life on earth to recover from extinction episodes such as that which destroyed the dinosaurs is not, as previously thought, proportional to the damage done.
Shen Kuo (沈括) (1031-1095)) The medieval Chinese Song Dynasty statesman and scientist Shen Kuo (1031-1095 AD) wrote of his land formation theory involving concepts of mineralogy. In his Meng Xi Bi Tan (梦溪笔谈; Dream Pool Essays, 1088), Shen formulated a hypothesis for the process of land formation (geomorphology); based on his observation of marine fossil shells in a geological stratum in the Taihang Mountains hundreds of miles from the Pacific Ocean.Sivin, III, 23. He inferred that the land was formed by erosion of the mountains and by deposition of silt, and described soil erosion, sedimentation and uplift.
Seven main rivers and innumerable watercourses form a network of channels at this estuarine delta. All the rivers have a southward course towards the sea. The eco- geography of this area is totally dependent on the tidal effect of two flow tides and two ebb tides occurring within 24 hours with a tidal range of 3–5 m and up to 8 m in normal spring tide, inundating the whole of Sundarban in varying depths. The tidal action deposits silts back on the channels and raising the bed, it forms new islands and creeks contributing to uncertain geomorphology.
In geomorphology, an outburst flood — a type of megaflood — is a high- magnitude, low-frequency catastrophic flood involving the sudden release of a large quantity of water. During the last deglaciation, numerous glacial lake outburst floods were caused by the collapse of either ice sheets or glaciers that formed the dams of proglacial lakes. Examples of older outburst floods are known from the geological past of the Earth and inferred from geomorphological evidence on Mars. Landslides, lahars, and volcanic dams can also block rivers and create lakes, which trigger such floods when the rock or earthen barrier collapses or is eroded.
Dr. Tomlinson was a native of Newmarket (England) and prior to attending university, he served in the Royal Air Force from 1951–1954 as a pilot and flying officer. After his military service, Dr. Tomlinson attended the University of Nottingham and Acadia University for two separate undergraduate degrees in geography and geology, respectively. He received a master's degree in geography from McGill University where he specialised in the glacial geomorphology of Labrador. His Doctoral thesis at University College London was titled: The application of electronic computing methods and techniques to the storage, compilation, and assessment of mapped data.
The Louisiana Geological Survey is a state geological survey established by the Louisiana legislature by Act 131 in 1934 to serve the citizens Louisiana by collecting, preserving, and disseminating impartial information on the geomorphology, hydrogeology, geology, paleontology, economic geology, and geological resources of Louisiana. The Louisiana Geological Survey was originally part of the Louisiana Department of Conservation. Later it was a division of the Louisiana Department of Natural Resources and finally transferred by the Louisiana legislature's HB 2353 to Louisiana State University. At Louisiana State University, it is part of the Office of Research and Economic Development.
With regard to valley forms, for example, uniformitarianism posited a sequence in which a river runs through a flat terrain, gradually carving an increasingly deep valley, until the side valleys eventually erode, flattening the terrain again, though at a lower elevation. It was thought that tectonic uplift could then start the cycle over. In the decades following Davis's development of this idea, many of those studying geomorphology sought to fit their findings into this framework, known today as "Davisian". Davis's ideas are of historical importance, but have been largely superseded today, mainly due to their lack of predictive power and qualitative nature.
Wooden trail through nature park Kopački Rit in Osijek-Baranja County Croatia can be subdivided between a number of ecoregions because of its climate and geomorphology. The country is consequently one of the richest in Europe in terms of biodiversity. There are four types of biogeographical regions in Croatia—Mediterranean along the coast and in its immediate hinterland, Alpine in most of Lika and Gorski Kotar, Pannonian along Drava and Danube, and Continental in the remaining areas. One of the most significant are karst habitats which include submerged karst, such as Zrmanja and Krka canyons and tufa barriers, as well as underground habitats.
Using evidence from earthquakes, remote sensing, geodesy and geomorphology he is able to observe, quantitatively, the geometry and rates of deformation processes while they are active. In addition to seismology, his current research uses space-based remote sensing (including radar interferometry, GPS measurements and optical imagery) combined with observations of the landscape in the field, to study the evolution and deformation of the continents on all scales, from the movement of individual faults in earthquakes to the evolution of mountain belts. Much of his work is carried out in collaboration with researchers from the COMET ProjectCOMET Project where he is Associate Director.
Marjorie Mary Sweeting (28 February 1920 - 31 December 1994 in Oxford), was a British geomorphologist specialising in karst phenomena. Sweeting had gained extensive knowledge on various typographies by travelling to places such as Greece, Australia, Czechoslovakia, United States, Canada, South Africa, Belize, and most notably China. She published Karst Landforms (Macmillan 1972), and Karst in China: its Geomorphology and Environment (Springer 1995) after many years of work there starting in 1977; the latter is the first comprehensive Western account of China's karst. She created one of the first western published works on the karst found within China, even in a male dominated field.
Examination of peat cores and pollen records indicates that soil erosion (suggesting clearance of woodland for agricultural purposes) was taking place in 3470 BC (the early Neolithic era); much later, from 2460 BC, evidence of arable cultivation exists.Ballantyne, Colin K, and Dawson, Alastair G. "Geomorphology and Landscape Change" in Edwards & Ralston (2003) page 42. As the climate became damper, peat expanded its coverage at the expense of woodland, and post- glacial sea level changes left raised beaches around the coastline 18–45 metres above the present sea-level, especially between Harris and A'Bhrideanach;McKirdy et al. (2007) pages 196, 214 and 286.
From the Parks Service and Environmental Protection Agency, a monitoring program was implemented that involved hydrology, geomorphology, water quality, sedimentation, soil, and vegetation monitoring over a five-year period. Since November 1999, the hydrologic and morphological monitoring in the Crissy Marsh was conducted by the hydrology firm of Philip Williams and Associates, Ltd. (PWA). They monitored water level measurements, beach profile surveys, cross section surveys, marsh elevation transects, detailed 13 topographic surveys of the ebb and flood shoals, bathymetric surveys, and digital terrain modeling. They found that the greatest morphological change was observed in the first 18 months following the restoration.
Although the field of biogeomorphology had not yet been named, Darwin's work represents the earliest examination of a faunal organism influencing landscape process and form. Charles Darwin begins his work on worms with an examination of behavior and physiology, which then moves towards topics related to geomorphology, pedogenesis, and bioturbation. Observations and measurements of soil moved by earthworms, and emphasis on the role of earthworms in formation of humus, fertility of soils, and mixing of soils were all described in the book, which began to change the perspective on earthworms from pest to critical agent of pedogenesis.Meysman, F.J.R., Middelburg, J.J., Heip, C.H.R. 2006.
Shen Kuo devised a geological hypothesis for land formation (geomorphology), based upon findings of inland marine fossils, knowledge of soil erosion, and the deposition of silt.Sivin (1995), III, 23–24. He also proposed a hypothesis of gradual climate change, after observing ancient petrified bamboos that were preserved underground in a dry northern habitat that would not support bamboo growth in his time. He was the first literary figure in China to mention the use of the drydock to repair boats suspended out of water, and also wrote of the effectiveness of the relatively new invention of the canal pound lock.
View of the Taihang Mountains, where Shen Kuo had his epiphany about geomorphology. The ancient Greek Aristotle (384 BC–322 BC) wrote in his Meteorology of how the earth had the potential for physical change, including the belief that all rivers and seas at one time did not exist where they were, and were dry. The Greek writer Xenophanes (570 BC–480 BC) wrote of how inland marine fossils were evidence that massive periodic flooding had wiped out mankind several times in the past, but never wrote of land formation or shifting seashores.Desmond (1975), 692–707.
She attained a BA Hons in 1952 and DipEd in 1953, and went on to spend five months studying applied geomorphology at the University of Strasbourg. Subsequently, in 1958, she became one of the first ever woman PhD graduates in geography at the University of Glasgow. After tutoring at two British universities, she became fed-up with being overlooked for higher academic positions, due to what she described as "an inbred feeling that this was not a women’s world". Through George Jobberns she heard about a lecturer position on the other side of the world, at the University of Canterbury's Department of Geography.
Wave-cut ridges on the beach The Blue Anchor to Lilstock Coast Site of Special Scientific Interest (SSSI) provides an outstanding series of sections through the Early Jurassic Lower Lias, spanning the Hettangian and Pliensbachian stages and named the "Lilstock Formation". This sequence and the good Rhaetian succession beneath are repeatedly affected by faulting, making it of interest to geologists and fossil hunters. It also displays coastal geomorphology which demonstrates a particularly well- developed series of intertidal shore platforms varying in width from about 200–600 m. The cliff and beach are rich in reptile remains, including complete skeletons.
The origins of the Warner College of Natural Resources can be traced to CSU's first forestry course in 1904.Warner College of Natural Resources, College History Page Accessed February 15, 2008. Over the following 100 years the College has grown to become a comprehensive natural resources college, and contains the academic departments of Human Dimensions of Natural Resources; Geosciences; Fish, Wildlife and Conservation Biology; Forest and Rangeland Stewardship; and Ecosystem Science and Sustainability. Research areas include forest sciences, fisheries, wildlife and conservation biology, geology, geophysics, hydrogeology, geomorphology, ecosystem science, rangeland ecology, recreation and tourism, watershed management, and environmental sciences.
The Environment Agency's current "Parrett Catchment Flood Management Plan", published in December 2009, divides the Parrett catchment area into eight sub-areas, with the Somerset Levels and Moors falling into sub-area 6 and Bridgwater falling into sub-area 7. As part of the published flood risk assessments for both these sub-areas, it is recognised that: at a future date a tidal clyse may be needed on the Parrett; this causes a funding dilemma; and, geomorphology studies of the Parrett and the Tone are needed to help address many of the uncertainties associated with a tidal exclusion project.
During this first stage, the terrain is steeper and more irregular. Over time, the currents can carve wider valleys ("maturity") and then start to wind, towering hills only ("senescence"). Finally, everything comes to what is a plain flat plain at the lowest elevation possible (called "baseline") This plain was called by Davis' "peneplain" meaning "almost plain" Then river rejuvenation occurs and there is another mountain lift and the cycle continues. Although Davis's theory is not entirely accurate, it was absolutely revolutionary and unique in its time and helped to modernize and create a geography subfield of geomorphology.
Gilbert's 1893 drawing of sculpture around Mare Imbrium Derailed train after the 1906 San Francisco earthquake; photo by G.K. Gilbert He joined the Harriman Alaska Expedition in 1899. Two weeks after the 1906 San Francisco earthquake, Gilbert took a series of photographs documenting the damage along the San Andreas fault from Inverness to Bolinas. Gilbert is considered one of the giants of the sub- discipline of geomorphology, having contributed to the understanding of landscape evolution, erosion, river incision and sedimentation. Gilbert was a planetary science pioneer, correctly identifying lunar craters as caused by impacts, and carrying out early impact-cratering experiments.
Relief map showing location Lake Burton is the only meromictic lagoon that is part of the Antarctic Specially Protected Area (ASPA) No. 143, within East Antarctica. The lake is also defined as lagoon as it characterizes a stage in the biological and physio- chemical evolution of a terrestrial water body from the marine environment namely, the geological creation of a lake. ;Entry restrictions Entry to the protected area, including the lake, is controlled by the Australian government. Permits are strictly issued only for specific scientific research in the field of paleontology, paleoclimate, geology, geomorphology, glaciology, biology and limnology.
The 1919 edition of The Encyclopedia Americana: A Library of Universal Knowledge further adjusted the definition to be "Physiography (geomorphology), now generally recognized as a science distinct from geology, deals with the origins and development of land forms, traces out the topographic expression of structure, and embodies a logical history of oceanic basins, and continental elevations; of mountains, plateaus and plains; of hills and valleys. Physical geography is used loosely as a synonym, but the term is more properly applied to the borderland between geography and physiography; dealing, as it does, largely with the human element as influenced by its physiographic surroundings".
It is a lowland platform, alongside the sea with a shoreline forming small black sand beaches and basalt rocky coastlines of varying dimensions. It geological form developed from the lava fields and landslides caused by erosion from the high cliffs, above which are the peaks of Pico Negro and Pico do Laurenzo. These conditions, along with cliffs and maritime coastline has resulted in the area being designated as a Special Protection Zone (ZPE) due to its isolation, geomorphology and unique ecosystem. The ZPE includes not only portions of the fajã platform but also the cliffs and shoreline.
Professor Rutkowski dealt with both basic and application research. In the first period of his scientific career he mainly studied petrography, sedimentation and physical properties of carbonate rocks, sandstones, gravels and mineral resources. After his transfer to the Department of Geological Cartography, his research interests extended to issues of Quaternary geology, geomorphology, as well as geological mapping. His greatest achievements included research into the lithology of the Niecka Niedziańska chalk, conditions of sedimentation and lithology of Sarmatian limestones from the south-western Świętokrzyskie Mountains, tectonics and Quaternary deposits around Kraków, as well as the environment of Wigry Lake.
The Undercliff at St Lawrence The local geomorphology defines the town. The Isle of Wight has complex geology of folded layers of sedimentary rocks (Greensand, chalk, and Gault clay), with Ventnor itself situated on the Undercliff, which is the largest urban landslide complex in North West Europe. According to the council's Shoreline Management Plan, the "medium to high sandstone, clay or chalk debris cliffs...are important for their geomorphological, ecological and entomological interest". A significant area is built on the Gault clay, known locally as 'blue slipper', which when saturated allows the rocks above to suffer from landslip.
In planetary nomenclature, a fossa (pl. fossae ) is a long, narrow depression (trough) on the surface of an extraterrestrial body, such as a planet or moon. The term, which means "ditch" or "trench" in Latin, is not a geological term as such but a descriptor term used by the United States Geological Survey (USGS) and the International Astronomical Union (IAU) for topographic features whose geology or geomorphology is uncertain due to lack of data or knowledge of the exact processes that formed them. Fossae are believed to be the result of a number of geological processes, such as faulting or subsidence.
Bioturbation's importance for soil processes and geomorphology was first realized by Charles Darwin, who devoted his last scientific book to the subject (The Formation of Vegetable Mould through the Action of Worms). Darwin spread chalk dust over a field to observe changes in the depth of the chalk layer over time. Excavations 30 years after the initial deposit of chalk revealed that the chalk was buried 18 centimeters under the sediment, which indicated a burial rate of 6 millimeters per year. Darwin attributed this burial to the activity of earthworms in the sediment and determined that these disruptions were important in soil formation.
It is considered proven that the Black Forest was heavily glaciated during the peak periods of at least the Riss and Würm glaciations (up to about 10,000 years ago). This glacial geomorphology characterizes almost all of the High Black Forest as well as the main ridge of the Northern Black Forest. Apart from that, it is only discernible from a large number of cirques mainly facing northeast. Especially in this direction snow accumulated on the shaded and leeward slopes of the summit plateau to form short cirque glaciers that made the sides of these funnel-shaped depressions.
The same year he was awarded with a Decoration of Honour for Services to the Republic of Austria. In 2008 he was promoted to Emeritus Professor of Physics. In 2010 he was awarded by Austrian Academy of Sciences with an Erwin Schrödinger Prize, and a year later he became a Fellow of the American Association award for the Advancement of Science. Besides physics, his other researched include works in archaeology, art, atmospheric science, atomic and molecular physics, biomedicine, environmental physics, forensic medicine, Egyptology, geochronology, geomorphology, geophysics, glaciology, groundwater dating, nuclear astrophysics, nuclear physics, oceanography, and paleoclimatology.
She is currently the Co-Director of the EPSRC Centre for Doctoral Training in Science and Engineering in Art, Heritage, and Archaeology (SEAHA). Since 2019 she has held the position of Chair of the British Society for Geomorphology, having previously been Chair from 2012 to 2014. Viles was Director of Undergraduate Studies (2008-2011), Director of Research (2012-2015), and Head of the School of Geography and the Environment (2015-2019) at Oxford University, and Vice Provost of Worcester College from 2012-2014. From 2008 to 2011, she was Vice-President (Expeditions and Fieldwork) of the Royal Geographical Society with IBG.
Hollande (1906); Cholley, Les préalpes de Savoie (Genevois/Bauges) et leur avant-pays : étude de géographie régionale (1925); Baulig, Le plateau central et sa bordure méditerranéenne : étude morphologique (1928); Martonne, La Valachie : essai de monographie géographique (1902). produced regional geographies that were both physical and human (even economic). The context chosen for these descriptions was a region, whose contours were not always very firmly fixed scientifically. Undoubtedly because this approach was more structured, many of Vidal's successors, and still more those of Martonne, specialized in a geomorphology that became gradually stronger, but that also, by its narrowness, weakened French geography.
30–35 In the same year, he led an expedition of the first Europeans to climb Mount Kenya.H.J. Mackinder, "A Journey to the Summit of Mount Kenya, British East Africa", Geographical Journal, Vol. 15, No. 5 (May 1900), pp. 453–476. It was during this expedition that eight of his African porters were killed; it is disputed as to who killed them, as both Mackinder and another man, Edward Saunders were recorded issuing death threats. In 1902, he published Britain and the British Seas, which included the first comprehensive geomorphology of the British Isles and which became a classic in regional geography.
Terracettes In geomorphology, a terracette is a type of landform, a ridge on a hillside formed when saturated soil particles expand, then contract as they dry, causing them to move slowly downhill. An example of this is the manger near the Uffington White Horse. It may also be described as a small, irregular step-like formation on steep hillslopes, especially on those used for pasture which are formed by soil creep or erosion of surface soils exacerbated by the trampling of livestock such as sheep or cattle. Synonyms are: catstep cattle terracing, sheep or cattle track.
On Mars, the near- surface wind is not only emitting dust but also modifying the geomorphology of Mars at large time scale. Although it was thought that the atmosphere of Mars is too thin for mobilizing the sandy features, observations made by HiRSE showed that the migration of dunes is not rare on Mars. The global average migration rate of dunes (2 – 120 m tall) is about 0.5 meter per year. Atmospheric circulation model suggested repeated cycles of wind erosion and dust deposition can possibly lead to a net transport of soil materials from the lowlands to the uplands at geological timescale.
James Hedges was born on May 10, 1938, in Iowa City, Iowa to Robert Hedges and Margaret Ayres who were teetotallers for religious reasons. He became interested in the Prohibition Party while in high school after reading an article in a newspaper. He earned a Bachelor of Arts in Musical Performance from the University of Iowa in 1960, then enlisted in the United States Marine Band, in Washington, D.C., where he played tuba for twenty years. In 1972, he earned a Master’s degree in Geography from the University of Maryland and published widely on karst and on periglacial geomorphology.
These induce immediate change in a stream, but sometimes fail to achieve the desired effects if degradation originates at a wider scale. Process-based restoration includes restoring lateral or longitudinal connectivity of water and sediment fluxes and limiting interventions within a corridor defined based on the stream's hydrology and geomorphology. The beneficial effects of process-based restoration projects may sometimes take time to be felt since changes in the stream will occur at a pace that depends on the stream dynamics. Despite the significant number of stream-restoration projects worldwide, the effectiveness of stream restoration remains poorly quantified, partly due to insufficient monitoring.
The city of León de Imabite, known today as León Viejo, has been dated from the initial European contact (1522–1524) up to its abandonment in 1610. Archives information suggests the fact that in this area there was human occupation and was used as an Imabite native burial area. For example, seven (7) funeral burials unearthed at the main altar presented anthropological evidence and characteristic features of prehispanic burials. Furthermore, 4 unearthed specimens are below the soil of the Spanish occupation, that according to the stratigraphic geomorphology are registered at a depth ranging from .60 to 1.80 m.
Dungeness is one of the largest expanses of shingle in Europe. It is of international conservation importance for its geomorphology, plant and invertebrate communities and bird life. This is recognised and protected mostly through its conservation designations as a national nature reserve (NNR), a Special Protection Area (SPA), a Special Area of Conservation (SAC) and part of the Site of Special Scientific Interest (SSSI) of Dungeness, Romney Marsh and Rye Bay. There is a remarkable variety of wildlife living at Dungeness, with over 600 different types of plant: a third of all those found in Britain.
In geomorphology fluvio-thermal erosion is the combined mechanical and thermal erosion of an unfrozen river or stream against ice-rich soils and sediments. The erosional process includes the thawing of ice sediments by a strong water flow and once the surface is unfrozen, mechanical erosion occurs only if hydraulic forces are powerful enough to incise the riverbank material. This kind of erosion sometimes causes the banks to collapse into the river, and when this occurs collapses are commonly controlled by ice wedges. Rivers where this process has been observed include the Lena, the Colville River delta, and the Yukon River.
Discussing the soil and landscape characteristics, this paper gives a broad and detailed overview of the typical Mediterranean environmental conditions, geomorphology, geochemistry, pedology, and anthropogenic impacts on Mediterranean ecosystems. Alongside his main focus on soil forming processes, Yaalon also made contributions to the fields of the history, philosophy and sociology of soil science. He played a key role in the establishment of the ISSS Working Group on the History of soil science (today the IUSS Commission 4.5 - History, philosophy and sociology of soil science). In 1997 he co-edited the book History of Soil Science: International Perspectives.
A coastal development hazard is something that affects the natural environment by human activities and products As coasts become more developed, the vulnerability component of the equation increases as there is more value at risk to the hazard. The likelihood component of the equation also increases in terms of there being more value on the coast so a higher chance of hazardous situation occurring. Fundamentally humans create hazards with their presence. In a coastal example, erosion is a process that happens naturally on the Canterbury Bight as a part of the coastal geomorphology of the area and strong long shore currents.
Gudrun started her scientific career studying Jurassic ammonites from France, but later shifted to Palaeolithic archaeology. In 1964, Corvinus examined the Pravara drainage system in the Nevasa area of Maharashtra through an independent multi-disciplinary project. After a survey on the geomorphology of the entire Pravara Valley, suggested by H.D. Sankalia, Corvinus came across the Archeulian factory site at the junction of Chirki with the Pravara, 2 miles downstream from Nevasa. After being funded by the Wenner-Gren Foundation and Deutsche Forschungsgemeinschaft (the German Research Council), she decided to excavate the site, which lasted 3 winter seasons from 1966–1969.
Map of the Calanques between Marseille and La Ciotat, France The Calanque de Sugiton is the largest located within the city limits of Marseille A calanque (, "inlet"; , plural calanche; , plural calancas) is a narrow, steep-walled inlet that is developed in limestone, dolomite, or other carbonate strata and found along the Mediterranean coast. A calanque is a steep-sided valley formed within karstic regions either by fluvial erosion or the collapse of the roof of a cave that has been subsequently partially submerged by a rise in sea level.Bird, E.C.F., 2008, Coastal Geomorphology: An Introduction, 2nd ed. John Wiley and Sons Ltd.
Professor Sharp specialized in geomorphology and published heavily in glacial terrain (the Sierra Nevada, Blue Glacier in the Olympic Peninsula, and Alaska), Mojave Desert terrain, and the Ruby-East Humboldt Range in north-central Nevada. Sharp retired in 1979 but continued leading geological field trips afterwards (with emphasis on the Grand Canyon geology using rubber rafts). Robert Sharp was a member of the United States National Academy of Sciences and received the National Medal of Science from President George H. W. Bush in 1989. Professor Sharp won the Penrose Medal from the Geological Society of America, its highest honor.
The Rosandra Valley has considerable plant diversity: more than 1,000 fungi, 988 vascular plants, approx. 300 lichens, about 150 bryophytes (mosses and liverworts), and about 100 species of Myxomicetes, for a total of approximately 2,700 infrageneric taxa. The Rosandra Valley reflects the history of the vegetation of the karst, but it has many original features. The geomorphology makes it unique in the Trieste Karst: agriculture was and is limited to small areas of flysch such as near Botazzo, grazing is today almost completely abandoned and even in the past it was made difficult by the steep and stony slopes.
However, this undercurrent diminished over time as more Creswick foresters completed tertiary studies at Melbourne University. Until the 1980s a Forestry, Agriculture or an Earth Science qualification like geomorphology was the traditional tertiary pathway into a land management career. Over time, many VSF graduates left the Forests Commission and went on to establish notable careers in other fields with the National Park Service, Fisheries and Wildlife, Alpine Resorts, Country Fire Authority, Soil Conservation Authority, LandCare, Land Conservation Council, Melbourne Water, teaching at tertiary institutions, consultancy, environmental NGO's, research organisations like the CSIRO and Universities, local government, the private sector, interstate and overseas.
A homoclinal ridge or strike ridge is a hill or ridge with a moderate, generally between 10° to 30°, sloping backslope. Its backslope is a dip slope, that conforms with the dip of a resistant stratum or strata, called caprock. On the other side of the other slope, which is its frontslope, of a homoclinal ridge is a steeper or even cliff-like frontslope (escarpment) that is formed by the outcrop of the caprock. The escarpment cuts through the dipping strata that comprises the homoclinal ridge.Cotton, C.A. (1952) Geomorphology An Introduction to the Study of Landforms.
The Acrocorinth was continuously occupied from archaic times to the early 19th century. Along with Demetrias and Chalcis, the Acrocorinth during the Hellenistic period formed one of the so-called “Fetters of Greece” – three fortresses garrisoned by the Macedonians to secure their control of the Greek city-states. The city's archaic acropolis was already an easily defensible position due to its geomorphology; it was further heavily fortified during the Byzantine Empire as it became the seat of the strategos of the thema of Hellas and later of the Peloponnese. It was defended against the Crusaders for three years by Leo Sgouros.
Peninnis Head is the southernmost point of St Mary’s, Isles of Scilly.Ordnance Survey: Landranger map sheet 203 Land's End The headland is within the Isles of Scilly Area of Outstanding Natural Beauty and part of the Heritage Coast. It is also a Geological Conservation Review site for its Quaternary geomorphology and was first designated a Site of Special Scientific Interest (SSSI) in 1971 for both its biological and geological interests. On the tip of the headland is a squat lighthouse built in 1911 by Trinity House as a replacement for the 17th century lighthouse on St Agnes.
Due to its geographical position on the continental margin of Newfoundland, the Orphan Basin received significant proglacial deposits during the late Quaternary period, mostly from ice crossing the continental shelf. The Labrador Current also played a role, allowing icebergs and proglacial plumes to provide sediment from more distant sources. The western slope of the basin has been recognized as four separate areas based on geomorphology, namely: the North Slope, the slope off Trinity Trough, the South Slope, and the slope off Sackville Spur. The area has had several events combining extensive tectonic activity with the possibility of halokinesis.
Digital morphogenesis is a type of generative art in which complex shape development, or morphogenesis, is enabled by computation. This concept is applicable in many areas of design, art, architecture, and modeling. The concept was originally developed in the field of biology, later in geology, geomorphology, and architecture. In architecture, it describes tools and methods for creating forms and adapting them to a known environment.Kolarevic, Branko (2000). 'Morphogenesis and Computational Architectures', in Proceedings of the 4th Conference of Congreso Iberoamericano de Grafica Digital, SIGRADI 2000 - Construindo (n)o Espaço Digital (Constructing the Digital Space), Rio de Janeiro (Brazil) 25–28 September 2000, ed.
Devoy moved to Cork to continue his research after graduating from Cambridge. In conjunction with his activities in Ireland he went on to hold a number of international appointments. In 1984 he was a Visiting Researcher at the University of Delaware and subsequently served as a Visiting Research Fellow in Geomorphology at the Australian National University in 1987, and as a Research Fellow at the University of Sydney in 1990 and again from 1992-1993. From 1992 he was the founding director of the Coastal and Marine Research Centre (CMRC) at University College Cork, working there until 2002.
Archaeological evidence of human occupation alongside the Parramatta River has been dated back 20,000 years, and is likely to date back much further (people have been dated as being present elsewhere in Australia more than 60,000 years ago - see Australian Aboriginal Prehistoric Sites). Sydney's geomorphology 20,000 years ago was very different from what it is today. In the middle of the last ice age, the Sydney coast was approximately 15 km to the east and what is now Port Jackson (Sydney Harbour) was freshwater creeks and rivers. Wangal predecessors would have been living in the now-submerged coastal area.

Cvijić studied in several languages; in grammar school, he studied English, German and French, which was helpful at university (which had little work translated into Serbian), and wrote his scientific and other papers in those three languages. During the 1888–89 school year Cvijić was a geography teacher at the Second Male Grammar School in Belgrade, and in 1889 enrolled to study physical geography and geology at Vienna University. At that time geomorphology was taught by Albrecht Penck, geotectonics by Professor Sis (president of the Austrian Academy) and climatology by Julius von Hann. House of Jovan Cvijić in Belgrade, street view Cvijić received his PhD from Vienna University in 1893.
Dam building has had the opposite effect, by blocking natural sediment sources to a long section of the Trinity River. Both have had notable impacts on river geomorphology, altering the development of riparian zones and fish habitat. Trinity River near Hoopa The Trinity River watershed borders several major California drainage basins; these are the Mad River and Redwood Creek to the west, the Salmon River and Scott River (tributaries of the Klamath River) to the north, and Clear Creek and Cottonwood Creek (both tributaries of the Sacramento River) to the east and south, respectively. Fir, oak, and pine forests cover about 92 percent of the watershed.
Summerfield, M.A., 1991, Global Geomorphology, Pearson Education Ltd, . The surface of Earth is modified by a combination of surface processes that sculpt landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography. Surface processes comprise the action of water, wind, ice, fire, and living things on the surface of the Earth, along with chemical reactions that form soils and alter material properties, the stability and rate of change of topography under the force of gravity, and other factors, such as (in the very recent past) human alteration of the landscape. Many of these factors are strongly mediated by climate.
Apollo 11 astronaut Buzz Aldrin walking on the surface of the Moon, which consists of lunar regolith (photographed by Neil Armstrong, July 1969). A planetary surface is where the solid (or liquid) material of the outer crust on certain types of astronomical objects contacts the atmosphere or outer space. Planetary surfaces are found on solid objects of planetary mass, including terrestrial planets (including Earth), dwarf planets, natural satellites, planetesimals and many other small Solar System bodies (SSSBs). The study of planetary surfaces is a field of planetary geology known as surface geology, but also a focus of a number of fields including planetary cartography, topography, geomorphology, atmospheric sciences, and astronomy.
The 1960s saw several relevant developments in geology, notably the discoveries of seafloor spreading and Wadati–Benioff zones, and this led to the rapid resurrection of the continental drift hypothesis in the form of its direct descendant, the theory of plate tectonics. Maps of the geomorphology of the ocean floors created by Marie Tharp in cooperation with Bruce Heezen were an important contribution to the paradigm shift that was starting. Wegener was then recognized as the founding father of one of the major scientific revolutions of the 20th century. With the advent of the Global Positioning System (GPS), it became possible to measure continental drift directly.
The timing and amplitude of the seasonal cycle has been altered by global warming. Superimposed on the global rise in sea level, is strong regional and decadal variability which may cause sea level along a particular coastline to decline with time (for example along the Canadian eastern seaboard), or to rise faster than the global average. Regions that have shown a rapid rise in sea level during the past two decades include the western tropical Pacific and the United States northeastern seaboard. These regional variations in sea level are the result of many factors, such as local sedimentation rates, geomorphology, post-glacial rebound, and coastal erosion.
These may also be nationally or internationally significant features. An Earth Science area is one in which the representative feature was created by geologic processes and consists of the physical elements of a natural landscape, such as the bedrock, landforms, and fossils. These are identified by lithology, paleontology, and geomorphology, then classified "into geological themes" according to age, stratigraphy, topography, and other characteristics. A Life Science area is one in which the representative feature consists of the biodiversity of the area and its landscapes, and has not been affected by human development; this includes all indigenous plants and animals, forests and valleys, prairies and savannahs, wetlands, alvars, and bodies of water.
Glacial landforms dominate Banff's geomorphology, with examples of all classic glacial forms, including cirques, arêtes, hanging valleys, moraines, and U-shaped valleys. The pre-existing structure left over from mountain-building strongly guided glacial erosion: mountains in Banff include complex, irregular, anticlinal, synclinal, castellate, dogtooth, and sawback mountains. Many of the mountain ranges trend northwest to southeast, with sedimentary layering dipping down to the west at 40–60 degrees. This leads to dip slope landforms, with generally steeper east and north faces, and trellis drainage, where rivers and old glacial valleys followed the weaker layers in the rocks as they were relatively easily weathered and eroded.
For example, the Royal Botanic Garden, Sydney commissioned sculptor Chris Booth to design a living sculpture (entitled Wurrungwuri) for its grounds, officially unveiled 9 March 2011. One of the two main pieces of the sculpture is a 'sandstone wave', consisting of about 200 tonnes of sandstone blocks in an undulating form reminiscent of the tectonic forces that created the stone. The sculptor says the design is 'inspired by the sandstone stratas it emerges from and, of course, the link to the sea which it cascades towards ... its evolution is from the geomorphology.'Mark Savio, 'A Living Sculpture' in The Gardens, Issue 87 (Summer 2010/11) p. 26.
Legacy sediment (LS) is depositional bodies of sediment inherited from the increase of human activities since the Neolithic. These include a broad range of land use and land cover changes, such as agricultural clearance, lumbering and clearance of native vegetation, mining, road building, urbanization, as well as alterations brought to river systems in the form of dams and other engineering structures meant to control and regulate natural fluvial processes (erosion, deposition, lateral migration, meandering). The concept of LS is used in geomorphology, ecology, as well as in water quality and toxicological studies. LS is distributed in spatially heterogeneous ways throughout a landscape and accumulates to form various landforms.
Such transition zones are called ecotones. Ecoregions can be categorized using an algorithmic approach or a holistic, "weight-of-evidence" approach where the importance of various factors may vary. An example of the algorithmic approach is Robert Bailey's work for the U.S. Forest Service, which uses a hierarchical classification that first divides land areas into very large regions based on climatic factors, and subdivides these regions, based first on dominant potential vegetation, and then by geomorphology and soil characteristics. The weight-of-evidence approach is exemplified by James Omernik's work for the United States Environmental Protection Agency, subsequently adopted (with modification) for North America by the Commission for Environmental Cooperation.
The civil parish of Monte Córdova is situated 30 kilometres from Porto, and accessible by the EN105 motorway to many of the local communities, including Braga, Famalicão and Guimarães. For many centuries, the geomorphology of the terrain was responsible for the relative isolation of its populations. The parish is located at about 410–420 metres above sea level, in an area called the Agrela da Assunção escarpment. Alto de Cabanas is one of the best natural lookouts in the region, and the area of Valinhas, with its monumental oak forests and curious chapel, near the Fervença waterfalls (or the Leça River), are almost obligatory natural sites of the landscape.
His research interests were wide and varied but were rooted in his love of hot deserts and tropical landscapes and his desire to better understand the processes that shape them. Whilst the interpretation and exploration of landscapes formed the central core of Bernard Smith's career, his interest in process studies, and weathering processes in particular, led him onto some of his most significant geomorphological work. Bernard Smith's first publications were on desert geomorphology but his wide interests were also focussed on the formation of desert dust and loess. His interest in desert weathering then started to develop in the direction of building stone decay.
With elevation, Uturuncu is the highest mountain in southwestern Bolivia and dominates its geomorphology, rising about above the surrounding terrain and giving a good view of the surrounding mountains from the summit. The volcano has two summit peaks and high, about apart and separated by a high saddle. It is a stratovolcano with remnants of a crater, and consists of lava domes and lava flows erupted from a number of vents in the central part of the volcano. About 105 lava flows propagate outward from the central sector of the volcano, reaching lengths of and featuring levees, flow ridges and steep, blocky fronts over thick.
Croatia has a number of ecoregions because of its climate and geomorphology, and the country is consequently among the most biodiverse in Europe. There are four types of biogeographical regions in Croatia: Mediterranean along the coast and in its immediate hinterland; Alpine in the elevated Lika and Gorski Kotar; Pannonian along the Drava and Danube; and Continental in the remaining areas. There are 444 protected natural areas in Croatia, encompassing 8.5% of the country; there are about 37,000 known species in Croatia, and the total number of species is estimated to be between 50,000 and 100,000. The permanent population of Croatia by the 2011 census reached 4.29 million.
On graduation Linton initially worked at King's as demonstrator in geology, taking over from S.W.Wooldridge (later the first professor of geography at King's), who had recently completed his doctorate. In 1929 Linton moved to Edinburgh University. He nevertheless continued to collaborate with Wooldridge on a number of publications on the geology and geomorphology of south-east England during the 1930s, culminating in Structure, Surface and Drainage in South-east England (1939, republished 1955). During World War II Linton carried out photo reconnaissance with the Royal Air Force Volunteer Reserve, later publishing The Interpretation of Air Photographs (1947). Following the war he was appointed professor of geography at Sheffield University in 1945.
The Hellenic National Meteorological Service (HNMS) weather station of Eleusis has an average maximum July temperature of (1958–2001 HNMS) The Eleusis phenomenon is not yet completely understood; however, factors of geomorphology, warm water masses in the summer and warm winds might be responsible for its summer climate. According to Kassomenos and Katsoulis (2006), based on 12 years of data (1990–2001), the industrialization of west Attica, where at least 40% of the industrial activity of the country is concentrated, could be the cause of the warm climate of the zone. According to the Köppen Climate Classification system, Eleusis has a hot-summer Mediterranean climate, abbreviated "Csa" on climate maps.
For example, serpentinite is a kind of rock formed in a process called serpentinization, in which a host mineral produces a pseudomorph, and the original mineral is eventually replaced and/or destroyed, but is still present until the process is complete. Within geomorphology a relict landform is a landform that took form from geomorphic processes that are not active at present. In a Scandinavian context, this is often meant to imply that relict landforms were formed before the last glaciation and survived it under cold- based parts of the ice sheet. Climatic geomorphologist Julius Büdel estimated that 95% of mid-latitude landforms are relict.
Geomorphology of the Dinaric Alps. Cem is found in the Prokletije/Albanian Alps subdivision in B31 The geomorphological features of the Cem basin have their origin in the tectonic activity of the Alpine orogeny, which has been forming the Dinaric Alps and its southern range, the Prokletije since the Late Mesozoic and Cenozoic era. The Cem basin is in the High Karst Unit. In this sub-unit, tectonic activity lifts the landmasses vertically and carbonate rocks form a large part of the landscape, which is defined by fluvial processes like the deposition of carbonate sediments by the river caused by the flow of the river.
In 2002, she won BBC Talent's Science on Screen competition and co-presented the Tomorrow's World Award Show on BBC One. Then, in 2005, Cockburn co-presented What the Ancients Did for Us with Adam Hart-Davis for BBC Two, exploring the scientific legacy of ancient civilisations, before joining the team of Rough Science (also on BBC Two), replacing Kathy Sykes for the sixth series. Expert contributions for the BBC Television series Coast have included explanations of Scottish geomorphology, geoarchaeology and engineering geology. In 2008, she presented the BBC Television/Open University documentary series Fossil Detectives for which she also wrote the companion book.
Geomorphology is the scientific study of landforms and the processes that shape them. In terms of analogue sites, scientists search for locations on Earth that exhibit similar landforms such as can be found on exploration targets like the Moon, Mars or even asteroids and comets. The idea is to confront astronauts, robots or scientific equipment with sites that resemble in their geologic appearance those extraterrestrial surfaces. Examples are volcanic sites which resemble lunar terrain (regolith), polar locations and glaciers that can be compared to the poles of Mars or of Jupiter moon Europa, or terrestrial lava tubes which can also be found on the Moon or Mars.
In 1909, Geddes assisted in the early planning of the southern aspect of the Zoological Gardens in Edinburgh. This work was formative in his development of a regional planning model called the "Valley Section".This model illustrated the complex interactions among biogeography, geomorphology and human systems and attempted to demonstrate how "natural occupations" such as hunting, mining, or fishing are supported by physical geographies that in turn determine patterns of human settlement. The point of this model was to make clear the complex and interrelated relationships between humans and their environment, and to encourage regional planning models that would be responsive to these conditions.
Over this layer is a dense soil with sand and medium-sized rock fragments where there are remains of abundant minerals. According to the general classification of soils, Antofagasta is founded on clay loam soils of the type I and II. The city has an irregular geomorphology by the presence of steep hills (400–500 m) that are part of Chilean Coast Range, in its eastern edge, and the Pacific Ocean to the west. The formation of the rock mass, it makes the shoreline slope is very steep (Coloso, south of Antofagasta). The coastal edge of the city has volcanic sediments, in contrast to the formation of hills of sand.
In geology and geomorphology, the term patina is used to refer to discolored film or thin outer layer produced either on or within the surface of a rock or other material by either the development of a weathering rind within the surface of a rock, the formation of desert varnish on the surface of a rock, or combination of both. It also refers to development as the result of weathering of a case-hardened layer, called cortex by geologists, within the surface of either a flint or chert nodule.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, J.A., eds. (2005) Glossary of Geology (5th ed.).
David R. Montgomery is a Professor of Earth and Space Sciences at the University of Washington in Seattle, where he is a member of the Quaternary Research Center. Montgomery received his B.S. in geology from Stanford University in 1984, and his Ph.D. in geomorphology from University of California, Berkeley in 1991. His research addresses the evolution of topography and the influence of geomorphological processes on ecosystems and human societies. His published work includes studies of the role of topsoil in human civilization, the evolution and near-extirpation of salmon, geomorphological processes in mountain drainage basins, the evolution of mountain ranges, and the use of digital topography.
Acrocorinthis, the acropolis of ancient Corinth, is a monolithic rock that was continuously occupied from archaic times to the early 19th century. The city's archaic acropolis, already an easily defensible position due to its geomorphology, was further heavily fortified during the Byzantine Empire as it became the seat of the strategos of the Thema of Hellas. Later it was a fortress of the Franks after the Fourth Crusade, the Venetians and the Ottoman Turks. With its secure water supply, Acrocorinth's fortress was used as the last line of defense in southern Greece because it commanded the isthmus of Corinth, repelling foes from entry into the Peloponnesian peninsula.
An alluvial river is one in which the bed and banks are made up of mobile sediment and/or soil. Alluvial rivers are self-formed, meaning that their channels are shaped by the magnitude and frequency of the floods that they experience, and the ability of these floods to erode, deposit, and transport sediment. For this reason, alluvial rivers can assume a number of forms based on the properties of their banks; the flows they experience; the local riparian ecology; and the amount, size, and type of sediment that they carry.Leopold, Luna B., Wolman, M.G., and Miller, J.P., 1964, Fluvial Processes in Geomorphology, San Francisco, W.H. Freeman and Co., 522p.
In his retirement Zamora has also self-published a science fiction book, and several small books while investigating the Carolina Bays; in his 2017 paper "A model for the geomorphology of the Carolina Bays" he proposed that the "Carolina Bays are the remodeled remains of oblique conical craters formed on ground liquefied by the seismic shock waves of secondary impacts of glacier ice boulders ejected by an extraterrestrial impact on the Laurentide Ice Sheet". His research was based on geometrical analysis of the Carolina Bays using Google Earth in combination with LiDAR data. The theory is not widely accepted. Many other theories have been proposed to account for their formation.
Born in Reudnitz near Leipzig, Penck became a university professor in Vienna, Austria, from 1885 to 1906, and in Berlin from 1906 to 1927. There he was also the director of the "Institute and Museum for Oceanography" by 1918. He dedicated himself to geomorphology and climatology and raised the international profile of the "Vienna School of physical geography". With Eduard Bruckner, he was co-author of Die Alpen im Eiszeitalter, a work in which the two scientists identified the four ice ages of the European Pleistocene (Gunz, Mindel, Riss, Würm); these being named after the river valleys that were the first indication of each glaciation.
Ernst Valdemar Antevs (November 20, 1888 – May 19, 1974) was a Swedish- American geologist and educator who made significant contributions to Quaternary geology, particularly geomorphology and geochronology. Ernst Valdemar Antevs was born on a farm in the Vartofta-Åsaka parish of Skaraborg, (now Västra Götaland), Sweden. He attended Stockholm University where in 1917, he was awarded his Ph.D. in geology. He was employed as a docent at the University of Stockholm from 1917 to 1935. He was also a research associate for the American Geographical Society (1921 to 1922), the Carnegie Institution of Washington (between 1922-1940), Geological Survey of Canada (between 1923- 1930), and Harvard University (1924-1926).
The Table, a tuya in British Columbia. Some researchers have attempted to analogize Ganges Mensa to the tuyas of British Columbia, which are thought to have formed as a result of subglacial volcanic activity. The Ganges Mensa province and other interior layered deposits in Valles Marineris have been strongly analogized to the Azas Plateau, a region in the Tuva Republic (a federal subject of Russia) near Lake Baikal and the Mongolian border. The Azas Plateau volcanic field is thought to have formed through subglacial volcanism; that mechanism is used accordingly to interpret the geomorphology of Ganges Mensa, which has been analogized to a terrestrial landform known as a tuya.

D. I. Mushketov's geological interests were very wide including the worldwide study of tectonics and seismology, but he concentrated his work in Central Asia, covering also the fields of stratigraphy, geomorphology, glaciers, and mineral resources. His scholarly output was prodigious, with "more than 50 scientific works, several textbooks and manuals included, before 1926". Between 1909 and 1916 he carried out the geological survey of eastern Fergana which contributed to the geological map of Central Asia. His name is particularly well known for the high-quality revisions and additions that he made to each edition of the textbook on physical geology that was originally written by his father (published in 1888–91).
Northern Ireland consists of mostly hilly landscape and its geography includes the Mourne Mountains as well as Lough Neagh, at , the largest body of water in the UK. The overall geomorphology of the UK was shaped by a combination of forces including tectonics and climate change, in particular glaciation in northern and western areas. The tallest mountain in the UK (and British Isles) is Ben Nevis, in the Grampian Mountains, Scotland. The longest river is the River Severn which flows from Wales into England. The largest lake by surface area is Lough Neagh in Northern Ireland, though Scotland's Loch Ness has the largest volume.
In 1943-1946 he was in "Stepsgeo" team fighting in high-mountains of the Caucasus and participated in the military-geographical expeditions in South Georgia. Being demobilized from the army in 1946, in a very short time he got ready his dissertation - "Karst of fragmental rock, its geomorphological characteristics in the light of general karstology, Central Megrelia as an example (Western Georgia)" and successfully defended his master's degree in 1947.Geomorphology, Russian Academy of Sciences, October–December, № 4 - 2002, pp. 121. Since 1947, Levan Maruashvili worked as an assistant professor at Kutaisi Pedagogical Institute, and from 1949 to 1953 took over the Department of Geography at Sokhumi Pedagogical Institute.
In the 1920s and 30s Wooldridge lectured at King's on a combined geography and geology course with the London School of Economics (LSE). In the Joint School of Geography King's offered Geomorphology, Meteorology, Biogeography and the History of Geographical Discovery, while the LSE offered the Regional and Economic aspects, Historical Geography, and the Distribution of Man. During World War II this arrangement was disrupted by the evacuation of King's to Bristol, requiring Wooldridge to teach human geography. His conversion to geography complete, he became professor of geography at Birkbeck College, London in 1944, returning to King's in 1947 as its first professor of geography and remaining until his death in 1963.
The lighthouse was built in 1913 and consists of a granite quadrangular tower, high, with balcony and lantern atop a 2-storey keeper's house. The building and the tower are painted white, the lantern dome in grey metallic. The lighthouse was electrified in 1935 and automated in 1975 when the last keeper left; in the years 1946 and 1947 the work was carried out by a woman, Genoveffa Balzano. For twenty years the lighthouse remained in complete abandonment until 1995, when the structure was given, by the Marina Militare in free perpetual concession, to the Universities of Trieste and Cagliari as seat of the Coastal and Marine Geomorphology Group (OCEANS).
The use of weathering rinds in relative dating is widely used in Arctic, Antarctic, and alpine regions and in the correlation of glacial moraines and tills and fluvial sediments and terraces.Goudie, AS, 2004, Rind, Weathering. in AS Goudie, ed., pp. 853-855, Encyclopedia of Geomorphology, vol. 2 J-Z Routledge, London-New York.

The form of the mountain takes on a curious appearance when viewed at a distance from its southern silhouette. It has the appearance of a huge, overweight man laughing, with its peak forming the head and the rest of its form below, forming the laboured shape of a legless, bloated man. This curious shape has earned the mountain the nickname of "Man Mountain" by tourists. Whilst there are no doubt mythological explanations among the surrounding tribal peoples as to how the mountain acquired its shape, geomorphology would suggest that this is the product of millennia of faulting activity coupled by the chiselling effects of wind erosion on the bare rock outcrops.
A number of Geological Conservation Review sites have been identified within the national park, about half of which have been designated as sites of special scientific interest (SSSIs). The Falls of Dochart, the delta of the River Balvag (Loch Lubnaig Marshes) and the River Endrick have all been notified as SSSIs for their fluvial geomorphology whilst mass movement sites at Ben Vane, Glen Ample and Beinn Arthur (The Cobbler) have been declared GCR sites but not notified as SSSIs. Other Quaternary sites include Croftamie, Portnellan-Ross Priory-Claddochside and the Menteith moraine which is partly within Flanders Moss SSSI. Igneous GCRs include Balmaha & Arrochymore Point (as Conic Hill SSSI) and Garabal Hill.
Bruno Messerli (17 September 1931, in Belp – 4 February 2019) was a Swiss geographer and university professor who focused on high mountains and highland-lowland linkages. He was appointed Full Professor of Geomorphology in 1968 by the University of Bern, where he taught and carried out research until his retirement in 1996. He contributed significantly to the inclusion of a mountain agenda, Chapter 13 -- Managing Fragile Ecosystems -- Sustainable Mountain Development in Agenda 21, the official action plan of the United Nations Conference on Environment and Development (UNCED), also known as the Rio de Janeiro Earth Summit, the Rio Summit, the Rio Conference, and the Earth Summit, held in Rio de Janeiro from 3 to 14 June in 1992.
Karst limestones as statuary in Shenyang Imperial Palace, Shenyang, China Johann Weikhard von Valvasor, a pioneer of the study of karst in Slovenia and a fellow of the Royal Society for Improving Natural Knowledge, London, introduced the word karst to European scholars in 1689, describing the phenomenon of underground flows of rivers in his account of Lake Cerknica.Paul Larsen, Scientific accounts of a vanishing lake: Janez Valvasor, Lake Cerknica and the New Philosophy, 2003. Jovan Cvijić greatly advanced the knowledge of karst regions, so much that he became known as the "father of karst geomorphology". Primarily discussing the karstic regions of the Balkans, Cvijić's 1893 publication Das Karstphänomen describes landforms such as karren, dolines and poljes.
The place's biodiversity value lies in the assemblage of species rather than with the number of species. The diversity of geomorphology and climatic gradients has resulted in a complex mixture of vegetation in a relatively small area. Unusual plant associations are demonstrated in the gradation from the wet coastal forests in the east of the place to the semi-arid tree species of poplar box (Eucalyptus populnea), bulloak (Allocasuarina luehmanniiand), and Melaleuca spp on the dry ridges occurring above the seasonally waterlogged valleys and swamp communities in the western portion of the place. The presence of stands of the semi-arid poplar box woodland on the beachfront just above the normal high tide range is an uncommon occurrence.
Wilhelmy studied geography, geology und ethnology at the universities of Giessen, Bonn, Vienna (1930) and Leipzig. In 1932 he finished his doctoral degree—supervised by Alfred Hettner's disciple Heinrich Schmitthenner—that treated the geomorphology of western Bulgaria Die Oberflächenformen des Iskergebietes: Eine Morphogenese Westbulgariens. Also his Habilitation in Kiel, as Oskar Schmieder's assistant (from 1932), was dedicated to the Bulgarian Balkan mountains' settlement and economy—Hoch-Bulgarien: Die ländlichen Siedlungen und die bäuerliche Wirtschaft (1935), Sofia, Wandlungen einer Großstadt zwischen Orient und Okzident (1936). He worked at the University of Kiel 1939–1942 (as contracted lecturer), 1942–1954 as associated professor, interrupted by a work period as meteorologist and research director in Ukraine (1941—1943).
The river's diversity comes from its active geomorphology, which has created a number of natural features that support niche ecologies; it also comes from there being a limited number of trees on the river bank, allowing in light; and also the riverbed stability in the lower reaches of the river. A majority of the SSSI runs through Devon; only runs through Dorset. The underlying geology of the riverbed is alluvium with areas of valley gravel, clay, shale and marl. The fish life in the river is considered of European interest; ;other animals include more generally includes salmon, bullheads, otters, medicinal leeches and kingfishers, whilst there is a diverse aquatic and marginal plant life.
Retrieved 22 May 2011. (see also Geology and Geomorphology), which not only give visitors a good insight into the geology of the region, but also the surprising adaptability of sandstone rock vegetation, especially the heathers, the undemanding grasses and the deformed Scots pine trees. Another feature of this biotope are peregrine falcons, which nest in the rocks and are under strict conservation measures (including access restrictions for climbers and walkers). Well-known rock formations in the Dahner Felsenland ("Dahn Rock Country") are the Devil's Table near Hinterweidenthal, the Jungfernsprung, the Hochstein and the two pinnacles of the Bride and Groom, which all lie in the area around the little town of Dahn.
Areas of research frequently published in Bulletin of Engineering Geology and the Environment include: study and solution of engineering and environmental problems arising from the interaction between geology and the activities of humanity. Geomorphology, structure, stratigraphy, lithology, and groundwater conditions of geological formations; characterization of the mineralogical, physico-geomechanical, chemical and hydraulic properties of earth materials involved in construction, resource recovery and environmental change; assessment of the mechanical and hydrological behavior of soil and rock masses; prediction of changes to the above properties with time; determination of the parameters to be considered in analyzing the stability of engineering works and earth masses; maintenance of the environmental condition and properties of the terrain.
Enayat Ahmad wrote several research papers on various aspects of geology, geography, and geomorphology of India, many of which were published in the journal that was published from Ranchi University and some in the journal of Aligarh Muslim University. His initial publications on what developed into the Ahmad theory were first published in the Geographical Outlook and Geographer. One of his first published papers, based on his thesis work, was on human settlements in Uttar Pradesh. He wrote Five Cities of the Gangetic Plain: A Cross-Section of Indian Cultural History in 1950 with Oskar Spate, a well-known geographer, and The Rural Population of Bihar in 1961, both of which were published in the Geographical Review.
The cave developed in a breccia often found at the contact between Silurian Table Mountain Series quartzite and Cretaceous Uitenhage Series quartzitic sandstone. Excavations were carried out in 1964-5 by Ray R. Inskeep and again in 1970-1 by Inskeep and Richard G. Klein. The geology and geomorphology of Robberg were well documented by John Rogers in 1966. The cave has yielded rich archaeological material covering its intermittent Middle and Later Stone Age occupation dating from a few hundred to more than 125,000 BP. The cave was abandoned between 40,000 to 20,000 BP during the last Ice Age when the sea level here dropped some 130 metres, the coastline moving about seaward.

One of his great uncles was Sir Alfred Wills, a well-known Victorian mountaineer and judge. Sir Alfred was a founder member and early President of the Alpine Club, and was interested in the origin and shaping of the Alps – an interest which may well have influenced his great-nephew. Sir Alfred translated from French into English one of the classic early works on the geomorphology and glaciology of the mountains, Louis Rendu's Théorie des Glaciers de la Savoie (1840). As a judge, Sir Alfred presided over the second 1895 Oscar Wilde trial and sentenced Wilde to two years in Reading gaol. Jack Wills’s father, William Leonard Wills (1858–1911), was a science graduate of Owens College, Manchester.
The existence of both linear and barchan dunes in the same location is apparently incompatible, as that would seem to imply the co- existence of unidirectional and bidirectional winds in the same place. Research has been undertaken to explain the coexistence of linear and barchan dunes in Hyperboreae Undae. One paper explains the change from linear to barchan dunes in adjacent locations, by proposing a wind model that changes from bidirectional to unidirectional due to the influence of local topography; it is proposed that bidirectional winds change to unidirectional due to funneling action introduced by local geomorphology. Although valid for neighbouring dune locations, this theory cannot explain how linear and barchan dunes can coexist in the same location.
A flood basalt is the result of a giant volcanic eruption or series of eruptions that covers large stretches of land or the ocean floor with basalt lava. Flood basalt provinces such as the Deccan Traps of India are often called traps, after the Swedish word trappa (meaning "stairs"), due to the characteristic stairstep geomorphology of many associated landscapes. Michael R. Rampino and Richard Stothers (1988) cited eleven distinct flood basalt episodes occurring in the past 250 million years, creating large volcanic provinces, lava plateaux, and mountain ranges. PDF via NASA However, more have been recognized such as the large Ontong Java Plateau, and the Chilcotin Group, though the latter may be linked to the Columbia River Basalt Group.
In a study of eggs laid in Rhizophora mangle L. (red mangrove) and Avicennia germinans L. (black mangrove) forest basins, egg occurrence was correlated with elevation and detritus level. Oviposition was directed from black mangrove basins to red mangrove basins, possibly due to reduced detritus and reduced organic content in the soil caused by black mangrove grazing by Melampus coffeus L., a snail. Because eggshells and eggs share the same habitat, it is suggested that oviposition may be delineated using eggshells. Eggshell sampling analysis from 34 mangrove forest sites indicated that all mangrove basin forests can yield successful Ae. taeniorhynchus production, regardless of forest geomorphology, soil, and vegetation but recently flooded sites are most optimal.
After completing his PhD, Pattyn then worked as a postdoctoral researcher at the National Institute of Polar Research, Tokyo, Japan (1999-2000) before coming back to Belgium as a research associate at the Vrije Universiteit Brussel. In 2000, he started to teach geomorphology and climatology at the Université libre de Bruxelles where he became a professor in 2011. Since 2006, he has also become co-director of the Laboratoire de Glaciologie of the Université libre de Bruxelles. He is currently Chairman of the Belgian National Committee on Antarctic Research, the Belgian branch of the Scientific Committee on Antarctic Research and the vice-president of the International Glaciological Society and Associate Chief Editor of Journal of Glaciology.
Gampola, or so called Gangasiripura because of the Mahaweli (Mahaweli Ganga) flowing by its side, is a beautiful town itself stands 300 – 500 m altitude, situated in a valley surrounded by hills and located near to Kandy. Geologically the region belongs to the Highland Complex of Sri Lanka and major rock formation is Precambrian charnockite gneiss with strips of quartz and biotite gneiss here and there. Soil profile of the region could identify as Red Yellow Podzolic soils and Mountain Regosols. Mean annual rainfall is in between 3000 – 3500 mm and mean annual temperature is in between 20-25 C. Due to the geomorphology of the Gampola and its vicinity, which characterised by steep hills stand from plain, it was declared as a landslide prone area.
The science relating to the geographical, geological, and hydrological aspects of water bodies and to changes to these aspects in response to low variations and to natural and human caused events, such as heavy rainfall or channel straightening is the hydro-geomorphology. Hydrogeomorphology describes and evaluates the environment, in which water circulates, thus providing the information to understand the situation and to make the proper decisions. Quantitative study of drainage basin provides the theoretical base for the hydrogeomorphic approach, suggesting that certain unvarying drainage basin characters can be correlated to the hydrologic response of a basin. The measurable description of a drainage basin can be grouped in to linear aspect of channel network, areal aspect of drainage basin, relief aspect of channel system and basin form.
Beaver dams, as this one in Tierra del Fuego, constitute a specific form of zoogeomorphology, a type of biogeomorphology. The interaction of living organisms with landforms, or biogeomorphologic processes, can be of many different forms, and is probably of profound importance for the terrestrial geomorphic system as a whole. Biology can influence very many geomorphic processes, ranging from biogeochemical processes controlling chemical weathering, to the influence of mechanical processes like burrowing and tree throw on soil development, to even controlling global erosion rates through modulation of climate through carbon dioxide balance. Terrestrial landscapes in which the role of biology in mediating surface processes can be definitively excluded are extremely rare, but may hold important information for understanding the geomorphology of other planets, such as Mars.
The White Mountains range in New Hampshire spans the north-central portion of the state, with Mount Washington the tallest in the northeastern U.S. Shaded relief map of New Hampshire In the flatter southwest corner of New Hampshire, the landmark Mount Monadnock has given its name to a class of earth-forms – a monadnock – signifying, in geomorphology, any isolated resistant peak rising from a less resistant eroded plain. Major rivers include the Merrimack River, which bisects the lower half of the state north-south and ends up in Newburyport, Massachusetts. Its tributaries include the Contoocook River, Pemigewasset River, and Winnipesaukee River. The Connecticut River, which starts at New Hampshire's Connecticut Lakes and flows south to Connecticut, defines the western border with Vermont.
Balch's investigations into geomorphology and hydrology led to his decision to try to find the origins of the water that rose to the surface at Wookey Hole Caves, the source of the River Axe. In 1901, he led a team of miners and cavers to dig into Swildon's Hole, where he found the 'Forty Foot Pot' as well as chambers full of stalagmites. Despite the publicity around the find, Balch refused to disclose the location of the cave as he believed it was too dangerous for amateur explorers. The farmer who owned the land denied them entrance the following year, turning the valley into a fish farm, so the team headed upstream where they discovered Eastwater Cavern, one of Balch's personal favourites.
The fort may be of Iron Age origin, but was (re)built and fortified as a burh by King Alfred, as part of his defence against Viking raids from the Bristol Channel around 878 AD. The Blue Anchor to Lilstock Coast SSSI is a 742.8 hectare geological Site of Special Scientific Interest. It provides an outstanding series of sections through the Early Jurassic Lower Lias, spanning the Hettangian and Pliensbachian Stages and named the "Lilstock Formation". This sequence and the good Rhaetian succession beneath are repeatedly affected by faulting, making it of interest to geologists and fossil hunters. It also displays coastal geomorphology which demonstrates a particularly well-developed series of intertidal shore platforms varying in width from about 200-600m.
Melik was born in the village of Črna Vas in Carniola, part of Austria-Hungary. Before and during World War I, he studied at the University of Vienna, graduating in 1916 in history and geography. Later he was employed as a secondary school teacher. In 1926–1927 he became a senior university teacher at the Faculty of Arts of the University of Ljubljana, in 1932 a senior lecturer, and then in 1938 a professor. In 1927 he received his PhD from the Faculty of Arts with his dissertation on the settlement of the Ljubljana Marshes. Between 1938 and 1966, he was a professor of geomorphology at the Department of Geography at the University of Ljubljana, succeeding professor Artur Gavazzi in 1938.
Artifact density was assessed using GIS and statistical correlations, and it was determined that the stratification of larger artifacts remaining on the surface while smaller artifacts had been pushed below could be attributed to trees falling and disrupting the geomorphology of the site. Lithic samples of on and off-site materials from the excavation were also used for geochemical and petrological analysis, conducted independently. Excavation of the Two Dogs Site yielded 32,904 artifacts in total, which were found to mostly be dacite with some quartz and other materials appearing at significantly lower frequencies. Petrographic analysis indicated that all samples of local lithic materials were felsic volcanic rocks, and the samples of off-site lithics were found to be felsic volcanic siltstones.
Ecomuseu of Seixal, constructed from a river mill constructed during the 18th century A view inside a former cork factory in Seixal A view of traditional Pauliteiros from the Avante! Festival The toponymy Seixal comes from a type of smooth stone (seixo) that is found in rivers; the name evolving from the name used to describe the geomorphology of the region. Since the Roman era, the Tagus bay has been a region of human settlement, from many of the archaeological discoveries at Quinta do Rouxinol, in Corroios, and Quinta de S. João, in Arrentela (beginning in the period of the Portuguese Age of Discovery). A land of fishermen and signeurial holdings, the municipality of Seixal evolved over the centuries, always with the connection to the river.

Physical oceanography is the sub-domain of oceanography which focuses on the study of physical conditions and processes within the ocean, including the physical properties and circulation of ocean waters. These matters influence the biodiversity by providing the setting in which the ecology and biodiversity evolve. The physical setting for the biodiversity of the South African coastal and offshore waters is mainly temperate continental shelf, slope and abyss in the South Atlantic and South-west Indian Oceans off the southern part of the continent of Africa. The geomorphology of this region has local effects on the ocean circulation, particularly effects on ocean currents and upwellings, which in turn affect the distribution of organisms and the environment in which they live.
Since Davis' ideas were being discredited other areas of research, like that of climatic geomorphology, were attacked by their perceived association to it. The notions of time, uplift, slope and drainage density evolution in the erosion cycle have been criticized. Further the validity of some whole concepts associated with the cycle of erosion have been questioned including stream grade, base level and most of all that of peneplains. Writing in 1971 geomorphologist Ronald Flemal summarized the situation as follows: :Currently geomorphologists are divided into three camps: those who still adhere to Davisian concepts, either in the original or a modified form; those who desire to replace Davisian ideas by a different cyclic erosional model; and those who reject cyclic erosion completely.
The Wilsons River floods regularly, and on occasion, has inundated Lismore. It's for this reason that many of Lismore's homes are built elevated, in a fashion known as hiset and why Lismore has extensive levee systems to protect the city from all but the worst floods. The frequency of flooding is due to several contributing factors. One is the relatively high rainfall in the headwaters of the system (The Rummery Park Rain Gauge is the Wettest in NSW)Australian Bureau of Meteorology Retrieved on 23 May 2011 and the unusual geomorphology which means that the River flows away from the sea for a significant distance then south after reaching Lismore before joining the Richmond River which eventually flows north east to the Tasman Sea.
From 1978 to 1990 he held a Junior Researcher position, then a Senior Researcher position and then worked as a Head of the Yalta Department All-Union Water Conservation Research Institute at the State Committee of Nature Protection of the USSR (Kharkov). From 1990 to 1992 he worked as a Head of the Yalta Department in the Sochi Research Centre “Recreation Territories Management and Tourism” at the USSR Academy of Sciences In 1984 he became a Kandidat of Geographical Sciences (Thesis “Interaction Models in the Slope Geomorphology”, defended in MSU, Research Advisor – Professor Y.G. Simonov). In 1998 he became a Doktor of Geographical Sciences (Thesis “Dynamics, Stability and Control over of the Marine Shore Eco Geosystems”, defended in Kharkov State University, Research Supervisor – Professor V.E. Nekos).
Sixteen sites within the area have had access to them restricted in order to protect their natural values and others have been identified as Important Bird Areas. Two have been given additional protection as Antarctic Specially Protected Areas – Litchfield Island (ASPA 113) and Biscoe Point (ASPA 139). The area contains diverse and accessible assemblages of terrestrial and marine flora and fauna which have been subject to long-term monitoring, with some datasets covering much of the last century, with intensive scientific interest beginning in the 1950s. Studies include monitoring of bird and seal populations, surveys of terrestrial and sub-tidal environments, investigations into the physiology, biochemistry, ecology and behaviour of birds, seals, terrestrial invertebrates and zooplankton, as well as oceanography, marine sedimentology and geomorphology.
Harp player from Keros, 2600 BC. National Archaeological Museum, Athens In 2007–2008, the same project identified and excavated a substantial Cycladic period settlement on the nearby island of Daskalio. A large area has been excavated, revealing a substantial building 16 metres long and 4 metres wide — the largest from this period in the Cyclades — within which was discovered the ‘Daskalio hoard’ comprising a chisel, an axe-adze and a shaft-hole axe of copper or bronze. In addition to excavation, survey of the islet showed that most of its surface — a total of 7000 square meters — was occupied during the Early Bronze Age, making this the largest site in the Cyclades. Specialist studies for the geomorphology, geology, petrology, ceramic petrology, metallurgy and environmental aspects (botanical and faunal remains, phytoliths) ensued.
There, he established the first genealogy, covering four generations, of a group of 302 Inughuit, the northernmost people on earth. He also implemented a planning of trends in order to avoid the risks of consanguinity (banning marriage up to the 5th degree). As a geomorphologist in the Great North of Greenland, he raised the map of the coast to 1:100 000 (topography, geomorphology of screes and nivation, sea ice). The map covers a 300 kilometre long and 3 kilometre wide region from Inglefield Land and the north of the Humboldt Glacier, to the south of Washington Land (Cape Jackson, 80° N). He discovered various fjords and unknown littorals, which he was authorized to name himself after French names, like the Paris Fjord, or after his Inuit travel companions such as the famous shaman, Uutaaq.
The Keilor cranium has been radiocarbon dated at between 12,000Peter Brown, The Keilor Cranium , Peter Brown's Australian and Asian Palaeoanthropology, Accessed 3 November 2008 and 14,700 years BP. Subsequent studies of the local geomorphology identified three terrace formations on the Maribyrnong River banks, which were linked to changes in sea level over the previous 150,000 years. In 1953, Edmund Dwen Gill calculated the age of the cranium to be about 14,700 years BP using radiocarbon dating and fluorine-phosphate analysis. Gallus excavated a hearth in 1971, from which charcoal was radiocarbon-dated to about 31,000 years BP, making Keilor one of the earliest sites of human habitation in Australia. Remains of extinct megafauna species within the site were assessed as being possibly as recent as 20,000 years ago, although dating of the bones is problematic.
He was responsible for the establishment of the Tanzania Extractive Industries Transparency Initiative TEITI in Tanzania since its inception in 2008 and is proud to consider TEITI as one of his legacies. As part of the TEITI working Group he acquired knowledge, skills and insights on the EITI processes and activities. Kafumu was also a kingpin on advising the Government to review the Mineral Policy of Tanzania, 1997 and the Mining Act of 1998 into the Mineral Policy of Tanzania of 2009 and the Mining Act of 2010 and Mining Regulations of 2010, statutes that brought bigger benefits of mining industry in Tanzania. From 2006 to date at different times he was a Part-time lecturer in geology and environmental geomorphology at the Sokoine University of Agriculture and the University of Dodoma.
NCED is building interdisciplinary Earth-surface science by integrating elements of geomorphology, ecology, hydrology, sedimentary geology, engineering, economics, and geochemistry. It is creating a predictive Earth-surface science by integrating the advances and approaches of theory, laboratory experiments, numerical modeling, and fieldwork NCED research is unified by a focus on channel networks and their surroundings. The center's three research initiatives (“Integrated Programs”) approach channel networks from a source- to-sink perspective, looking at watersheds (Watersheds), individual stream reaches (Streams), and depositional systems (Deltas). :In the Watersheds Integrated Program, NCED researchers work to develop quantitative expressions for the fundamental geomorphic and biological processes involved in landscape evolution, and combine that knowledge with digital topographic data to predict the locations of landslide hazards, large algal blooms, or other properties of interest.
Moreover, this area had the potential for a significant residential expansion, being suitable for the relocation of a large number of British nationals to the region. Prevailing climatic conditions and the regions' geomorphology allowed the establishment of flourishing European style settlements like Nairobi, Vila Pery, Vila Junqueiro, Porto Amélia, Lourenço Marques and Entebbe. The French settled the largest island of the Indian Ocean (and the fourth-largest globally), Madagascar, along with a group of smaller islands nearby, namely Réunion and the Comoros. Madagascar became part of the French colonial empire following two military campaigns against the Kingdom of Madagascar, which it initiated after persuading Britain to relinquish its interests in the island in exchange for control of Zanzibar off the coast of Tanganyika, an important island hub of the spices trade.
While the model has greatly aided soil science, and spatially explains generalized soil- environmental relationships on landscapes, the device—supremely attractive in its parsimony—has constrained pedologic interpretation because its genetic- interpretive domain is constrained by its broad factorial (landscape context) tenets. The model allows for a wide-ranging generalized assessment of soilscapes, and is useful in soil chronosequence work (Birkeland 1974, 1984) but the biodynamic soil processes that are largely responsible in producing stonelayers are absent at a highest theoretical (five factors) level. Once mapped and classified, soils become static elements, which—while societally useful, scientifically misrepresents their true biodynamic nature. In a proposal to heal such Occam's razor wounds, process biodynamics supported with appropriate genetic language has been advanced to augment the traditional five factors genetic principles in pedology and soil-geomorphology.
In terms of geology, Shen Kuo is one of the first naturalists to have formulated a theory of geomorphology. This was based on his observations of sedimentary uplift, soil erosion, deposition of silt, and marine fossils found in the Taihang Mountains, located hundreds of miles from the Pacific Ocean. He also formulated a theory of gradual climate change, after his observation of ancient petrified bamboos found in a preserved state underground near Yanzhou (modern Yan'an), in the dry northern climate of Shaanxi province. He formulated a hypothesis for the process of land formation: based on his observation of fossil shells in a geological stratum in a mountain hundreds of miles from the ocean, he inferred that the land was formed by erosion of the mountains and by deposition of silt.
On published geologic maps of the area, Sugarloaf Mountain is mapped as part of the Middendorf Formation, a sequence of sandstone, pebbly sandstone, sand, silt, and clay that are interpreted as fluvial (river) deposits that accumulated during the Cretaceous PeriodSwezey, C.S., Fitzwater, B.A., and Whittecar, G.R., 2016, Geology and geomorphology of the Carolina Sandhills, Chesterfield County, South Carolina, in: Gold, Structures, and Landforms in Central South Carolina (W.R. Doar III, ed.), Geological Society of America Field Guide 42, p. 9-36.. While much of the mountain is composed of unconsolidated to semi-consolidated beds of quartz-rich sand, silt, and clay, outcrops and boulders of iron-cemented, pebbly sandstone can be found both on the mountain-side and the immediate vicinity. The iron-rich cement holding these sandstones together likely precipitated from groundwater interactions.
Simons therefore does not consider Davis an adequate critic of Penck's work. Other factors detrimental to an understanding of Penck's ideas include his early death and his confusing writing style. Douglas Wilson Johnson, a coastal geomorphologist and staunch supporter of Davis, criticized Penck's theory harshly as: :“Penck’s conception that slope profiles are convex, plane, or concave according to the circumstances of the uplifting action, [as] one of the most fantastic errors ever introduced into geomorphology” Julius Büdel, a German geomorphologist working in the same areas as Penck in Southern Germany, provided alternative explanations in 1935 for some of the landforms Penck had dealt with.Mensching 1984 Geographer Allaoua Saadi remarks by 2013 that Penck's and Davis' ideas have become more compatible and even complementary since the advent of modern tectonic theory.
Watson's work was met with some early scepticism, such as from the historian Jeremy Johns in 1984. Johns argued that Watson's selection of 18 plants was "peculiar", since the banana, coconut, mango and shaddock were unimportant in the Islamic region at the time, detracting from the discussion of the staple crops. Johns further noted that the evidence of diffusion of crops was imperfect, that Watson made "too many minor slips and larger errors" such as getting dates wrong or claiming that a 1439 document was Norman, and had failed to make best use of the evidence that was available, such as of the decline of classical agriculture, or even to mention the changing geomorphology. Johns however concluded that "The hypothesis of an 'Abbasid agricultural revolution is challenging and may well prove useful".
Hills lectured at the university from 1932 to 1943 climbing the academic ranks from lecturer, senior lecturer to associate professor; he became a full professor and the Chair of the geology department in 1944, he held this position until 1971. He also involved in the university administration serving as Deputy Vice-Chancellor from 1962 to 1971. While at Melbourne his fields of research were broad encompassing Australian fossil fishes of the Upper Devonian and Cainozoic, physiography, hydrology, petrology and mineralogy of Victoria and economic geology. In addition to scientific papers and monographs, Hills produced three geology textbooks; Outlines of Structural Geology (first published in 1940), The Physiography of Victoria: an Introduction to Geomorphology (first published in 1940), Elements of Structural Geology (first published in 1963), each was reprinted into multiple editions.
According to the WWF scheme, the coastal waters of continental South Africa mostly lie within the marine realm of Temperate Southern Africa, with a part in the Western Indo-Pacific. The boundary between the Temperate Southern Africa and Western Indo-Pacific marine realms is near Lake St. Lucia, in northern KwaZulu-Natal, near the border with Mozambique. The marine biodiversity of South Africa is the variety of living organisms that live in the seas off the coast of South Africa. It includes genetic, species and ecosystems biodiversity in a range of habitats spread over a range of ecologically varied regions, influenced by the geomorphology of the seabed and circulation of major and local water masses, which distribute both living organisms and nutrients in complex and time-variable patterns.
With hurricane-force winds every third day on average, more than a hundred recorded deaths among visitors, and conspicuous krumholtz (dwarf, matted trees much like a carpet of bonsai trees), the climate on the upper reaches of Mount Washington has inspired the weather observatory on the peak to claim that the area has the "World's Worst Weather". In the flatter southwest corner of New Hampshire, the landmark Mount Monadnock has given its name to a class of earth-forms—a monadnock—signifying, in geomorphology, any isolated resistant peak rising from a less resistant eroded plain. Major rivers include the Merrimack River, which bisects the lower half of the state north–south and ends up in Newburyport, Massachusetts. Its tributaries include the Contoocook River, Pemigewasset River, and Winnipesaukee River.
In 1981, Australian Democrats Senator Don Chipp initiated a Senate inquiry into "the natural values of south-west Tasmania to Australia and the world" and "the federal responsibility in assisting Tasmania to preserve its wilderness areas of national and international importance". From early 1981, archaeologists uncovered evidence of human habitation dating from about 15,000 years before present in caves which would be flooded if the dam were to be built. The most significant cave had been rediscovered by geomorphology student Kevin Kieran in January 1977, and he first named it Fraser Cave by after the then Prime Minister, Malcolm Fraser, because ...we were trying to direct the attention of politicians to the area...'.AUSTRALIA, An Ice Age - Walk to Tasmania It was renamed Kutikina in mid-1982, as suggested by the Tasmanian Aboriginal Centre.
In 1932, he staged the first recorded East- to-West crossing of the Libyan Desert. His work in the field of Aeolian processes was the basis for the book The Physics of Blown Sand and Desert Dunes, establishing the discipline of aeolian geomorphology, combining field work observations, experiments and physical equations. His work has been used by United States' space agency NASA in its study of the terrain of the planet Mars, the Bagnold Dunes on Mars' surface being named after him by the organization. During the Second World War, he was a soldier in the British Army, in which he founded the behind-the-lines reconnaissance, espionage and raiding unit that was named the "Long Range Desert Group", serving as its first commanding officer in the North Africa Campaign.
Between the two world wars, "classical geography" stayed in the mold established by the Vidalian tradition. It was defended by an establishment that marginalized all attempts at epistemological renewal, to such an extent that after World War II the discipline was at the same stage where it had been left at Vidal's death. Arguably, his disciples were bound to a particular aspect of the master's thought and did not know how to deal with complexity and growth, and as a consequence the field of the discipline shrank. An immutable triad imposed itself on research and university studies: physical geography (Martonne, Baulig), regional geography (Blanchard, Cholley), and human geography (Brunhes, Demangeon, Sorre); in descending order of frequency and importance geomorphology, then rural geography, regional geography, and finally tropical geography.
It aimed to explain the cultural relations of this territory with its regional entourage as well as the interaction between Man and environment in the southern part of the plain from the Neolithic to the Middle Bronze II. The research was structured around three major research axis. The first dealt with the analysis of the ceramic material surveyed in the southern part of the plain in 1997 and 1999 in order to learn the technological, cultural and chronological aspects of this material. Through the parallels, it also aimed to sketch a model of the cultural contacts throughout the region. The second focused on the palaeo-environmental data in order to understand the paleoclimate of the region in general, and the plain in particular with its geomorphology during the mentioned periods.
Local, county, state, federal and private industry experts in engineering design, fluvial geomorphology and fisheries conservation are working together to protect important public infrastructure such as roads and commercial and residential developments, while maintaining, improving, restoring, or creating aquatic habitat. The sheer mass of the dolosse provides ballast for logs and slash ("wrack" or "rack" organic debris) to create a stable, complex habitat structure, all the while precluding the need for excessive, environmentally- invasive and costly excavation for their placement into substrate. Such ELJs are of a new, innovative design that are on the leading edge of engineering and science technologies in aiding the recovery of Pacific Northwest (particularly Endangered Species Act-listed) salmonids, while protecting important public and private works and thus helping to balance the needs of man and nature.
Numerous systems exist to classify streams according to their geomorphology. This preliminary assessment helps to understand the stream dynamics and determining the cause of the observed degradation to be addressed; it can also be used to determine the target state for the intended restoration work, especially since the "natural" or undisturbed state is sometimes no longer achievable due to various constraints. Two broad approaches to stream restoration have been defined in the past decades: form-based restoration and process-based restoration. Whereas the former focuses on the restoration of structural features and/or patterns considered to be characteristic of the target stream system, the latter is based on the restoration of hydrological and geomorphological processes (such as sediment transport or connectivity between the channel and the floodplain) to ensure a stream's resilience and ecological health.
Despite its popularity, form-based restoration has been criticized by the scientific community. Common criticisms are that the scale at which form-based restoration is often much smaller than the spatial and temporal scales of the processes that cause the observed problems and that the target state is frequently influenced by the social conception of what a stream should look like and does not necessarily take into account the stream's geomorphological context (e.g., meandering rivers tend to be viewed as more "natural" and more beautiful, whereas local conditions sometimes favour other patterns such as braided rivers). Numerous criticisms have also been directed at the NCD method by fluvial geomorphologists, who claim that the method is a "cookbook" approach sometimes used by practitioners that do not have sufficient knowledge of fluvial geomorphology, resulting in project failures.
C. Maurice Yonge, a marine invertebrate researcher, was encouraged to join a proposed expedition to Australia’s Great Barrier Reef in 1927. He was eventually appointed its leader. Twelve scientists including Yonge, his wife Dr Mattie Yonge who would act as medical officer, as well as Frederick Russell, a naturalist with the Marine Biological Association in Plymouth and his wife Gweneth, Dr Andrew Orr and Dr Sheina Marshall, naturalists at Millport Marine Laboratory, Dr Thomas Stephenson, lecturer in zoology at University of London and his wife Anne, Geoffrey Tandy a botanist with the Natural History Museum who would collect marine plants and animals joined the expedition. Thomas Stephenson with apparatus for photographing corals, Low Islands, Queensland, circa 1928 - C.M. Yonge (26544167848) Others included James Steers, lecturer in geomorphology who acted as the expedition’s surveyor.
The limestone karstic geomorphology of the bay was developed since Miocene, especially the cone-shaped hills (fengcong), or isolated high limestone karst towers (fenglin) with many remnants of old phreatic caves, old karstic foot caves, marine notch caves form magnificent limestone karst landforms as unique on the world. The Quaternary geology was developed through 5 cycles with the intercalation of marine and continental environments. The present Hạ Long Bay, in fact, appeared after the Middle Holocene maximum transgression, leaving ultimate zone of lateral undercutting in the limestone cliffs bearing many shells of oysters, having the 14C age as 2280 to >40,000 y. BP. Geological resources are abundant: anthracite, lignite, oil shale, petroleum, phosphate, limestone and cement additives, kaolin, silica sand, dolomite, quartzite of exogenous origin, and antimony, mercury of hydrothermal origin.
Flash floods induce severe impacts in both the built and the natural environment. Especially within urban areas, the effects of flash floods can be catastrophic and show extensive diversity, ranging from damages in buildings and infrastructure to impacts on vegetation, human lives and livestock. An impact severity scale is proposed in 2020 providing a coherent overview of the flash flood effects through the classification of impact types and severity and mapping their spatial extent in a continuous way across the floodplain. Depending on the affected elements, the flood effects are grouped into 4 categories: (i) impacts on built environment (ii) impacts on man-made mobile objects,(iii) impacts on the natural environment (including vegetation, agriculture, geomorphology, and pollution) and (iv) impacts on the human population (entrapments, injuries, fatalities).
With Shen's writings on fossils, geomorphology, and shifting geographical climates, he states in the following passages: > In the Zhi-ping reign period [1064–67 AD] a man of Zezhou was digging a well > in his garden, and unearthed something shaped like a squirming serpent, or > dragon. He was so frightened by it that he dared not touch it, but after > some time, seeing that it did not move, he examined it and found it to be > stone. The ignorant country people smashed it, but Zheng Boshun, who was > magistrate of Jincheng at the time, got hold of a large piece of it on which > scale-like markings were to be seen exactly like those on a living creature. > Thus a serpent or some kind of marine snake (chhen) had certainly been > turned to stone, as happens with the 'stone-crabs'.
The Codex Ephraemi Rescriptus, a Greek manuscript of the Bible from the 5th century, is a palimpsest. In textual studies, a palimpsest () is a manuscript page, either from a scroll or a book, from which the text has been scraped or washed off so that the page can be reused for another document. Pergamene (now known as parchment) was made of lamb, calf, or goat kid skin (best made in ancient Pergamon) and was expensive and not readily available, so in the interest of economy a pergamene often was re-used by scraping off the previous writing. In colloquial usage, the term palimpsest is also used in architecture, archaeology, and geomorphology to denote an object made or worked upon for one purpose and later reused for another, for example a monumental brass the reverse blank side of which has been re-engraved.
Geomorphology 35 (2000) 1. pp. 145–162 Tarn Eastern Byers Peninsula with Urvich Wall and Rotch Dome in the background; a carpet of Usnea antarctica lichen in the foreground Along with the extensive Byers Peninsula () forming the west extremity of Livingston, the ice-free part of the island includes some minor coastal areas at Cape Shirreff, Siddins Point, Hannah Point, Williams Point, Hurd Peninsula and Rozhen Peninsula, as well as slopes in the mountain ranges, and ridges and heights in eastern Livingston that are too precipitous to keep snow. Numerous meltwater streams flow in the ice-free areas during summer, extending from hundreds of meters up to 4.5 km. Byers Peninsula alone has more than 60 such streams and as many lakes, notably Midge Lake (587 by 112 m, or 642 by 122 yd), Limnopolar Lake and Basalt Lake.
Periodic Bedrock Ridges (PBRs) are features of the surface geomorphology of Mars and formerly unknown on Earth, first described in a paper in the Journal of Geological Research - Planets, in March 2012,Periodic bedrock ridges on Mars, David R. Montgomery, Joshua L. Bandfield, Scott K. Becker, JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 117, E03005, 12 PP., 2012 doi:10.1029/2011JE003970, accessed 28 March 2012 by Professor David R. Montgomery, Joshua L. Bandfield, and Scott K. Becker of the University of Washington. Evidence for sediment transport and erosion by wind is widespread over the surface of Mars today and was likely a major geomorphic process for much of its geological past. Although Martian surface features resembling aeolian dunes and ripples have been recognized since the Mariner and Viking missions, such features have been interpreted previously as active, indurated, or exhumed sedimentary forms.
Map of the Gemarkung of the German municipality Hasel in the Grand Duchy of Baden in 1904, showing a proposed land swap between the local Domänenjagdbezirk (roughly: state hunting district) and the Gemeindejagdbezirk (municipal hunting district) A Gemarkung (also Markung, in Switzerland also Gemarchen, in Austria Katastralgemeinde) is the entirety of all land plots of a specific municipality recorded in the cadastre in the countries of Germany, Austria and Switzerland. Gemarkung registers record the parcels' location, usage and geomorphology and the like qualities, however, the rights to the land (as property, or collateral liened by a mortgage) are kept in the Grundbuch (land register). A Gemarkung is made up of a number of, usually contiguous, plots of urban (Grundstücke) or rural land (Flurstücke). Between the levels of Flurstück and Gemarkung is often found the level of Flur, usually a tract of open land or forest.
The payload would provide in-situ sampling, high-resolution imaging and radio science measurements from multiple flybys of Enceladus and Titan using a solar-electric powered spacecraft in orbit around Saturn. The two main instruments proposed are the Ion and Neutral Gas Mass Spectrometer (INMS) and the Enceladus Icy Jet Analyzer (ENIJA); these high resolution mass spectrometers would provide the data needed to discern the subtle details of the aqueous environment of Enceladus from plume sampling and of the complex pre-biotic chemistry occurring in Titan's atmosphere. The Titan Imaging and Geology, Enceladus Reconnaissance (TIGER) mid-wave infrared camera would map thermal emission from the plumes and Enceladus' tiger stripes at meter scales and investigate Titan's geomorphology at 50–100 m resolution. The Radio Science Experiment (RSE) measurements would provide constraints on the ice shell structure and the properties of the internal oceans of Enceladus and Titan.
His research, to which he devoted many years of his life, solved the cardinal problems of anthropology of the contemporary population of the Caucasus; the results of his investigations became widely known in the scientific world. He was a born scientist, and, owing to his exceptional purposefulness, his numerous works covered almost all the geographical problems of Georgia: geomorphology, cartography, the geographical distribution of the population, problems dealing with various peculiarities of the land and its people, and the varied terrain of the country; neither did the history of geography of Georgia escape his attention. The theoretical works of Javakhishvili are a significant contribution to Soviet geographical science; among these are publications devoted to the structure of this science, to the interrelations between sciences composing general geography and to their links with adjacent sciences, making part of the geography of the Earth.Kipiani S., Georgian State (Soviet) Encyclopedia, 1987.
Versatility, breadth of learning, non-stop working ability, great talent displayed in Levan Maruashvili's diverse scientific interests made the basis of his creative work. In 1959, for the first time he began investigation of periglacial forms, defined their high altitude line and peculiarities of spreading of the major forms of peri-glacial formations on the South-Georgian volcanic upland in the Central Caucasus. In the scientific activity of Levan Maruashvili there may be singled out the following basic branches of Geography, in the study of which be made great contributions: Geomorphology of Georgia, Paleogeography of Georgia and the Caucasus (Neogene-Quaternary period), Regional physical Geography of Georgia and the Caucasus, Karstology and speleology, History of geographical knowledge and travels, Rustvelology and Mountaineering. In 1975 and 1980, for the first time there was published in Georgian a three-volume work entitled "Physical Geography of the Caucasus".
The mountain range is crossed by the Alta Via n. 4 path and from the equipped Alberto Bonacossa path, which starts from the southern shore of the lake and reaches the Tre Cime di Lavaredo. The particular geomorphology that distinguishes and so deeply characterizes the Cadini di Misurina, however, allows to cross the group by various lines so that, going up and down from their forks, it becomes possible to enjoy the dolomitic paradise that surrounds them. The equipped path Giovanni Durissini allows for example to complete the complete tour of the branch of San Lucano. It is a ring route, starting at the Fonda-Savio refuge (2,367 m), which runs in sequence the Torre fork (2,400 m), the Sabbee fork (2,440 m), the Cadin Deserto fork (2,400 m), the Cristina fork, the de la Neve fork (2,471 m) and lastly the Nevaio fork (2,620 m), with a total height difference of about 1,000 m.
The geomorphology of Northern Asia in general is imperfectly known, although the deposits and mountain ranges are well known. To compensate for new sea floor having been created in the Siberian basin, the whole of the Asian Plate has pivoted about a point in the New Siberian Islands, causing compression in the Verkhoyansk mountains, which were formed along the eastern margin of the Angara Shield by tectonic uplift during the Mesozoic Era. There is a southern boundary to this across the northern margin of the Alpine folds of Afghanistan, India, Nepal, and Bhutan, which at the east of Brahmaputra turns to run south towards the Bay of Bengal along the line of the Naga hills and the Arakan Yoma, continues around Indonesia, and follows the edge of the continental shelf along the eastern seaboard of China. The Eurasian Plate and the North American Plate meet across the neck of Alaska, following the line of the Aleutian Trench, rather than meeting at the Bering Straits.
Throughout his career Mackin was a guest lecturer at many universities, and was the Distinguished Lecturer for the American Association of Petroleum Geologists in 1953 and National Lecturer for Sigma Xi in 1963. Mackin was a member of the National Academy of Sciences, the Geological Society of America (Council, 1950-1953; chairman of Cordilleran Section, 1950), the Society of Economic Geologists, the American Geophysical Union, the American Association of Petroleum Geologists, the American Association for the Advancement of Science, and Sigma Xi. Mackin died on August 12, 1968, while preparing to serve as delegate of the U.S. National Committee on Geology to the International Geological Congress to be held in Prague later in 1968. The University of Texas, where he taught, has an endowment benefiting geosciences, the J. Hoover Mackin Memorial Scholarship Fund. The Geological Society of America also offers a memorial scholarship for students in quaternary geology and geomorphology from the J. Hoover Mackin Award Fund.
Bill Breed was a Fulbright Scholar at Canterbury University in Christchurch, New Zealand to study geomorphology in 1957-58.Canton Repository, March 12, 1957 Bill Breed was a protégé of Edwin D. McKee. Breed was Curator of Geology (1960–78), Head, Geology Department (1978–81) at the Museum of Northern Arizona in Flagstaff, Arizona. In 1969, Breed and Edwin H. Colbert were two of the four vertebrate paleontologists in Antarctica who helped solidify the acceptance of continental drift theory, by finding a 220-million- year-old fossil of a Lystrosaurus. In the 1970s, Breed completed numerous publications on the Grand Canyon, including a geologic cross section map of the Grand Canyon, San Francisco Peaks and Verde Valley; and the book, Geology of the Grand Canyon.Arizona Daily Sun, January 24, 2013, A2; A species of Dilophosaurus, (D. breedorum), discovered by Sam Welles in Arizona in 1964 was named after William J. Breed and his wife at the time Carol S. Breed.Welles, S. P. (1984).
The Whale Islet, located in the northern coast, adjacent to the Ponta da Baraca Lighthouse The main tower of the lighthouse The General Plan for Lighthouses of 1883, documents the necessity of installing a lighthouse on top of Pico Negro, a volcanic cone located to the southeast of Ponta da Barca. Difficulties in accessibility and problems with the geomorphology of the area brought the planners to the conclusion that Ponta da Barca would be a more suitable alternative (although the interposition of Pico Negro did not permit some visibility from Ponta da Barca). The new selection, was acceptable to the Comissão dos Faróis e Balizas (Commission on Lighthouses and Beacons), which concluded in 1902 that although the economically small lighthouse would be able to support ships travelling from the north. Although included in the 1883 Lighthouse Plan, and its location selected in 1902, it was not until 1927 when the equipment, optics and lantern were purchased from France (for 804,200 francs).
Forensic geology is the study of evidence relating to minerals, oil, petroleum, and other materials found in the Earth, used to answer questions raised by the legal system. In 1975, Ray Murray and fellow Rutgers University professor John Tedrow published Forensic Geology.Murray, Raymond C. and Tedrow, John C. F. (1975) Forensic Geology: Earth sciences and criminal investigation Rutgers University Press, New Brunswick, New Jersey, ; second edition 1992, Prentice Hall, Englewood Cliffs, New Jersey, ; replaced by Murray, Raymond C. (2004) Evidence from the Earth: Forensic geology and criminal investigation Mountain Press Publications, Missoula, Montana, More recently, in 2008, Alastair Ruffell and Jennifer McKinley, both of Queen's University Belfast, UK, published GeoforensicsRuffell, Alastair and McKinley, Jennifer (2008) Geoforensics John Wiley and Sons, West Sussex, England, a book that focuses more on the use of geomorphology and geophysics for searches. In 2012, Elisa Bergslien, at SUNY Buffalo State, published a general textbook on the topic, An Introduction to Forensic Geoscience.
Geological maps of County Donegal show rock alignments running south-west to north east across the Fanad peninsula. The underlying rock in the peninsula is mostly of Dalradian meta-sedimentary rocks, which have been exposed by weathering and erosion over the millennia There are areas of Granodiorite igneous rocks across the northern end of the peninsula from Ballywhoriskey to Fanad Head, but the greater part of Fanad consist of Middle-Dalradian Quartzite and some Pellite rocks with local occurrences of Schists and Tillites – the latter mostly concentrated around the northern inlet of Mulroy Bay.As per maps and text of Chapter One – Geology and Geomorphology by Moore, Cooper, Dunlop and Jackson, from Lough Swilly – A Living Landscape, Ed. Andrew Cooper (2011) The cliffs around Fanad Head are of exposed Grandiorite, whereas the higher ground running south from Fanad Head to Portsalon is a band of Quartzite. Knockalla Mountain is also formed of Quartzite.
Du Yu (222–285) a Chinese Jin Dynasty officer, believed that the land of hills would eventually be leveled into valleys and valleys would gradually rise to form hills.Temple (1986), 169. The Daoist alchemist Ge Hong (284–364) wrote of the legendary immortal Magu; in a written dialogue by Ge, Ma Gu described how what was once the Eastern Sea (i.e. East China Sea) had transformed into solid land where mulberry trees grew, and would one day be filled with mountains and dry, dusty lands. The later Persian Muslim scholar Abū Rayhān al-Bīrūnī (973–1048) hypothesized that India was once covered by the Indian Ocean while observing rock formations at the mouths of rivers.Salam (1984), 179–213. Li Kan(1244–1320); using evidence of fossilized bamboo within China's dry northwestern climate zone, Shen Kuo hypothesized that climates naturally shifted geographically over time. It was Shen Kuo who formulated a hypothesis about the process of land formation (geomorphology) based upon several observations as evidence.
The timing of the mission was important, as it would have passed Pluto shortly before its atmosphere froze, which it was thought to do for a considerable part of its orbit. The mission's main objectives would have been to map Pluto's surface and examine the double system's geology and geomorphology, as well as determining the composition of Pluto's atmosphere. This last task would have been considerably more difficult after the start of atmospheric freezing. Scientific equipment on board would have included visible light imaging systems, infrared and ultraviolet spectrometers, and an ultrastable oscillator (USO) for use in a radio occultation experiment. The spacecraft was to have been a simple hexagonal prism shaped structure weighing some 220 kg (485 lb), powered by radioisotope thermal generators (RTGs) similar to those used on the Galileo and Cassini missions. On-board control and data collection would have been maintained by a 1.5 MIPS RISC-based computer system capable of processing data at 5 Mbit/s.
Geology of south-eastern England. The Ashdown Sands and Wadhurst Clay is in lime green (9a); the Low Weald, darker green (9). Chalk Downs, pale green (6) Geological section from north to south The geology of East Sussex is defined by the Weald–Artois anticline, a wide and long fold within which caused the arching up of the chalk into a broad dome within the middle Miocene, which has subsequently been eroded to reveal a lower Cretaceous to Upper Jurassic stratigraphy. East Sussex is best known geologically for the identification of the first dinosaur by Gideon Mantell, near Cuckfield, to the famous hoax of the Piltdown man near Uckfield. The county’s chalk has provided a world-class stratigraphic marker giving a great deal of detail in Cretaceous Chalk palaeoecology and palaeontology while in the east of the county on the Kentish border the Dungeness Foreland is important for the study of geomorphology and Holocene sea level fluctuations.
Coelacanth off Pumula on the KwaZulu-Natal South Coast, South Africa, on 22 November 2019Kelps Laminaria pallida (top) and Ecklonia maxima (below) The Marine biodiversity of South Africa is the variety of living organisms that live in the seas off the coast of South Africa. It includes genetic, species and ecosystems biodiversity in a range of habitats spread over a range of ecologically varied regions, influenced by the geomorphology of the seabed and circulation of major and local water masses, which distribute both living organisms and nutrients in complex and time-variable patterns. South Africa has a wide range of marine diversity with coastline in three oceans, two major current systems, major ocean frontal systems and benthic topography extending to a maximum depth of 5 700 m. There are 179 defined marine ecosystem types, 150 of them around South Africa and 29 around the sub-Antarctic territory of the Prince Edward Islands.
Another method of ensuring the ecological health of streams while limiting impacts on human infrastructures is to delineate a corridor within which the stream is expected to migrate over time. This method is based on the concept of minimum intervention within this corridor, whose limits should be determined based on the stream's hydrology and geomorphology. Although this concept is often restricted to the lateral mobility of streams (related to bank erosion), some systems also integrate the space necessary for floods of various return periods. This concept has been developed and adapted in various countries around the world, resulting in the notion of "stream corridor" or "river corridor" in the U.S.A., "room for the river" in the Netherlands, "espace de liberté" ("freedom space") in France (where the concept of "erodible corridor" is also used) and Québec (Canada), "espace réservé aux eaux" ("space reserved for water(courses)") in Switzerland, "fascia di pertinenza fluviale" in Italy, "fluvial territory" in Spain and "making space for water" in the United Kingdom.
It focused primarily on the topography of the land, along with the agricultural, economic and commercial products of each region in China's southern provinces. The polymath Chinese scientist Shen Kuo (1031–1095) devoted a significant amount of his written work to geography, as well as a hypothesis of land formation (geomorphology) due to the evidence of marine fossils found far inland, along with bamboo fossils found underground in a region far from where bamboo was suitable to grow. The 14th-century Yuan dynasty geographer Na-xin wrote a treatise of archeological topography of all the regions north of the Yellow River, in his book He Shuo Fang Gu Ji. The Ming dynasty geographer Xu Xiake (1587–1641) traveled throughout the provinces of China (often on foot) to write his enormous geographical and topographical treatise, documenting various details of his travels, such as the locations of small gorges, or mineral beds such as mica schists.
These aqueous environments are believed to preserve evidence of paleo-habitability and potentially, earth-like microorganisms capable of breaking down rocks and minerals for energy, known as chemolithoautotrophs. Until Curiosity had arrived on Mars, all surface age dating of Mars had been through relative techniques using geomorphology and crater counting methods in order to determine an estimated age of the rock layering. The Mars Science Laboratory team used the rover to collect samples from the mudstone at Yellowknife bay then, using the mass spectrometer, from the Sample Analysis at Mars (SAM) instrument package measured argon isotopes for an absolute radiometric date of the rock member, and an approximate age of its exposure to the surface. The age of the lake bed rock was dated to 4 billion years old, and exposed by wind erosion between 30 and 110 million years ago, giving us the first absolute age of a rock on another planet.
The island is characterized by its gentle relief in the northern half of the island and a mountain range in the southern half composed of several phonolitic peaks with altitudes between where there is a patch of primary rainforest. The difference in geomorphology and terrain between the two sides, results in differentiated bioclimatology, has influence in the distribution of major types of ecosystems of the island, such as lotic (river) systems in the area of the massif and its valleys and lentic (lake) systems in the northern plains area. The biosphere reserve is home to great biodiversity in terrestrial as well as in marine ecosystems, with high rates of endemism in many groups of organisms, especially vascular plants, molluscs, insects, birds, reptiles and bats. It is part of the biodiversity hotspot of tropical forests of West Africa, containing a wide range of plant communities and habitats of high international importance such as primary tropical forests, forest shade, palm trees and lowland riparian habitats.
High-resolution digital elevation maps generated by airborne and stationary lidar have led to significant advances in geomorphology (the branch of geoscience concerned with the origin and evolution of the Earth surface topography). The lidar abilities to detect subtle topographic features such as river terraces and river channel banks, to measure the land-surface elevation beneath the vegetation canopy, to better resolve spatial derivatives of elevation, and to detect elevation changes between repeat surveys have enabled many novel studies of the physical and chemical processes that shape landscapes. In 2005 the Tour Ronde in the Mont Blanc massif became the first high alpine mountain on which lidar was employed to monitor the increasing occurrence of severe rock-fall over large rock faces allegedly caused by climate change and degradation of permafrost at high altitude. Lidar is also used in structural geology and geophysics as a combination between airborne lidar and GPS for the detection and study of faults, for measuring uplift.
This only alleviated the problems which were finally solved in the 1930s with the construction of a water pumping station.La Bonifica tra Basso Sile e LagunaArtificial fluvial diversions in the mainland of the Lagoon of Venice during the 16th and 17th centuries inferred by historical cartography analysis, Geomorphologie, Vol 18, No 2, 2012 : Alluvial geomorphology in Italy To the west of Mestre, the River Brenta and other nearby watercourses caused floods and silting in the central area of the lagoon which led to disruptions in that part of the mainland countryside and obstructed navigation on the watercourses which connected Venice with the mainland. To counter this, between the 14th century and the early 16th century, the Republic of Venice diverted the waters of this fluvial system, especially the Brenta, with a series of canals. After a number of ineffective interventions two long canals were created. Between 1489 and 1507 the Brenta Nova canal was dug to divert the Brenta away from its original mouth at Fusina, near Venice, to Conche, in the southern lagoon.
By the end of the 19th Century it was generally accepted that the cause of folding and faults was lateral compression that resulted from a shrinking Earth caused by its gradual cooling.Burt, T. P. et al. (eds.) (2008) The History of the Study of Landforms: Quaternary and recent processes and form (1890–1965) and the mid-century revolution.

The deformation it most likely caused by magma intruding into the crust from the Altiplano-Puna magmatic body, with the intrusion taking place at a level below that where magma accumulated prior to past eruptions of Uturuncu. It has been described as an ascending diapir or as a growing pluton although an alternative theory holds the ascent of volatiles along a magma column reaching to the Altiplano-Puna magmatic body as responsible for the surface deformation; in that case the uplift might reverse over time. Such surface uplift has been observed at other volcanic centres in the Central Volcanic Zone but on global scale it is unusual both for its long duration and its spatial extent, and in the case of Uturuncu demonstrates the continuing activity of the Altiplano-Puna magmatic body. In addition, there is no evidence for a net uplift in the geomorphology of the region, and findings in the terrain around Uturuncu indicate that this uplift certainly began less than 1,000 years ago and likely also less than 100 years ago.
The peat outcrops on the foreshore at White Strand north of Rathmullan contain the remainder of trees which were submerged by the advance of the sea in this area.As per maps and text of Chapter One – Geology and Geomorphology by Moore, Cooper, Dunlop and Jackson, from Lough Swilly – A Living Landscape, Ed. Andrew Cooper (2011) Many of the beaches on the Fanad shoreline were formed at this time by glacial deposits which were subsequently reworked by the actions of waves and currents. In common with much of the rest of Ireland, the post-glacial landscape gradually changed with rises in temperature from open tundra to one dominated by forests of pine, oak, alder, hazel and birch, with breaks in the canopy on the edges of the intervening expanses of lake and bog. This was probably the landscape which greeted the earliest settlers who ventured along the coastline in the late Mesolithic Period, possibly about 5,000 BC. There is archaeological evidence of human occupation of coastal areas of Inishowen at DunaffRef.
The district is composed of two distinct regions described in terms of its geographic differences: the northern areas, with the higher altitudes constitute the Terra Fria Transmontana (Cold lands), and the Alto Trás-os-Montes, where the landscape is dominated gentler slopes of the plateau; and the southern areas, the Terra Quente Trasmontana (Hot Lands), where the climate is milder, marked by the valleys of the Douro River and its tributaries. Its area allows a wide diversity of landscapes, and the district is known for its climatic differences (nine months of winter and three of heat), its rugged geomorphology, an aging population and urban to rural migration of its residents over time. It is the Douro River that characterizes the geography, dividing the borders within the district, its southern frontier and extreme northeast borders with Spain. It is in the Douro valley that the lowlands of the district are primarily located, although almost all are 400 metres above sea level, with the exception of the municipality of Mirandela and its rivers.
Haïdar-Boustani, Maya., Neo-lithics 01/07 - 2007 The geography and geomorphology of this alluvial filled, tectonic depression has been explored as part of a wider investigation of the area by various research bodies.

Log jam in Goodell Creek, Washington Log jams alter flow hydraulics by diverting flow towards the bed or banks, increasing flow resistance and creating upstream pools, diverting flow onto the floodplain and damming the channel causing water to spill over the structure. These altered channel hydraulics change local patterns of erosion and deposition, which can create greater variety in local geomorphology and thus create provision and variety of habitat for instream living organisms. The formation of a log jam against one bank typically concentrates flow in the wood-free portion of the channel, increasing velocity through this section and promoting scour of the riverbed, the formation of channel-spanning log jams can lead to the formation of an upstream pool, water spilling over the structure generating a "plunge pool" immediately downstream. The hydraulic and geomorphological effects of log jams are highly dependent on the slope of the river (and thus the potential power of the stream); in steep channels, log jams tend to form channel-spanning steplike structures with an associated downstream scour pool, whereas, in large lowland rivers with low slopes, log jams tend to be partial structures primarily acting to deflect flow with minimal geomorphological change.
While the great inlet of the Bay of Kotor winds deep into the High-Karst zone of Mt. Orjen, Mediterranean climate penetrates far inland. Profound mixtures of species from more than one climatic zone and in addition endemic and stenoendemic species and special vegetation types with marked transitional vegetation units restricted exclusively to ecotons of humid (Csa) subtropical and hyper humid oceanic- (Cfs) climates are especially notable. Mediterranean cyclones and sirocco storms are accountable for the heavy precipitation (up to 5000 mm/m2 at Crkvice, 940 m AMSL) that feeds the luxuriant and hyper-humid type of eastern Mediterranean vegetation comparable to colchidia-hyrcanian formations of the Caucasus and Asia Minor in the exceptionally damp and mild climate of the Montenegrin coast. While humidity generally increases with altitude, the vegetational structure of transects on Orjen varies through a combination of ranges of warmth and humidity where altitude, exposition, geomorphology and pedology correlate with specific alliances in the vegetation. At coast level at Risan with up to 3500 mm/m² precipitation per year the perhumid eumediterranean climate variant is established (Cs’’a climate; s’’= double winter rain season.
Precision GPS- measurements are carried out virtually all lines on the basis of the differential method using a so -called GPS- base station (this method is called by the relative kinematics ). In this case, at the time of measurement one satellite receiver (base station) is always in a known location, and the other - moving, fixing the position of recordable points. Thus, in 2012 the Republican Center of Seismic Service with ANAS department was created, \" Geodynamics \" under the direction of PhD Kazimov I.E. On the territory were established 24 GPS stations (Trimble). For the first time the world\'s first GPS station was installed at a depth of 8324 meters in the territory of the Republic of Azerbaijan in Saatly region Given the geomorphology, geotectonic, given the topography and the influence of external factors in the various regions of the country have been chosen place for the construction of new GPS stations. This new monitoring system consists of the 21st GPS stations of the company «Trimble» ( USA) and one central station in Baku, where the mode «online» receives all the data from all the regions where they were installed stations ( Fig.
Rudwick The Meaning of Fossils p. 39 In 1027, the Persian naturalist, Ibn Sina (known as Avicenna in Europe), proposed an explanation of how the stoniness of fossils was caused in The Book of Healing. He modified an idea of Aristotle's, which explained it in terms of vaporous exhalations. Ibn Sina modified this into the theory of petrifying fluids (succus lapidificatus), which was elaborated on by Albert of Saxony in the 14th century and was accepted in some form by most naturalists by the 16th century.Rudwick The Meaning of Fossils p. 24 Shen Kuo () (1031–1095) of the Song Dynasty used marine fossils found in the Taihang Mountains to infer the existence of geological processes such as geomorphology and the shifting of seashores over time.Shen Kuo,Mengxi Bitan (梦溪笔谈; Dream Pool Essays) (1088) Using his observation of preserved petrified bamboos found underground in Yan'an, Shanbei region, Shaanxi province, he argued for a theory of gradual climate change, since Shaanxi was part of a dry climate zone that did not support a habitat for the growth of bamboos.Needham, Volume 3, p. 614.
Rose was an invited speaker at the Second Symposium on the Geology of Libya, at Tripoli, in 1978; helped lead fieldwork for petroleum consultancies in Libya in 1978 and Oman in 1982; was briefly a visiting lecturer at the University of El Minia, Egypt, in 1985; and under the auspices of the British Council, a visiting lecturer and D-ès-Sc examiner at the University of Tunis, Tunisia, in 1987. Rose's research interests in limestone stratigraphy and palaeoenvironments were focused for some years on the Maltese islands (he was co-author of a Field Guide to Mid-Tertiary Carbonate Facies of Malta published by the Palaeontological Association for a field trip for which he was convening leader, in 1981), but subsequently and even more productively on Gibraltar. From 1989 he has, as sole or joint author, generated over 40 publications on the geology of this famous ‘Rock’, including the first large- scale printed map of the peninsula and an accompanying field guide, plus papers on topics including the stratigraphy, depositional palaeoenvironments, dolomitisation, brachiopod palaeontology, micropalaeontology, hydrogeology, and tunnelling excavation of the Jurassic ‘Gibraltar Limestone’, aspects of its Quaternary geomorphology and sedimentary cover, and the history of research by British pioneers of Gibraltarian geology.
In 2017 or later, Hussain Ibrahim Qutrib, an Associate Professor of Geomorphology at the King Faisal Center for Research and Islamic Studies, wrote an article about the demographic changes that have occurred in "Useful Syria" as a result of the Syrian Civil War. Specifically, Qutrib defined "Useful Syria" in a way similar to how Syrian President Bashar al-Assad defined this term in early 2016--as in, including the Syrian governorates of Damascus, Rif Dimashq, Homs, Hama, Latakia, and Tartus. Qutrib pointed out that these six governorates contained 46% of Syria's total population at the end of 2011--as in, 9.8 million people out of a total Syrian population of almost 21.4 million people at that point in time. Qutrib points out that, at the end of 2011, the demographics of "Useful Syria" were 69% Sunni, 21% Alawite (which is an offshot of Shi'a Islam), 1% Shi'a, 1% Druze, 2% Ismaili, and 6% Christian. In contrast, by 2016, the population of "Useful Syria" fell from 9.8 million to 7.6 million but its demographics have also significantly changed in the intervening five years; in 2016, "Useful Syria" was just 52% Sunni, 24% Alawite, 13% Shi'a, 1% Druze, 3% Ismaili, and 7% Christian--with the main change being the explosive growth of the Shi'a population in "Useful Syria" between 2011 and 2016.
