Breakwaters are subject to damage and overtopping in severe storms. The dissipation of energy and relative calm water created in the lee of the breakwaters often encourage accretion of sediment (as per the design of the breakwater scheme). However, this can lead to excessive salient build up, resulting in tombolo formation, which reduces longshore drift shoreward of the breakwaters. This trapping of sediment can cause adverse effects down-drift of the breakwaters, leading to beach sediment starvation and increased coastal erosion.

This may then lead to further engineering protection being needed down-drift of the breakwater development. Salient formations as a result of breakwaters are a function of the distance the breakwaters are built from the coast, the direction at which the wave hits the breakwater, and the angle at which the breakwater is built (relative to the coast). Of these three, the angle at which the breakwater is built is most important in the engineered formation of salients. The angle at which the breakwater is built determines the new direction of the waves (after they've hit the breakwaters), and in turn the direction that sediment will flow and accumulate over time.

Designed by engineer James Meadows Rendel, the work carried out under civil engineer John Towlerton Leather, with Rendel as engineer in chief (until his death in 1856), and John Coode as resident engineer. During 1848, HM Prison Portland was established to provide convict labour to quarry the stone needed to construct the breakwaters and the harbour defences. Known as the Admiralty Quarries, they provided 10,000 tons of stone per week. The breakwaters were declared complete by HRH Edward the Prince of Wales on 10 August 1872.

There are two main types of offshore breakwater (also called detached breakwater): single and multiple. Single, as the name suggests, means the breakwater consists of one unbroken barrier, while multiple breakwaters (in numbers anywhere from two to twenty) are positioned with gaps in between (). The length of the gap is largely governed by the interacting wavelengths. Breakwaters may be either fixed or floating, and impermeable or permeable to allow sediment transfer shoreward of the structures, the choice depending on tidal range and water depth.

The dock entrance is on the east side of Barry Island, which protects it from winds from the west and southwest. Two rubble breakwaters with six ton stone blocks on the seaward side protect the entrance from winds from other directions. Given the height of the tides, the breakwaters are substantial structures, high at the deepest part, and wide at the base. The Barry Docks West Breakwater Light, a white cast-iron tower at the head of the west breakwater, was built in 1890.

The San Pedro Breakwater was constructed between 1899 and 1911 at San Pedro; the Middle Breakwater was completed over the next twenty-five years, and the Long Beach Breakwater was finished after World War II.gazettes.com, Port History: From Swamp To International Trade Hub, By Jonathan Van Dyke, Staff Writer, June 22, 2011 The breakwaters provided the ports considerable protection in the 1939 California tropical storm.

Rubble mound breakwaters use structural voids to dissipate the wave energy. Rubble mound breakwaters consist of piles of stones more or less sorted according to their unit weight: smaller stones for the core and larger stones as an armour layer protecting the core from wave attack. Rock or concrete armour units on the outside of the structure absorb most of the energy, while gravels or sands prevent the wave energy's continuing through the breakwater core. The slopes of the revetment are typically between 1:1 and 1:2, depending upon the materials used.

The National Diet held a special meeting in November to address issues regarding the typhoon's aftermath. Following the disaster, a marked increase in actions and countermeasures to storm surge events and typhoons were enacted. Throughout Osaka, construction of breakwaters and embankments alleviated flood risks in coastal communities, reducing the risk of life from roughly 10−3 to 10−7 by the time of Typhoon Nancy in 1961. Before the onset of World War II, total anti-flood construction in Osaka spanned ; this included along rivers and canals, of levees, and of breakwaters.

The Living Breakwaters is a project in Staten Island that uses Oysters or oyster-tecture to protect from storm surge, increase biodiversity, clean water, and create educational opportunities. Living Breakwaters will work under the guidance of the Billion Oyster Project, a company that has done similar projects many times all over the shores of the world. This project is in part funded by the federal Department of Housing and Urban Development. They have contributed $60 million partly for the purpose of disaster recovery, but also to prevent the same disaster in the future.

A line of Phoenix elements forming a breakwater at Arromanches The Phoenix breakwaters were a set of reinforced concrete caissons built as part of the artificial Mulberry harbours that were assembled as part of the follow-up to the Normandy landings during World War II. They were constructed by civil engineering contractors around the coast of Britain. They were collected at Dungeness and Selsey, and then towed by tugboats across the English Channel and sunk to form the Mulberry harbour breakwaters replacing the initial "Gooseberry" block ships. Further caisson were added in the autumn of 1944 to reinforce the existing structure to cope with the harbour continuing in use longer than planned. A pair of Phoenixes at Portland Harbour Several Phoenix breakwaters still exist in Britain: two are part of the harbour off Castletown at Portland Harbour and two can be dived in less than 10 metres of water off Pagham.

From 1989 to 1992, over 50 breakwaters were built along the western and northern shore of the peninsula to help control erosion. In 1997 the park's Important Bird Area (IBA) was one of the first 73 IBAs established in Pennsylvania.

Submerged breakwaters have historically been used for coastal protection. If an offshore structure is specifically designed for both the improvement of a recreational resource (i.e. wave riding) and coastal protection or stabilization, it can be classified as a multi-purpose reef.

In September 2012, state contractors broke ground on a major $17-million restoration project. Over two years the Department of Conservation and Recreation plans to repair the badly eroded shoreline by adding 450,000 cubic yards of sand and gravel. Since the construction of a series of offshore breakwaters known locally as "the Five Sisters" in the 1930s, a significant volume of sediment has accumulated behind the Five Sisters creating a large tombolo. These offshore breakwaters have also contributed to increased erosion on the southern portion of Winthrop Beach, leaving the seawall, Winthrop Shore Drive and adjacent residences vulnerable to storm damage.

Caisson breakwaters typically have vertical sides and are usually erected where it is desirable to berth one or more vessels on the inner face of the breakwater. They use the mass of the caisson and the fill within it to resist the overturning forces applied by waves hitting them. They are relatively expensive to construct in shallow water, but in deeper sites they can offer a significant saving over revetment breakwaters. An additional rubble mound is sometimes placed in front of the vertical structure in order to absorb wave energy and thus reduce wave reflection and horizontal wave pressure on the vertical wall.

Located on the harbour breakwaters of Büsum are two other lights. On the west mole is a 9-metre high red tower which displays an occulting red light. The east mole has a similar tower, painted green that displays an occulting green light.

In 1912, a new square steel pyramidal tower was constructed on the North Pier. The light was electrified in 1919. In the 1920s, construction began on a pair of concrete breakwaters at the harbor entrance. Construction was complete by the early 1930s.

The Phoenixes, once refloated, were towed across the channel to form the "Mulberry" harbour breakwaters together with the "Gooseberry" block ships. Ellsberg rode one of the concrete caissons to Normandy; once there he helped unsnarl wrecked landing craft and vehicles on the beach.

The structural approach attempts to prevent erosion. Armoring involves building revetments, seawalls, detached breakwaters, groins, etc. Structures that run parallel to the shore (seawalls or revetments) prevent erosion. While this protects structures, it doesn't protect the beach that is outside the wall.

Many surviving bridges in mid-Cork are originally constructed of stone, arched in shape, and late eighteenth or early nineteenth century in date, and often contain semi-circular arches and pointed breakwaters. Aghabullogue Bridge, however, would appear to be of a later construction date.

33 The lighthouse is connected with the port's shoreline by a long stone causeway and jetty, which protect the port from the southern high seas. The port is protected on the east by huge concrete breakwaters built on rocks, that rise above the water.

The station was re-opened in 1928 after the Ministry of Agriculture and Fisheries installed a harbour and breakwaters. This created a resurgence in fishing from Staithes and the RNLI provided a lifeboat. The resurgence was short lived however, the station closed again in 1938.

Both locks would also be connected to the country's power grid and have back-up generator facilities. It was estimated that each lock would have used about 9 megawatts of power. At each oceanic canal entrance, breakwaters and port facilities would have been constructed.

The western breakwater is 1640m long with 140m land-based and 1500m sea-based area. The eastern breakwater is 738m long with 200m land-based and 538m sea-based area. Both breakwaters are made of stacked artificial acrobod piles topped with a concrete head.

This headland is still growing today as more berms are added. Coastal defences against erosion are groynes, stone walls, or tetrapods of concrete, which act as breakwaters. The first plants to colonise the dunes include sea buckthorn or beach grass which prevent wind erosion.

One of the main attractions of the town are the 2 and a half kilometers of sandy beaches in the form of golden beaches, protected by seven longitudinal breakwaters and four in the form of islands. These breakwaters had to be built in the early 1980s due to construction of the reservoir of Foix and the ports of Cubelles (to the north) and Segur de Calafell (to the south) which caused a disruption of the morphodynamic equilibrium, the effect being a visible loss of the beaches. Since 1997 it has been receiving the award of blue flag given by the European Foundation for Environmental Education.

The living breakwaters, however, are not going to exist in an isolated system. SCAPE's design is a part of a layered approach that includes partnerships with the Billion Oyster Project and the Tottenville Shoreline Protection Project, a separately funded project to build similar shoreline protection structures. In addition, part of the Living Breakwaters project's funding is allocated for establishing a “learning hub” to inform local communities about the benefits of oysters and protecting the shoreline ecosystem (Hurricane Sandy Design Competition). This information hopes to encourage residents of Tottenville the surrounding areas to practice sustainable habits, prevent pollution, and continue to engage with the project in the future.

Living Breakwaters serves as an environmentally-friendly, natural oyster reef that should be able to "clean up to millions of liters of harbor water each day." Living Breakwaters has won not only the Rebuild by Design competition, but also the Buckminster Fuller Challenge in 2014, the ACEC NY Engineering Excellence Award in 2015, and the National Achievement Award also in 2015. According to the SCAPE website, the project was due for construction in 2019. Orff was one of presenters at the Landscape Architecture Foundation's The New Landscape Declaration: A Summit on Landscape Architecture and the Future held in Philadelphia on June 10–11, 2016.

The Bombardons were large by cross-shaped floating breakwaters fabricated in steel that were anchored outside the main breakwaters that consisted of Gooseberries (scuttled ships) and Phoenixes (concrete caissons). 24 bombardon units, attached to one another with hemp ropes, would create a breakwater. During the storms at the end of June 1944 some Bombardons broke up and sank while others parted their anchors and drifted down onto the harbours, possibly causing more damage to the harbours than the storm itself. The design of the Bombardons was the responsibility of the Royal Navy while the Royal Engineers were responsible for the design of the rest of the Mulberry harbour equipment.

The beaches of Bocagrande, lying along the northern shore, are made of volcanic sand, which is slightly grayish in color. This makes the water appear muddy, though it is not. There are breakwaters about every . On the bay side of the peninsula of Bocagrande is a seawalk.

Other breakwaters protects the fishing village from large ocean waves. The highest point is just above mean sea level. The Inngripan group of skerries lies about closer to Kristiansund, where a small storm shelter offered protection for shipwrecked fishermen. The storm shelter has recently been restored.

This erosion of the coast of Ancient Sabratha can be seen yearly with significant differences in beach layout and recent crumbled buildings. Breakwaters set in the vicinity of the harbor and olive press are inadequate and too small to efficiently protect the Ancient City of Sabratha.

By 1845 an "exceedingly low" cost steamboat service used to run between Stirling and Granton. Lighthouse engineer Robert Stevenson oversaw the later construction of the outer breakwaters, which were completed in 1863. Thereafter the Resident Engineer was John Howkins, followed by his son, also John Howkins.

The island is approximately in area overall, being in length north-south and in width east- west and is formed by solid granite bedrock. A quarry supplying rough granite for breakwaters (e.g. at Newport, Rhode Island) was located at Pine Hill on the northwestern side of the island.Haynes, William.

Joining the Media Luna causeway was a caponniere. The San Lazaro battery's terreplein included aljibes, while channels and breakwaters dealt with rainwater. The main underground gallery runs along the perimeter of the complex at sea level. Chambers within it could be exploded preventing the advance of overhead attackers.

New technological advancements in port building were made during the building of the quays (built in the dry), the building of the breakwaters, the use of 30 ton dolosse, and the implementation of the sand bypass system (one of only 3 in the world and unique in itself).

Caldera is a port city and commune in the Copiapó Province of the Atacama Region in northern Chile. It has a harbor protected by breakwaters, being the port city for the productive mining district centering on Copiapó to which it is connected by the first railroad constructed in Chile.

The port is protected by 8,230 feet (2,510 m) of steel and rubblemound breakwaters. In addition to the federal help, the state of Indiana showed its support for the Port of Indiana project by constructing two roads, Indiana 149 and Indiana 249, to serve the new industrial area.

Archaeological Park on Cape Posillipo Posillipo is a rocky peninsula about 6 km long surrounded by cliffs with a few small coves with breakwaters at the western end of the Bay of Naples. These small harbours are the nuclei for separate, named communities such as Gaiola Island and Marechiaro.

Understandably, a decision was made to construct two breakwaters to channel the river's flow and these were completed in the early 1900s. The construction of the breakwaters also led to the formation of Shaw's Bay (after sand built up behind what is now called Lighthouse or Main Beach). In 1846, a conflict between white settlers and local Aborigines in the river valley (the Richmond River massacre) caused the deaths of around 100 of the latter. With the decline of shipping as a transport mode, owing to better roads and rail, and the closing of the North Coast Steam Navigation Company (the major shipping firm of the area) in 1954, the river became less important as a port.

One of the most dominant of the defence structures is the Portland Breakwater Fort, located on one of the outer breakwaters. It is Grade II Listed. In 1993, the Dockyard Offices became Grade II Listed. At the end of Castletown village is the former Dockyard Police Station - also Grade II Listed.

The desire was preserve the Moonstone Beach as a tourist attraction. Much of the damage had already been done. With the addition of breakwaters, dredging, and a harbor in the late 1950s, the contour of the Redondo Beach waterfront has changed and moonstones are no longer deposited along its shores.

These works consisted of a main breakwater and a icebreaker pier. Both were built of granite rubble from New Castle County, Delaware, with earlier portions using smaller stones from the Hudson Palisades. The breakwaters are wide at the base and at the top. The project used 835,000 tons of stone.

This type of plant would use shorter (and therefore less costly) intake and discharge pipes, which would avoid the dangers of turbulent surf. The plant itself, however, would require protection from the marine environment, such as breakwaters and erosion- resistant foundations, and the plant output would need to be transmitted to shore.

Ports usually include one or more harbors. Alexandria Port in Egypt is an example of a port with two harbors. Harbors may be natural or artificial. An artificial harbor can have deliberately constructed breakwaters, sea walls, or jettys or they can be constructed by dredging, which requires maintenance by further periodic dredging.

Bincleaves Groyne is a breakwater located off the southern area of Weymouth, England. It is the second largest of four breakwaters which create Portland Harbour. It is separated from the Northeastern Breakwater by the North Ship Channel. A landing stage is situated on the southern side of the breakwater near the Western Ledges.

The Port of Mangalia is located on the Black Sea, close to the southern border with Bulgaria, and over north of Istanbul. It covers of which is land and is water. The north and south breakwaters have a total length of . There are 4 berths (2 operational berths) with a total length of .

Kvalsund is a village in the municipality of Herøy in Møre og Romsdal county, Norway. It is located on the island of Nerlandsøya. Kvalsund is a fishing port with a sizable deep-water harbor, marina, and waterfront protected by breakwaters. Kvalsund is connected to the island of Bergsøya by the Nerlandsøy Bridge.

As a result of heavy development along the eastern shore, there are indications that water quality is degrading; however, restoration efforts are in place. Eelgrass population has also been significantly declining. Dredging and cleanup projects have additionally been established. In the past, breakwaters were established, allowing inflows of sand to "choke" the pond.

In coastal engineering, a tetrapod is a four- legged concrete structure used as armour unit on breakwaters. The tetrapod's shape is designed to dissipate the force of incoming waves by allowing water to flow around rather than against it, and to reduce displacement by allowing a random distribution of tetrapods to mutually interlock.

Port facilities at Outer Harbor were constructed during the first decade of the 20th century. This involved reclamation of marshland and the building of wharves and breakwaters. A railway line was built northwards from Largs in 1903 to facilitate this construction. The line was initially single track and used by goods trains only.

The main part of the population lived outside the fortress in the so-called "slobodas". In 1711 the fortress was defended by 293 cannons and 40 howitzers not counting artillery in the haven and on Cherepakha Islet. Taganrog haven's water area was about 774 thousand sq.metres, of rectangular form and was surrounded breakwaters.

An east-southeast view in Chicago, Illinois overlooking the Jardine Water Purification Plant and Navy Pier within the Chicago Harbor including the north and south breakwaters and the Chicago Harbor Lighthouse Monroe harbor. Generally, the Chicago Harbor comprises the public rivers, canals, and lakes within the territorial limits of the City of Chicago and all connecting slips, basins, piers, breakwaters, and permanent structures therein for a distance of three miles from the shore between the extended north and south lines of the city. The greater Chicago Harbor includes portions of the Chicago River, the Calumet River, the Ogden Canal, the Chicago Sanitary and Ship Canal, Lake Calumet, and Lake Michigan.Municipal Code of Chicago, Chapter 10-40 Chicago Harbor, Article 1.

Edinburghs distinctive forecastle Edinburgh was readily distinguished by her distinctively different forecastle. When it was decided to fit the Phalanx CIWS to this class of warships, it was intended that Edinburgh should carry a single CIWS unit, mounted forward between her 4.5-inch gun and the Sea Dart launcher. To this end, her breakwaters were enlarged and she was fitted with a raised bulwark, very like those carried on the Type 22 frigates. This location proved to be an unsuitably wet one for the Phalanx system despite the modifications to this warship, and Edinburgh was later fitted with a pair of wing-mounted CIWS as carried by the other ships of the class, but she retained her distinctive bulwark and enlarged breakwaters.

Hard engineering techniques were employed in the scheme, including a gabion running to the north of Chiswell, an extended sea wall in Chesil Cove, and a culvert running from inside the beach, underneath the beach road and into Portland Harbour, to divert flood water away from low-lying areas. Portland Harbour was home to the Royal Navy. Their former barracks are in the foreground. At the start of the First World War, HMS Hood was sunk in the passage between the southern breakwaters to protect the harbour from torpedo and submarine attack. Portland Harbour was formed (1848–1905) by the construction of breakwaters, but before that the natural anchorage had hosted ships of the Royal Navy for more than 500 years.

After testing the Decca Navigator System at Moray Firth in early 1944, Scott surveyed positions for the blockships and Phoenix breakwaters of the Mulberry harbour at Arromanches during the Invasion of Normandy. She then surveyed liberated harbours including Morlaix, Boulogne, Brest, Dunkirk and Antwerp; and surveyed locations for the cross-channel pipelines of Operation Pluto.

The nearest town is Pictou some 29 km to the east. There is a small harbour at Skinners Cove, comprising short breakwaters and wharves either side of a narrow channel. It is used mainly by the fishing industry and a few recreational boats. Recent improvements to the harbour were funded by the Government of Canada.

Castle Cornet is a large island castle in Guernsey, and former tidal island, also known as Cornet Rock or Castle Rock. Its importance was as a defence not only of the island, but of the roadstead. In 1859 it became part of one of the breakwaters of the Guernsey's main harbour, St Peter Port's harbour.

Ruddy turnstones can survive in a wide range of habitats and climatic conditions from Arctic to tropical. The typical breeding habitat is open tundra with water nearby. Outside the breeding season, it is found along coasts, particularly on rocky or stony shores. It is often found on man-made structures such as breakwaters and jetties.

Sediment builds up on human-made breakwaters because they reduce the speed of water flow, so the stream cannot carry as much sediment load. Glacial transport of boulders. These boulders will be deposited as the glacier retreats. Sediment is transported based on the strength of the flow that carries it and its own size, volume, density, and shape.

The harbour and dockyard has various buildings and structures that are Grade Listed. The inner breakwater, with its jetty, former victualling store and Inner Pierhead Fort, are Grade II Listed. The victualling store was built around 1850. At the south-west end of Prince Consort Walk is a carved commemorative stone for the completion of the breakwaters in 1872.

Ten teams submitted designs and six of them were eventually awarded funding for their respective projects. One winning design was the Living Breakwaters initiative proposed by landscape architect Kate Orff. Her firm, SCAPE, envisioned what Orff describes as a “living piece of infrastructure” including a barrier that protrudes from the water and houses an oyster reef (Dejean).

In Liverpool, a boat launch and accompanying racing ships and other boats were destroyed. Three breakwaters were heavily damaged on Devils Island, in Brookland, and in Yarmouth, the second costing $80,000 to replace. A fourth breakwater at Western Head was washed away. One marine dredge was destroyed at Cape Negro and another was sunk somewhere between Lunenburg and Shelburne.

Shape of the island was monitored using the global positioning system. The sand on top of the island was sprayed by a technique called rainbowing. Here the sand from the dredging ships was sprayed on to the land. The whole island was planned such that there was no stagnant water between the island and the breakwaters.

Holding the line typically involves shoreline hardening techniques, e.g., using permanent concrete and rock constructions. These techniques--seawalls, groynes, detached breakwaters, and revetments—represent more than 70% of protected shoreline in Europe. Alternatively, soft engineering techniques supporting natural processes and relying on natural elements such as dunes and vegetation can prevent erosive forces from reaching the back-shore.

The Cape Foulwind Railway was a branch railway line west of Westport to Cape Foulwind. In 1886 the Westport Harbour Board built the line to their quarry to transport rocks to their breakwaters in the Buller River. In 1888 it was linked to Westport by a road-rail bridge over the Buller River. About 1890 passenger services were started.

The bridge was built in 1927–28. A prior bridge on the site was torn away by floodwaters on September 30, 1904. Prior to the flood, the city had raised concern about flooding and scouring of the banks. A 1903 ordinance directed adjacent property owners to build breakwaters to protect the river bank, but not everyone complied.

Cavaió Beach is located between the beach of Canet and the municipality of Arenys de Mar, 1000 m long, and is a semi-urban beach. Its composition is sandy, with granite rocks. There is a project for a promenade that links Arenys de Mar, the remodeled the coast with several breakwaters to protect the beach from storms.

The tower is high and the focal plane is high. The light is still operational as a navigation aid. There is a gap between the breakwaters, from which a dredged channel of leads to the dock basin entrance. The channel has a least depth of , with a depth of at spring tides and at neap tides.

Rita caused one of the largest storm surges along the Bohai Sea, with a maximum value of at the Huludao port."The influence of the drag coefficient on the simulation of storm surges"(PDF)Xiuqin Wang, Chengchen Qian, Wei Wang. October 23, 2000. From Tianjin to Dalian port, thousands of boats were destroyed and the breakwaters were damaged.

Expansion of Harbour, 2013 The harbour was badly damaged in the 2004 tsunami. After conducting various studies, the state government decided to carry out an expansion work. The existing eastern breakwaters area were lengthened and a new breakwater area formed on the western side. Once expanded, the harbour could house 150 more mechanized boats, benefiting around 1,500 fishermen.

The community uses breakwaters to hold the roads in place and keep the water from washing them away. The main industry is cod and lobster fishing. Rencontre East was the location of one of only a few molybdenum mines in Canada's history. The mine was located at Ackley City at Rencontre Lake just north of the town.

349x349px Pole Gap is a Safavid multi-arch bridge passing through KhorramAbad city and located near to ShapurKhast castle. Its twenty arches except its breakwaters and piles are made from bricks and mortar. The height of bridge is about 18 meters. Some of its arches are in the underground of the shops in two sides of the bridge.

199x199px Spar platforms, artificial and natural breakwaters and active repositioning, if applicable, of ocean structures to avoid storms are some suggestions and technologies suggested by ocean colonization supporters and scientists to combat extreme aquatic weather events . Entrepreneurs such as Friedman, have acknowledged and are aware of the care that must be taken in the engineering process of these designs .

Also known as the white-plumed anemone are broad oral disc covered with short, slender, tapering tentacles and when they extend they become tall and slender. Plumose anemone are colored from a white, cream, tan, orange, or brown shade. Usually can be found on pilings, floats, or breakwaters in bays and harbors in Southern Alaska to Southern California.

The top of the breakwater is about wide, while its underwater base is an estimated wide. The visible top is formed out of coursed granite blocks. About 700,000 tons of rock were used in its construction. The breakwater is believed to be unique among Army Corps 19th-century breakwaters in its exclusive use of local materials.

Modern baulk road at London Paddington station Baulk road was used by John Coode for a number of railways that he built as part of large construction schemes for harbour breakwaters at places such as Portland and Table Bay. The great widths between the rails and between the transoms allowed him to support the tracks on piles and discharge rocks from wagons directly between the rails to form the foundations of the breakwaters. A variant of baulk road can still be seen today on some older under-line bridges where no ballast is provided. The design varies considerably, but in many cases longitudinal timbers are supported directly on the cross-girders, with transoms and tiebars to retain the gauge, and modern rails and base-plates or chairs laid on top.

The developers Conygar have been granted outline planning consent by Pembrokeshire County Council for a 450-berth marina, 253 apartments, 76 one-bed and 177 two-bedrooms, 200 sq m of shops and 500 sq m of financial and professional services; 840 sq m of restaurants and cafe space; a light industrial area, along with a boatyard, workshop and fishing stores, visitor parking and a 19 acre platform for the potential expansion of the existing Stena Line port. The scheme will also create a publicly accessible promenade and waterfront. Two breakwaters to protect the marina are also proposed. Most of the proposed new developments will be sited by reclaiming land from the sea bed within the two existing breakwaters mainly near the current 'Ocean Lab' and alongside the existing ferry terminal access roads.

Other disarmed French ships have been used as breakwaters before the château de Brest or as training ships off the naval school at Lanvéoc-Poulmic, but those at Landévennec await demolition or use for target practice in naval exercises at sea. Despite requests from Landévennec's mayor, the aircraft carrier Clemenceau was not retired to the base, with the Capelan bank apparently discouraging pilots from attempting to navigate it into the base. However, having been emptied of nearly all its occupants, in August 2006 the graveyard took on three former breakwaters which would become Brest's "port du Château" and had been moved to allow expansion work to begin. The cruiser Colbert and the Soviet-built hydrofoil ferry Kometa from the Penn-ar-Bed company (which provided summer services to Ushant) are now also based here.

It also altered the hydrogeographic balance between the input of fluvial and sea water in the lagoon. In the late 19th and early 20th century breakwaters were built at the inlets to stop the accumulation of sand there and ensure their navigability. The fluvial system of the gronda lagunare was complex and unstable. Several rivers flow into the lagoon along its length.

They thus have great potential for many applications, such as making breakwaters. If waves or colliding ships cause damage, renewed accretion makes them, to an extent, self-repairing. Biorock is cost-effective, requiring only metal bars or equivalent and electricity. While electricity provided from fossil fuels generates CO2, biorock projects often use renewable solar power, wind power, tidal power, or wave power.

Two Rivers Lighthouse located at Rogers Street Fishing Village and Museum.This light was preceded by a brick structure on shore, one and a half stories with a cupola. This light was erected in 1852 and lasted only until 1858. A project to improve the harbor was begun in 1870, including the construction in stages of a pair of breakwaters defining the entrance channel.

The coastline is unstable. The southwest monsoon carries sediment along the coast, at times forming bars and spits that protect the harbours, at other times eroding the protective breakwaters. The rivers carry silt, extending their deltas and filling the former harbours. For this reason, some of the ports named in ancient times are no longer in existence, or have greatly declined.

This island is a bird sanctuary. Its surroundings are highly phosphatized that superphosphate materials can be mined out on a small-scale basis. Near the fringes of the breakwaters (approx. 2 miles (3 km) from the island), intact hard coral reefs were observed to retain their natural environment and beautiful tropical fishes were seen colonizing these coral beds of varying colors.

Having little stone available nearby, shaped concrete blocks were cast on-site. These allowed a more sophisticated shaping than was economic with stone, and large interlocking blocks could be used. However this also required a crane with greater lifting capacity. Two large breakwaters were constructed at the sea mouth at IJmuiden and the Zuiderhoofd and sea wall dyke at Westkapelle.

The total width of the breaches had grown to three kilometers. The depth of the tidal trenches was tens of meters in places. For this reason new techniques of hydraulic engineering had to be developed. To block the deepest parts of the breaches surplus caissons, originally built for the Phoenix breakwaters of the Mulberry harbours, were given a new application.

Taum Sauk (Missouri) pumped storage facility in late November 2009. After the original reservoir failed, the new reservoir was made of roller-compacted concrete. Due to cement's exothermic chemical reaction while setting up, large concrete structures such as dams, navigation locks, large mat foundations, and large breakwaters generate excessive heat during hydration and associated expansion. To mitigate these effects, post- coolingMass Concrete .

Coastal engineering of harbours began with the origin of maritime traffic, perhaps before 3500 B.C. Docks, breakwaters and other harbour works were built by hand, often in a grand scale. Ancient harbour works are still visible. Most of the grander ancient harbor works disappeared following the fall of the Western Roman Empire. Most coastal efforts were directed to port structures.

Freshwater Bay, and the pumping station. Freshwater Bay takes its name from a freshwater spring which emerged at the bottom of the cliff. An Admiralty pumping station was built on the clifftop in the 19th century for supplying fresh water to the naval base and to the harbour's breakwaters during their construction. Cheyne House was built for the attendant of the station.

The hills surrounding the village feature Eucalyptus trees and coastal chaparral vegetation. The isolation of the area and undeveloped lands make deer sightings commonplace. Other animals in the area include the endangered salt marsh harvest mouse and California clapper rail. The areas around the marina and breakwaters have many egrets, herons and other birds that enjoy the small wetlands areas.

The current and potential damage to reefs could affect Guam's tourist industry. A 2007 study estimated that reefs' economic value may be $2 million per square mile, both on account of tourism and their role as natural breakwaters. Bleaching of reefs may lead to declines in tourist revenue, a direct economic impact. Climate change could also affect the military bases on Guam.

Port Construction: The Port's main construction and engineering outfit is CCCC First Harbor Engineering (中交第一航务工程局有限公司). Four subsidiary companies carry out all forms of project engineering and construction, from roads to breakwaters. As of 2010, First Harbor Engineering First Company (the main boat outfit) had a fleet of 74 work vessels.

Karaikal Port is a deep draft, all weather port. The current depth of 14.5 m allows for handling of Gearless Panamax size vessels (up to 800000 MT). The final depth of 41.5 m will allow cape size vessels (up to 120000 MT) to call at the port. The lagoon type basin protected by breakwaters allows operations all around the year.

The main construction work included two berths for handling coal vessels up to 65,000 DWT, dredging for the approach channel and harbour basin, onshore civil works, navigational aids, and two breakwaters—4 km in the north side and 1 km in the south—close to the NCTPS and the Ennore Creek. In 2014, the port was officially renamed as Kamarajar Port.

The Damietta Port Authority Egypt's Damietta Port is located 10 km west of the Nile river of Damietta branch westward Ras El-Bar, 70 km to the west of Port Said and 200 km from Alexandria Port. The port installations extend on an area of 11.8 km2. The port is bordered by an imaginary line connecting the eastern and western external breakwaters.

Durban's South Pier with a line of interlocking dolosse, South Africa They are used to protect harbour walls, breakwaters and shore earthworks. In Dania Beach, Florida, dolosse are used as an artificial reef known as the Dania Beach Erojacks. They are also used to trap sea-sand to prevent erosion. An order of 10,000 dolosse are required for a kilometre of coastline.

The center of the storm tracked within northeast of Kwajalein Atoll on the morning January 4 before passing within south of Enewetak two days later. Rough surf at Kwajalein damaged breakwaters and piers. Sustained winds there reached with gusts to . Significant shoreline damage occurred along the lagoon-facing shores of the Kwajalein Missile Range, compounded by Alice's nearly stationary movement.

The threadfin jack is also of interest to anglers who catch the species occasionally, and is considered a minor gamefish. Juveniles are occasionally caught from shore, such as piers and breakwaters, while larger individuals are caught over deeper reefs. The species takes a variety of bait, including fish and prawns, but they also take lures, including hard and small, fly-like Sabiki lures.

The "double oak" refers to a tree with two different trunks that grows separately but is nonetheless united. "Under the roof of one crown" expresses the wish to have a common government. The "threatening north" and the "mild south" allude to Denmark and Germany respectively. The "wild breakwaters" are bothersome foreign influences, and "inner tempests" apply to conflicts within Schleswig.

The Harbour of Refuge (Admiralty Backwaters) was begun in 1886 by Sir John Coode. It was built by convict labour. The present harbour, now a Category B listed structure,PETERHEAD HARBOUR LB39733 - Historic Environment Scotland has two massive breakwaters, enclosing an area of approximately in Peterhead Bay. The south breakwater, about long, was constructed in 1892–1912 using convict labour from the prison.

Large Xblocs () on a trial placement area An Xbloc is an interlocking concrete block (or "armour unit") designed to protect shores, harbour walls, seawalls, breakwaters and other coastal structures from the direct impact of incoming waves. The Xbloc model has been designed and developed by Delta Marine Consultants since 2001 and has been subjected to extensive research by several universities.

It is segmented by a series of timber breakwaters which are designed to retain sandy deposits along the beach. Groyne on Rosslare beach There are a number of golf courses in the vicinity. Rosslare also has several hotels, cafes and restaurants. As of the 1996 census, the village had a population of 929 people, increasing to 1,620 by the time of the 2016 census.

The Port of Midia is located on the Black Sea coastline, approx 13.5 NM north of Constanţa. It is one of the satellite ports of Constanța and was designed and built to serve the adjacent industrial and petrochemical facilities. The north and south breakwaters have a total length of 6,97 km. The port covers 834 ha of which 234 ha is land and 600 ha is water.

Several buildings in the Upper Peninsula and across the United States incorporate Jacobsville Sandstone in their construction. In the Upper Peninsula, these buildings include The Calumet Theatre, Saint Ignatius Loyola Church, and several buildings in the Quincy Street Historic District. Elsewhere, the sandstone was used in the original Waldorf-Astoria Hotel in New York City. The rubble stone was commonly used for foundations, cribs, breakwaters and piers.

The Grip archipelago consists of 82 islets and skerries about into the Norwegian Sea northwest off the town of Kristiansund. The fishing village of Grip (no permanent residents) is located on Gripholmen, which is the largest and only habitable islet. On the south side of the fishing village is the main harbor, protected by two breakwaters. The older and northern harbour is smaller and less protected.

An upstream weir and additional arch were likely built to accommodate a mill race feeding Clonmoyle Mill to the south. The weir and mill race are both depicted on the 1901 surveyed OS Map. Many surviving bridges in mid-Cork are originally constructed of stone, arched in shape, and late eighteenth or early nineteenth century in date. Typical features include semi-circular arches and pointed breakwaters.

Both offer boat rides and bicycle paths. At the South Beach, where breakwaters protect the mouth of the Tecolutla River, there are also beachside cabins. Docks serve boat rides up the river, as well as fishing expeditions on the river and in the Gulf. A type of boat often used to navigate around the estuaries is called a panguita, which looks like a very long canoe.

The north and south breakwaters have a total length of . The port covers of which is land and is water. There are 14 berths (11 operational berths, three berths belong to Constanța Shipyard) with a total length of . Further to dredging operations performed the port depths are increased to at crude oil discharging berths 1–4, allowing access to tankers having a maximum draught and .

Major railway lines halted operations throughout central Japan while many other trains arrived late, leaving 18,000 individuals stranded. Throughout the nation, 24 homes were damaged or destroyed while 3,400 others were flooded, displacing 2,700 persons in eight provinces. In all, 19 bridges and two breakwaters were washed away, which resulted in 83 landslides. Eighty-nine roads were damaged, of which 50 were closed, trapping thousands of travelers.

Several ferry companies have provided transportation to Star Island. The Isles of Shoals Steamship Company, Island Cruises, and We Like Whales bring visitors for day trips and overnights or run tours around the island and the rest of the Isles of Shoals. Gosport Harbor, which is created by the islands and connecting breakwaters, is deep and fairly protected, and moorings are available for visiting boats.

Opened in 1863, the quarry employed as many as 100 men in the 19th century. It was closed for two decades from the 1960s to the 1980s, but now employs ten people. Wallace sandstone has a marked olive hue and can be found in many buildings around the Maritimes and eastern Canada. Originally used for foundations, breakwaters and bridge abutments, it is now a facing stone.

The beach is protected by breakwaters. The park has barbecue pits, chalets, food centres and amenities for various sports activities. Visitors can fish at Bedok Jetty (Area F). A cycling and inline skating track runs along the perimeter of the park, which measures over long. It is connected to Changi Beach Park by the Coastal Park Connector Network, a park connector running along Tanah Merah Coast Road.

Throughout North Carolina, the hurricane caused about $40 million in damage, of which about 75% was from crop damage. There were 27 deaths in the state related to Connie, including traffic deaths, drownings, people in damaged buildings, and electrocutions. In South Carolina to the south of the center, the hurricane destroyed 40 buildings in Myrtle Beach, South Carolina. Connie also damaged fishing piers, breakwaters, and housing shingles.

These structures combined used approximately 344,500 m3 of concrete (or 826,800 tons). A crane driver using a global positioning system (GPS) fitted to the end of his crane ensured that each of the two- storey tall structures was precisely placed to meet to the calculated coordinates of the model studies. The dolosse protect the breakwaters by dissipating rather than blocking the energy of incoming waves.

The Holland Harbor Light, known as Big Red, is located in Ottawa County, Michigan at the entrance of a channel connecting Lake Michigan with Lake Macatawa, and which gives access to the city of Holland, Michigan. The lighthouse is on the south side of the channel. There are two modern lights marking the ends of the breakwaters that extend out into the Lake Michigan beyond the lighthouse.

The mouth of the Chuí Stream is not only the southernmost, but also the westernmost point of the Brazilian coast, as well as both the northernmost and easternmost point of the Uruguayan coast. It also marks the southern end of Cassino Beach, the world's longest uninterrupted stretch of sandy ocean shore, stretching over from the stone breakwaters of Rio Grande in its northern end.

Outer harbor Inner harbor In 1896 Congress authorized a new, larger program of breakwaters, the National Harbor of Refuge. Located to the north of the original breakwater on a shoal known as The Shears, the new breakwater used much larger stone. The dressed and fitted masonry used individual pieces of up to 13 tons. The new breakwater was long at low water and wide.

The port of Ravenna is the main port of Emilia-Romagna. The European Commission has appointed the Ravenna seaport "Core port" of the TEN-T Networks. The docks are mainly on a canal that connects the town centre of Ravenna (which is inland) to the sea which is 12 km away. The offshore breakwaters are in the little towns of Porto Corsini and Marina di Ravenna.

Isis Temple Kenchreai flourished during the Roman Empire, when the settlement was focused around the crescent-shaped harbour enclosed by massive concrete breakwaters and protected by sea-walls. The local community was small but prosperous, and it was distinguished by its social, cultural, and religious diversity. Ancient literature and inscriptions from the site attest to the presence of cults of Aphrodite, Isis, Asklepios, Poseidon, Dionysos, and Pan.

The solution the COSSAC planners adopted was innovative and audacious: to build a prefabricated harbor. While ports like Dover and Cherbourg were artificial in the sense that their sheltered harbors had been created through the construction of breakwaters, there was a significant difference between building Dover in seven years in peacetime, and prefabricating an artificial port in a matter of months, and erecting it in two weeks in wartime. Originally, there was to be one artificial port, at Arromanches in the British sector, but by October 1943 COSSAC added a second one at Saint-Laurent in the American sector. At this time the project acquired a codename: Mulberry, with the American port becoming Mulberry A and the British one Mulberry B. British Rear Admiral Sir William Tennant was in charge of the operation, with the American Captain A. Dayton Clark in charge of Mulberry A. The Mulberry harbor had three breakwaters.

Biorock structures are extremely effective at preventing beach erosion and restoring already eroded beaches. Shorelines are highly susceptible to beach recession and loss due to climate change bringing about rising sea levels and increasingly frequent and powerful storms. Conventional methods of combatting this employ large structures such as breakwaters that are designed to reflect waves, thus preventing erosion. However, this method is problematic and actually contributes to beach erosion.

The 19th-century construction of Portland Harbour's Breakwaters, and the other associated works, led to a large increase within Portland's population. Brackenbury's chapel had become too small and fallen into a poor condition by this time. It was decided that a new church should be built, and was to be called Brackenbury Memorial Church. The foundation stones were laid in 1898, and the church was completed by 1899.

Therefore, the highest numbers of Northeastern beach tiger beetles are found on natural beaches (beaches without infrastructure). However, if properly built, offshore breakwaters decrease wave energy on beaches and can preserve beetle habitat. Humans also negatively impact Northeastern beach tiger beetles by compacting sand—either by foot or vehicular traffic. Larvae wait at the top of their burrows for prey, but stomping and compacting the sand covers the burrows.

The stonework, which was used in constructing the lighthouse, is laid in such a way to give a impression of a black and white spiral on the tower. The lighthouse was operational until the 1977 but is no longer functional. In 2012 lighthouses were constructed on the eastern and western breakwaters of the Hambantota port. The tower was restored in 1999, with the stonework being painted over in black and white.

The Port of Mangalia is situated on the Black Sea, located in the city of Mangalia close to the southern border with Bulgaria, and over 260 km north of Istanbul. It covers 142.19 ha of which 27.47 ha is land and 114.72 ha is water. The north and south breakwaters have a total length of 2.74 km. There are 4 berths (2 operational berths) with a total length of 540 m.

The merchants, becoming landlords, also bought most of the private properties. Storm surges destroyed most of the fishing village in 1796 and again in 1804, leaving only the church and a few other houses. The first breakwaters were constructed in 1882 and a harbor capable of landing small ships was not ready until 1950. The new harbour provided excessive materials which were used to create a small football pitch.

World War II ruins on Lepe beach Lepe was used as a secret manufacturing site. Six massive concrete caissons (type B2 Phoenix breakwaters) were built here then towed across the Channel where they formed part of the Mulberry harbours used after D-Day. Lepe was also one of the many places of embarkation of troops and equipment. Concrete mats shaped like big chocolate blocks reinforced the shingle beach for heavy vehicles.

Block-setting cranes were large cranes developed in the mid-Victorian era. They were used for installing the large stone blocks used to build breakwaters and stone piers. They could lift a heavy stone block and place it precisely, with a long jib reaching beyond the base of the crane. Several types of such crane were developed, with progressively greater reach, lifting capacity and ability to move their load sideways.

The dark colour of the water between the two breakwaters in the foreground indicates the position of the scuttled battleship . The western side of the Harbour with Chesil Beach, Lyme Bay and the Fleet Lagoon in the background. Portland Harbour is located beside the Isle of Portland, Dorset, on the south coast of England.

Nicodemus Knob and the surrounding area. Nicodemus Knob was left as a pillar within the former Admiralty Quarries, which provided stone for the breakwaters of Portland Harbour between 1849-72. It marks the extent to which the convicts excavated stone from the quarries; some six million tonnes of stone was taken from the area, using convict labour from the nearby Portland Convict Establishment. The stack's intended purpose is uncertain.

In the first hour, Ellyson identified coastal battery fire nearby the town of Gruchy. Glasgow and her air spot silenced it with 54 rounds. The destroyer Emmons answered the fire on Fort De l'Est on one of the harbor breakwaters, but by the time the target was silenced, a well camouflaged battery began walking fire closer to the ship operating from a range of . Rodman dropped smoke, and Emmons withdrew.

Diver inspecting blocks Fork-lifting is effective for handling the small to medium size units, whereas large units are handled by sling. Placement for breakwaters generally requires a crane or a barge-mounted crane. The units can be stored one on top of the other, and placed in a random attitude to obtain the specified packing density. The proper packing method provides an adequate coverage on breakwater slopes.

Opened in 2011, this OWC power plant can generate approximately 300 kW at proper conditions (enough to power 250 houses) with its 16 Wells turbines. The turbines were provided by Voith, a company which specializes in hydropower technology and manufacturing. The collecting chambers and turbines are housed in a breakwater. Breakwaters are man made walls (built offshore) which block the coastline from wave activity (often used around harbors).

It is about a mile from the beach. It is not quite covered at high tide, but it is topped by a beacon to warn shipping of its presence. Four Phoenix breakwaters were used in the Netherlands to plug a gap in the dyke at Ouwerkerk after the North Sea Flood of 1 February 1953. They have now been converted into a museum for the floods called the Watersnoodmuseum.

Coral reefs protect shorelines by absorbing wave energy, and many small islands would not exist without reefs. Coral reefs can reduce wave energy by 97%, helping to prevent loss of life and property damage. Coastlines protected by coral reefs are also more stable in terms of erosion than those without. Reefs can attenuate waves as well as or better than artificial structures designed for coastal defence such as breakwaters.

Human beings have played a role in the ecology of Presque Isle since at least the Erielhonan. The natural drift of sand is hindered or stopped by breakwaters, permanent structures, and roads. Roads also do not absorb rainwater, causing erosion, and break up natural habitats. Excavations such as those to make the waterworks basins or the marina have destroyed habitats, but yearly artificial replenishment with sand helps to create new ones.

They pass through in November on their long flights south and return in April on their flights north. Erosion and deposition of sand, which has formed Gull Point, continues to change it. From May 1991 to October 2006, Gull Point lost a total of , and if this trend continues, it may become an island. After the breakwaters were constructed in 1992, less sand was added to replenish the beaches.

Automation was incorporated into the design of CNB to reduce manpower requirements. It has an automated underground ammunition depot that allows ammunition to be loaded onto the ships and an automated warehouse system to store items. The base has a fibre-optic broadband network for information management. The base was also designed to be environment-friendly, with three small-scale wind turbines powering the 50 lights along the breakwaters at night.

Rising ocean temperatures are also a major environmental challenge facing the Maldives. Rising sea surface temperatures cause significant damage to coral reefs, which serve as natural breakwaters. The death of the coral reefs surrounding the Maldives could lead to the loss of the natural protection those reefs provide from waves and currents, in turn increasing the likelihood of beach erosion. The rise in sea surface temperatures also leads to coral bleaching.

The steam plant and moving parts could be removed and re-used, whilst the large but relatively framework was scrapped in situ and a new one built for the new site. A single crane might construct several breakwaters in its working life. In later years, such cranes were in less demand and so the crane might be left in place, and available in the future for any maintenance work needed.

As an example, Tynemouth Pier had three cranes permanently in place at various times. The two breakwaters were constructed under the supervision of P. J. Messent (1830-1897) "the maker of the Tyne River". The first crane was used to rebuild the North pier and breakwater in 1909 and remained in service afterwards until 1931. The next crane was a steam-powered Titan hammerhead, which lasted to the late 1960s.

As design wave heights get larger, rubble mound breakwaters require larger armour units to resist the wave forces. These armour units can be formed of concrete or natural rock. The largest standard grading for rock armour units given in CIRIA 683 "The Rock Manual" is 10–15 tonnes. Larger gradings may be available, but the ultimate size is limited in practice by the natural fracture properties of locally available rock.

The structural proposals consist of numerous strategies. One possible structure is a breakwater. Breakwaters are placed a few hundred feet offshore and create a harbor. Unfortunately, a breakwater would likely adversely affect littoral drift and the creation of a Goleta Bay harbor is probably too extreme. Another strategy is the installation of groynes (or groins), wood or concrete ‘fences’ that stretch out into the ocean, perpendicular to the beach.

However, such ideas were according to Max Perutz, impractical. In September 1943, Pyke proposed a slightly less ambitious plan for pykrete vessels to be used in support of an amphibious assault. He proposed a pykrete monitor long and wide mounting a single naval gun turret; this could be self-powered or towed to where it would be used. He also suggested the use of pykrete to make breakwaters and landing stages.

Born on Galway's Long Walk on 13 August 1864, he was the youngest child of Gregory Yorke, a sea captain, and his wife, Bridget, née Kelly. Gregory Yorke died six months before Peter was born. The Yorke family were originally from Holland, where the name was spelled Jorke. Peter Yorke's grandfather, Christopher Yorke, came to Galway in the early 19th century, building lighthouses and breakwaters in Galway, Aran and Westport.

Eventually a harbour was built in Table Bay by a process of land reclamation and was defended by breakwaters to protect shipping. The older part of this structure is called the Victoria Dock; the newer part, the Duncan Dock. Robben Island, where Nelson Mandela was imprisoned for decades, is in this bay. The bay's beaches were oiled following an accident involving the Dutch tanker Sliedrecht in November 1953.

The Port of Liepāja has a wide water area and consists of three main parts. The Winter harbour is located in the Trade channel and serves small local fishing vessels as well as medium cargo ships. Immediately north of the Trade channel is the main area of the port, separated from the open sea by a line of breakwaters. This part of the port can accommodate large ships and ferries.

During severe storms the beach is inundated and the breakers strike the dune line. A number of ships have been wrecked in the shallow waters off Plum Island Beach. The Labrador Current flows from north to south along the shore, migrating sand in that direction and chilling the coastal waters. Several breakwaters have been constructed along the north coast of the island to protect the beach and impede the process.

Aerial panorama of Wet 'n' Wild and its surrounds Waterfront canal living is a feature of the Gold Coast. Most canal frontage homes have pontoons. The Gold Coast Seaway, between The Spit and South Stradbroke Island, allows vessels direct access to the Pacific Ocean from The Broadwater and many of the city's canal estates. Breakwaters on either side of the Seaway prevent longshore drift and the bar from silting up.

Eleven sections of the breakwater sustained major damage, including three areas which were completely gouged out. Along the breakwater, of it sustained major damage, saw significant damage, and a further experienced moderate damage. Several hundred tons of rock were estimated to have been dislodged by the storm. The nearby San Pedro and Long Beach breakwaters saw substantial damage as well, though not as severe as the middle breakwater.

These act as breakwaters, allowing mangroves to grow which is one of the ways the breakwater can be spotted from a distance. Some parts of the causeway are made from the bedrock, but usually the bedrock was used as a base. Coral stone was used to build up the causeways with sand and lime being used to cement the cobbles together. Some of the stones were left loose.

KOLOS are randomly placed on rubble mound breakwaters in two layers. Like most of the concrete armour units, the hydraulic stability of KOLOS is dictated by its self weight and interlocking with surrounding units. KOLOS is found to have almost the same level of porosity as Dolos with a layer coefficient of 1. The random placement of the units facilitates increased rate of placement and less dependence on complex placement techniques.

The piers themselves were protected on their up- and downstream side by large cutwaters with pointed caps. Slot-like hollow chambers (view from west) The bridge is 5.60 m wide and around 158 m long. Hasluck gave the spans of the third and seventh opening as 12.20 m each. The facing, including breakwaters and hollow chambers, consists of granite blocks, whereas the interior is filled with mortar-bound rubble.

The first extensions of the medieval wooden bridge were carried out in 1375 and 1420/21. The medieval bridge was wider than necessary, and housed the mills of the Oetenbach Nunnery, as shown by the altarpiece of the Grossmünster Zwölfbotenkapelle by Hans Leu. Only the breakwaters at the inflow side were built of stone, which can be seen on the Murerplan. All other sections of the bridge consisted mostly of wood.

China has not offered Pakistan any line of credit for CPEC infrastructure development in the same manner as India has for Iran.No reference to credit lines is to be found in list of MoUs As part of CPEC, China has instead has committed $1.153 billion to finance construction projects and development of the port and adjacent sites.See below: List of projects $230million for Gwadar Airport, $114m desalination plant, $35m for SEZ infrastructure, $360m for coal plant, $140m for East Bay Expressway, $100m for hospital, $130m for breakwaters, $27m for dredging. Sum of figures = $987million Chinese commitments in Gwadar as part of the CPEC project include: the construction of the $140 million East Bay Expressway project to connect the port with the Makran Coastal Highway, installation of breakwaters at Gwadar port which will cost $130 million, a $360 million coal power plant adjacent to Gwadar Port, a $27 million project to dredge berths in Gwadar harbour, and a $100 million 300-bed hospital in Gwadar.

Over the centuries the village was largely made up of open space, with high-quality houses spread out across the community. From the 1840s onwards Portland saw a large increase within its population, due to the construction of Portland Harbour's Breakwaters. The housing demands placed upon the island saw the originality of Fortuneswell altered. A large number of terraces were erected across the village area, and were crammed into any available open space.

Port Washington harbor is surrounded by breakwaters to protect ships from strong waves. Downtown Port Washington as seen from one of the bluffs overlooking the city. According to the United States Census Bureau, the city has a total area of , of which is land and is water. The city is bordered by the Town of Port Washington to the north and west, the Town of Grafton to the south, and Lake Michigan to the east.

Pedreira is a small lake that exists since late 20th century as an unavoidable casualty, despite being the work of man. The site was a quarry used to extract granite to the build the breakwaters of the port of Póvoa de Varzim in the 1930s. "Lagoa", in Portuguese, is used to refer to small freshwater lakes and saltwater lagoons. With the exaction of the stone, an aquifer was reached and groundwater kept entering the quarry.

HM Prison Portland was established in 1848 to provide convict labour within the Admiralty Quarries, which produced the stone for the breakwaters of Portland Harbour. As part of the subsidiary operations within the quarries, Grove Lime kiln was used for lime production and dates from around 1900. It was constructed and operated by prisoners. In 1921, the prison was converted into a Borstal Institution and as a result, the quarry and associated masonry works closed.

The light armament consisted of two quadruple 2 pounder mounts Mark VII and their directors with Radar Type 282, a pair of twin Oerlikon mounts Mark V in the bridge wings and six single Mark III Oerlikon pedestal mounts. Dragon and Durban were expended as breakwaters in support of the Normandy landings in June 1944, Dragon being replaced in Polish service by the Danae (as ORP Conrad) and Despatch was disarmed as a depot ship.

Construction of the harbour began in 1849; when completed in 1872, its surface area made it the largest man-made harbour in the world, and remains one of the largest in the world today. It is naturally protected by Portland to the south, Chesil Beach to the west and mainland Dorset to the north. It consists of four breakwaters — two southern and two northern. These have a total length of and enclose approximately of water.

The flooded inside area was then filled by divers bit by bit with pozzolana-lime mortar and kurkar rubble until it rose above sea level. On the southern breakwater, barge construction was used. The southern side of Sebastos was much more exposed than the northern side, requiring sturdier breakwaters. Instead of using the double planked method filled with rubble, the architects sank barges filled with layers of pozzolana concrete and lime sand mortar.

It handles most of the country's imported cargoes. Two breakwaters, 2,359m and 2,200m long, protect the harbour, enclosing a basin of 300 hectares of protected water. The general cargo berth, (the main pier), consists of an opened piled, 610m long by 11m wide marginal wharf with a reinforced concrete deck. The main wharf serves 2nd and 3rd generation coastal and mainline vessel. The Port of Buchanan is located 170miles South-east of Monrovia.

The Friendship Port (Port de l'Amité) is an artificial deepwater port located in Nouakchott, Mauritania. It was built during the 1980s by a Chinese company to allow the city, capital of Mauritania, to be supplied more cheaply than by overland from Dakar, Senegal. As the location is not a natural harbor, concrete block breakwaters had to be used to create a safe location for the ships. Plans are being made to increase its capacity.

The nature of the Phoenix breakwaters meant they were constructed and sunk until needed (so as to be invisible to air attack); by design they would have had the water evacuated by Royal Engineers and then been towed to France where they would have become part of the harbour. There is a P.L.U.T.O. or Pipe Line Under The Ocean, station, formerly used to carry petrol across to France during the D-Day landings.

Over the course of several years, a series of financial setbacks causes Mme. Chanteau to "borrow" from Pauline's inheritance. Lazare's investment in a factory to extract minerals from seaweed and his project to build a series of jetties and breakwaters to protect Bonneville from the pounding waves — and the subsequent failure of both these enterprises — reduce Pauline's fortune even further. Through it all, Pauline retains her optimistic outlook and love for Lazare and his parents.

The harbour lies along the Gulf of Guinea and is 18 miles from Accra, the capital of Ghana. The harbour has a water- enclosed area of 1.7 million square metres and covers a total land area of 3.9 million square metres. The harbour lies on a 410 acres (166 hectares) of sea. The harbour has 5 kilometres of breakwaters, 12 deepwater berths, one oil- tanker berth, one dockyard, warehouses, and transit sheds.

Most of the wave action energy is deflected to the side by their angular design. Over time the structures settle and lock into place as the waves subtly shift them. Together, they form an interlocking yet porous wall that grows stronger with time. A double layer of 30 ton dolosse units was placed along the exposed side of the breakwaters and a single layer was placed along the leeward side of the main breakwater.

More development followed, and in 1886 the county seat was moved to Leland. In the early 1900s, fishermen began enclosing their open boats and adding gasoline engines, which increased the scale of fishing operations. By 1937, two breakwaters were constructed in the waters of Lake Michigan, which also facilitated the rise of the local fishing industry. However, in the 1940s, the whitefish and trout populations in the lake were decimated by sea lampreys.

However, salt water intrusion is killing lots of these plants, so keeping the plants from dying can help impede the process of coastal and wetland erosion. Another way to combat coastal erosion is to create seawalls and breakwaters. Seawalls are manmade barriers that are erected to keep seawater from reaching the coast. Because the seawater is unable to reach the coast, the water is unable to erode the coastline, thus preventing coastal erosion.

Davies (2008), p.3 The River Afan commences the wide sweep of Swansea Bay, which from Port Talbot arcs around taking in Baglan Bay, Briton Ferry, Swansea and ending in Mumbles. The whole bay is shut in by high hills and is thickly encircled with sands. Within the bay are two of the major estuaries of Glamorgan; from Port Talbot the first is the River Neath, which is protected by long breakwaters.

The Seabees built the infrastructure needed to take the war to Japan. By war's end CBs had, served on six continents, constructed over 300 bases on as many islands.Seabees, U.S. Navy Official website, 12 August 2009 They built everything: airfields, airstrips, piers, wharves, breakwaters, PT & seaplane bases, bridges, roads, com-centers, fuel farms, hospitals, barracks and anything else. Atlantic In the Atlantic Seabees biggest job was the preparations for the Normandy landing.

The Royal Walls are a land front running across the isthmus separating Ceuta from the rest of North Africa. The walls consist of two large bastions at each end of the wall, which are called Baluarte de la Coraza and Baluarte de la Bandera, and a smaller bastion at the north flank. They are protected by a ditch filled with seawater. Batteries were also built on breakwaters at either side of the walls.

The oysters will bring in their prey as well as naturally filter the water making it more attractive to marine life. This growing ecosystem is a large opportunity for local classrooms to get involved and see marine biology in action. The people have a voice in the project too. The Living Breakwaters citizens advisory committee was established in 2015 and looks to gather opinions of the locals on decisions through the project.

In 2003, a massive beach restoration project was completed by the city, the U.S. Army Corps of Engineers, and the Virginia Port Authority, which involved a large-scale rebuilding of sand dunes, planting of vegetation, and the placement of 10 offshore breakwaters to slow erosion and protect the neighborhood from coastal storms. In 2007, the American Shore and Beach Preservation Association named East Beach one of the nation's top seven restored beaches.

At the time, the beach was a narrow sand bar connecting Hunter Island and Rodman's Neck. There was a retaining wall behind the sand bar, and breakwaters allowed water from the Long Island Sound to pass through the sand bar. The retaining wall frequently flooded at high tide, which made the sand bar effectively unusable most of the time. There were approximately 600 families using the bungalows near the sand bar, as well as bathhouses made of granite pavers.

Each terminal had a lifting dock containing a steel grid measuring by connected to 20 hydraulic jacks. The grids supported the cradle which carried the vessel. The cradle was pulled from the lifting dock by hydraulic power and was then pulled along the length of the ship railway by 2 steam-powered locomotives. The terminal at Tidnish Cross Roads was located on Baie Verte and had a moderate tidal range and was protected by two breakwaters.

This is long, wide, and can accommodate ships with a draught of . In 1944, the port was used as a departure point for troops going to France for the D-day landings. Trade increased further when a second coal- fired power station was commissioned in 1953. The entrance from the sea was improved in 1957, by the addition of east and west breakwaters, and in 1958 Prince Philip, Duke of Edinburgh opened an additional lock, which carries his name.

Fulton suffered from poor health in the climate of the USA and, in 1829, he returned to Britain. There he employed one of his eight children, Hamilton Henry Fulton, as a pupil. In 1832, Fulton made proposals for the construction of a harbor and breakwaters at the coalfield port of Amble in Northumberland. Although these came to nothing, the idea was revived in a different form by Rennie's son, John Rennie the Younger, a few years later.

The City of Port Washington maintains twenty-nine public parks with amenities including picnic shelters, baseball and softball fields, tennis courts, nature preserves, and a public pool. The parks and recreation department offers recreation programs for residents and facilitates men's basketball and softball leagues as well as women's volleyball and fastpitch leagues. The Port Washington marina is open for recreational boaters from April through November. Fishers can also use the breakwaters to catch lake trout and Chinook salmon.

View northeast across Balaclava Bay from the Isle of Portland towards the southern and eastern entrances of Portland Harbour. The dark colour of the water between the two breakwaters is the position a scuttled battleship, . Balaclava Bay is a bay situated on the edge of Portland Harbour, where the breakwater meets the island, at the northern end of the Isle of Portland, Dorset, in southern England. The bay is part of the Jurassic Coast, a World Heritage Site.

Other facilities in Adak include three deep water docks and fueling facilities. The city has requested funds to greatly expand the Sweeper Cove small boat harbor, including new breakwaters, a dock and new moorage floats . There are approximately of paved and primitive roads on Adak, all privately owned by the Aleut Corporation. The Aleut are also seeking to develop their water system, which has been well-maintained and -designed for a larger Naval population, as an export industry.

Manistique, formerly Monistique, is the only city and county seat of Schoolcraft County in the U.S. state of Michigan. As of the 2010 census, the city population was 3,097. The city borders the adjacent Manistique Township, but the two are administered automously. The city lies on the north shore of Lake Michigan at the mouth of the Manistique River, which forms a natural harbor that has been improved with breakwaters, dredging, and the Manistique East Breakwater Light.

North Mole, Detached Mole, and South Mole Bay of Gibraltar c1750 includes Gibraltar Harbour with Old Mole and short New Mole. The "New" Mole in the 1890s. Photograph taken from the "New" Mole looking south along its length in the 1890s . The South Mole at Gibraltar Harbour is one of a trio of breakwaters that provides protection to the harbour, in addition to that which results from the presence of the Rock of Gibraltar on its east side.

In France, DEME companies completed the Port 2000 extension project in the Port of Le Havre. The €218 million contract involved a total dredged volume of over 45 million m3; construction of 10 km of breakwaters; and 78 ha of land reclamation. Marine works were executed in tides of up to 8 m and strong currents of up to 5 knots. On the Mediterranean coast of France, DEME finished the Fos2XL extension at Fos-sur-Mer.

In the 1970s the port was greatly improved: now the port of Tripoli contains many cargo terminals, and is capable of servicing many ships at once. The port also features a yacht club, and a fishing wharf. The "Socialist Ports Company" is the port authority responsible for managing and operating the Port of Tripoli, which handled general and bulk cargoes and passengers. Protected by two breakwaters of 2000 and 700 meters, the harbor covers about 300 hectares.

The Port of Constanța is located in Constanța, Romania, on the western coast of the Black Sea, from the Bosphorus Strait and from the Sulina Branch, through which the Danube river flows into the sea. It covers , of which is land and the rest, is water. The two breakwaters located northwards and southwards shelter the port, creating the safest conditions for port activities. The present length of the north breakwater is and the south breakwater is .

An estimated 197 million people who live both below 10 m elevation and within 50 km of a reef consequently may receive risk reduction benefits from reefs. Restoring reefs is significantly cheaper than building artificial breakwaters in tropical environments. Expected damages from flooding would double, and costs from frequent storms would triple without the topmost meter of reefs. For 100-year storm events, flood damages would increase by 91% to $US 272 billion without the top meter.

After leaving the military, Crosby went to work as a civil engineer building breakwaters and lighthouses. During this time he help found the Westchester Polo Club and, in 1875, won an international pigeon-shooting contest. On July 20, 1876, Crosby was with Vice-Commodore William T. Garner of the New York Yacht Club on the Mohawk when a sudden squall overturned the yacht. He was later presented a medal for his heroic efforts to save lives during the event.

The port is located at the western shores of the Odessa Bay. It consists of several harbors which are divided one from another by a number of jetties, while the port itself is screened off from the open sea by few long breakwaters located in the Odessa Bay. Just around the southern jetty (Karantyny) located a passenger terminal with a multi-story hotel at the Nova jetty. Towards the middle there is a Ship Maintenance Factory "Ukraina".

Windfarm construction in alt=Image of harbour with windfarm construction The Port of Lowestoft is a harbour in Lowestoft in the English county of Suffolk owned by Associated British Ports. It is the most easterly harbour in the United Kingdom and has direct sea access to the North Sea. The harbour is made up of two sections divided by a bascule bridge. The inner harbour is formed by Lake Lothing whilst the outer harbour is constructed from breakwaters.

Cargo losses were high, close to 90 percent, in addition to pilfering with several goods from the ships often taken to the nearby evening bazaar. A iron-screw pile pier capable of berthing larger vessels was built perpendicular to the shore in 1861. However, the storms of 1868 and 1872 made the initial piers inoperative. In 1875, Edward VII laid the foundation stone for a new port, and the masonry work for L-shaped breakwaters was started in 1876.

The beach generally disappears over a period that ranges from months to decades. Groynes and breakwaters that run perpendicular to the shore protect it from erosion. Filling a breakwater with imported sand can stop the breakwater from trapping sand from the littoral stream (the ocean running along the shore.) Otherwise the breakwater may deprive downstream beaches of sand and accelerate erosion there. Armoring may restrict beach/ocean access, enhance erosion of adjacent shorelines, and requires long- term maintenance.

After years of false starts, changing designs, and petitioning the federal government for funding, an inner harbor design was finalized that also included improvements to the outer harbor and breakwaters. Currently Jones Island is home to the Port of Milwaukee, the Milwaukee Metropolitan Sewerage District's primary wastewater treatment plant, and other municipal services. It also supports the Hoan Bridge, a long span bridge. The land is heavily industrialized and only contains a couple of mature trees.

At the time, Max Perutz thought the ideas were practical and that the preceding research on pykrete was sufficiently advanced to allow Pyke's plan to be executed.. The plan was not put into action, but for the allied invasion of Normandy a system of preconstructed concrete breakwaters and landing stages called Mulberry was employed. Pyke's plans hint that he had some knowledge of the Mulberry plans, perhaps through his contacts with Bernal, who was one of Mulberry's progenitors.

In addition to the town's 14 hotels there are numerous bars and restaurants and a main shopping street. Along the Cala Bona seafront are three rocky beaches protected by artificial breakwaters. The town's sandy beach has a length of 550 metres and a width of 9 metres, and is located south of the harbour. The main beach has been certified by AENOR to UNE 170001 standard for universal accessibility, making it suitable for people with disabilities.

The lighthouse from the Old South Pier was removed to Roker seafront in 1983. Designed by Thomas Meik, it dates from 1856 From 1717 the newly formed River Wear Commission began to improve the harbour entrance at the mouth of the Wear. By 1750 a pair of breakwaters had been built (which survive in truncated form as the 'Old' North and South Piers). By the beginning of the next century each had a lighthouse at its end.

Tangasseri is a picturesque seaside village with a three kilometre long beach on which stands a 144 feet tall lighthouse—a silent sentinel warning seamen since 1902 of the treacherous reefs. There are also ruins of Portuguese and Dutch forts and 18th century churches. The fishery harbour at Tangasseri is a basin for traditional fishermen, achieved by the construction of two breakwaters. The length of the main breakwater is 2100 m and of the leeward breakwater 550 m.

It has an automated underground ammunition depot that allows ammunition to be loaded onto the ships and an automated warehouse system to store items. The base has a fibre optic broadband network for information management. The base was also designed to be environment-friendly, with small-scale wind turbines powering the lights along the breakwaters at night. Conventional roof construction materials were substituted by thin film solar panels and the solar energy generated lights the base.

The port, which includes an oil refinery, container handling facility, passenger area and numerous areas for handling dry cargo, is lucky in that its work does not depend on seasonal weather; the harbour itself is defended from the elements by breakwaters. The port is able to handle up to 14 million tons of cargo and about 24 million tons of oil products annually, whilst its passenger terminals can cater for around 4 million passengers a year at full capacity.

This species grows in shallow water on many kinds of hard surface including rocks, pilings, docks, breakwaters, seaweed, sea grasses, shellfish, floating debris and the hulls of ships. Other invertebrates and juvenile fish find suitable habitat around the colonies. The zooids feed by extending their lophophores and filter feeding, extracting particles less than in diameter from the water. The sea slug Okenia eolida feeds on fouling bryozoans including C. pallasiana, and has been transported around the world with them.

Hudson's equation, also known as Hudson's formula, is an equation used by coastal engineers to calculate the minimum size of riprap (rock armor blocks) required to provide satisfactory stability characteristics for rubble structures such as breakwaters under attack from storm wave conditions. The equation was developed by the United States Army Corps of Engineers, Waterways Experiment Station (WES), following extensive investigations by Hudson (1953, 1959, 1961a, 1961b) (see Shore Protection Manual and Rock Manual referenced below).

In winter, its typical habitat is rocky coasts but it also feeds on beaches, mudflats and man-made structures such as jetties and breakwaters. It uses its bill to turn over stones, algal mats and other objects to get at prey hidden beneath. It arrives on its breeding ground from early May to early June with the males arriving first. The birds often return to the same territory and pair with the same mate as previous years.

Since inhabited regions are not part of the national park, the land areas are nearly completely covered with salt marshes and a small part contains sandbars and dunes. The salt marshes cover over 10.000 ha, of which 70% developed on land protected by breakwaters, 10% are situated on the downwind side of the islands and the rest formed around the Hallig Islands. In between 1988 and 2001 the area of the salt marshes expanded about 700 ha.

The 12 Search and Rescue teams in the Portland area dealt with almost 1000 incidents in 2005. Portland lends its name to one of the BBC's Shipping Forecast regions. There are still two prisons on Portland: HMP The Verne, which until 1949 was a huge Victorian military fortress, and a Young Offenders' Institution (HMYOI) on the Grove clifftop. This was the original prison (HM Prison Portland) built for convicts who quarried stone for the Portland Breakwaters from 1848.

It was among the wealthiest, if not the wealthiest city in Roman Cyprus. The city had walled with towers disposed at regular intervals, and had a harbor (and although it was not of significant size, it was protected by two breakwaters and is still serviceable today). There was also an odeon and a theatre, and two large houses have been excavated. An agora has been found, but only the foundation exists today and excavations are still ongoing.

Byōbugaura is noted in Japan for its historical and ongoing marine erosion due to the geological character of the inlet and the near- constant violent waves of the Pacific Ocean in the area. About of land has been lost to erosion in the past 700 years. In modern times, in the 63 years between 1888 and 1951 of land have been lost. Tetrapods have been extensively installed at Byōbugaura to establish breakwaters, and have softened the retreat of land.

Bowcott's fascination with crumbling cars started when working on tow boats on the Fraser River in the 1980s. Farmers used cars as breakwaters to stop the river banks from eroding, leaving the cars in various states of ruin. Bowcott attempted to record his impressions of the decayed vehicles in paintings, but was dissatisfied with the results. After teaching at Capilano University for 22 years, Bowcott started working on the Trans Am Totem project for the 2014–2016 Vancouver Biennale.

The opening and closing of the gates is driven by a difference in water level on either side of the gate. Living Breakwaters Case Study The Living Breakwaters initiative is the result of an Obama-era competition for innovative designs to prevent further flooding in coastal communities during harsh weather conditions. In October 2012, Hurricane Sandy hit the east coast of the United States causing more than $65 billion in damages and economic loss. One of the areas that got hit hardest was Staten Island's South Shore where the beach community of Tottenville saw sixteen-foot waves that destroyed homes and killed two residents (Dejean). In response to the devastation, the Department of Housing and Urban Development created the Hurricane Sandy Rebuilding Task Force to develop “implementable solutions to the region's most complex needs (Hurricane Sandy Design Competition).” Shortly after its formation, the task force introduced Rebuild by Design, a competition that promised a total of $920 million from the Community Block Disaster Recovery program for the winners to implement their plans (Tottenville Shoreline Protection Project).

A six-kilometre channel was created from the city directly to the sea. In 1640 this was named the Grau du Roi, and although the name changed several times afterwards, it eventually reverted to its current name. In 1772 two breakwaters were constructed out of stone. After much subsequent work, it became a canal in 1845. There was an old lighthouse in the village which got a new copper lantern in 1828, and a second was constructed at l´Espiguette in 1867.

The piers are stone-filled timber cribs, wide, with the exception of the shoreward portion of the south pier, which is constructed of wooden pilings filled with sand. The original piers were wrapped in sheet piling in the 1950s-60s, and the entire structure capped in concrete; the piers now range from to wide. The lakeward sections of the breakwaters are stone-filled concrete, with riprap piled against the outside. The shoreward sections are wood pilings filled with stone and copped with concrete.

Construction began in October 1888 and by 1890 the project was three-quarters complete with of the rail bed finished, and of the track laid. A bridge and large stone arch culvert were built at Tidnish Bridge - a community which received its name due to this infrastructure. And the terminals were built including the docks, breakwaters, and lock. In fall 1890 the primary financiers of the project, Baring Brothers & Co., faced potential insolvency due to the financing of debts in Uruguay and Argentina.

From its inception in 1827 until the late 1850s, the lighthouse shared the peninsula with a thriving village of Long Point. By 1830, the lighthouse became the site of Long Point's first school, starting with only three children. The village grew to include the homes of 38 fishing families, a schoolhouse with up to 60 children, a post office, bakery, boat landings, breakwaters, and several saltworks which utilized windmills to pump seawater. For various reasons, the settlement was ultimately disbanded.

The bridge is located in an isolated, rural position at the end of a valley, crossed by the River Mira, whose margins are densely populated by forest and water lilies. It is an area of great natural landscape, situated near the Pousada de Santa Clara, Santa Clara dam and the community cemetery. The structure consists of stone and limestone masonry, plastered and whitewashed, with arched frames and breakwaters coated stone. The bridge, now ruined, still includes two arches with archivolts and masonry.

The remains of the original Tay bridge were demolished and replaced by an entirely new design by William Henry Barlow and his son Crawford Barlow. Some of the wrought iron girders were re-used in the new double track bridge by cutting them in half and re-welding to form wider structures for the track. The brick and masonry piers from the old bridge were left as breakwaters for the new piers, which were monocoques of wrought iron and steel.

Montrose Basin The Montrose Basin is a shallow estuary approximately three miles in diameter.N. W. H. Allsop, Breakwaters, Coastal Structures and Coastlines, Institution of Civil Engineers, 2002, Thomas Telford publisher, 520 pages It is situated where the River South Esk meets the North Sea. During the 16th century, local landowners desiring more arable land considered reducing its size, but their plans were never carried out. Rev. Mr. Alexander Molleson, "Town and Parish of Montrose", The Statistical Accounts of Scotland (1791-99), Vol.

A horizontal non-luffing jib was used, separate from the lower frame. This was supported on two carriages which could move sideways independently on curved tracks, thus allowing the jib to slew sideways over a small angle. For building linear breakwaters, this small slew angle was enough. With the load of these larger blocks, it was not yet possible to use a convenient central-pivot kingpost bearing, and full-circle slewing, as would be used for the much smaller Port Alfred crane.

After the construction of the St. Mary's Falls Ship Canal was completed at Sault Ste. Marie, ships carrying grain, lumber, coal, and iron ore could carry the natural resources of the Midwestern United States to East Coast ports. By the late 19th century the U.S. Army Corps of Engineers was tasked to create a bustling harbor at the western end of Lake Superior. For several years they created breakwaters, dredged channels, and built docks to accommodate ever-larger cargo-hauling ships.

The suburb is served by a retirement village on Military Road, a small shopping centre on Osborne Road. That has many retail stores and is home to a supermarket, a chemist and a Bakery as well as other restaurants and businesses. The western coastal side of the suburb contains a newly constructed Surf Lifesaving Club (completed in 2007), and the Gulf Point Marina which is home to a large sailing community. The marina, lined with exclusive houses, is protected by two artificial breakwaters.

The Port of Buchanan is located some 272 kilometers South-East of Monrovia. It constructed in 1960 by the Liberian-American Swedish Mining Corporation (LAMCO), a joint venture company, to export the iron ore deposits of the Nimba range. The Harbor is protected by two breakwaters, 1890 and 590 long respectively. Inside the basin, a 255 meters long ore loading quay is located adjacent to the deeper section of the harbor basin, providing a water depth of 12.95m below chart datum.

The port of Tema handles 80% of Ghana's import and export cargo, including the country's chief export, cacao. The port has of breakwaters, 12 deepwater berths, an outsize oil tanker berth, a dockyard, warehouses, and transit sheds. The port has open and covered areas for the storage of cargo, including a 77,200-m² (7.72-hectare) paved area for the storage of containers, steel products and other conventional cargo. The port's container yard is capable of holding over 8,000 TEUs at any given time.

The beach near the island is known as Rock Beach, after the tiny island opposite the beach. Until the breakwaters at the Rock Beach in Bat Yam were built in the late 1960s, the rock could only be reached swimming or sailing. Swimming there was and still is a common activity among bathers. The nature researcher and tour guide Yehuda Ziv wrote about the island: The legend and name were previously mentioned by Zev Vilnay, who dates these back to the Middle Ages.

Most of the season's storms arose from the subtropics. Nova Scotia was a focus for storm activity with four storms reaching the Canadian province as extratropical cyclones. Two of these were the remnants of hurricanes; the first inflicted $1.5 million in damage on the apple crop in the Annapolis Valley, and the second tore up four breakwaters and sank or grounded several ships. The year's deadliest tropical cyclone was a tropical storm that struck Florida at the end of August.

In order to achieve this, small structural modifications were made to the breakwaters that surrounded the island, allowing the sea water to move through the breakers without causing any damage to the island. To prevent erosion of the sand from the island, maintenance systems spray material along the coast of the island and also along the Dubai coast. Coastal ecology was recovered with the help of nature itself. These changes began attracting newer species of fishes and also reef formations.

Construction of the outer Harbour August 2007 The contract for the harbour construction was awarded jointly to Van Oord UK Ltd and Edmund Nuttall Ltd. The contract was worth in the region of £75m. The new harbour consists of construction of two breakwaters with a total length of approximately 1,400m, requiring the importation of approximately 900,000 tons of rock materials. There was dredging and subsequent beneficial reuse of approximately 1,600,000 m3 of sand to provide 17.6 ha of land for future port development.

So called "wild paths" promote erosion and are not to be followed. Where vegetation is tread upon, no roots are left to hold the sand and it will be removed by wind and water. The Wadden Sea on the east side between Sylt and the mainland has been a nature reserve and bird sanctuary since 1935 and is part of the Schleswig-Holstein Wadden Sea National Park. The construction of breakwaters in this area will abate sedimentation and is used for land reclamation.

Since then, the coastline has been improved to provide more beach for recreation, and a buffer from the power of a storm-driven oceans and hurricanes. The breakwaters are by no means a permanent fix and create problems of their own, influencing the movement of sand. The beaches and coastal areas are by nature unstable. After Hurricane Isabel pounded on the coast of Norfolk in late 2003, Norfolk had to replenish the shore with of sand, costing the city around $3.8 million.

Retrieved 6 November 2013. The work was supervised by the hydraulic engineer Palle Bruun who had reported on harbours in the Faroe Islands."Palle Bruun", Dansk Biografisk Leksikon. Retrieved 6 November 2013. Skagen wharf The design consisted of two breakwaters some apart that stretched out to sea. With their outer extensions providing an entrance some wide, the harbour covered an area of almost . The basin was divided by two cross piers, creating an outer harbour and an inner harbour with an entrance wide.

Construction of MOSE was authorised by the "Comitatone" on 3April 2003 and the associated construction sites opened the same year. Work began simultaneously and continues in parallel at the three inlets of Lido, Malamocco and Chioggia. Work on the structural parts (foundations, mobile barrier abutments, gate housing structures), associated structures (breakwaters, small craft harbours, locks) and parts for operating the system (technical buildings, plant) is now at an advanced stage. Currently about 4000 people are employed in the construction of MOSE.

Stothert & Pitt Titan crane Block-setting cranes were required to lift a single large block in one lift, and to position it accurately. They also needed to reach a distance horizontally, but not to lift their loads high. Their working area was along the length of the breakwater, which had not yet been constructed at the time that most of the heavy masonry was put into place. Early breakwaters had been built from rubble or small boulders, dumped by hand from barges.

Stage One: Site Preparation and Clearance \- Clearing the site and preparing it for development. Stage Two: Main Construction \- Constructing the Power Station, including the nuclear reactor buildings and the majority of supporting buildings, facilities, plant and structures, the MOLF, and the two breakwaters. Stage Three: Commissioning and Operation \- Testing and operating the Power Station as well as the construction of radioactive waste storage facilities. Stage Four: Decommissioning \- Converting the site into an end state to be agreed with the relevant authorities and regulators.

The construction of the eastern breakwater water was a 24-hour operation with rock being tipped at a peak-time rate of a 40-ton truckload every three minutes. 800 ton crawler cranes mounted on portal crawlers were used to place the dolosse on the rubble mound breakwaters. The portal crawlers were constructed high enough to allow the haul trucks access to the construction face where back tipping and skip placement of rock was carried out on a 24-hour cycle.

The storm also produced waves which, combined with the storm surge, breached dykes protecting low-lying farmland in the Minas Basin and the Tantramar Marshes, sending ocean waters surging far inland to inundate farms and communities. Sailing ships in various harbors were tossed about and/or broken up against wharves and breakwaters which were also destroyed. Farmers trying to rescue livestock from fields along shorelines drowned after dykes were breached. There were at least 37 deaths between Maine, New Brunswick, and New York.

By 2011, the beach has become the destination for as many as 10,000 visitors per day, with an average annual net income of approximately $270,000. On July 23, 1947, the Chamber of Commerce endorsed the construction of breakwaters at each end of the beachfront, with the Narragansett Planning board recommending the construction of a 750-foot jetty to be constructed on the southern end of the beach, on March 11, 1949, to address erosion issues - an ongoing and historic issue for the beach.

A thin stretch of sand beach juts north-ward into the waters of Erie, separating Middle Harbor from the lake. Part of this beach was damaged in 1972 by a storm, washing away a large section of the two-mile (3 km) beach. The current beach is a much smaller area to the north of the park, where swimming is permitted. Four segmented offshore breakwaters have been constructed on the Northern section of beach, to sustain what is left of the sandy shoreline.

Morpeth is now a picturesque riverside town; the decline of the port and other local industries has resulted in the preservation of many of its 19th-Century buildings. The wharves and most of the port's warehouses are gone. The Outer Harbour at Port Kembla and its breakwaters remain, as a part of an enlarged port that has a major coal export terminal—located on the newer Inner Harbour—but all the old coal jetties are gone. Pelaw Main in 2007.

They will help collect shells to install as well as watch (and discuss) the progress of the ecosystem. The plan for Living Breakwaters is all encompassing. It includes the steps of reducing risk and fragility, building up ecology leading to greater biodiversity, and benefiting the surrounding area through community partnering. The oysters on the wall will create a strong and more natural barrier as a form of risk management for the rise in storm frequency and sea level rise with climate change.

In the Archaeological Inventory of County Cork, it is described as a road bridge over the Delehinagh River, with two semi-circular arches, roughly cut voussoirs, a pointed breakwater, and overflow channel to the south-west. Many of the surviving bridges in mid-Cork are originally constructed of stone, arched in shape, and late eighteenth or early nineteenth century in date. Typical features often include semi-circular arches and pointed breakwaters. Earlier bridges are often narrower, although some were widened at a later stage.

In addition to the excavation work, breakwaters, training walls, a bridge and a sand bypassing system were constructed. The channel is spanned by the four-lane Port Bouvard Bridge, used by approximately 40,000 vehicles per day, which is part of the Old Coast Road between Perth and the southern coastal townships. Major residential canal developments have been constructed off the channel, including the suburb of Wannanup, as well as a golf course. Since the opening of the channel no blue-green algal blooms have occurred.

The village of Torsvåg includes a village area on the island of Vannøya and also an area on the islet of Kåja, located just offshore. There is a causeway connecting the two places which forms a nice harbor surrounded by the fishing village. The breakwaters at the entrance to the harbor form a snug port at the threshold of the big seas. The Vanna fish processing plant, «Torsvågbruket», is located on Kåja island and Torsvåg Lighthouse is on the highest point of the island.

Similar harbours of refuge would be built at Alderney, Dover, Holyhead, and later (in response to the increased naval threat from Germany) at Peterhead. Dockyard Offices (left), built (as the Engineer's Office) by John Coode in 1848, extended to the west in 1910.Historic England Grade II listing: Dockyard Offices The extension to the right of the clock tower was added for FOST in 1988. Construction of the two breakwaters began in 1849 when HRH Prince Albert laid the foundation stone on 25 July.

Railway lines were an early feature at all these harbours. East London Harbour was surveyed by Sir John Coode in 1870 and breakwater construction began in 1872, under the supervision of resident engineer William Lester. The first of four stone quarries to supply rock for the construction of the breakwaters was opened in June 1872 and made use of convict labour and oxen-drawn rail trucks. Construction of the South Breakwater, on the west bank of the Buffalo River, was completed by August 1873.

SCAPE's green infrastructure solution will be implemented in three stages beginning in Tottenville, subsequently expanding to the surrounding areas, and to be completed in 2021 (Melcher). The plan aims to protect the South Shore of Staten Island from future storm damage, employing oysters to purify the water and restore the coastline. They claim that the breakwaters will protect the coastline from the intense storm conditions caused by climate change and the wave protection will reduce erosion which has greatly contributed to habitat loss in the area (Dejean).

That enabled the cleansing of the beaches and preparations to be made in order to open them again to the public for bathing. During that period, tombolo breakwaters were placed, causing significant expansion of the beaches allowing a greater number of people to enter. In the scope of the project, beach facilities were restored and reopened. in 2011 the municipality of tel aviv has restored and renovated the promenade and today it runs from the port of tel aviv to the port of jaffa.

Before the Plymouth Breakwater was completed in 1841 and the Mount Batten Breakwater in 1881, the Mount Batten peninsula was subject to significant coastal erosion. In the 17th century, maintenance of the Cattewater required annual removal of silt and rubble which was dumped on the south side of Mount Batten. However, in 1633 and 1634 the Mount Batten isthmus was breached. A sea wall was built to resolve the problem but it wasn’t until the breakwaters were built that the problem was finally solved.

They also disrupt the long shore transport of sediment through the construction of piers, marinas or groynes, breakwaters and other hard structures. Excavating, building roads, houses and walkways on coastal dunes or beaches also causes sand dune erosion by disrupting natural sediment processes. Effective management of coastal dune systems must consider natural processes as a normal part of the natural environment as well as controlling human activities and seeking to alter natural processes should be kept at a minimum in order for restoration to be successful.

The Delehinagh River meets with the Dripsey River a short distance to the right of the bridge. The Archaeological Inventory of County Cork describes it as a road bridge with three arches, varying in shape and width, but generally semicircular. The bridge was said to possess dressed sandstone voussoirs, corbels on its piers which supported arch-centring during construction, and low pointed breakwaters on its upstream side. Pointed arches were an important feature of later Gothic Revival architecture, and said to be also present at Colthurst's Bridge.

The port also contains two bars and one restaurant which are frequently visited by locals and tourists. Additionally the only gas station on the island is situated here and is supplied by Royal Dutch Shell. Fort Bay has been affected by several hurricanes over the years, including breakwaters damage in Hurricane Lenny in 1999, one of the piers being destroyed by Hurricane Omar in 2008, and the fisherman's pier being damaged by Hurricane Irma and later destroyed by Hurricane Maria in 2017.Durand, Hazel.

According to the Italian bridge builder Gazzola, the Pont sur la Laye dates from the end of the 1st or beginning of the 2nd century AD, thus belonging to a round dozen known Roman segmental arch bridges. Structurae, though, ascribes an early Romanesque origin to the structure (11th century). Following the Mane homepage, the two side arches, along with their breakwaters, were added as late as the 17th century,Homepage of the town of Mane which means that the segmental arches are of a relatively late date.

SCAPE's role in the harbor-wide study was to integrate natural systems as risk-reduction infrastructure, and layering strategies for enhanced coastal protection and ecosystem health. The project was awarded an ASLA-NY honor award in 2014. In 2014, SCAPE was recognized as the winner of the Rebuild By Design competition in order to preserve communities after Hurricane Sandy in 2012. SCAPE's winning project was a play off of Oyster- tecture called "Living Breakwaters" and was meant to reduce erosion on the shoreline of Brooklyn, New York.

Tests were performed by the Corps of Engineers to determine how to maintain the island and not allow it to dissipate into the bay. A triangular shape was designed and floating tire breakwaters were used to protect the island from erosion due to wave action. Marsh plants were used to develop an established root system to assist with long term integrity of the island. This was a state-of-the-art technique which has been widely studied, found to be effective and is now used nationwide.

Patea has retained a strong community focus and enjoys many services including a well-resourced medical centre, public swimming pool and trust-owned rest home. The town is also the location of Aotea Utanganui - Museum of South Taranaki. The breakwaters at Patea were started in 1878 and are being refurbished by the South Taranaki District Council. Patea and surrounding community has a South Taranaki District Council LibraryPlus, which provides a full library service and Council-related services, including dog registration, payment of rates, and building permit enquiries.

It was also in the process of acquiring title between Beach 25th and 59th Streets in Edgemere and Far Rockaway, and between Beach 75th and 109th Streets in Hammels, Hollands, and Seaside. The New York City Board of Estimate appropriated $8 million for a beach improvement project on the Rockaway peninsula in June 1925. The Queens borough president's office started soliciting bids to build "bulkheads, groynes, jetties and breakwaters" and to add sand to the southern shore of the Rockaway peninsula between Beach 59th and 109th Streets.

The most intense winds were likely confined to the sparsely populated shoreline east of Mutarnee; there, tree damage was significant, and a few beach huts were damaged. Along the coast, rough seas washed ashore and wrecked several boats. The Port of Townsville sustained $1.1 million in damage, which included the destruction of breakwaters. Coastal installations along the Strand were also damaged by the rough seas, while the onshore winds blasted tree trunks with sand from the beaches and left up to of accumulated sand in car parks.

Gibraltar Harbour with South Mole (left), Detached Mole (center), and North Mole (right) Gibraltar Harbour (pictured), also known as the Port of Gibraltar, is on the west side of the British Overseas Territory of Gibraltar, at latitude 36º09'N, and longitude 05º20'W. In addition to the natural protection provided by the Rock, there is a set of man-made defences. These include three breakwaters: the North Mole with its Western Arm, the Detached Mole, and the South Mole. The port has north and south entrances.

By July 1943 a mathematical theory to support the approach had been evolved and in August 1943 experiments began in Portsmouth. The breakwaters were and , with gigantic airbags divided into three compartments separated by canvas walls proofed with rubber. Later that summer, Lochner and his fellow scientists flew to Canada for the Quebec Conference to report the progress of the harbours to Franklin Roosevelt and Winston Churchill. The decision to go ahead was taken and full- scale trials of the floating breakwater started in April 1944.

To the west of Flagstaff Point is Belmore Basin and Brighton Beach. Belmore Basin is the man-made section of Wollongong Harbour and was built using convict labour and is a heritage site with plaques along a history walk. There are two eastern breakwaters, a small stubby one of cement topped stone for the old lighthouse, and a large artificial boulder one with a light at the end for aiding ships in fog. At the portside is the fish market and a number of restaurants.

During the frozen winter of 2010–11, the Port authorities estimated that there were 16 ships with icebreaking capabilities available, 10 of which belonged to the TTLC. CNOOC Bohai had 24 icebreakers, needed to clear offshore platforms, and also lent two larger icebreakers to the Port. Port Construction: The Port's main construction and engineering outfit is CCCC First Harbor Engineering (中交第一航务工程局有限公司). Four subsidiary companies carry out all forms of project engineering and construction, from roads to breakwaters.

The rehabilitation of the abandoned St. Joseph's Chapel received an Award of Merit as part of the 2005 UNESCO Asia-Pacific Heritage Awards.2005 UNESCO Asia-Pacific Heritage Award Cardinal Zen held a special mass in the chapel on 7 May 2006.RASHKB/AMO Volunteers Conservation Newsletter (May 2006) The Yim Tin Tsai Typhoon Shelter, established in 1968, is located at the east of the island. It is bordered on the east by the northern part of Kau Sai Chau, and by breakwaters in the north and south.

Towards the end of the war he collaborated on the work on floating breakwaters which were used in the Normandy landing. After the war he resumed his work on geomagnetism, developing the theory of induction in thin sheets. In 1969 he was awarded the Gold Medal of the Royal Astronomical Society for his work on geomagnetism, especially for his study of the electrical conductivity of the earth's core. The Price Medal, awarded annually by the Royal Astronomical Society for outstanding work in geophysics, is named in his honour.

View of the harbour from above Staithes North Yorkshire A street in Staithes Staithes rooftops Staithes has a sheltered harbour, bounded by high cliffs and two long breakwaters. A mile to the west is Boulby Cliff where, for a brief period, alum, a mineral used to improve the strength and permanency of colour when dying cloth, was mined. The mining operation ended when a cheaper chemical method was developed. The ruined remnants of the mines can be seen from the cliff top when walking the Cleveland Way between Staithes and Skinningrove.

Port Washington's historic downtown in the central part of the city is in the Sauk Creek valley, at a lower elevation than the rest of the city. The valley is a break in the bluffs, providing easy access to the lakeshore, which attracted early settlers to the area. Port Washington's artificial harbor, dredged in 1871 with subsequently constructed breakwaters, is located at the mouth of Sauk Creek, adjacent to downtown. The city is located in the Southeastern Wisconsin glacial till plains that were created by the Wisconsin glaciation during the most recent ice age.

According to the famous historian Dr A S Altekar, Gopakapattana finds mention in the epic, Mahabharata. It was also known as Govapuri or Gove in the Ramayana, which adds that whoever casts a glance over the holy city of Govapuri gets his sins cleansed. As the Kadamba dynasty prospered, they built a navy that was formidable. With Chandor being too small to accommodate his fleet of ships, Kadamba ruler Jayakeshi I moved to Goa Velha or Gopakapattana which had natural breakwaters, a safe cove and was open to the seas, historians recount.

The Detached Mole at Gibraltar Harbour, is one of a trio of breakwaters that provides protection to the harbour, in addition to the protection resulting from the presence of the Rock of Gibraltar itself on the east side of the harbour. The Detached Mole is positioned at the western aspect of the middle section of the harbour, which is located just north of the east entrance to the Strait of Gibraltar. The Detached Mole is 800 metres in length. Yachting facilities, including the Queensway Quay Marina, are also in the middle section of the harbour.

In fluid dynamics, the Iribarren number or Iribarren parameter – also known as the surf similarity parameter and breaker parameter – is a dimensionless parameter used to model several effects of (breaking) surface gravity waves on beaches and coastal structures. The parameter is named after the Spanish engineer Ramón Iribarren Cavanillas (1900–1967), who introduced it to describe the occurrence of wave breaking on sloping beaches. For instance, the Iribarren number is used to describe breaking wave types on beaches; or wave run-up on – and reflection by – beaches, breakwaters and dikes.

By the middle of the 18th century, the Haven was a busy port, exporting oysters, salt, local glassware, ceramics, bricks, fireclay, coal, and chemicals, including sulphuric acid. Imports were brandy from France, port wine from Portugal, Delft china from the Low countries, leather from the Baltic port Danzig, and furs from Canada. A map of 1773 shows the port having two breakwaters. The importance of the Haven is reflected in the fact that it has customs jurisdiction over the coastline from Figgate Burn, Portobello all the way to the Tyne at Belhaven.

Defensive breakwaters were constructed in front of both to prevent an armoured enemy ship ramming the walls.Hughes & Migos, p. 91 Gibraltar's guns were reorganised and upgraded from 1856. Many of the 24-pounder guns were replaced with 32-pounders and the retired batteries were equipped with 68-pounders. A wide variety of old guns was still in use, including iron-cast 6-, 12- and 18-pounder, which complicated the supply and maintenance of the batteries. At its peak, the fortress had 681 guns in 110 batteries and positions.

On Weymouth's side of the harbour, the Nothe Fort was built at the end of the Nothe Peninsula, and completed in 1872. In 1892, the Verne High Angle Battery was built in a disused quarry near the Verne Citadel, but was decommissioned in 1906. As part of further defence works against the threat of torpedo attack, construction of the harbour's two northern breakwaters was carried out between 1893-1906. In 1902, additional defences were constructed, including Upton Fort at Osmington and Blacknor Fort on the western side of Portland.

Also, large lumps of lime were found in all five of the cores studied at Caesarea, which shows that the mixture was not mixed thoroughly. However, stability would not have been seriously affected if the harbour had not been constructed over a geological fault line that runs along the coast. Seismic action gradually took its toll on the breakwaters, causing them to tilt down and settle into the seabed. Also, studies of seabed deposits at Caesarea have shown that a tsunami struck the area sometime during the 1st or 2nd century.

Adjacent to the loading quay, a waiting berth for ore carrier is available. On the inner side of the secondary breakwater, a commercial quay 334m long is located with an available water depth of 10.15m below chart datum. The access channel to the port provides ship a water depth of 14.95m below chart datum and a channel width between the breakwaters of 210m. The Port of Greenville is also located in the South-eastern region of the country, Sinoe County, about 421 miles from the Freeport of Monrovia.

On the successful completion of the Jebel Aulia Dam, Gibson became managing director of Pauling & Co., a position he held until his death in March 1947. During the Second World War Paulings undertook construction work for the war effort, including Royal Ordnance factories, and they were one of the 25 principal civil engineering contractors to build the Phoenix concrete caissons that formed the breakwaters to the Mulberry harbours.Hartcup, p. 94 In 1946 Pauling & Co. were employed by United Africa Company to undertake ground clearance for the ill-fated Groundnut scheme.

In 1664 a simple pier was built out of poles, but it was too small to provide protection for the galleys that were on the lake. The Bernese government therefore decided to build a commercial and military port in Morges and not in Lausanne-Ouchy. The current port was built with two curved breakwaters between 1691–96 and in 1702 the customs house was finished. With the port, Morges became the starting point for several trade routes and became the site of a major transshipment point for goods such as salt, wine and grain.

It is a protected harbor that developed as a trade port and shipbuilding center in the 18th century. It is now primarily a recreational harbor, having been superseded by the Bridgeport Harbor, which was enlarged by substantial breakwaters in 1907. St. Mary's by the Sea walkway at Black Rock Harbor in Bridgeport Cedar Creek and Black Rock Harbor as seen from I-95 St. Mary's by the Sea is a residential walkway along Long Island Sound. Outdoor enthusiasts to enjoy bringing binoculars to watch the birds and wildlife here.

The bridge, the largest and best known of its kind in the Rhodopes, is 56 m (183.7 ft) long and has three arches, but also features holes with small semicircular arches to read water level. The Dyavolski most is 3.5 m (11.5 ft) wide and its main arch is 11.50 m (37.7 ft) high. A stone parapet, 12 cm (4.7 in) tall, is preserved on the sides, and breakwaters are placed opposite the stream. International long-distance hiking trail the Sultans Trail passes the bridge from Ardino to Kardzhali.

Increasingly congested traffic on Highway 101 and the proximity of job centers (including Genentech) near this marina led the San Francisco Bay Water Transit Authority to develop a ferry terminal here. During the planning phases it was proposed that the terminal operate service to downtown San Francisco as well as Bay Farm Island in Alameda on the opposite shore. Service was to begin in 2011. Two docks were removed for the new ferry terminal, built on pilings and floats, and the Army Corps of Engineers set up breakwaters in order to allow safe ferry operations.

In addition, wedge- shaped breakwaters were added on the piers, although not all piers feature them on both sides. The clear spans of the three central arches have been determined at 23.52 m for the central arch and 14.95 m for the two flanking arches, while the two piers supporting the central arch were measured at 9.60 m. The gaps in the right end of the structure reveal the hollow chamber construction method of the bridge deck, typical of several Roman bridges in Asia Minor, e.g. the Aesepus Bridge.

Simulation of wave penetration—involving diffraction and refraction—into Tedious Creek, Maryland, using CGWAVE (which solves the mild-slope equation). In fluid dynamics, the mild-slope equation describes the combined effects of diffraction and refraction for water waves propagating over bathymetry and due to lateral boundaries—like breakwaters and coastlines. It is an approximate model, deriving its name from being originally developed for wave propagation over mild slopes of the sea floor. The mild-slope equation is often used in coastal engineering to compute the wave-field changes near harbours and coasts.

These half-open spandrels were meant to further relieve the dead load on the bridge. The retaining walls, just as the breakwaters, were built with carefully hewn limestone blocks. The outer voussoirs of the arch rib are built of alternating bricks and ashlar stones, while the rest of the arch vaults consists entirely out of bricks. Further materials mentioned by Wiegand include marble – probably for facing – and mortar, which could have been used as a binder, or may refer to Roman concrete which often served to fill the interior of the spandrels and the piers.

Most shipments were brought in over the beaches until the port of Cherbourg was cleared of mines and obstructions on 16 July. The most important use of the Mulberry harbour was the unloading of heavy machinery that could not be brought across the beaches. Artificial breakwaters (Gooseberries) sheltered hundreds of ships during the storm of 17–23 June, and provided shelter for craft unloading stores at Juno and Sword. A joint Anglo-American oil depot was constructed at Port-en-Bessin, fed via buoyed pipes known as "Tombola" from oil tankers moored offshore.

The National Harbor of Refuge and Delaware Breakwater Historic District encompasses a series of seacoast breakwaters behind Cape Henlopen, Delaware, built between 1828 and 1898 to establish a shipping haven on a coastline that lacked safe harbors. The Harbor of Refuge is at the mouth of the Delaware Bay estuary where it opens into the Atlantic Ocean, at Lewes. The district is almost entirely offshore, touching land only at the former United States Coast Guard station. It was added to the National Register of Historic Places in 1989.

This siting was accomplished by creating a platform linking a natural rock outcrop reclaimed from the sea, where a swimming pool had previously been located. Two large breakwaters were also built, to protect the mosque from the erosive action of the ocean waves, which can be up to in height. A temporary pier in length had to be erected to protect the foundations of the pillars from the sea during the construction period. Its environmental advantage is that it is free of noise and pollution and receives a fresh breeze from the sea.

Breakwaters function much like seawalls, except that they are not manmade, they are made from large formations of rocks stacked near each other. They are not as effective as seawalls in stopping water from reaching the coast, however, they allow seawater to bring sediment within its barrier, but stop the retreating water from removing sediment, thus helping coastlines build up and replenish. Estimates are that the area will continue to erode, in part due to a dearth of plant nutrients. Solutions are numerous; however, governments and organizations have problems implementing them.

The mouth of the slough should be kept open by periodic dredging as blockage causes eutrophication. The Northern Gold Coast Beach Protection Strategy is an example of a successful execution of this technique. Between 1992 and 1999, the Gold Coast City Council worked with experts on a proposed plan to stop beach erosion. Options originally considered included groynes, breakwaters, and others but the City Council finally chose to dredge sediment from the nearby Gold Coast Broadwater, pump it through large pipes, and deposit it along five kilometers of coast.

These mobile breakwaters would protect the landing craft and troops from the Atlantic rollers. In 1943, he was released from his Royal Navy work, and went to the physics faculty of the Imperial College London, his alma mater. Then he joined Tube Alloys the secret nuclear weapon directorate, and shortly before D-Day in 1944, Penney was made head of the British delegation to the Manhattan Project, when a large team of British scientists joined the American atomic bomb project. Penney and others went to the Los Alamos Laboratory.

The large princely states, Hyderabad, Mysore, Travancore, and Kashmir, as well as the smaller ones of Rajputana, did not join the rebellion, serving the British, in the Governor-General Lord Canning's words, as "breakwaters in a storm." In some regions, most notably in Awadh, the rebellion took on the attributes of a patriotic revolt against British oppression., However, the rebel leaders proclaimed no articles of faith that presaged a new political system. Even so, the rebellion proved to be an important watershed in Indian and British Empire history.

"Estuary by Ted Walker", The New Yorker, 11 April 1964, p. 46. Other key influences on his literary development included the Welsh poet Leslie Norris and canon of Chichester Cathedral, the Scotsman Andrew Young, both near neighbours, as well as the critic Robert Gittings. Walker's first book of verse, Fox on a Barn Door, focused on the Sussex countryside and coast. The titles of a good third of the poems – such as "Breakwaters", "The Skate Fishers" and "On the Sea Wall" are about the shoreline of Lancing and Shoreham.

Less than two weeks after Marie, Hurricane Norbert threatened to bring further increased surf to the area. With the breakwater yet to be repaired, a large sand berm was reinforced along beaches and residents were supplied with sandbags. Repair work along the Middle Breakwater on October 29 The Army Corps estimated that it would take more than $20 million to repair just the major breaches along the middle breakwater. On September 18 Connolly- Pacific Co. was contracted for $5m to repair the twelve worst affected areas of the breakwaters and construction began on October 8\.

At present there are 14 berths with capacity of 33.34 million tonnes per annum (MTPA), all situated within two breakwaters in V. O. Chidambaranar Port Trust. The Port which began with the mono commodity of coal for the Thoothukudi Thermal Power Station has diversified and the cargo profile of the Port consists of import cargo, viz. Thermal Coal, Timber Logs, Petroleum Products, LPG and various other bulk, break bulk and containerized cargoes and export cargoes viz. Granite, Salt, Sugar (Raw) Cement in bags, containerized cargo and construction materials.

273 but its outfitting continued as well. From April to July 1868, four new wharfs were built between the Ikuta and Uji rivers, and construction was carried out between 1871 and 1872 on breakwaters and expanding the wharves. From April 29 to July 26, 1871, further construction redirected the Ikuta River—not only to prevent the flooding of the settlement, but also to stop the flow of sediment into the middle of the harbor. These actions laid the foundations for the Port of Kobe's later reputation as a good natural harbor.

The harbour was made by the building of stone breakwaters between 1848 and 1905. From its inception it was a Royal Navy base, and played prominent roles during the First and Second World Wars; ships of the Royal Navy and NATO countries worked up and exercised in its waters until 1995. The harbour is now a civilian port and popular recreation area, and was used for the 2012 Olympic Games. The name Portland is used for one of the British Sea Areas, and has been exported as the name of North American and Australian towns.

The railway originally ran down the street (left) directly onto the harbour breakwaters at Saundersfoot There were worthwhile deposits of high quality anthracite in the Saundersfoot area; part of the Pembrokeshire Coalfield. To move the extracted coal to the coast for onward shipping transport, a tramroad was proposed. The Saundersfoot Railway and Harbour Company was formed in 1828 to build a harbour at Saundersfoot and a tramway to connect it to the collieries around Begelly and Stepaside. In 1829, Parliamentary authorisation was given for the Saundersfoot Railway and Harbour Company.

A catwalk at Praia do Cassino. Bathers on the Praia do Cassino. Praia do Cassino (Portuguese for Casino Beach) is the southernmost beach of the Brazilian coast (), on the South Atlantic Ocean, in the state of Rio Grande do Sul. It is thought to be the longest uninterrupted sandy seashore in the world, with various sources measuring it from to , stretching from the Molhes (breakwaters) at the entrance of the Rio Grande seaport in the north to the mouth of the Chuí Stream, on the border with Uruguay, in the south.

The southern coalfields could be worked profitably, if the problem of shipping could be solved. The absence of a suitable port held back development of the southern mines, until around 1849 when the Mt Kiera mine opened. Coal from the southern coal fields, at various times, was loaded at Wollongong Harbour and Port Kembla and at the ocean jetty ports: Bellambi; Coalcliff; Hicks Point at Austinmer; and Sandon Point, Bulli. Port Kembla was originally an ocean jetty port but two breakwaters were added later to provide shelter. Thirroul.

At the beginning of the 20th century, Manistique was a boom town, with timber and pig iron shipping from the harbor daily. However, the harbor itself was protected only by timber crib piers originally constructed in the 1870s. However, by 1910, leaders in Manistique managed to convince the Federal government of the financial importance of the harbor, and an Army Corps of Engineers harbor expert was sent to Manistique to draw up plans for a concrete breakwater structure. The contract to construct the breakwaters was awarded to the Greiling Brothers Company, and construction was started in 1910.

The harbor quickly became a popular refuge, and in 1867, Congress directed the Army Corps of Engineers to begin improvements on the harbor. A new channel was cut, and by 1873 two new wooden piers had been constructed and a beacon installed at the pierhead. As the harbor became more utilized, the piers were extended in 1884 and again in 1896, and a new lighthouse (the Frankfort Light, also on the National Register of Historic Places) was installed on the north pier in 1912. In 1928, construction began on a pair of concrete breakwaters at the harbor entrance.

In 1930 the Milwaukee Electric Railway & Light Company decided to build a $30 million steam-electric power plant south of the old shipping channel. That plant required a larger harbor to land ships carrying coal. In 1931 funds were provided to improve the harbor under the Works Progress Administration; Construction was protracted and the new breakwaters took three years to complete. As an addendum to this project a new light was constructed, identical to that built at the same time at the Indiana Harbor East Breakwater Light and a design at several other sites in the Great Lakes.

Warry, pp. 159–172 The power of Roman field camps has been noted earlier, but in other actions, the Romans sometimes used trenches to secure their flanks against envelopment when they were outnumbered, as Caesar did during operations in Belgaic Gaul. In the Brittany region of France, moles and breakwaters were constructed at enormous effort to assault the estuarine strongholds of the Gauls. Internal Roman fighting between Caesar and Pompey also saw the frequent employment of trenches, counter-trenches, dug-in strong points, and other works as the contenders manoeuvred against each other in field combat.

Another caltrop- like defence during World War II was the massive steel, freestanding Czech hedgehog; the works were designed as anti-tank obstacles, and could also damage landing craft and warships that came too close to shore. These were used by the Germans to defend beaches at Normandy and other coastal areas. Tetrapods are concrete blocks shaped like caltrops, which interlock when piled up. They are used as riprap in the construction of breakwaters and other sea defences, as they have been found to let the water pass through them and interrupt natural processes less than some other defenses.

32 The Romans built new breakwaters and the base was fed by the Aqua Augusta (Naples), an aqueduct which also supplied Cumae, Neapolis, Pompeii and other towns around the bay. The outer harbour behind Cape Misenum served the active vessels of the Roman navy and provided room for training exercises, while its inner counterpart (to which it was connected by a canal crossed by a wooden bridge) was designed for the reserve fleet and for repairs, and as a refuge from storms. Because of its location, the area controlled the entire Italian west coast, the islands and the Straits of Messina.

View of Pt Kembla from No.1 Coal Jetty in 1919. The closest chimney is the power station supplying the electrically-powered equipment on the jetty.In its earlier years—much like the other ocean jetty coal ports—Port Kembla's two coal jetties were exposed to rough seas during bad weather. The new breakwaters of the Outer Harbour not only provided a reliably safe anchorage but also protected the jetties structures from damage. In 1906, the North Bulli Company won the right to use Port Kembla to ship its coal, dooming its Hick's Point Jetty at Austinmer.

The current (2009) foreshore, dominated by man-made breakwaters and thus relatively inhospitable Onehunga's shore is heavily modified by human use. The old volcanic basin that used to link to the Manukau Harbour was filled in, with shorelines reclaimed and straightened for human use (Port of Onehunga, industrial uses and sports fields). The New Zealand State Highway 20 extension further disrupted Onehunga's connection to the shore in the 1970s. This loss of amenity and space was one of the major complaints of local groups during negotiations over further motorway widening connected to the Mangere Bridge duplication.

The initial southern breakwaters were built between 1849 and 1872; meanwhile, various defences were created to defend the harbour. The Verne Citadel, designed by Captain Crosman R.E., was built at Verne Hill between 1860-81: the 56 acre fortress was designed for 1000 troops and had gun emplacements facing seawards on three sides. Below the eastern side of the citadel, East Weare Battery was built during the 1860s, along with the detention barracks East Weare Camp. On the end of the inner breakwater was the Inner Pierhead Fort, and on the outer breakwater the circular Breakwater Fort.

The harbours were made up of all the elements one would expect of any harbour: breakwater, piers, roadways etc. Mulberry B harbour "Port Winston" in September 1944 At a meeting following the Dieppe Raid, Vice-Admiral John Hughes-Hallett declared that if a port could not be captured, then one should be taken across the Channel. The concept of Mulberry harbours began to take shape when Hughes-Hallett moved to be Naval Chief of Staff to the Overlord planners. The proposed harbours called for many huge caissons of various sorts to build breakwaters and piers and connecting structures to provide the roadways.

The north-west side of the bay is dominated by the major Ferry terminal at which the railway and the A40 terminate and from which two ships a day sail to Rosslare Europort, Ireland. Inland from Goodwick are the two settlements of Stop-and Call and Dyfryn. Within the bay itself are two 1 km long breakwaters ensuring safe port moorings, and between the ferry terminal and the outer breakwater is the Fishguard Lifeboat Station. North of the outer breakwater the community boundary takes in the east coast of Strumble Head including the rocky headland of Pen Anglas.

Phase I of the project was completed, which consisted of the reconstruction of the waterfront park while maintaining the historical facade representative of St. Croix's heritage. Natural stonework was used throughout the project site in accordance with the local architectural style, enhancing the authenticity of the arrival experience. Phase II of the project, contemplated for the future, will involve the reconstruction of the community waterfront north of the fort and include the recreation of breakwaters, the reconstruction of Paul E. Joseph Stadium, and the restoration of the beach, restroom facilities, retaining pond, utilities, parking areas, and soccer fields.

With the help of the Great Coastal Hurricane of 1806, Willoughby Spit was formed. Over the course of the next centuries, general westward movement of sand was compounded by extensive erosion of the long beach of Willoughby Spit and the rest of Ocean View. Homes and businesses built too close to the water were routinely threatened by coastal storms, and recreational use was limited because of the narrow width of the beach. The City of Norfolk began implementing a "beach nourishment" construction project, which included the installation of breakwaters to try to reduce beach erosion and protect the shoreline.

The old brick and masonry piers from the first bridge were retained as breakwaters for the new piers upstream. They can still be seen today as a forlorn reminder of the tragedy of 1879. Barlow was an early experimenter with civil engineering uses for steel, carrying out research at Woolwich Arsenal in the 1850s and being a member of the Institution of Civil Engineers' committee on the subject. From 1873 he was a member of a Board of Trade committee which produced the first recommendations on safe working loads for steel in railway structures in 1877.

In 1926 he was posted to the Royal Navy dockyard in Malta where he was involved in the construction of a wave trap in the harbour and underground ammunition dumps as well as the maintenance of various breakwaters. He returned to the UK in 1929 when he took up a position as a civil engineer to the Portsmouth dockyard, where he was involved with the reconstruction of a seawall and jetty. Whitaker was promoted to Superintending Civil Engineer of the naval base at Singapore in 1933, whilst there he constructed a long dry dock and undertook reclamation works on swampy land.

In due course the longshore drift along the coast silted up the latter two ports, and also the mouth of the River Dour, Kent on which Dover stands. The Romans, for whom the port was a base for their navy, the ‘’Classis Britannica’’, constructed breakwaters against the sea‘s depredations, and added two lighthouses on the heights either side of the estuary. It is possible that they also constructed a fort on what is now the site of Dover Castle to protect the port. Dover became one of the three important towns in Kent, after Canterbury (‘'Durovernum'’) and Rochester (‘'Durobrivae'’).

The east and west piers of the harbour are each of long and enclose an area of with the harbour entrance being across. The glacis on the outer faces of the piers were designed to have a slope of 1 in 5 except for the lowest part increasing to 1 in 1 or 1 in two. The top of the pier had a width approaching two roadways, and this led to the width at the bottom on the seafloor being up to . The harbour is divided into four major inner harbours by various piers and breakwaters.

Nuclear Power Generation and Fuel Cycle Report 1997 p. 61. To be located offshore from the Little Egg Harbor and Great Bay (about northeast of Atlantic City), the plants were to be on man-made islands in the Atlantic Ocean. The islands themselves and the massive concrete breakwaters would be built in a factory on Blount Island near Jacksonville, Florida; they would then be floated by ship to the plant site. The plants were first envisioned in 1969 by an engineer at PSE&G; and the reactors were ordered in 1972 for operation starting in the mid-1980s.

The contractors built dams to connect each end of the island to the mainland, drained or pumped the water from the site and excavated it. They used the material to level the area around the docks and for the core of breakwaters to protect the entrance. The works included a basin with gates at each end which served as a lock between the sea entrance and the docks, the dock walls and quays, coal loading equipment and railways to deliver coal from the mines to the docks. A second dock and second entrance lock were added in 1898.

It is still an important component of the harbor facilities. In its current configuration, the canal is defined by a pair of breakwaters long and apart, constructed of concrete set on timber and stone cribbing. HAER No. MN-10 The canal is maintained at wide and LWD, allowing passage of ocean-going ships. Three lighthouses are placed on the sides of the canal: the Duluth North Pier Light and the Duluth South Breakwater Outer Light mark the lake ends of the canal, while the Duluth South Breakwater Inner Light functions with the south breakwater light as a range light.

The design of the dolos is usually credited to the South African Eric Mowbray Merrifield, one-time East London Harbour Engineer (from 1961–1976). In the late 1990s the claim of Aubrey Kruger gained more prominence. Kruger's claim is that he and Merrifield had considered the shape of concrete blocks to be used to protect East London's extensive breakwaters for the City's non-natural harbour, following a major storm in 1963. Merrifield wished to design a block that did not break up or shift when struck by the sea; that was cheap; and that did not require precise placement.

Landévennec, August 2006. In the background are two former escort avisos previously used as breakwaters at Brest, and in the left foreground is the Kometa. Colbert was the largest ship at the graveyard Shortly before entering the roadstead of Brest, the river Aulne forms a bend around the Île de Térénez then the pointe de Pen Forn near Landévennec, where there is 10m depth of water regardless of the tide and with the high surrounding hills blocking the winds and thus keeping the water calm. Here is sited a ship graveyard for civilian but particularly naval vessels.

Various and unique methods have been used for field measurements in the swash zone. For wave run-up measurements, for example, Guza and Thornton (1981, 1982) used an 80m long dual-resistance wire stretched across the beach profile and held about 3 cm above the sand by non-conducting supports. Holman and Sallenger (1985) conducted run-up investigation by taking videos of the swash to digitise the positions of the waterline over time. Many of the studies involved engineering structures, including seawalls, jetties and breakwaters, to establish design criteria that protect the structures from overtopping by extreme run-ups.

Pelumpong Spit Tanjong Pelumpong is located between the Brunei Bay to the south and the South China Sea to the north. Administratively, it is part of Mukim SerasaPoscode of the Brunei-Muara district of the Brunei-Muara district of Brunei and is separated from the mainland to the west by the 50m-wide, 10m-deep Muara cut. This channel is protected at each side by breakwaters which extend seawards towards the northeast.Pelumpong Spit, Muara - retrieved 28-05-2007 The northern coast of Tanjong Pelumpong consists of the white sandy beach similar to that of Muara Beach.

In addition to expansion of the outer harbour, proposed upgrades include construction of breakwaters and lengthening the approach channel. The port has been upgraded to handle vessels longer than 245 m.Tuticorin Port Expansion Plan The advantages of deploying bigger vessels are that the existing restriction on booking can be eliminated and the transshipment at Colombo port can be reduced. The Tuticorin port has the potential to be an international container transshipment hub given its unique geographical location.Tuticorin Port Potential Activity at the port has grown at a rate of 17 per cent per year over the last five years.

A 1887 project to improve the harbor facilities resulted in the construction of a pair of breakwaters to better enclose the bay, one jutting out from either shore. The eastern of the two was marked by a lantern mounted on an iron post, which was first lit in 1895 and then moved to the end of the breakwater upon its completion in 1902. At the same time the lantern was replaced with a Pintsch gas lamp supplied from a pair of tanks on the breakwater. Four years later, the lamp was replaced with the current tower.

After the war, Stewart was superintending engineer of the defenses of the Delaware River and Delaware Bay (1865-1870). From 1870 to 1886, he was a member of the board of engineers that planned the defenses of the Pacific Coast, a duty he carried out while serving as superintending engineer of construction of Fort Point, Point San Jose, and Angel Island in San Francisco Harbor. In 1872, Stewart supervised the removal of Rincon Rock from San Francisco Harbor. In 1872 and 1872, he led the team that examined the seawalls and breakwaters at Trinidad Harbor, Santa Cruz, and Estero Bay.

Dredging removes material and deepens channels but may have unexpected effects elsewhere on the coastline. Governments make efforts to prevent flooding of the land by the building of breakwaters, seawalls, dykes and levees and other sea defences. For instance, the Thames Barrier is designed to protect London from a storm surge, while the failure of the dykes and levees around New Orleans during Hurricane Katrina created a humanitarian crisis in the United States. Land reclamation in Hong Kong also permitted the construction of Hong Kong International Airport through the leveling and expansion of two smaller islands.

Those on the western boundary of the port are positioned in a roughly linear arrangement on the breakwaters (moles) that defend the western and northern sides of the harbour. The lighthouses at the "A" Head of the South Mole and "B" Head of the Detached Mole stand sentry over the south entrance to the port. Those at the "C" Head of the Detached Mole and "D" Head of the Western Arm of the North Mole guard the north entrance to the port. The lighthouse at the "E" Head (Elbow) of the North Mole also serves as a harbour control room.

Attempts to close the breaches already started in November 1944, but lack of building materials, and of heavy construction equipment, and the destroyed infrastructure, together with the extensive minefields, hampered these efforts. When in July 1945 the operations of closing the breaches started in earnest, the total width of the breaches had already increased to three kilometers. The great depth of the scoured-out breaches made simply moving earth into them infeasible. Therefore surplus caissons that had not been needed to form the Phoenix breakwaters of the Mulberry harbours were used to block the deepest part of the breaches, after which normal dike-building operations could proceed.

Apart from handling goods for Ghana, it is also a traffic junction, where goods are transhipped, and transit cargo destined for the landlocked countries to the north of Ghana. The port of Tema handles the majority of the nation's import and export cargo and most of the country's chief exports is shipped from Sekondi-Takoradi and Tema. The port of Tema has of breakwaters, 12 deepwater berths, an outsize oil tanker berth, a dockyard, warehouses, and transit sheds. The port has open and covered areas for the storage of cargo, including a 77,200-m² (7.72-hectare) paved area for the storage of containers, steel products and other conventional cargo.

The city's economy is based on rice growing, beef cattle and sheep raised for wool, in addition to being a transit point on BR-471, the main highway linking Brazil and Uruguay. Santa Vitória do Palmar is a large municipality, about long North-South. Its coast also includes the larger part of Cassino Beach, the world's longest uninterrupted stretch of sandy ocean shore, over from the stony breakwaters of Rio Grande in the north to the mouth of Chuí River in the south. Two small beach resort villages are located in the municipality: Praia do Hermenegildo and Barra do Chuí, which is Brazil's southernmost inhabited place.

The Sines Container Terminal, called Terminal XXI, started its operations in 2004 under a public service concession by the company PSA Sines (PSA, a global port operator, formerly the Port of Singapore Authority). Terminal XXI provides beds of 16 metres ZH, allowing the mooring of large container ships from intercontinental routes and of the ships with the respective connections by feeder. The open sea port is sheltered by two breakwaters – West Breakwater (2.000 m N-S orientation) and the East Breakwater (2.200 m NW-SE orientation). The Port of Sines and the Industrial and Logistics Zone offer road and rail connections directly linked to the terminals.

The western part of the port consists of a long sub- peninsula, whose most characteristic element is an English watchtower built at the beginning of the 19th century, located at its northeastern end. Close to the coast, there are two small rocky islands which act as breakwaters. Regarding the eastern side of the port, it presents similar characteristics to those of the western side, and where S’Almadrava is located, a house which was built in the 18th century as a shelter for fishermen. Moreover, an old quarry of limestone and a lime kiln are located to the south of the port, possibly belonging to the 18th or 19th century.

Open channel applications include bank stabilization, flow and grade control, scour protection for bridge piers, and biostabilization. The primary mechanism of protection employed is an increase in the relative roughness of the channel bank (as characterized by the Manning's Roughness Coefficient); the Manning's n is relatively high at 0.1. The advantage of A-Jacks over other hard armoring solutions is the comparatively large area available in the interstitial spaces for native vegetation to take root, ultimately helping to restore the stream bank to a more natural state while continuing to protect against erosion. In coastal applications A-Jacks are used as breakwaters, revetments, artificial reefs, and habitat development.

Her wreck became known as "Old Hole in the Wall". Despite her 1914 scuttling, the Royal Navy included Hood on its sale list in both 1916 and 1917. The ship's bell was later used as one of at least two bells on the battlecruiser . Before being installed on the battlecruiser, the bell was inscribed around the base with the words: “This bell was preserved from HMS Hood battleship 1891-1914 by the late Rear Admiral, The Honourable Sir Horace Hood KCB, DSO, MVO killed at Jutland on 31st May 1916.” The outline of the wreck of Hood can be seen between the breakwaters of Portland Harbour.

For the civilian works, DEME is teaming with British contractor Laing O'Rourke. With the formal delivery on 31 March 2010, DEME completed the widening and deepening works in the port of Durban, South Africa that had begun in mid-2007. The existing northern breakwater was demolished and rebuilt; the existing southern breakwater was strengthened; the port entrance channel was widened from 120m to 220m; and deepened from 12.8m to 19m in the outer channel and 17m in the inner port. A total of more than 10 million m3 of material was dredged, part of which was used for the foundation and reinforcement of the breakwaters.

At the outbreak of the Second World War, Gibson offered his services as an engineer to his country. For the duration of the war his family moved to a more rural location, and Gibson lent Stanwell Place to the United States Army High Command. It was used for two high level meetings of the Supreme Allied Command of General Dwight D. Eisenhower held in late June and mid-July 1944, with attendees including Henry Stimson, George Marshall, and Admiral Ernest King. After the agreement to proceed with a design for the Mulberry harbours for the 1944 Normandy landings, Gibson created the detailed design for the Phoenix breakwaters.

It also provides for the future possibility of mainline Asia–Europe vessels making a stop in southern India, which has been mooted as a distinct possibility by certain analysts. Kattupalli's North and South breakwaters, which together total 3.35 km, ensure a safe harbour and uninterrupted terminal operations. The yard has 3 rail-mounted quayside cranes (RMQCs) (arrived at the port in December 2011 from China), 15 rubber-tyred gantry cranes (RTGCs), two reach stackers and 420 reefer plug points. On 12 April 2012, the yard received Zhen Hua 20, a heavy lift vessel, with three more RMQCs to be installed at the second berth.

After the flood, the city directed its resources to building the breakwaters. A project was planned in 1905 to build the breakwater, but the city council only had $500 available to do the work, which was not nearly enough. They appealed to the county, but the county didn't have enough money either. Since New Mexico was still a territory at that time, there was a paucity of taxable property and no federal aid. When New Mexico became a state in 1912, the city formed a planning commission with the vision of a "city different" emphasizing its traditional architecture and preserving its historic meandering streets.

After completing the Liverpool defences in December 1914, 1/3rd (Works) Company was sent to Malta, where TF units were relieving the regular garrison for active service elsewhere. Then in 1915 the company was sent on again to join the Gallipoli Campaign. It served at Cape Helles until September, when it was withdrawn to the offshore base on the island of Imbros where it was engaged in erecting workshops and sinking ships for breakwaters.1/3rd Lancashire Company War Diary, 1915, The National Archives (TNA), Kew file WO 95/4356. After the Allied evacuation from Gallipoli the company went to Egypt, where it was designated the 3rd Lancashire Army Troops Company.

Folkestone-with the now closed down Rotunda amusement park on beach Folkestone is located where the southern edge of the North Downs, escarpment meets the sea. In contrast to the white cliffs at Dover further to the east, the cliffs at Folkestone are composed of Greensand and Gault Clay. A small stream, Pent Brook, cuts through the cliffs at this point, and provided the original haven for fishermen and cross-channel boats. The cliffs are constantly under attack from the sea: the original headlands, which once protected the port, ceased to do so, and artificial protection, in the form of breakwaters and piers have been necessary since the 17th century.

Deposition of sediment meant the entrance to the port continued to drift and in 1818 the original 1760 cut was re-excavated and groynes and breakwaters were built to protect it. In 1821 the cut was made a permanent opening by the building of walls while in 1860 the old channel east of Kingston was canalised to become a basin where water levels were controlled by locks. The estuary appears to have been stabilised from 1816, however, the mud and sand banks within the estuary have shifted. The western arm of the shingle bar has gained sufficient material for housing development to be permitted.

The thriving textile, food and tourist industries and its development into the most popular holiday destination in northern Portugal, led to a major growth between the 1930s and 1960s. On December 16, 1948, the Anteplano de Urbanização da Póvoa de Varzim (Urbanization Pre-plan) was approved by the national government. The Port of Póvoa de Varzim breakwaters started being built in 1939, a 200-year-old wish of the city, although the first works started in 1795. In the 1960s, the Palace of Justice was built using Soft Portuguese style, and Póvoa de Varzim was granted city status on June 16, 1973, by the decree 310/73.

The early white settlers cleared much of the island's land for farming. Lobsters were so plentiful that they were used as fertilizer for the fields. Early commerce on the island developed around fishing, farming, and the construction of "stone sloops," ships that carried quarried granite down the eastern seaboard for the building of breakwaters, lighthouses, and set navigational markers. By the late 19th century and throughout the early 20th century, tourists from Canada, Boston, and points south began to visit Maine in a phenomenon sometimes known as the "rusticators" movement, where residents of New England's industrial cities sought to get back to nature for a few days or weeks.

The pier is notable for being underpinned by three separate submerged buoyant concrete caissons, which are spanned by long steel girders supporting the building above. Designer Emil Praeger of the firm Madigan-Hyland had created similar structures as part of the American military effort in World War II, including temporary breakwaters that were used as part of the D-Day invasion. The caissons were constructed in 1951 and 1952 inside a diked and drained pond in Grassy Point near Haverstraw, New York, and after completion were floated down the Hudson to the site. The two largest (in terms of volume) concrete caissons are long, wide and high.

These began in the early Autumn of 2014 and continued until Easter 2015. These were "Listed Building Repairs" and included removal and replacement of the outer stone courses and part of the central Victorian concrete core. Replacement included the use of large quantities of modern marine concrete in the hope that it would stabilise and provide protection from further storm damage. In 2016 the National Trust reported that since 1945 it has spent more than £2 million repairing the breakwaters (piers)and over the last 20 years an average of £1500 per week has been spent as winter storms have become more frequent and violent.

This precipitation alleviated a flash drought from September. Farther north in Ontario, already-high water levels on Lake Erie were exacerbated by strong winds, sustained at 51 mph (82 km/h) and gusting to 65 mph (104 km/h) in Port Colborne. A water rise of at least 7.5 ft (2.3 m) was reported, causing the lake to overflow its banks and cause a number of road closures in Port Dover, Long Point, and Turkey Point. The nearby Niagara River also caused local inundation and road closures as waves up to 20 ft (6 m) crested over breakwaters across Fort Erie and Crystal Beach.

Remains of Mulberry harbour B at Arromanches- les-Bains (Gold) as seen in 1990 In response to the lessons learned at the disastrous Dieppe Raid, the Allies developed new technologies to help ensure the success of Overlord. To supplement the preliminary offshore bombardment and aerial assaults, some of the landing craft were equipped with artillery and anti-tank guns to provide close supporting fire. The Allies had decided not to immediately attack any of the heavily protected French ports and two artificial ports, called Mulberry harbours, were designed by COSSAC planners. Each assembly consisted of a floating outer breakwater, inner concrete caissons (called Phoenix breakwaters) and several floating piers.

The facility was completed the following year. On 2 April 2001 the museum was officially opened by Monique de Vries, Minister of Transport, in the presence of volunteers, sponsors and invited guests. The Phoenix caissons were designed by the British in the Second World War to form Phoenix breakwaters as part of the artificial Mulberry harbours that were assembled as part of the follow-up to the Normandy landings, but these four reinforced concrete caissons were not used in the war. Instead they were used to close the last gap in the dike at Ouwerkerk in November 1953; these are the caissons that house the museum.

Gibraltar Harbour (pictured on map), also referred to as the Port of Gibraltar, is on the west side of the British Overseas Territory of Gibraltar, at latitude 36º09'N, and longitude 5º20'W. In addition to the protection provided to the port by the Rock of Gibraltar on the east, there is a system of manmade defences on the west. These include a trio of breakwaters: the North Mole (formerly the Commercial Mole) including its Western Arm, the Detached Mole, and the South Mole. The South Mole includes an extension which was added later, and was formerly known as the New Mole and New Mole Extension.

Gibraltar Harbour (shown on map), also referred to as the Port of Gibraltar, is on the west side of Gibraltar, at latitude 36°09'N and longitude 05°20'W. In addition to the protection provided by the Rock, the harbour now has a system of man-made defences. These include three breakwaters: the North Mole (formerly the Commercial Mole) with its Western Arm, the Detached Mole (in the middle), and the South Mole. The mole was defended by the North Mole Elbow Battery, which operated until as late as the end of the Second World War, with another gun mounted at the end of the mole.

During the trial, an onshore gale produced heavy seas, but Robert's bombardons calmed the waves effectively. Assembling two Mulberry Harbours the day after the landings on 7 June 1944 was one of the most remarkable engineering feats in history. A total of 1,500,000 tons of harbour equipment had to be taken across the channel in an operation involving 150 Allied tugs, and by D-Day 'plus 12', most of Lochner's concrete breakwaters were in position. On 23 July, Churchill visited the harbours and on his return stated: "This miraculous port has played and will continue to play a most important part in the liberation of Europe".

Coode's proposal, that was adopted by the commissioners, was to form a harbour enclosing an area of 107 acres by means of two breakwaters, the Eastern Breakwater running north from Pulpit Rock and the northern one in a south easterly direction from Para [now Fairy] Creek. Some evidence remains today of the start made on the northern breakwater which was to run from Pulpit Rock. However, in the depressed times finance was not forthcoming and the work was abandoned. Early in 1893 a start was made to construct a breakwater running north from the Breakwater Lighthouse, but this was halted after only 240 feet had been built.

Sjúrður við kellingar was shown mercy and amnesty, but the story goes that he could not live with the crimes that he and the others had committed under their "little" rebellion and asked to be executed with the other Floksmenn. Because the harbour of Fugloy is not protected by breakwaters, it has stopped any form of economic growth since the early 20th century. The island's only income has been agriculture and some fishing, but also the famous catching of birds such as the puffin has been used on Fugloy to this day. The Faroese parliament has tried to work out plans for the future of the island, such as the island getting electricity in the 1960s.

Access to the two dry docks was by way of a tidal basin, tellingly known as the Mud Dock; there was a small shipbuilding slip to its north and an ordnance wharf to the south, with timber stores and a mast pond beyond. The constricted area of land available to the dockyard caused problems for its operation and development. Several hulks were positioned on the foreshore close to the dockyard, initially to serve as breakwaters, but soon they served to accommodate both personnel and dockyard activities. The space between the hulks (and, as they began to rot, the hulks themselves) were progressively infilled with soil, with new hulks then being added as part of the process.

Mr. Darlings duties under the direction of the government officer, included the designing and construction of breakwaters, entrance piers, channels and anchorage basins, plans for the establishment of harbor lines, inspection of bridge construction over navigable waters, location and marking of wrecks, reported shoals and other obstructions, making preliminary examinations for improvements, final surveys, and estimates of proposed improvements. In these he was of course associated with other assistant engineers draftsmen, inspectors etc. Special observations were made by Mr. Darling in 1902 of magnetic variations over that portion of Lake Superior west of Devils Island, including regions of local compass attraction, which had been reported and which endangered navigation by drawing vessels from their courses.

Having served in New York's militia before the Civil War, when hostilities commenced he was commissioned as a second lieutenant in the Union Army's 1st Artillery Regiment. He was later promoted to first lieutenant and brevet captain, and served as assistant adjutant general under General Banks and assistant inspector general under General Philip Sheridan. He remained in the Army after the war, and received brevets as major and lieutenant colonel for his part in defending the U.S. border during the French occupation of Mexico and participation in Custer's campaigns during the Indian Wars. After leaving the Army in 1871, Crosby worked as an engineer, and designed and oversaw construction of lighthouses, breakwaters, and other marine projects.

As it was not possible to adapt the kingpost bearing and full-circle slewing of the Port Alfred crane to this new load, the design reverted to the Manora type where the lower frame of the crane allowed blocks to pass beneath it on wagons. The jib was now separate from the lower frame though, supported on two carriages which could move sideways, thus allowing the jib to slew over a small angle. For building linear breakwaters, this small slew angle was enough. Although the mechanical design of the jib was as a kingpost truss, this kingpost was now part of the jib and rotated with it, rather than fixed to the frame beneath it.

The mild-slope equation models the propagation and transformation of water waves, as they travel through waters of varying depth and interact with lateral boundaries such as cliffs, beaches, seawalls and breakwaters. As a result, it describes the variations in wave amplitude, or equivalently wave height. From the wave amplitude, the amplitude of the flow velocity oscillations underneath the water surface can also be computed. These quantities—wave amplitude and flow-velocity amplitude—may subsequently be used to determine the wave effects on coastal and offshore structures, ships and other floating objects, sediment transport and resulting bathymetric changes of the sea bed and coastline, mean flow fields and mass transfer of dissolved and floating materials.

The museum board and staff also work to help save other lighthouses in Florida and across the nation, coordinating efforts with several federal agencies and volunteer groups such as the Florida Lighthouse Association. The Lighthouse employs close to 50 individuals, and is visited annually by over 200,000 people including 54,000 school-aged children. The museum maintains an active archaeological program (Lighthouse Archaeological Maritime Program, or LAMP) that researches maritime archaeological sites around St. Augustine and the First Coast region. Staff archaeologists have discovered a number of historic shipwrecks and investigated many others, along with other maritime sites such as breakwaters, plantation wharf remains, and the nearby remains of St. Augustine's original lighthouse.

Port Kembla was selected, by the New South Wales Government at the end of 1898 as main port for area and in 1901 construction commenced on two breakwaters to protect two existing coal jetties at the site and to enclose and area of seabed that became the Outer Harbour. In 1908, it first became the site of heavy industry when the Electrolytic Refining and Smelting Company's plant was opened. The first association of Charles Hoskins with Port Kembla was in 1911, when there was talk of an ironworks at Port Kembla to process Tasmanian iron ore. In 1912, BHP planned to set up a large steelworks at Newcastle to exploit its vast South Australian iron ore deposits.

However, due to bickering no plans were proceeded with and despite campaigning by the Island's press progress in any direction was slow. Much of this was to do with rival proposals for the construction of breakwaters at Peel and Ramsey both of which, as was the case with Douglas, would ultimately rely on approval and funding from the Admiralty. Plans for the Douglas Breakwater were amended by Capt. Vetch but again these were subject to differing opinions and despite the requisite monies being available from 1851 and a further report submitted in 1859, it was not until 1861 that a further set of plans submitted by James Abernethy were approved by the Lords Commissioners of the Admiralty.

PNPS operated a single reactor unit with a boiling water reactor and a steam turbine generator. The cooling and service water systems operated as a once- through cooling system, with Cape Cod Bay being the water source. The water was circulated in the plant's heat exchanger in the same manner as any fossil- fuel powered power plant, using the seawater to remove heat from primary coolant away from sources of radioactive contamination. Approximately 480 million gallons of seawater were withdrawn daily from the bay through an intake embayment formed by two breakwaters, and then re-deposited into the bay causing a change in temperature at peak times (ΔT) of 3 °C (5.4 °F).

They put a bid in for the Easter Greenock estate for a harbour, but were outbid and the lands became the Barony of Cartsburn. They then negotiated with Sir Patrick Maxwell of Newark Estate, and in 1668 he agreed to lease the City of Glasgow of land to the west of the castle, for payment of 1,300 merks and an annual feu duty of four merks. Construction of piers and breakwaters enclosing the harbour began promptly, and Newport Glasgow was constituted as a free port. Trade prospered quickly, and by 1710 Newport Glasgow had the principal Clyde custom house, initially in Customhouse Lane, then after 1754 in a new building constructed on the west quay of the harbour.

The new port was opened to traffic in 1907 and in 1909 its population was largely composed of labourers. The harbour was formed by the construction of two breakwaters, the western and the eastern long, which curve toward each other at their outer extremities and leave an entrance wide. The enclosed space is divided into an outer and inner harbour by a double line of quays wide enough to carry six great warehouses with electric cranes on both sides and a number of railway tracks. Connected with the new port works was one of the then-largest dry docks in the world long and wide, with a depth of on its sill at low water.

Galaxy was acquired for the express purpose of research in underwater sound. Based at East Boston throughout her entire career, as a unit of the 1st Naval District, she completed a variety of assignments for the Underwater Sound Laboratory, Fort Trumbull, New London, Connecticut; experimental underwater sound work for the Bureau of Ships and the Harvard Underwater Sound Laboratory. These operations were carried out at Boston and off New London; and for a brief time off the Delaware breakwaters and in the Chesapeake Bay. She was decommissioned and was placed "in service" on 2 August 1945, to continue her experimental assignments until placed out of service at Boston on 25 March 1946.

In October 2011, plans for Fishguard & Goodwick Marina were revealed in the Western Telegraph. The developers Conygar who hope to invest £100 million into the project have submitted plans to Pembrokeshire County Council for a 450 berth marina, 253 new residential flats and a 19-acre platform for the potential expansion of the existing Stena Line port. The scheme would also create a publicly accessible promenade and waterfront, and visitor parking as well as workshops, stores and ancillary facilities. If approved most of the proposed new developments will be sited by reclaiming land from the sea bed within the two existing breakwaters mainly near the current 'Ocean Lab' and alongside the existing ferry terminal access roads.

The Long Point community continued to grow, and by 1846, the Town of Provincetown voted to build a schoolhouse on Long Point. By then, the village was home to 38 fishing families, with nearly 200 adults and 60 children. In describing the experience of living on Long Point in the early 1800s, one author wrote: By 1836, Long Point had 34 buildings, plus 9 windmills for several saltworks. Stereoscopic view of a 19th-Century windmill, just one of the dozens that once dotted Provincetown's shoreline The village had its own post office, a bakery, boat landings for 20 cod-fishing vessels, breakwaters, and several saltworks with nine windmills that were used to pump seawater into about of drying pans.

This is often required where the flow of new sediment caused by the longshore current has been disrupted by construction of harbors, breakwaters, causeways or boat ramps, creating new current flows that scour the sand from behind these structures and deprive the beach of restorative sediments. If the causes of the erosion are not addressed, beach nourishment can become a necessary and permanent feature of beach maintenance. During beach nourishment activities, care must be taken to place new sediments so that the new sediments compact and stabilize before aggressive wave or wind action can erode them. Material that is concentrated too far down the beach may form a temporary groyne that will encourage scouring behind it.

The clubhouse in Osprey Quay Portland Harbour and Weymouth Bay are the main areas used for sailing. The harbour covers an area of , and is ideal for sailing as it is exposed to reliable winds from most directions, but is sheltered from large waves and currents by Chesil Beach and the breakwaters. The clubhouse houses facilities on two floors, including a gymnasium, seven lecture and meeting rooms for 260 people, an event hall with kitchens and a bar, VIP meeting rooms and offices, a lounge bar and cafeteria seating 350 people, and two balconies. The outside of the academy complex has a slipway and two deep water slipways, 30 pontoons with disabled access, cranage and boat hoists, boat storage and parking areas.

The original villageUnfortunately, Parton Bay is not as well sheltered as Whitehaven, and within about 15 years, Lamplugh was unable to afford maintenance costs (possibly a contributory factor to the closure of the glassworks and salt-pan about this time). The manor of Moresby was bought in 1722 by one Thomas Brougham, who was able to sideline Lamplugh and develop the port himself, but ironically, in 1738, he sold his rights to the Lowther family. Surprisingly, rather than shut down the port which rivalled Whitehaven, they used it themselves for some of their coal shipments, and Parton prospered for decades. New industries developed, most notably a brewery, but everything was nearly wrecked in 1795, when a storm destroyed the harbour breakwaters.

In 1892 the lighthouse became the first light of the Lapa-Regufe alignment of Póvoa Bay slope. By getting the alignment between the two points of light of Farol da Lapa and Farol de Regufe, known as enfiamento, the fishermen knew that the boat was in the strait corridor between underwater rocks and it was safe to cross the sandbank where numerous fishermen lost their lives in the course of several generations. The lighthouse was activated when the crossing of the sandbank became dangerous due to sea levels or storms. In the 1960s it was deactivated, probably due to the construction of the new breakwaters as the alignment became inappropriate It was recovered and reactivated on August 2016, along with the church.

By this time, the perimeter ran along a series of canals about from the coast, in marshy country not suitable for tanks. With the docks in the harbour rendered unusable by German air attacks, senior naval officer Captain (later Admiral) William Tennant initially ordered men to be evacuated from the beaches. When this proved too slow, he re-routed the evacuees to two long stone and concrete breakwaters, called the east and west moles, as well as the beaches. The moles were not designed to dock ships, but despite this, the majority of troops rescued from Dunkirk were taken off this way. Almost 200,000 troops embarked on ships from the east mole (which stretched nearly a mile out to sea) over the next week.

A2 motorway, also known as "Sun's Highway" The opening, in 1895, of the railway to Bucharest, which crosses the Danube River at the bridge at Cernavodă, brought Constanța considerable transit trade in grain and petroleum, which are largely exported; coal and coke head the list of imports, followed by machinery, iron goods, and cotton and woollen fabrics. The A2 motorway provides a rapid road link between Constanța and Bucharest, while the A4 motorway acts as the city's outer traffic ring, diverting heavy traffic to and from the Port of Constanța and to Mangalia. The Port of Constanța includes the North Port and the South Port, and is the fourth largest in Europe. It is protected by breakwaters, with a lighthouse at the entrance.

Jellett was commissioned as a Temporary Captain in the Royal Navy Volunteer Reserve in 1944 and appointed superintending civil engineer of Mulberry Harbour B, a temporary concrete harbour built at Arromanches, France to support the Normandy Landings.Kings College archives He was responsible for siting the blockships and Phoenix breakwaters that protected the harbour. Mulberry B was in use for five months after the invasion and landed two million men, half a million vehicles and four million tons of supplies for the Liberation of Europe. Mulberry A, under control of American forces and more exposed to the weather, was wrecked by a storm in late June and abandoned, leaving Jellett's harbour as the main landing point for supplies to the allied forces in France.

In addition, the Port of Mundra's basin on the south side of Navinal Island will be developed in two phases to enhance the chorkarmas. Scheduled to be completed in 2010, Phase IIA will include breakwaters, dredging, reclamation as well as construction of a basin container terminal, two roll-on/roll-off service berths, a craft berth, and support and back-up facilities. The railway line will be expanded, and a new dedicated berth will be added for liquefied natural gas. The Port of Mundra is also upgrading its road network, adding two lanes to the existing two-lane road. The current capacity of port to handle 2.5 m TEU's is to be expanded to 5 m TEU by 2015, making it India's second largest container port.

Plaque commemorating the founders In the late 1940s, Charley Atkins, a Recreation and Parks employee, and some rail enthusiasts came up with the plan that a full-size steam locomotive would be an attractive addition to the miniature railroad ride at Griffith Park. The City of Los Angeles Harbor Department had two small locomotives destined for scrap that seemed to be suitable for this purpose. These locomotives had worked at a quarry on Santa Catalina Island, California, carrying stone to be used building breakwaters for the Port of Los Angeles.Best, p.3 With the support of former Recreation and Parks Department General Manager George Hjelte and Superintendent of Recreation William Frederickson, Atkins initiated contacts with major railroads in California to ask what equipment they could donate.

Peterhead Bay is a large remote industrial tidal 120° facing coastal embayment, located next to the planned community, commercial fishing and ship building town of Peterhead in the Presbytery of Deer, Buchan, Aberdeenshire and is in the most easternmost point in mainland Scotland. The bay lies to the south of the town, forming a large natural harbour. It was enclosed by breakwaters, to turn the natural harbour into a marina and port, that is now owned by the Port of Peterhead. It was here, on 25 December 1715, that the old pretender, James Francis Edward Stuart, landed and resided at a house at the south end of Longate, owned by Mr James, and being visited by his friends, including George Keith and Earl Marischal.

In 2006, after another court case (Supreme Court Queensland), two short rock breakwaters were built, extending 100m into the Hinchinbrook Channel to the boundary of the Great Barrier Reef World Heritage Area. In 1977 the Queensland Harbours and Marine Department had published a report (Boat Harbour Feasibility Study) describing the site as unsuitable for a "boat harbour" (an older concept than "marina", in the days of small sailing craft) because it had "no naturally deep water", was "in a catchment", was subject to (cyclonic) "storm surge" and was subject to "severe siltation".documents held by Alliance to Save Hinchinbrook Inc. and Queensland Government Severe siltation means that the seabottom sediments (in this case having a high acid marine mud component) are always on the move.

The port of Haydarpaşa seen from the Fourth Courtyard of the Topkapı Palace The Port has 21 berths alongside two large piers. The berths are specialized for particular port industries, with one for motor boat servicing at 150 m in length, two for dry bulk cargo (430 m long), 8 large-size berths for general cargo (between 160 and 334 m), 3 mid- size general cargo berths (between 50 and 97 m), two ro-ro terminals (141 and 164 m) and, finally, 5 container terminals (between 295 and 350 m). The depth of water at the quays varies between 5 and 10 m. The vessels in the port are protected by two breakwaters from all kinds of effects caused by the weather and sea.

In 1842 Vetch designed a system of sewerage for the borough of Leeds, which was carried out. In 1843 he was associated with Sir Henry Thomas de la Beche in designs for the drainage of Windsor, and in 1844 designed drainage for Windsor Castle and parks and for the purification of the Frogmore lakes; these works were completed in 1847. After the Duchy of Cornwall Act 1844, Vetch was appointed one of the three commissioners to carry changes in tenancies, John Douglas Cook acting as secretary. In 1844, 1845, and 1846 Vetch was examined by the Commissioners Upon the Subject of Harbours of Refuges, and at their request wrote a report on wrought iron frameworks in the construction of piers and breakwaters.

In a 2020 interview, the former master of Rhosus stated that there was a small hole in the hull and, with no crew on board to periodically pump the sea water out, the vessel sank "two or three years ago" after the cargo had been unloaded. Euronews reported that the records of Lloyd's List showed that Rhosus was seized in February 2014, and that it sank without a crew in the breakwaters of the Port of Beirut in February 2018. The New York Times confirmed via multispectral satellite imagery that the ship sank between and aside a Beirut pier. Since 2018, Rhosuss flag has been reported as "unknown" in official databases and the vessel's status was updated to "total loss" in August 2020.

In particular, Morarity is noted for his involvement in the construction of the Dyke a river training wall on the western bank of the Hunter river at Newcastle which was developed into a coal loading facility and basin equipped with hydraulic cranes for loading coal and an associated rail link. In 1862 Moriarty was made commissioner for roads and engineer-in-chief. He was a Sydney Water Supply Commissioner in 1868, president of the Hunter River Floods Commission in 1869-70, and also responsible for water supply schemes for Albury, Bathurst, Hunter Valley towns, Wagga Wagga and Wollongong. Moriarty was made responsible for the Clarence River Entrance Works between 1862 and 1889, where he proposed short breakwaters and rock training walls.

Colonies of Zoobotryon verticillatum are found in shallow water in the tropical and subtropical western Atlantic and the Caribbean Sea and many other parts of the world. It is tolerant of a range of water conditions but grows best at salinities of at least 30ppt and water temperatures over . It is a common species in the Indian River Lagoon where it grows vigorously from April to September but dies back during winter. Zoobotryon verticillatum is a fouling organism and its typical habitat is growing on the blades of seagrasses, the thallus of large seaweeds, the roots of mangroves, rocky reefs, the shells of bivalve molluscs, piers, breakwaters and other man-made structures, the hulls of boats, floating masses of seaweed and other floating debris.

Since the condition of the steamer's hull was not fully known it was decided first to remove as much cargo as possible before further evaluation could be performed. The work on discharging cargo started right away and continued for several days while the weather was still good, with cargo beingtransferred to lighters and carried to port. On January 2, 1904 a storm swept through the area and possibly damaged Kiowa as a lot of wreckage came ashore afterwards, including barrels of turpentine, cases of oranges, bales of lumber and cotton. Large quantities of timber came ashore in Nantasket destroying several wooden breakwaters in the process, while many cases of oranges and barrels of oil and turpentine were washed on shore and picked up by local residents.

Harbor Jurisdiction, Section 10-40-010 Definition In a more narrow sense, the Chicago Harbor is that artificial harbor on Lake Michigan located at the mouth of the Chicago River bounded by outer breakwaters to the north and east, Northerly Island to the south, and the Chicago shoreline to the west. The main entrance to this harbor is marked by the Chicago Harbor Lighthouse. The Jardine Water Purification Plant, Navy Pier, the Chicago Harbor Lock, Coast Guard Station Chicago, the municipal harbors - Dusable Harbor and Monroe Harbor, and the yacht clubs - Chicago Yacht Club and Columbia Yacht Club are all located here. The Port of Chicago is located within the greater Chicago Harbor in and around Calumet Harbor, the Calumet River, and Lake Calumet.

The original configuration of the breakwaters was graced by a tower on the south side of the lake entrance in 1874, shortly after the canal was constructed. Requests for funds to construct a corresponding light on the inner end of the breakwater were made beginning in 1880, but an appropriation was not made until 1889. Construction proceeded quickly on an open wooden pyramidal tower surmounted by a watch room and iron lantern, the latter housing a fourth-order Fresnel lens which rotated to provide a six- second flash; the light was first displayed in September 1 of that year. On the 17th, the India struck the end of the breakwater, but the damage to the light was minor and quickly repaired.

Biography of E W Cooke (National Maritime Museum, Greenwich) In 1858, he was elected into the National Academy of Design as an Honorary Academician. Cooke was "particularly attracted by the Isle of Wight, and on his formative visit of 1835 he made a thorough study of its fishing boats and lobster pots; above all he delighted in the beaches strewn with rocks of various kinds, fishing tackle, breakwaters and small timber-propped jetties." He also had serious natural history and geological interests, being a Fellow of the Linnean Society, Fellow of the Geological Society and Fellow of the Zoological Society, and of the Society of Antiquaries. In the 1840s he helped his friend, the horticulturist, James Bateman fit out and design the gardens at Biddulph Grange in Staffordshire, in particular the orchids and rhododendrons.

By the end of 1925, they had built a small seven-metre-deep harbour, the south pier, part of the north pier, a railway, and had ordered the trans-shipment equipment. The works were going more slowly than expected, however. They accelerated only after May 1926, because of an increase in Polish exports by sea, economic prosperity, the outbreak of the German–Polish trade war which reverted most Polish international trade to sea routes, and thanks to the personal engagement of Eugeniusz Kwiatkowski, Polish Minister of Industry and Trade (also responsible for the construction of Centralny Okręg Przemysłowy). By the end of 1930 docks, piers, breakwaters, and many auxiliary and industrial installations were constructed (such as depots, trans-shipment equipment, and a rice processing factory) or started (such as a large cold store).

In 1898, Port Kembla was selected for further development as the main port for the Illawarra region. Between 1901 and 1937, first an eastern breakwater and then a northern breakwater was constructed, resulting in a large protected and safe anchorage now known as the 'Outer Harbour'. The eastern breakwater extended from the rocky headland and the northern breakwater extended from the beach at a point just south of where Tom Thumb Lagoon and Allen's Creek emptied into the sea. An advantage of Port Kembla over other potential sites for a port—Wollongong, Bellambi, and Lake Illawarra—was that there was suitable stone for the breakwaters nearby and that the first part of the eastern breakwater could be placed on an existing natural reef extending seaward from the rocky headland.

The model is approximately 320 feet long in the north-south direction and about 400 feet long in the east-west direction. It is constructed out of 286 five-ton concrete slabs joined together like a jigsaw puzzle. Features that affect the water flow of the San Francisco Bay and Sacramento-San Joaquin Delta are reproduced, including ship channels, rivers, creeks, sloughs, the canals in the Delta, fills, major wharfs, piers, slips, dikes, bridges, and breakwaters. The limits of the model encompass the Pacific Ocean extending 17 miles beyond the Golden Gate, San Francisco Bay, San Pablo Bay, Suisun Bay and all of the Sacramento-San Joaquin River Delta to Verona, 17 miles north of Sacramento on the north, and to Vernalis, 32 miles south of Stockton on the San Joaquin River on the south.

Authorized construction of the breakwaters to a greater height at the project at King Harbor, Redondo Beach, California, if recommended in a report of the Chief of Engineers. Modified the navigation project for Los Angeles and Long Beach Harbors, San Pedro Bay, California, to provide that if non-Federal interests carry out any work associated with such project which is later recommended by the Chief of Engineers and approved by the Secretary, the Secretary may reimburse such non-Federal interests an amount equal to the Federal share of the costs, without interest. Modified the navigation project at Annapolis Harbor, Maryland, to realign the channel in such project to promote more efficient mooring operations. Authorized paying for the remaining cost for the navigation project for Deal Island, Maryland (Lower Thorofare).

The Port of Mogadishu was created as a modern port (called in Italian Porto di Mogadiscio) with magazines and docks in the late 1920s by the Italian government of Italian Somalia. In 1930 a protective dike with breakwaters was made in front of the enlarged port,Map of the Mogadiscio port which was connected to the Somalia interior by a railway and even by a new "imperial road" (from Mogasdishu to Addis Abeba).Alberto Arecchi: Mogadiscio ed urbanesimo (in Italian) In 1934, the port of Italian Mogadiscio had exports of 43.467 tons of agricultural products (mainly bananas) to Italy and Europe. For this commercial transport were used the service of special container-ships called "RAMB" (that were built with the possibility to be converted to be an auxiliary cruiser).

Aerial view of the community of Silver Islet Silver Islet, circa 1911 Wire Silver from the Silver Islet Mine, on display at the Canadian Museum of Nature Silver Islet refers to both a small rocky island and a small community located at the tip of the Sibley Peninsula in northwestern Ontario, Canada. A rich vein of pure silver was discovered on this small island in 1868 by the Montreal Mining Company. At that time, the island was approximately [50 m²] in size and only 2.5 metres above the waters of Lake Superior. In 1870, the site was developed by Alexander H. Sibley's Silver Islet Mining Company which built wooden breakwaters around the island to hold back the lake's waves and increased the island's area substantially with crushed rock.

The proposed harbours called for many huge caissons of various sorts to build breakwaters and piers and connecting structures to provide the roadways. The caissons were built at a number of locations, mainly existing ship building facilities or large beaches, like Conwy Morfa, around the British coast. The works were let out to commercial construction firms including Wates Construction Balfour Beatty, Henry Boot, Bovis & Co, Cochrane & Sons, Costain, Cubitts, French, Holloway Brothers, John Laing & Son, Peter Lind & Company, Sir Robert McAlpine, Melville Dundas & Whitson, Mowlem, Nuttall, Parkinson, Halcrow Group, Pauling & Co. and Taylor Woodrow. On completion they were towed across the English Channel by tugs to the Normandy coast at only , assembled, operated and maintained by the Corps of Royal Engineers, under the guidance of Reginald D. Gwyther, who was appointed CBE for his efforts.

The Main Harbour covers the sweep from the Northern and Eastern breakwaters which mark a broadly North north east direction road past the harbour entrance and including all of the eastern part of the Harbour including St. Michael's Pier and Carlisle Pier and the five ship berths. Since 3 October 2018 the management and operation of the harbour has transferred to Dún Laoghaire–Rathdown County Council from the Dún Laoghaire Harbour Company. Almost 200 years of a Holyhead to Dún Laoghaire passenger ferry service ended in 2014 when Stena consolidated all its services on Dublin Port. The port does accommodate passenger cruise ships with seven visits scheduled for 2019 though two are too large for the harbour and are required to moor outside and be serviced by tender.

Cape Hatteras Light, USCG Archive photo Ever since the completion of the new tower in 1870, there had begun a very gradual encroachment of the sea upon the beach. This did not become serious, however, until 1919, when the high water line had advanced to about 120 ft (36.5) from the base of the tower. Since that time the surf gnawed steadily toward the base of the tower until 1935, when the site was finally reached by the surf. Several attempts were made to arrest this erosion, but dikes and breakwaters had been of no avail. In 1935, therefore, the tower light was replaced by an Aerobeacon atop a four-legged steel skeleton tower, placed farther back from the sea on a sand dune above the sea, visible for .

The government of China in August 2015 announced that concessionary loans for several projects in Gwadar totalling $757 million would be converted 0% interest loans. The projects which are now to financed by the 0% interest loans include: the construction of the $140 million East Bay Expressway project, installation of breakwaters in Gwadar which will cost $130 million, a $360 million coal power plant in Gwadar, a $27 million project to dredge berths in Gwadar harbour, and a $100 million 300-bed hospital in Gwadar. Thus, Pakistan only has to repay the principal on these loans. In September 2015, the government of China also announced that the $230 million Gwadar International Airport project would no longer be financed by loans, but would instead be constructed by grants which the government of Pakistan will not be required to repay.

In an interview in 1906, the General Manager of the Barry Railway said, > A passenger pontoon was constructed within the breakwaters, at which > passenger steamers land or take in passengers. The pontoon is served by > railway lines made from Barry through Barry Island, and it is now possible > for passengers from Cardiff, and the districts containing the teeming > population of South Wales, to travel by train to the pontoon, and embark for > the various watering-places and towns in the Bristol Channel.G A Sekon, > Illustrated Interview with Mr Edward Lake, General Manager of the Barry > Railway, in the Railway Magazine, October 1906 The Barry Island branch was extended to Barry Pier. The extension was authorised in 1896, and it opened on 27 June 1899. The line descended to Barry Pier through a tunnel at 1 in 80.

Between 1853 and 1855 he held the position of engineer and surveyor for the Steam Navigation Board and from 1855 to 1858 was engineer on the Hunter River improvements. He was then appointed Engineer-in-Chief for Harbours and River Navigation with the NSW Department of Works from 1858 to 1859. While in the military, in the 1850s (and with approval), he undertook external commissions for the Penrith Nepean Bridge Co. and the first Pyrmont Bridge in 1866. In 1855 Morarity was Engineer Surveyor for the Hunter river improvements and in that capacity made soundings and mapped the Hunter River at the Port of Newcastle which were developed into a plan to improve the entrance to the sea by constructing extended breakwaters and river control walls as well as develop the port faculties to improve the export of coal (Stewart 1983).

The government of China in August 2015 announced that the previously announced concessionary loans for several projects in Gwadar totalling $757 million would be converted 0% interest loans for which Pakistan will only be required to repay the principal value. The projects which are now to financed by the 0% interest loans include: the construction of the $140 million East Bay Expressway project, installation of breakwaters in Gwadar which will cost $130 million, a $360 million coal power plant in Gwadar, a $27 million project to dredge berths in Gwadar harbour, and a $100 million 300-bed hospital in Gwadar. In September 2015, the government of China also announced that the $230 million Gwadar International Airport project would no longer be financed by loans, but would instead be constructed by grants which the government of Pakistan will not be required to repay.

Some of the ship's more colorful owners have been Adolph Dick of the Dick sugar and banking family of New York; Hans-Wilhelm Röhl, co- owner of the Rohl-Connolly Co. (builder of the Port of Los Angeles breakwaters) and investigated in 1942 for pro-Nazi sympathies; aviation pioneer Thomas F. Hamilton; Crane Co. heir Cornelius Crane; renowned Honolulu- based skipper Omer Darr; Stimson Lumber Company scion Harold Miller; Dutch financier (and kundalini yoga teacher) Pieter Schoonheim Samara; and Calisto Tanzi, ex-chairman of the Parmalat group. In January 2006 she was sold to Italian fashion magnate Diego Della Valle (Tod's et al.). She was built with a 200-hp American Winton marine diesel engine, which was replaced by a 400-hp English Mirrlees in the 1950s. From the mid-1990s she has had a 700-hp German MTU.

In 1828 he submitted to the Prince Regent "A Plan of Internal Defence", and in November 1829 he sent to the Admiralty some remarks on the best mode of preventing "pestilential fevers", and offered his services to carry them out at Gibraltar. On 23 November 1831, Tayler sent to the Marquis of Lansdowne, then the Lord President of the Council, a plan for a Registry of Seamen, which would do away with the need for impressment. In 1838 he took out a patent on a new form of breakwater, and in 1840 another for improvements to steam vessels, and in 1843, in partnership with the civil engineer William Henry Smith, registered a patent for improvements in breakwaters, beacons, and sound alarms. He also invented a floating breakwater, and published a book On Naval Tactics and Gunnery.

The loss of velma areas in the Lagoon of Venice has been occurring for more than two centuries. From the early 19th century the combined saltmarsh area had decreased form 155 km2 to 40 km2.Mosevenezia, ecosystem, the Venice Lagoon This has also involved a loss of velma areas because many of them surround the saltmarshes. Velma areas are often under bathymetric (depth) pressure, which makes them less likely to emerge at low tides, leading to loss of stability and potential loss of their ecological function. 2011 Plan -Mitigation measures This has been caused by infrastructural works carried out in the last two centuries. In the 19th century breakwaters were built at the lagoon inlets to stabilise their shape and orientation and to intensify the inflow of sea current in order to create conditions for deepening them and the channels which start from them.

The Stone Fleet consisted of a fleet of aging ships (mostly whaleships) purchased in New Bedford and other New England ports, loaded with stone, and sailed south during the American Civil War by the Union Navy for use as blockships. They were to be deliberately sunk at the entrance of Charleston Harbor, South Carolina in the hope of obstructing blockade runners, then supplying Confederate interests. Although some sank along the way and others were sunk near Tybee Island, Georgia, to serve as breakwaters, wharves for the landing of Union troops, the majority were divided into two lesser fleets. One fleet was sunk to block the south channel off Morris Island, and the other to block the north channel near Rattlesnake Shoals off the present day Isle of Palms in what proved to be failed efforts to block access the main shipping channels into Charleston Harbor.

The port initially remained underutilized after construction for a variety of reasons, including lack of investment, security concerns, and the Government of Pakistan's failure to transfer land as promised to the port operator, Port of Singapore Authority. In April 2015, Pakistan and China announced their intention to develop the $46 billion China–Pakistan Economic Corridor (CPEC), which in turn forms part of China's ambitious One Belt, One Road. Gwadar features heavily in CPEC, and is also envisaged to be the link between the One Belt, One Road and Maritime Silk Road project. $1.153 billion worth of infrastructure projects will be invested into the city as part of CPEC,See list of projects: List of projects $230million for Gwadar Airport, $114m desalination plant, $35m for special economic zone infrastructure, $360m for coal plant, $140m for Eastbay Expressway, $100m for hospital, $130m for breakwaters, $27m for dredging.

A breakwater in the National Harbor of Refuge At 5 am on 5 February, Ice Boat No. 3, under the command of Captain W. F. P. Jacobs, arrived at the Delaware Breakwater "under orders to convey a fleet of ice- bound steamers, tugs, barges and schooners up to Philadelphia." In the National Harbor of Refuge between the two breakwaters, No. 3s paddlewheels became jammed by ice, and unable to maneouver, the vessel was dragged by the ice floes over a recently sunken barge, the Santiago, one of whose broken masts pierced the ice boat's hull below the waterline. Within minutes, water had extinguished No. 3s furnaces and the order was given to abandon ship. Unable to launch a lifeboat because of the surrounding ice, the crew were forced to leap for safety onto the ice floes, the ice boat sinking shortly thereafter, at about 6 am.

The Port's hinterland comprises southern parts of State of Tamil Nadu, Kerala and also some regions in the State of Karnataka. The facility available at the Port has propelled industrial growth in the region and is also emerging as power Hub of South India. In order to augment the increased demand of the EXIM trade, the Port is increasing the capacity to 85 million tonnes per annum by 2015-16 by commissioning new 5 berths under PPP mode and upgrading the existing facilities. During Budget speech in Feb 2013, the Hon’ble Union Finance Minister had also announced the Development of Outer Harbour project in V. O. Chidambaranar Port Trust for Rs.7500Crores As the capacity augmentation in the present harbor has reached the saturation level and to meet the future demands, the Port has proposed to develop an Outer Harbour by extending the present breakwaters.

Tredgold gave an influential definition of civil engineering, on which the charter of the Institution of Civil Engineers based itself in 1828: > A Society for the general advancement of Mechanical Science, and more > particularly for promoting the acquisition of that species of knowledge > which constitutes the profession of a Civil Engineer; being the art of > directing the great sources of power in Nature for the use and convenience > of man, as the means of production and of traffic in states, both for > external and internal trade, as applied in the construction of roads, > bridges, aqueducts, canals, river navigation, and docks, for internal > intercourse and exchange; and in the construction of ports harbours, moles, > breakwaters, and lighthouses, and in the art of navigation by artificial > power, for the purposes of commerce; and in the construction and adaptation > of machinery, and in the drainage of cities and towns.

According to theorists and scientists at the Seasteading Institute who have begun conducting research into aquatic environments as liveable spaces, many of the technologies supporting ocean colonization are set to mainly impacted by rogue waves and storms. However, other aquatic natural disasters such as Tsunamis, Friedman says would have little impact on the structures yet only raise water levels . Research in the 1990s emerged regarding the hydro-elasticity of rigid structures at the face of relentless and on-going wave movement to which lead to modern scientists such as Suzuki (2006), voicing their concern of the potentially poor integrity of aquatic structures impacting by constant motion and vibration . Breakwaters used to minimize wave destruction Further modern research and design has also been situated around testing the computation fluid dynamics of resistance against vortex formations of water , such as cyclones that form and therefore threaten ocean environments.

The dock's entrance was to have two locks, one large and one small, Rendel also proposed a canal connecting the old and new docks, both for ships and to supply the new docks with fresh water. Part of the basis of the design was to expose the dock entrance to the flow of tides for the greatest amount of time to increase scouring of the entrance, additionally Rendel supposed that the encroachment of the dock onto the Humber might constrict the flow of water in the vicinity of the "Inner Roads" to increase the flow, and thence scouring, so as to increase the depth of the navigable channel. Rendel also suggested reclaiming and extending eastwards the shallows at the Burcom Bank shoal north-west of Grimsby to further funnel the tidal flows. Total cost of the works was estimated at £500,000, of which £300,000 for the dock works, and up to £200,000 for the breakwaters if carried out.

A third box terminal has been approved by the Cabinet Committee on Infrastructure. This will require investment of US$800 million and will be offered as a build-operate-transfer project, as part of a 30-year concession. Construction will take seven years to complete and the deep-water container terminal will have a capacity of 4 million TEU. The mega container terminal project, expected to be the single largest terminal ever built in India, is to be developed north of existing Bharathi Dock with two new breakwaters (total length of ), continuous quay length of with alongside depth (ultimate) and a basin area of 300 hectares and back up area of 100 hectares. The gigantic proportions will feature 2 km quay length in a straight line at the new outer harbour, with a 2.75 km extension of the existing outer arm breakwater and a new northern breakwater of 1.73 km emanating from the eastern breakwater of the fishing harbour.

Hurricane Liza on September 2 during rapid weakening Despite never making landfall, the United States Weather Bureau warned that Liza could cause damage in California due to to swells it generated merging with high tide, creating to breaker waves which they reported could sweep over jetties and breakwaters as well as cause riptides on beaches. Officials at Long Beach were keeping an eye on breakwater activity and Laguna Beach lifeguards were prepared in case the swells reported there grew. At Newport Beach, the Corps of Engineers were brought in to create a buffer with sand and rock to protect homes between 41st Street and 46th Street, and concern in West Newport Beach was that the hurricane would cause more damage to oceanfront homes that were weakened by swirling seas the previous week. The waves were expected to be the only cause of damage from the hurricane, which forecaster Emii Kurtz remarked was "much too far away" to affect atmospheric weather conditions.

"The National Trust is already preparing for the loss of Mullion Harbour" After noting details of the high cost of these non-listed building repairs costing £150,000 in 2006 and the plan to inspect the site every year, plus spend £5000 on repairs the report went on to say "... When this programme becomes unsustainable the Trust will move to managed retreat, removing the Breakwaters, or allowing them to collapse, whilst trying to consolidate the inner walls. Eventually the harbour will to its original state as a cove on a storm lashed coast." In 2008, a document ("Shifting Shores - Living with a changing coastline") produced by the National Trust highlighted that the increase in coastal erosion could affect 279 km (173miles) of the Trusts coastline in the south west and tidal flooding could affect 852 hectares (2105 acres). It also highlighted their Management Policy which was "working with natural processes wherever possible", and allowing the coast to realign itself when sea defences have to be removed.

In 1931, confirming that no other countries had claimed the reefs, Japan declared it Japanese territory, placing it under the jurisdiction of the Tokyo Metropolis, classifying it as part of the Ogasawara Village, and naming it Okinotorishima. During 1939 and 1941, a foundation was completed for "a lighthouse and a meteorological observation site" but construction was interrupted by the outbreak of World War II. After Japan's defeat, the United States assumed sovereignty over the Ogasawara islands, and returned authority over the islands to Japan in 1968. Between 1987 and 1993 the government of Tokyo and later the central government built steel breakwaters and concrete walls to stop the erosion of Okinotorishima, which today leaves only three of the five rocks that were present in 1939 above water; in 1988 the Japan Marine Science and Technology Center built a marine investigation facility which it has since maintained following typhoon damage. Funding for full repairs was finally allocated in early 2016.

Phoenix caissons under construction, Southampton 1944 With the planning of Operation Overlord at an advanced stage by the summer of 1943, it was accepted that the proposed artificial harbours would need to be prefabricated in the UK and then towed across the English Channel. The need for two separate artificial harbours – one American and one British/Canadian – was agreed at the Quebec Conference in August 1943. An Artificial Harbours Sub-Committee was set up under the Chairmanship of the civil engineer Colin R. White, brother of Sir Bruce White, to advise on the location of the harbour and the form of the breakwater; the Sub-Committee's first meeting was held at the Institution of Civil Engineers (ICE) on 4 August 1943. The minutes of the Sub-Committee's meetings show that initially it was envisaged that bubble breakwaters would be used, then block ships were proposed and finally, due to an insufficient number of block ships being available, a mix of block ships and purpose made concrete caisson units.

Amble grew in the nineteenth century as collieries were opened; and the newly built railway links to the Northumberland coalfields made the town a centre for the sea transport and export of coal. Prior to the development of the harbour, the town was "little more than a hamlet", according to the architectural guides originally compiled by Nikolaus Pevsner. The principal local mineworkings were those at Broomhill and at Radcliffe. The harbour at Amble was the smallest of those that served the coalfields of Northumberland and Durham. It was originally under the control of the Dukes of Northumberland until, in 1837, a port authority – the Warkworth Harbour Commission – was created to supervise improvements. Following consultations with various engineers, the proposals submitted by John Rennie in 1838 were accepted. These included the construction of breakwaters to the north and the south, which were eventually completed in 1849 at a total cost of £116,000. The larger northern breakwater, which was originally in length, was extended in the early part of the 20th century but suffered from the undermining effects of the tide and required shoring with slag brought in from the ironworks of Hartlepool and Middlesbrough.

In October 1941, the Tanggu New Port Harbor Bureau was set up. The original Japanese plan called for laying down a 30 km breakwater; dredging a 13.4 km, 200 m wide shipping channel; building a shiplock at the entrance of the Haihe; and establishing three wharves with 12 berths, for a projected throughput of 27 Mt. The plan was expected to be completed by 1947. Work slowed down as the war started to go wrong for Japan, and resources (in particular, coal) became more and more scarce. By the time of Japan's surrender in 1945, the project was less than half-way completed: the shipping channel had been two-thirds dredged, breakwaters extended 11 km, only one terminal with 700 m of quayside had been completed, and a second terminal and the barge terminal were almost completed. The Shiplock was 85% complete, 11 km of railways had been laid down, and the ship dock (now the Xingang Shipyard) had been established. The First Marine Division landed at Tanggu on 30 September 1945 and accepted the Japanese surrender of Tianjin on 6 October 1945, before transferring control back to the Nationalist government.

The Flemish engineer working for the empress, Franz de Volan (François Sainte de Wollant) recommended the area of Khadzhibei fortress as the site for the region's basic port: it had an ice-free harbor, breakwaters could be cheaply constructed that would render the harbor safe and it would have the capacity to accommodate large fleets. The Namestnik of Yekaterinoslav and Voznesensk, Platon Zubov (one of Catherine's favorites) supported this proposal, and in 1794 Catherine approved the founding of the new port-city and invested the first money in constructing the city. Ivan Martos's statue of the Duc de Richelieu in Odessa However, adjacent to the new official locality, a Moldavian colony already existed, which by the end of the 18th century was an independent settlement named Moldavanka. Some local historians consider that the settlement predates Odessa by about thirty years and assert that the locality was founded by Moldavians who came to build the fortress of Yeni Dunia for the Ottomans and eventually settled in the area in the late 1760s, right next to the settlement of Khadjibey (since 1795 Odessa proper), on what later became the Primorsky Boulevard.
