However, more water is lost from No.1 dock supply if the Basin water is lowered to the seaward side of the lock gates instead of using the Lady Windsor lock sluices. In the early days, the dock operators would often run the water down to bring in a single ship having a wider beam than the Lady Windsor lock could handle.

Even when the source material lacks sufficient elevation, it can be elevated to the sluice by a dredge pump. In the construction of a hydraulic fill dam, the edges of the dam are defined by low embankments or dykes which are built upward as the fill progresses.

Moli'i had five such sluices, and three of the sluices were still in place in 1972 when the pond was listed on the National Register of Historic Places listings in Oahu. This system of harvesting ocean catch was unique to Hawaii, and does not exist within other areas of ancient Polynesia. The wall which partitions the pond from Kaneohe Bay dates back to the earliest Hawaiian settlement of the land, and is traditionally attributed to the Menehune of Hawaiian mythology. The craftsmanship applied in constructing the wall is similar to brickwork, in that the gaps and crevices between the stacked stones are plugged with coral and smaller rocks.

Before the dam was built, Mariental was flooded in 1923 and 1934. However, whenever dam sluices have to be opened fully due to good rains in the Fish River's catchment area, Mariental is still prone to floods, with reed grasses growing in the riverbed of Fish slowing down the flow of water and aggravating the danger. (Full information only in the print version) Floods after the commissioning of the dam occurred in 1972, 1974, 1976, 2000, and 2006.

In 1796 he was made a brigadier-general, and appointed to command the camp at Bandon in Ireland, and on 1 January 1798 he was promoted major-general, and shortly after given the important command of Dover. As Coote held the Dover post he was appointed to command the troops employed in the expedition which had been planned by Sir Home Popham to cut the sluices at Ostend, and thus flood that part of the Netherlands which was then in the possession of the French. The troops were only thirteen hundred in number, and were successfully disembarked and cut the sluices as proposed on 18 May. A high wind off the land then sprang up, and the ships could not come in to take the troops off.

The sluices Jessop's original designs for the harbour included a dam with an 'overfall', with the level of the water determined by the height of the dam's crest. As a result of the accumulation of mud and silt in the harbour, ships entering the narrow harbour were frequently being grounded. In 1832 Brunel was called upon to provide the solution to this problem and designed the sluice system, still in use today, to remove excesses of silt and mud. In place of the Overfall he constructed three shallow sluices and one deep scouring sluice, between the harbour and the New Cut, together with a dredging vessel, known as a drag boat, to scrape the silt away from the quay walls.

Sluicing has also been analyzed in Omani Arabi as is shown in Algryani (2019). All four of the above stated sluicing constructions outlined by Merchant (2001) are accounted for in Omani Arabic. Algryani (2019) displays the different constructions in the following examples: Sluices with Adjunct Wh-Phrases ::Zayd rāḥ, lakǝn ma-adri mita /wein. ::Zayd left.

After various lawsuits and petitions, locals took action during the confusion of the Civil War and flooded Hatfield Chase by raising floodgates and damaging banks and sluices. Riots broke out when the courts finally ruled against them in 1650. Peace was restored, but lawsuits continued for the rest of the century and were not finally resolved until 1719.

The New Cut is an artificial waterway which was constructed between 1804 and 1809 to divert the tidal river Avon through south and east Bristol, England. This was part of the process of constructing Bristol's Floating Harbour, under the supervision of engineer William Jessop. The cut runs from Totterdown Basin at the eastern end of St Phillip's Marsh, near Temple Meads, to the Underfall sluices at Rownham in Hotwells and rejoining the original course of the tidal Avon. The length of the cut is approximately and with the addition of short sections of the original course of the river Avon at either end, connecting Netham weir and Totterdown basin, and the Underfall sluices to the mouth of the Entrance lock at Cumberland Basin, the overall watercourse length is .

The dam's position allowed for a spillway and sluices between the northern end of the dam and the cliffs to the west. Around 500 BC the dam height was increased to 7 meters, the upstream slope (the water face) was reinforced with a cover of stones, and irrigation was extended to include the southern side as well as the northern side. After the end of the Kingdom of Saba', the dam fell under the control of the Ḥimyarites around 115 BC. They undertook further reconstruction, creating a structure 14 meters high with extensive waterworks at both the northern and southern ends, five spillway channels, two masonry-reinforced sluices, a settling pond, and a 1000-meter canal to a distribution tank. These extensive works were not actually finalized until 325 AD and allowed the irrigation of .

The raid had the objectives of destroying the lock-gates and sluices of the Brugge to Ostend canal. The expedition was supported by a bombardment from Royal Navy (RN) warships. The locks were destroyed, but due to unfavourable winds preventing re-embarkation, the 1,300 men of the army contingent under the command of Major General Coote were captured by the French.

The miners would aim the monitors at the hillsides to wash the gravel into huge sluices. Over time the monitors became bigger and more powerful. Their force was so great they could toss a fifty-pound rock like a cannonball or even kill a person. Over 300 Chinese worked on this project and two Chinese settlements existed in North Bloomfield.

Ditches ran between the walls of the marshes, with sluices at the ends where the ditches met the sea. At high water, the island would effectively be divided into a number of smaller islands. A Commission of Sewers was appointed in 1695, whose jurisdiction included Foulness, but the inhabitants were not happy, and engaged the lawyer Sir John Brodrick to put their case.

In total there are 36 culverts, 2 flood-release sluices and 4 road bridges associated with the main canal. A cross sluice was also built at Gaoliangjian苏北灌溉总渠工程 Retrieved January 9, 2015. between the Erhe river and the canal. This is a further flood drainage gate that strengthens the draining capacity of the main canal.

Dobie, Page 326 A sawmill also existed at East Kersland with associated mill pond and settlement ponds and sluices. Originally the mill was fed by water from the old Kersloch near Kerselochmuir, carried to the site in an underground culvert and later by the muir alone. The mill had several dams and three mill ponds which have now been infilled.

The border turns to the south and leaves the river just before it reaches Corn Mill Farm. Here it is joined by a stream from Wallingwells, once the site of Wallingwells Priory and now occupied by a 17th century country house. The house was divided into seven dwellings in 1926. The stream is the outflow of two lakes, connected together by sluices.

In particular, the Jones Falls Dam, built by John Redpath, was completed in 1832 as the largest dam in North America and an engineering marvel. In order to keep the water in control during construction, two sluices, artificial channels for conducting water, were kept open in the dam. The first was near the base of the dam on its east side.

Following a takeover by Liverpool Corporation in 1855, Rendel's plans were implemented, but the sluices failed soon after the docks were completed in 1864. A new Act of Parliament obtained in 1866 authorised the rebuilding of the docks to Abernethy's plans. Throughout this period he was active with other schemes as well, including a shipyard for Messrs. Laird on the River Mersey.

It is tidal below the sluices at New Clyce Bridge in Highbridge. Bow Bridge Bow Bridge is a 15th-century Packhorse bridge over the River Brue in Plox, Bruton. It is a Grade I listed building, and scheduled monument. The bridge may have been built as a link between the former Bruton Abbey, and its courthouse in the High Street.

The width of the aqueduct, towpaths included, is 11.5 meters and its length is 662.7 meters. There is a line of standard lamps on each side of aqueduct. Each end is marked by two ornamental columns in imitation of the Pont Alexandre III in Paris. Eight sluices make it possible to empty the aqueduct in the event of severe freezing.

They freed logs that had jammed at critical points such as sluices, bends, bridges and ox-bows. Later a smaller workforce was employed. Under good conditions it took 10 days for log rafts to reach Celle, otherwise it might take up to 3 weeks. There were 10 assembly points on the Ise where the logs were tied together into rafts.

In the middle go the 15th century additional sluices was built north and south of Nanwang and levees was erected around the reservoirs. The complete project was carried out in several different phases during the period 1411 to 1505. Today the Nanwang water division system is an archaeological site and the excavations began in 2008 when 4,000 square meters were excavated.

The gatehouse and tower are built of stone "rubble" and are two or three storeys high. The arched gateway had a double portcullis, the grooves of which are still visible. The windows are described as "trefoil or cinquefoil headed lights". Under the main tower, the filled in arches of the tidal moat and sluices are visible on both the southern and northern flanks.

The Augustów Canal was the first summit level canal in Central Europe to provide a direct link between the two major rivers, Vistula River through the Biebrza River – a tributary of the Narew River, and the Neman River through its tributary – the Czarna Hancza River, and it provided a link with the Black Sea to the south through the Oginski Canal, Daugava River, Berezina Canal and Dnieper River. From the time it was first built, the canal was described by experts as a technological marvel, with numerous sluices contributing to its aesthetic appeal. The Augustów Canal, consisting of 18 locks and 22 sluices, is divided into two major sections: the West — from the merger of the Biebrza lock Augusta (0.0 – 32.50 km); and the East section — from lock to lock Niemnowo Augusta Belarus (32.50 – 101.20 km).

From Burgh Ferry, boats would use a widened Oulton Dyke to reach Oulton Broad and a new sea lock would be constructed to link the broad to Lake Lothing. This had four sets of gates, so that it could be used at all states of the tide, was capable of holding vessels which were and used a system of sluices to enable the channel through Lake Lothing to be flushed with water from Oulton Broad. Completed in 1829, it was demonstrated in 1831 and although four operations of the sluices were estimated to have removed 10,000 tons of gravel and shingle out to sea, its subsequent operation was not as effective. In the other direction, construction of Haddiscoe Cut began, to link the river at Haddiscoe to the River Yare at Reedham, enabling vessels from Norwich to bypass Yarmouth.

Short residential streets in north- eastern Staines upon Thames were flooded in February 2014. At least 80 homes reported internal, outhouse or grounds flooding to the Environment Agency. Causes were complicated by the interweaving of an aqueduct which overflowed and various sluices; one found to be inadequate, another not best-operated. A precedent for the river was in 1947 when flooding was widespread in the Thames Valley.

Once the water had been drained by sluices the damp caked earth was carried in wooden trams to kilns where it was dried for three to four days. The product was used in the oil refining and pharmaceutical industries. The original uses in woollen production no longer used fuller's earth. A railway siding at Midford railway station was built specifically to load fuller's earth.

The main road connecting between channagiri and Davanagere pass through on this embankment. It has resisted successfully the floods of centuries, but owing to the great pressure of the volume of the water in tank.Mysore: a gazetteer compiled for government, Vol 2 Page No. 482 Google Books Online It has two sluices. That to the north is called the "Sidda", and that to the south the "Basava".

Notwithstanding the damaged state of the sluices and the great force of the water when escaping through them, the embankment has always remained firm and uninjured, a satisfactory proof of the solidity of the structure.Mysore: a gazetteer compiled for government, Vol 2 Page No. 482 Google Books Online If required (as during drought) the tank can be fed by surplus water from Bhadra Dam's right bank canal.

Historically mercury, otherwise called "quicksilver" was used during the mining process. During hydraulic mining when the water, slurry, and debris flowed over the sluices and drainage tunnels, the particles were also mixed with liquid mercury. The mercury was used during the extraction period during the mining process. The mercury was used to attract the gold and sometimes silver from the mining ore, for extraction.

It included the long section between Timișoara (now in Romania) and Klek (now in Serbia). The river was previously used for dumping of the wastewater. Four complexes of locks-sluices were built from 1910 to 1912 which allowed for constant navigation, regardless of the periods of low water levels. Today two are in Romania (Sânmihaiu Român, Sânmartinu Maghiar) and two are in Serbia (Itebej, Klek).

Although this was heading up the dale, the passage had a slight fall to the North, to encourage the water flow. At the pump shaft, the shaft was now deep. This tunnel was just one of a number of culverts, sluices and similar works built at the Coalbrookdale site around this time. The engine had a working life of just less than forty years.

It is this document from 1255 that is referred to in the painting by Caesar van Everdingen in 1654. From that point on, the heemraden at Spaarndam were called the heemraden van Rijnland. This would not be the last time that the city of Haarlem got into an argument with the Hoogheemraadschap van Rijnland. In 1514 a heavy storm broke the sluices and the dike at Spaarndam.

The sluices are of two types; some for the normal river releases and some for flood management purposes. The dam is designed to handle floods of up to 14200 m³/s. After the raising of the dam in 1967, it has a storage capacity of 45 million m³. It diverts water into a concrete lined canal on the right flank with a capacity of 40 m³/s.

Churchill dispatched the following message to Gort: > 1\. That the Belgian Army should withdraw to the line of the Yser and stand > there, the sluices being opened. > 2\. That the British Army and French 1st Army should attack south-west > toward Bapaume and Cambrai at the earliest moment, certainly tomorrow, with > about eight divisions, and with the Belgian Cavalry Corps on the right of > the British.

Utrecht has an industrial port located on the Amsterdam-Rijnkanaal. The container terminal has a capacity of 80,000 containers a year. In 2003, the port facilitated the transport of four million tons of cargo; mostly sand, gravel, fertiliser and fodder. Additionally, some tourist boat trips are organised from various places on the Oudegracht; and the city is connected to touristic shipping routes through sluices.

He created the "scrape", an area with shallow water, islands and bare mud, by lowering land levels and managing the water level with new sluices. A circular path led around the scrape, giving access to hides on each of the four sides. In 1977, two years after Axell's retirement, the RSPB purchased the reserve outright. The Great Storm of 1987 destroyed 3,000 trees in one night.

An Act to enclose the fen land in the parish of Branston was obtained in 1765, and another for the parish of Potterhanworth in 1774. This also gave the Commissioners powers to build banks, engines and sluices. A third Act was obtained in 1789, which authorised the embanking of in Nocton, Potterhanworth and Branston. It included provision for enlarging the Car Dyke, and raising its eastern bank.

In the case of placer mining, unconsolidated gravel, or alluvium, is fed into machinery consisting of a hopper and a shaking screen or trommel which frees the desired minerals from the waste gravel. The minerals are then concentrated using sluices or jigs. Large drills are used to sink shafts, excavate stopes, and obtain samples for analysis. Trams are used to transport miners, minerals and waste.

Landscaped in 1925 by Col. Gavin Jones for F.J. Nettlefold, this 'lost' forest garden is situated in a remote, secluded steep-sided valley near Wych Cross. It was acquired by the conservators in 1994 and is now undergoing restoration. Already uncovered are a 250 metre gorge constructed using limestone brought from Cheddar Gorge, many unusual trees and a string of small lakes connected by sluices and weirs.

On the construction of the Shannon hydroelectric scheme in 1925-9, the lake became a storage reservoir for the power station nearly 100 miles away, with sluices to control the flow into the river. This helps to maintain the flow during dry periods and manage flooding at other times. It made the Lough Allen Canal, which was rarely used by this time, unusable until restored in 1996.

Its total length is about . Silver Stream is the site of a historic water race. The Silver Stream Water Race was built between 1877 and 1881, and consisted of nearly of open races, sluices, tunnels, and weirs. The race began at a weir high on the river and traversed the sides of Swampy Summit and Flagstaff before emptying into a reservoir in Kaikorai Valley.

From here the river feeds a system of ponds and sluices in an area known as the Grove. Many drains feed into the river here. The river now turns almost south and passes under another lane called Cromer Road and crosses countryside towards Ash Tree Farm and Ash Plantation. The river now widens slightly and begins to cross open countryside, slowly turning south east again.

Hydroproject headquarters Hydroproject (, Gidroproekt) is a Russian hydrotechnical design firm. Based in Moscow, it has a number of branches around the country. Its main activities are design of dams, hydroelectric stations, canals, sluices, etc.Hydroproject website Hydroproject and its predecessor institutions have designed most of the hydroelectric dams and irrigation and navigation canals that have been built in the Soviet Union and Russia since the 1930s.

Along with furniture (based on the original repertoire of his forefathers) for the royal palaces he also designed and built many structures in the city. Amongst these were typical Dutch specialities such as drawbridges, sluices, windmills and canals. He enhanced the Summer Gardens with fountains which were fed by a complex network of underground water tanks. He was also involved in large infrastructure projects around Saint Petersburg.

Taungoo troops began their final push the very next day. They overcame Arakanese defenses, and breached the eastern outworks of Mrauk U. But Min Bin opened the sluices of the city's reservoirs, flooding out many Taungoo troops and creating an impassable moat. Taungoo forces were now reduced to shelling from afar. But their Portuguese supplied cannon had little effect against Mrauk U's stone walls.

The lower part, the Hanami, ranges from the Ōwada Drainage Pump Station in Yachiyo City, and drains into Tokyo Bay in the Mihama Ward of Chiba City. The lower part of the river where the Hanami empties into Tokyo Bay is known as the . Numerous sluices have been built on the Hanami to protect the surrounding area from damage due to high tides and typhoons.

The paddles were designed like weir sluices, and take many turns to open them. A weir was built at the lock to control the river level. Around the same time the top gates were replaced the weir was replaced by an automatically controlled structure. There is a small building next to the weir which houses water level meter, and control systems for the weir.

However, as a result of the silt flushing, some detrimental effect on the biota was noted by local people of the area in the downstream reaches of the river below the dam. The effectiveness of the flushing operations has been studied over the years by hydrographic surveys of the reservoir using turbidimeters, side scan sonar, sub-bottom profiler, repeated echo sounding, sediment coring and X-ray techniques. The studies have indicated that the sluices provided in the dam to flush the sediment deposits in the reservoir are effective given the "duration and degree to which the reservoir is drawn down and on the discharge capacity of the sluices" and also the shape of the reservoir, which in the case of Cachi is in a narrow gorge. Studies indicated that the average diameter of the sediments deposited in the reservoir was of the order of 0.04 mm.

The Schlussdorf-Winkelmoorer Schiffgraben measures in length and connects via the river Umbeck to the Hamme. Ten sluices regulated its water level which in 1854 were combined in pairs to form chambers similar to locks able to include up to eight turf barges, obliged to pass in queues to reduce water outflow. Flap weir while accessed by a turf barge pressing down the weir's leather-enforced blades else upheld by the headwater behind it, early 20th century Since passing sluices is time-consuming, with – in the 1870s – 1,500 turf barges in the Teufelsmoor making up for 9,000 passages per year at, e.g., the Ritterhude Lock, tinkerers plotted a remedy. The canal steward () Müller from invented the (flap weir)Johannes Rehder-Plümpe, „Die Struktur der Findorff-Siedlungen“, in: Die Findorff-Siedlungen im Teufelsmoor bei Worpswede: Ein Heimatbuch, Wolfgang Konukiewitz and Dieter Weiser (eds.), 2nd, revis. ed.

As a result of the North Sea flood of 1953 the Haringvliet was closed off by the Haringvlietdam. The Haringvliet lost its estuarine characteristics and became a freshwater lake. Because of that, the seals are gone and migrating fish can only enter the Rhine-Meuse Delta through the busy and heavy industrialised Nieuwe Waterweg. There are plans to permanently open a few of the Haringvliet sluices, to partly restore the ecosystem.

At this depth, the miners face both the danger of collapse and high temperatures. The mines will tackle finds that may stretch for half a mile and this may involve 300 people working together. Regular work for boys is to carry large quantities of water from the river in plastic jugs so that gold may be extracted. The ore and water are run over sluices which are lined with carpet.

One of the main, and also most destructive methods was that of hydraulic mining. This involved the redirecting of water from the river into a narrow channel, into a large canvas hose, and iron nozzle. Then these water canons which were called monitors it would shoot a very high pressure stream that would break apart hillsides. The water, slurry, and debris, mostly gravel would flow over large sluices and drainage tunnels.

Later in the summer of 1899 human powered equipment like sluices and rockers were present.Alaska Gold, Gold Rush Stories, retrieved 2011-12-21 In 1900 small machines together with hoses and pumps were seen at the beach, and finally from around 1902 big companies took over.Explore North, retrieved 2011-12-21 The season wasn't long. Due to ice, the beaches could only be worked from June to October.

It was improved during the reforming governorship of Sir George Don, when it was "deepened, widened, and confined within walls of masonry, with regular sluices, by which means the whole can be let out and the place cleansed."Buckingham, p. 47 By 1840, it was clean enough to be "well stocked with grey mullet",Wilkie, p. 381 though only the soldiers of the garrison were permitted to fish there.

Haarlem was happy to have the free passage of ships and refused to repair the dike. When the Hof van Holland decided in favor of repairs, Haarlem asked to have the dam (and sluices with their tolls) moved closer to the city. This would mean that Haarlem would have the dam on its own property, and they would have more control. The heemraden voted against it, and repairs were ordered.

His mission was to seize important buildings of the Communist Party, including the NKVD headquarters at Lubyanka, and the central telegraph office and other high priority facilities, before they could be destroyed. He was also ordered to capture the sluices of the Moscow-Volga Canal because Hitler wanted to turn Moscow into a huge artificial lake by opening them.Ganzenmüller, Jörg (18 July 2011). Blockade Leningrads: Hunger als Waffe.

Godesburg, a fortress a few kilometers from the Elector's capital city of Bonn, was taken by storm in late 1583 after a brutal month- long siege; when Bavarian cannonades failed to break the bastions, sappers tunneled under the thick walls and blew up the fortifications from below. The Catholic Archbishop's forces still could not break through the remains of the fortifications, so they crawled through the garderobe sluices Ernst Weyden.

Several day spas utilising mineral water are located in the township as well a wide range of restaurants, cafe, hotels, guest houses and accommodation options. The town is surrounded by the Hepburn Regional Park. There are many opportunities for short or long bushwalks, often along old gold mining water sluices and peppered by mineral springs. Playgrounds are found at the Hepburn Mineral Spring Reserve and at the Laurie Sullivan Recreation Reserve.

There are two feeder channels, two sluices, and two surplus courses for the Kapra Lake, this lake being part of a chain of water bodies, wherein the surplus course of the upper water body flows down into the lower water body. Thus, the Kapra Lake is intimately linked in the chain of the R.K. Puram lake, the Annarayan Cheruvu of Nagaram and the Yadi Bai Gunta of Yellareddy Guda.

To work on the sluices and the waterwheel the leat was dammed. Specialist wood and metal work was undertaken by apprentices from the British Aircraft Corporation in Filton. By 1972 some progress had been made; John Butt retired and Derrick Dudden took over as restoration manager, with more volunteers from the Canal Trust helping to provide the labour. Silt was removed from the pond, hatches replaced and the waterwheel restored.

The river was rapidly becoming unsuitable for trout. Sawyer undertook a major project in the early 1950s known as "the great clean up". This involved dredging the worst-hit areas of the river to remove mud and silt, and return the bed to chalk and gravel. Old sluices and hatch gates that impounded or reduced flow were removed to speed up the flow and scour the beds clear of filth.

It passes under Water Street, and then surfaces to run beside the canal. Some old sluices once controlled the flow to Mill Dam, which supplied the water for Millfields Mill, just above Coach Street.Ordnance Survey, 1:1056 Map, 1852, available here In 1822, the mill was occupied by James Wilson, a spinner of worsted. The lower floor was used as a paper glazing mill, but from the 1840s, Messrs.

By the late 1960s the tank's bund was long and high whilst the tank's storage capacity was and its water spread area was . There was a channel flow spill on the right bank and seven sluices. Water from the tank was transferred to numerous minor irrigation tanks via a main channel and of branch channels. The tank's storage capacity was in 2003 and it was capable of irrigating .

The process was inadequate for the volumes entering the works, and the canal became increasingly polluted. Consideration was given to discharging the effluent into the tidal River Mersey, by construction of a culvert to Randall's sluices, near Warrington, or treating it by the use of septic tanks and double-contact bacteria beds. The second option was chosen, as the first would have reduced the flow in the Ship Canal.

These eleven bays consist of eleven water tunnels (sluices), each in length, in height, and in width. These are located at different levels, with seven main bays at the lowest level. The balance two additional bays on each bank, on the far east and west sides, are at a higher level. The control arrangements seen now are in the form of gate grooves to operate vertical slide gates.

A rural band of the village adjoins the River Wey including Cartbridge and Send Marsh – this land has been drained and the river tamed by sluices, the Broadmead Cut and the Wey Navigation. The vast majority of the built-up areas are not within an area of flood risk. Between the river and the navigation, in the far north of the parish, are the Papercourt and Broad Mead SSSIs.

However, after the immigrant is in custody, Faes is told the man might have a viral infection, so Jokke is ordered to remain at the center. Subsequently, the city neighborhood around the center is sealed off from the outside world to contain the virus. Shipping containers are placed across the entrance to all road junctions. Three gates (sluices) control access through which medical supplies and food are sent.

A possible worn grindstone set into the church wall near the door. The 1856 OS map alone shows a dam and mill pond on the Stroquhairn Burn with sluices and a mill race running down to Kirkbride Farm with the water then leaving via an unnamed burn to join the Ha Cleuch Burn. A very worn grindstone is incorporated into the south wall of the church near the door.

The captives included John MacKellar of the frigate , and his boat crew. The sluices were repaired within weeks. Druid sailed to the Mediterranean in 1801 to support operations in Egypt. Because Druid served in the navy's Egyptian campaign between 8 March 1801 and 2 September, her officers and crew qualified for the clasp "Egypt" to the Naval General Service Medal that the Admiralty authorised in 1850 for all surviving claimants.

Governor Zacharias Wagenaer was very concerned about providing regular drinking water to inhabitants and visiting ship crews alike. He ordered a rectangular masonry dam, known as the New Bowl (or also Wagener's Tank), to be built between the Fort and the ocean. Soldiers, gardeners, slaves, boys, and girls, essentially everyone in the settlement, worked to dig up and break the bedrock. Afterwards, masons finished the walls and sluices.

Sluices were created at both ends to allow surface water to drain at low tide. The whole of the work being undertaken using men, with horse and carts to transport the materials. The work was completed in 1808 and on completion, Mr Henry was presented with a sword by Lieutenant-General Sir John Doyle. In 1812 damage was found to have been caused to the Vale church embankment from storms.

The canal cuts in the Ise valley left artificial ox-bows. Wooden sluices with sluice channels were built at Wahrenholz and Gifhorn. The first test run was carried out in 1659 and timber rafting officially began on the Ise in 1661 when 4,400 stères of wood fuel was transported to Gifhorn and from there down the Aller to Celle. To begin with 100 men were employed on the task.

In October 1914, Geeraert came in touch with a Belgian detachment of marine engineers (sapper) guarding the sluices in Nieuwpoort. On 21 October they were ordered by their High Command to flood the polder at to protect the endangered bridgehead at Lombardsijde. Geeraert contributed to the success of the operation. This was, however, a temporary respite and on 25 October they decided to flood the entire region between Nieuwpoort and Diksmuide.

The river formerly joined the River Mersey at Weston Marsh, but since the construction of the Manchester Ship Canal, begun in 1887, it has flowed into the canal, from where surplus water enters the Mersey by the Weaver sluices, just upstream of the junction. The tidal river section below Frodsham has been bypassed by the Weston Canal since 1810, and is no longer navigable, as Frodsham Lock is derelict.

First envisaged in 1897, Hardap Dam is Namibia's largest dam with a capacity of and a surface area of . Construction began in 1960 and completed in 1963. Hardap Dam supplies Mariental and the surrounding settlements with potable water. Its location close to the city, however, also poses a danger of flooding it when sluices have to be opened fully due to good rains in the Fish River's catchment area.

The stream has provided power for watermills and battery mills in the past and some mill buildings still survive. Wildlife is supported by nature reserves through which the Siston Brook runs. Flooding has caused problems in the past, but modern measures to alleviate this include an attenuation reservoir and proposals to reinstate historic weirs and sluices. The name Siston is believed to derive from Anglo-Saxon, meaning Sige's Farmstead.

Ptolemy II Philadelphus's lifespan was 309 BC–246 BC. and constructed a navigable lock, with sluices, between the Heroopolite Gulf and the Red Sea so as to allow the passage of vessels but prevent salt water from the Red Sea from mingling with the fresh water in the canal. Ancient cities which were at one time situated along the coastline of the Heroopolite Gulf include Arsinoe, Heroopolis and Olbia.

"De Hoop" mill The village is located at the west side of the Afsluitdijk: therefore the Stevin lock (named after mathematician and engineer Simon Stevin) and three series of five sluices for discharging the IJsselmeer into the Wadden Sea were constructed in Den Oever. In 2001, the town of Den Oever had 2286 inhabitants. The built-up area of the town was 0.53 km², and contained 938 residences.Statistics Netherlands (CBS), Bevolkingskernen in Nederland 2001 .

It is closed off near Goedereede from the North Sea by the Haringvlietdam, which provides a road connection between the island of Voorne to the north and the island of Goeree-Overflakkee to the south. The dam with its sluices was built as part of the Delta Works sea barrier protection works. The Haringvliet estuary contains the island of Tiengemeten, which is separated from the river island of Hoeksche Waard by the Vuile Gat strait.

The most significant feature of the Marsh is the Rhee Wall (Rhee is a word for river), forming a prominent ridge. This feature was extended as a waterway in three stages from Appledore to New Romney in the 13th century. Sluices controlled the flow of water, which was then released to flush silt from the harbour at New Romney. Ultimately, the battle was lost; the harbour silted up and New Romney declined in importance.

Commercial fishing operations are contracted out. Ancient Hawaiian fishponds were noted in the 1826 journal of William Ellis, the naturalist on James Cook's third voyage (1776–1779): Moli'i, along with Huilua, Kahaluu and Heeia are the only four original Hawaiian fishponds remaining on Oahu. Fishponds were used by the ancient Hawaiians for ocean husbandry. Each pond had a set of sluices that controlled the seawater flow and the fish available in the pond for harvesting.

The lake was created as a buffer between the old land of the Veluwe and the newly created Flevopolder, to ensure that the water level of the Veluwe would not drop. The lake receives water from the neighboring Veluwemeer and several streams and sluices. An additional source is low-phosphate water from the Flevopolder to counter eutrophication. The Wolderwijd lake is used for commercial fishery, boating, shipping traffic, water management, and sand extraction.

In the end, the growers decide to flood the fields without permission, whilst a delegation sets out for Ankara to obtain Irmaklï's dismissal. At the same time Zeyno and the peasant women, covered in mud from head to foot, demand the right to live in human conditions. To save the village, the women have resolved to use their shovels to block the sluices. Okçuoglu offers money to the peasants if they will leave their homes.

Souham had opened the town sluices, which slowly inundated the fields connecting York to Freytag and filled British trenches on the dunes with two feet of water.Fortescue p. 234 "The inundations increasing daily, rendered the ground, on which the British encamped, a perfect swamp", and soon "An epidemical disorder called the Dunkirk Fever, soon broke out amongst the troops, increased daily, and carried off the soldiers rapidly".Officer of the Guards I p.

In the fertile agricultural areas near the Tungabhadra River, canals were dug to guide the river water into irrigation tanks. These canals had sluices that were opened and closed to control the water flow. In other areas the administration encouraged the digging of wells monitored by administrative authorities. Large tanks in the capital city were constructed with royal patronage while smaller tanks were funded by wealthy individuals to gain social and religious merit.

The Tirmidh garrison, however, managed to defeat Harith, who retired eastwards to the mountains of Badakhshan. Asad followed up this success by persuading the garrison of Zamm to surrender on promises of amnesty and double pay. Asad then led an expedition to recover Samarkand, which had been lost in the aftermath of the Defile. He failed to take the city, and returned to Balkh after destroying the sluices of the city's irrigation canals.

Water is also used for numerous small towns including Vryburg, Hartswater, Jan Kempdorp, Warrenton, Winsorton, Kipdam, Barkly West and Delportshoop. The main construction of the weir was completed in 1938 and was part of the government initiatives to alleviate unemployment following the depression of the 1930s. In 1967, the weir was raised by 1.2m to its current height of 11m. It is a concrete barrage-type structure, 765m wide with numerous sluices.

One-fourth to one- third of the state's property was destroyed, and one home in eight was carried away or ruined by the flood-waters. Mining equipment such as sluices, flumes, wheels and derricks were carried away across the state. An early estimate of property damage was $10 million. However, later it was estimated that approximately one-quarter of the taxable real estate in the state of California was destroyed in the flood.

The River Loddon is a tributary of the River Thames in southern England. It rises at Basingstoke in Hampshire and flows northwards for to meet the Thames at Wargrave in Berkshire. Together, the Loddon and its tributaries drain an area of . The river had many active mills, and has many remnants of flow modifications by the building up of mill pond reaches with weirs and sluices and the adjacent mill races (also called leats).

Epanchoir a siphon Siphon sluices () are one of the many water management devices used on the Canal du Midi to regulate the level of the water. The siphon acts as an automatic water level regulator. The épanchoir à siphon, or siphon sluice, was designed by Bertrand Garripuy (Garipuy) Jr., the son of the chief engineer. The first épanchoir siphon was built in 1776 near Capestang and the second in 1778 at Ventenac.

This brought outside investors into the business of removing gold from the gulch. They wanted the quickest return possible on their investment and they encouraged unrestricted use of hydraulic methods. The powerful jets of water used in hydraulic mining washed down whole hillsides and simply ate up the floor of the gulch. The dirt and fine gravel was then washed through the sluices, and the silt was carried off down the gulch.

The route diagram shows the waterways as they existed in 1880. The Upper Forge, New Mills and Middle Forge all had extensive ponds upstream of the works, contained by stone dams. Once the canal closed, the ponds covered its route between Upper Forge and Middle Forge. Ordnance Survey maps for the period show weirs and sluices at the downstream ends of the ponds, and the central one at Middle Forge appears to feed the canal.

The mean tidal range at the Leda Sluice is three metres. It is still 80 centimeters on the Drey Drain, a cross- connection between Leda and Jümme in the district Barge in southeastern Samtgemeinde territory.[7] Flood control, dyke safety and drainage are the responsibility of the Leda-Jümme association, which is based in Leer. Apart from the dikes and the sluices, the Association has five large controlled- discharge polders, essentially storm water overflow ponds.

Navigation and farmland were threatened upstream along with the relocation of an additional one million people. Despite the dam's 12 deep-sluices and alterations in the release of water, silt continued to build in the reservoir, particularly in the back waters. Responding to the potential crisis, a meeting was held in December 1964 with Premier Zhou Enlai. At the meeting, it was decided to reconstruct the dam's outlet works for improved discharges and silt control.

The renovation was carried out immediately and in two stages. The first stage included the installation of two tunnels on the dam's left bank at an elevation of ASL along with converting four penstocks into flushing pipes. The flushing pipes began operating in 1966 and the tunnels in 1967 and 1968. In the second stage, eight bottom sluices were added to the left side of the dam which became operational between 1970 and 1971.

Most were buried beneath the ground, and followed its contours; obstructing peaks were circumvented or, less often, tunnelled through. Where valleys or lowlands intervened, the conduit was carried on bridgework, or its contents fed into high-pressure lead, ceramic or stone pipes and siphoned across. Most aqueduct systems included sedimentation tanks, sluices and distribution tanks to regulate the supply at need. Rome's first aqueduct supplied a water-fountain sited at the city's cattle market.

300 Attempts to inundate the Island of Dordrecht failed, as the inlet sluices could not be opened—and were too small anyway.De Jong (1970), p. 301 The Light Division tried to cut the German corridor by advancing to the west and linking up with a small ferry bridgehead over the Dortse Kil. However, two of the four battalions available were inefficiently deployed in a failed effort to recapture the suburbs of Dordrecht;Amersfoort (2005), p.

Sluices and other techniques used to acquire gold dust contributed to the degradation of fish habitat in the Klamath River basin, in addition to causing other environmental destruction of the watershed. The irregular contact with European descendants became far more frequent by the 1840s. Military forces of the United States conquered Alta California during the Mexican–American War. American control was initially limited to areas that had been administered by the Mexican government.

Newmans Sluices on the River Lee Flood Relief Channel, pictured on a day of strong water flow The Lee Flood Relief Channel (FRC) is located in the Lea Valley and flows between Ware, Hertfordshire, and Stratford, east London. Work started on the channel in 1947 following major flooding and it was fully operational by 1976. The channel incorporates existing watercourses, lakes, and new channels. Water from the channel feeds the Lee Valley Reservoir Chain.

Fishermen petitioned Doyle on the basis that they had lost their mooring facilities. They were successful and a pier was built at Les Amarreurs at a cost of £60 for their use. The owners of the reclaimed land were given an obligation to keep the Great Bridge, sluices and douits (ditches) maintained, although this obligation ended in 1872. The area of land in Guernsey materially increased with the tidal channel being turned into profitable meadows.

The Carrigadrohid hydroelectric plant, along with its sister plant constructed downstream on the River Lee at Inniscarra, formed the fourth major hydroelectric development undertaken by ESB. Construction of the reinforced concrete gravity dam started in 1952 and was complete in 1957. The dam is long and high, and operates with an average head of . It is constructed of nine blocks, each between in length, and is fitted with three ground sluices and a spillway weir.

In fact, the only times that the complex was not underwater was when the dam's sluices were open from July to October. It was proposed that the temples be relocated, piece by piece, to nearby islands, such as Bigeh or Elephantine. However, the temples' foundations and other architectural supporting structures were strengthened instead. Although the buildings were physically secure, the island's attractive vegetation and the colors of the temples' reliefs were washed away.

Sickles were used for harvesting mature rice paddies. Since the rivers of the region were not perennial, several irrigation techniques were developed to ensure an adequate and continuous supply of water. Farmers used a bullock- propelled device called Kapilai for bailing out water from deep wells and a manual setup called Erram, for shallow wells. Tanks, lakes and dams were used as water storage systems and the water regulated using sluices and shutters.

Thapar (2003), p378 The highlands (malnad regions) with its temperate climate was suitable for raising cattle and the planting of orchards and spices. Paddy and corn were staple crops in the tropical plains (Bailnad). The Hoysalas collected taxes on irrigation systems including tanks, reservoirs with sluices, canals and wells which were built and maintained at the expense of local villagers. Irrigation tanks such as Vishnusagara, Shantisagara, Ballalarayasagara were created at the expense of the state.

In 1986, the government completed the 8-km-long West Sea Barrage, with three locks and 36 sluices, at the mouth of the Taedong River near Namp'o. The dam acts to control floodwater and to irrigate lands newly reclaimed from the Korea Gulf. The dam has reduced the river's natural ability to purify itself and tends to concentrate contaminants.Tenenbaum, David J. (2005) "International Health: North Korean Catastrophe" Environmental Health Perspectives 113(1): p.

It was forbidden to obstruct the race or the sluice. On the first Sunday of each January, April, July and October all the sluices must be open all day. In September the mill-race and canal must be thoroughly cleaned. 1824: The land register names the Widow of Michel Franck as owner. 1876: A new mill building was built (the door lintel was dated and initialled MP 1881 ML) with a turbine underneath.

Moresk Viaduct from Daubuz Moors Daubuz Moors commemorates Lewis Charles Daubuz, a local resident of French Huguenot extraction whose family owned the tin smelters at Carvedras. For many years, the area was grazed by cattle and sheep, but successive generations have also used it for recreation. At its southern end once stood Moresk Mill, which produced flour throughout most of the 19th century. Powered by water, the remains of its leat, millpool and sluices are still evident.

The immense water-power of the River Mourne provided 1000 water horsepower. The water-power and its history are still very much a feature of the Mill with the modern turbines, the newly developed river walks and picnic areas overlooking the huge weir and the 35 ft wide mill lade which flows on to run between the two main buildings of the Mill. There is also a complicated system of sluices and a suspension bridge ("the swinging bridge").

Sluices and castella aquae (distribution tanks) regulated the supply to individual destinations. In cities and towns, the run-off water from aqueducts scoured the drains and sewers. Rome's first aqueduct was built in 312 BC, and supplied a water fountain at the city's cattle market. By the 3rd century AD, the city had eleven aqueducts, sustaining a population of over a million in a water- extravagant economy; most of the water supplied the city's many public baths.

Th dam consists of eight spillways, each with a width and height of and , which automatically opens when water levels are high. The dam's gates, which needs power only to close, won an award for "Innovative Design in Civil Engineering" by the Institution of Civil Engineers. The total effective width of the spillways is , allowing a maximum discharge of . Two additional low- level sluices at the base of the dam allows the purging of accumulated silts behind the dam.

Carew Tidal Mill (), also called the French Mill, is a corn mill in Pembrokeshire, Wales, powered by tidal water. It was built around 1801 just west of Carew Castle, and replaced a much older mill in the same location. The mill pond fills through open flood gates as the tide comes in. The gates are closed at high tide, and the pond drains through sluices under the mill as the tide falls, driving two undershot water wheels.

The barracks on the island could hold 80 soldiers and house six cannons. The town was drained with tidal sluices to prevent the flooding of the town by sea water. This new capital on St Mary's Island was initially called Leopold, but the name was shortly afterwards changed to Bathurst by MacCarthy, under whom the town was designed. The name was taken from Earl Bathurst, who was then the Secretary of State for War and the Colonies.

The mill races and sluices have survived, and some of the machinery is still in situ, but most is missing. The first known miller was Robert Hawkins who insured the brick and tiled grist mill and mill tackle for £200 in 1767. In the 1910s the wooden buckets on the wheel were replaced with iron ones, which were not particularly suitable because of their weight. The wheel was supplemented by a steam engine, located in another building.

Sugar competitor Claus Spreckels had obtained another lease from the Kingdom government, so unless Baldwin completed his system by September 30, 1878, the water would go to Spreckels. Besides actual ditches lined with clay, sluices and siphons were used to cross several steep canyons. Baldwin would lower himself down into the gulches daily with his one remaining arm. Workers doubted that water would go down through a pipe and then go uphill on the other side.

The events of 1869 did not permanently dissuade some Chinese from remaining in the county. After Unionville declined as a white mining center, scattered Chinese returned to mine the surrounding environs. Because water was at premium in the area, Chinese miners used rockers rather than sluices at their sites. As late as 1905 there were still Chinese miners that continued to work in the American Canyon, but by that time they were quite elderly and numbered fewer than ten.

The river is navigable to Bawtry, and there is a statutory right of navigation as far upstream as East Retford, although access to the river through the entrance sluices is very expensive. Its drainage functions are managed by the Environment Agency, but there is no navigation authority. The river is important for conservation, with the Idle Washlands and some of the sand and gravel pits of the Idle Valley being designated Sites of Special Scientific Interest.

Saluda Factory Historic District is a national historic district located at West Columbia, Lexington County, South Carolina. It encompasses three contributing sites associated with the development of the area along the Saluda River; Saluda Factory, Camp Sorghum and old State Road. The Saluda Factory ruins consist of the granite foundation and sluices from a textile mill that operated on the river between the years 1834 and 1884. The Camp Sorghum site was the site of a Confederate prison camp.

St. George's Anglican Cathedral Georgetown is laid out in a north–south, east–west grid, interlaced with canals protected by kokers (sluices), built by the Dutch and later the British that provide drainage to a city that lies below high-tide level. A long sea wall helps prevent flooding. The city has numerous boulevards and contains many wooden colonial buildings and markets. Most of the main buildings are centred around the western region of the town.

The water passes over depressing sluices which can be raised or lowered by hand cranking, and then powers a breastshot water wheel. The wide wheel is in two sections each wide and in diameter with a gap between them. The wheel has 48 wooden starts on each of the six cast iron rims. These starts support 96 float boards each of which is by by , and is paired with a seal seal board bolted directly to the rim.

The remaining structure is a moated motte; an extensively modified natural mound, rising from the bottom of the ditch to the platform, which is around across. This is surrounded by a system of banks, ditches, dams and sluices which held water until drained in 1823. The remains of buildings on the platform include a thick curtain wall, and the foundations of a church. The latter was in use as the parish church as late as the 17th century.

Seven fuel tanks, four to the left and three to the right, containing 1,260 litres, gave it a range of 150 kilometres. The suspension contained thirty-nine interleaving road wheels on each side, making for a total of ninety wheels on the tank. Designed to negotiate the challenging terrain of trench warfare, the type had in principle excellent mobility. The Char 2C could cross a trench 425 centimetres wide, enough to pass the typical canal sluices in northern France.

During the period of Islamic Hispania (al-Andalus 711–1492) some sluices, irrigation canals and ponds were built. There was probably a pirate base in this district from the last years of the IX century. There are historical documentary references to Berbers taking refuge here in the 16th century, at a time when the Iberian Peninsula had already been reconquered. There is evidence of the existence of simplified almadraba tuna- fishing traps, called tunairas, in the 15th century.

Little Bačka Canal in 200px Little Bačka Canal near 200px Little Bačka Canal (Serbian: Мали бачки канал/Mali bački kanal), (Hungarian: Ferenc József- csatorna) is a canal in Serbia which runs from Mali Stapar (on Great Bačka Canal) to Novi Sad (on Danube). The canal is 66 km long and it is part of Danube-Tisa-Danube Canal system. The canal shortens waterway from Bezdan to Novi Sad by 75 km. Little Bačka Canal has 4 sluices.

It consists of two parallel earth banks, from 50 to 100 metres apart, the ground between being raised above the marsh on either side. It was built in the 13th century: a watercourse was constructed from Appledore to Old Romney, which was extended in 1258 to New Romney. The purpose was to wash away silt from the harbour at New Romney; there were sluices to control the flow at Appledore, Snargate and New Romney. However, the silt at New Romney continued to accumulate.

As there was no money to pay for the works, the Adventurers were to be given land from that which had been drained in recompense. They spent around £30,000, and were given , which yielded rent of £8,000 per year. A further £20,000 was spent on improving the land they had been given. Not everyone was in favour of the work, as in 1642 many of those who formerly had common rights to the land formed a mob, and destroyed sluices, houses and crops.

Ash collected at the bottom of the boilers when in the coal burn regime and was removed after quenching by water sluices. Two crushers were fitted on each boiler to reduce any large ash to a manageable slurry. Dust and grit from the precipitator that cleansed the flue gases was collected in either a wet or dry state and was either discharged to dust hoppers for resale or pumped out as slurry to lagoons on the east side of the station.

According to Jarvis, "these small, hot, dry, and barren islands" were perfect for salt production since the limestone, absence of fresh water, and limited rain fall combined to make the soil unfertile. Yet, average temperatures in the eighties Fahrenheit and the eastern trade wind facilitated evaporation of sea water into a saturated brine for salt crystallized. Natural ponds were augmented with sluices and causeways. Salt originating from this province was cherished for its "brilliant color, purity, and versatility," according to Jarvis.

The length of the dam at the crest is about . In the periphery of the dam six saddle dams have been built which together measure and with varying heights of . To pass the design flood discharge two spillway structures have been built. To release water for irrigation to the canal system low level sluices have been built at the downstream toe of the dam with two control valves of the Howell-Bunger type which function as energy dissipation bypass valves.

Because of these lines and some lesser lines to the west, Bergen op Zoom could not be completely invested, or surrounded. Further, because of the low-lying ground, large areas fronting the defenses were inundated by the Dutch using various sluices and channels and this prevented any French approach in those parts of the field. The fortress was the chief work of the great Dutch engineer, Menno van Coehoorn. It was believed to be impregnabled' Espagnac, Jean-Baptiste-Joseph Damarzit de Sahuguet.

Kornwerderzand is located approximately 4 kilometers from the coast of Friesland, on a former artificial island which was created during the construction of the dam. The settlement has a population of 22 (as of January 1, 2007). It is part of the municipality of Súdwest-Fryslân. The shipping locks at Kornwerderzand, also known as the Lorentzsluizen ("Lorentz Locks"), provide access to the Wadden Sea from the IJsselmeer, and a complex of discharge sluices control the water level in the IJsselmeer.

The mountain was logged in the late 19th century. Timber was moved down-slope in ice-covered wooden sluices. Logs, lumber, and pulpwood were shipped on the narrow-gauge Sandy River and Rangeley Lakes Railroad. F-101B fighter similar to the one which crashed on Mount Abraham A McDonnell F-101B Voodoo of the 60th Fighter-Interceptor Squadron out of Otis AFB, Massachusetts, crashed onto the mountain after colliding with another F-101B during a cross-country formation flight on 14 November 1967.

The river above Castle Mill was embanked, and although the sluices survive, the mill itself burnt down in 1910, and was not rebuilt. It was described as a large fulling mill at that time, and produced woolen and worsted cloth, while weaving was carried out in the local cottages. After the fire, Sir John Humphries rebuilt most of the mill house in the 1920s, and lived at King's Mill while the work was done. He also landscaped the surrounding area.

Albert marched towards Hulst, avoiding any contact with Maurice's army and soon invested it.Duerloo p 45 Hulst, a small but strong town commanding the Waasland of Flanders, had been captured in 1591 by an Anglo-Dutch force under Maurice.Knight (1905) p 38 The garrison had built several sconces, and defences were made more complete by a system of sluices through which the country around could be laid under water. The moat had been deepened but the walls were only partially repaired.

This usually means that the polder has an excess of water, which is pumped out or drained by opening sluices at low tide. Care must be taken not to set the internal water level too low. Polder land made up of peat (former marshland) will sink in relation to its previous level, because of peat decomposing when exposed to oxygen from the air. Polders are at risk from flooding at all times, and care must be taken to protect the surrounding dikes.

Construction in prefab caissons The barrage would contain 216 turbines each generating 40 MW for the 8,640 MW total. Arrays of sluices would let the tide in and then close to force it out through the turbines after the tide has gone out some distance outside the barrage. This deliberate building of a head on the water builds pressure that makes the turbines more efficient. The barrage would contain a set of shipping locks, designed to handle the largest container vessels.

The bridge mentioned above was replaced again, probably in 1617, but, this time, entirely in masonry. The bridge was clearly of great importance as it allowed river traffic to pass without hindrance, and also carried road traffic between the town and the Bedfordshire villages across the river. Other improvements in the same period included sluices downstream towards St Ives and works to make the river navigable upstream to Bedford. St Neots Manor passed from royal ownership under James I to Sir Sidney Montague.

The wall was probably originally continuous, from about 50 feet above the cut to 300 feet below it. The 11-mile network of sluices and associated wing dams and towing walls was constructed by Samuel Pannill of Green Hill in 1827. It was built for the Roanoke Navigation Company to permit the passage of poled river boats, called batteaux, through the falls of the Staunton River. and Accompanying photo It was listed on the National Register of Historic Places in 1980.

The old timber crib dam remained in place, submerged, upstream of the steel dam. A system of spillways, sluices (or launders as they are referred to in contemporary texts), and pipes brought water downhill to the stamp mills. The dam itself measures 74 ft (23 m) high at its center and extends for a length of 1,006 ft (307 m) across the river. Access to the reservoir was shared by the Atlantic and Baltic mines, which had a common board of directors.

Brogdens built part of the Northampton and Peterborough Railway, from Oundle to Peterborough.Contract RAIL 384/196 dated 11 January 1844 They also doubled the line from Oundle to Peterborough (contracted 11 Dec 1845).Minutes of the N&P; Committee of the London and Birmingham Railway RAIL 384/105 They built sluices and tidal gates at St Germans, Norfolk, one of the outlets of The Fens.Richardson(1870) p 227 In July 1850 they joined Mr McClean in a lease of the South Staffordshire line.

At the request of Prince Cuza, the government passed a law to dismantle the manorial mills that hindered the flow of Dâmbovița River. Likewise, it's passed a law according to that all mills and sluices that "throttle" waters to be dismantled, in order not to repeat the catastrophe. Historians note that work began immediately, with hundreds of prisoners taken to work from prisons around Bucharest. The river bed was cleaned and widened to 20 meters, and bridges with pylons in water were destroyed.

The facility includes a dam located upstream from the powerhouse, which is used to divert and control the water flowing to the generating station. It consists of a main sluice operated from Thunder Bay and six stop log sluices operated manually on-site. The intake structure is located on the eastern end of the dam and water flow into the aqueduct is controlled by three gated intake openings. The aqueduct has an internal diameter of , and terminates at a large surge chamber.

The first electric pumping station was erected at a new outfall for the Lawyers and Andersons districts in 1949, to be followed by several more. The Fleet Haven pumping station cost £21,793 and was completed in 1958/59, and in the same year, Dawsmere pumping station cost £33,868. Lord's Drain pumping station commenced operation in 1962. Sluices were also upgraded, with that on the Holbeach River being commissioned in 1955, and the Lutton Leam outfall sluice following in 1958/59.

The civil engineer John Smeaton looked at the problem of wintertime flooding in the 1760s, and some remedial work was carried out. Under an Act of Parliament of 1813, Commissioners were appointed, and improvements to the drainage included the first steam pumping engine. The Corporation of the Level of Hatfield Chase was established in 1862, and another pumping engine was installed. The drains ran to the north-eastern corner of the Chase, and continued to sluices at Althorpe on the River Trent.

When in 1293 Nicholas Fitz William, a child, was accused of fishing in the forbidden sluices of the abbot's new mill, his flight from the scene was used as evidence of his guilt. However, he explained that he had fled because John, the abbot's bailiff had already struck him twice with his bow, breaking the weapon in the process, and he was afraid of a further drubbing. He was able to call on Roger Hall to give evidence and escaped punishment.

ADA has assisted internal drainage boards by developing a national flood risk management assets database system. Once complete the system will create a register of watercourses, pumping stations, sluices within IDB drainage districts. The system has had to take into account specific IDB requirements whilst ensuring a format that will enable ease of data transfer to future systems and user defined updates. The system is currently in the initial data gathering phase and is anticipated to go live during July 2008.

The old lock has since been filled in after an incident when a miller opened the sluices and caused damage to the embankments. Its position is still visible (the position of the upper gates can be seen in the stonework above the present upper gates). An iron bridge above the lock was built between 1866 and 1877.Fred. S. Thacker The Thames Highway: Volume II Locks and Weirs 1920 - republished 1968 David & Charles The latest rebuild of the lock was in 1972.

There have been mills here for several centuries, for a cotton mill was destroyed by fire in 1792. A lake called Cuckney Dam, covering , provided the water to power its replacement, which ceased operation on 12 July 1844. After the machinery had been removed, the Duke of Portland turned the building into a National School.Genuki - White's Directory (1853), Entry for Cuckney, accessed 21 June 2010 The mill is now part of Cuckney Primary School, and its weir and sluices have been retained.

A more sophisticated device was the staunch or water gate, consisting of a gate (or pair of mitred gates) which could be closed and held shut by water pressure when the river was low, to float vessels over upstream shallows at times of low water. However, the whole upstream head of water had to be drained (by some auxiliary method approaching modern sluices) before a boat could pass. Accordingly, they were not used where the obstacle to be passed was a mill weir.

But a few most outstanding may be briefly mentioned. Rajendra Chola built a huge tank named Solagangam in his capital city Gangaikonda Solapuram and was described as the liquid pillar of victory. About 16 miles long, it was provided with sluices and canals for irrigating the lands in the neighbouring areas. Another very large lake of this period, which even today seems an important source of irrigation was the Viranameri near Kattumannarkoil in South Arcot district founded by Parantaka Chola.

In the late 1950s the Bala Lake Scheme was promoted to increase the available water for abstraction in the River Dee. Telford's original sluices were by-passed and the natural lake outlet was lowered. New sluice gates were constructed downstream of the confluence with the Afon Tryweryn (), which is only a short distance from the lake exit. This provided 18 million cubic metres of stored water in Bala Lake that could be controlled and used on a seasonal basis for low-flow regulation.

The museum is open to the public on the first and third Sundays and all bank holiday Mondays from April to September. As well as the pump, other exhibits include an hydraulic ram pump, hand pumps and an electrically driven borehole pump. Visitors can also see the mill pond below the sluices, the navigation pool and the former stables for the canal horses. The River Rother at Coultershaw is popular with anglers and contains large quantities of chub and barbel.

243–44, 666 Similar developments in shipping technology led to an explosion in seagoing trade. Finally, the development of dikes and drainage techniques (windmills, sluices) laid the base for new forms of agriculture (dairy farming) in the maritime provinces. These developments did not result directly in a major change in the economic structure of the Habsburg Netherlands. However, they provided a springboard for the developments that would follow the political upheaval that would become known as the Dutch RevoltIsrael, The Dutch Republic, pp.

In 1635, supported by petitions from many towns and from the counties affected, Sandys was authorised by Order in Council and Letters Patent, (in 1636),/ to improve the river Avon. Within a few years, he had made the river navigable at least to Stratford upon Avon, and possibly beyond. This was done by constructing 'sluices', which seem to have been pound locks (not flash locks − as often supposed). The navigation was complete to Stratford by 1640, but its cost had stretched his resources.

The landlocked Sagaing was an agrarian state. It possessed the largest granary, Mu valley, of the Irrawaddy valley that covered 93,000 hectares of irrigated lands at its peak in the late Pagan period.(Aung-Thwin and Aung-Thwin 2012: 95): In the late Pagan period, the Mu valley had three major canals, totaling about 145 km, 86 auxiliary canals, 46 weirs, 31 reservoirs, and 73 sluices, altogether numbering about 232 irrigation works. However, the agriculture during the Sagaing period never reached its potential.

The canal starts close to the Scheldt river, at the port of Antwerp, and generally runs north. After it passes the Dutch-Belgian border, it serves as the border between the Dutch provinces of North Brabant and Zeeland. Just north of the international border ships have to pass the to enter the lower part of the canal. Just north of the sluices the canal enters the artificial and leaves this lake again as a canalised section of the former Eendracht strait, before terminating in the Volkerak estuary.

Martello towers are fortifications that were built by the British Army for coastal defence during the early nineteenth century and the Napoleonic Wars. Seventy-four towers were built along the south coast; Tower 1 was at Folkestone, overlooking the harbour, and Tower 74 guarded the beach at Seaford in East Sussex. Six were built in pairs in Dymchurch to protect the Romney Marsh sluices from potential invading French forces. One of these, Martello Tower No. 24 is closest to its original condition, and has its cannon.

Their actions probably included destroying the new Maud Foster sluice. The Adventurers petitioned the House of Lords, but were unsuccessful in the House of Commons, where they were opposed by the Commoners. The House of Commons ruled that the Justices of the Peace should prevent and suppress riots, but did not take sides with either party. Legal action followed, which the Commoners won, with the result that the Court of Sewers were again responsible for drainage matters, but the ditches and sluices remained ruined for many year.

Soon after the Second World War, plans for a pumping station at Hobhole sluice, to replace the gravity outfall, were approved, and the station was fully commissioned in 1957. The disastrous North Sea flood of 1953, which affected so much of the East Coast of England had little effect in the Fourth District. In 1956, work started on a new outfall for the Hobhole drain, to the south-east of the old sluices. A pumping station containing three Allen diesel engines was built, each driving a pump.

In 1949 the town hall of Vlissingen (1949-1964) was built, designed by Roosenburg. Architect Roosenburg, who designed the Philips head office in Eindhoven, was sometimes referred to as the house architect of KLM, Philips and Stork, and he was also the designer of numerous projects for the national government. Roosenburg was a contemporary of Willem Dudok, Jacobus Johannes Pieter Oud and Gerrit Rietveld. He was the designer of the Stevin and Lorentz drainage sluices and the customs office of the Afsluitdijk, and of the Velser Tunnel.

The 16' high by 90' long granite dam was built in 1900 and currently (2009) averages 78 cubic feet/second annual discharge. Water power was supplied to nearby businesses via water wheel from the canal starting at the waterfall's enclosed plunge pool and continuing about 200' under the Neponset St. bridge. There were also two channels located between the viaduct and the waterfall (one on each side) referred to as sluices, headraces and flumes in various maps. They were filled in sometime after 1937 (U.

He proposed two methods to achieve the drainage of the levels. The first was to straighten the river, to remove all of the obstructions, and to construct an outfall sluice, to prevent the tides entering the river. The brooks on the west level and at Ranscombe would need better embankments, and adequate sluices to allow water to drain away when required. The second method involved raising the banks on all of the meadows, and constructing a separate sewer to carry surplus water from them to the sea.

The Afsluitdijk provides a road link between the provinces of Friesland and North Holland. Since North Holland was part of Vesting Holland ("Fortress Holland"), the national redoubt of the Netherlands at the time, and control of the sluices in the Afsluitdijk was necessary for planned defensive inundations in case of a military invasion, Kornwerderzand was considered strategically important by the Dutch government. From 1931 onwards, fortifications consisting of seventeen casemates and three bunkers were constructed. The position was manned with approximately 220 troops in 1939.

It contains the Lancaster Tower, a name often given to the fort itself. Fort Nieulay, located along the Avenue Roger Salengro originally dated to the 12th or 13th century. During the English invasion in 1346, sluices gates were added as water defences and a fort was built up around it in 1525 on the principle that the people of the fort could defend the town by flooding it. In April and May 1677, Louis XIV and Vauban visited Calais and ordered a complete rebuilding of Fort Nieulay.

The diameter of the piston is . Outside, the ringvaart canal's system of sluices, mills, and bridges, are all part of the Stelling van Amsterdam, the main dike of which runs just north of Cruquius, through Vijfhuizen. Fort Vijfhuizen is used for art exhibitions and is a short walk north of the museum along the ringvaart. What is less known is that there is also a fort Cruquius, just south of the museum, that also has World Heritage status because of its link to the Stelling van Amsterdam.

The Fishbourne Reach of Chichester Harbour, Dell Quay In Roman times the harbour was navigable all the way to Fishbourne, and Roman galleys may have sailed right up to the Fishbourne Palace.Chichester Harbour Conservancy (2006) "Chichester Harbour – a Reference Guide p. 75" Sea levels in the harbour were higher in the Middle Ages than they are now, and there are records of losses of land to the sea. The Great Flood of Apuldram occurred in 1274, following which additional sea walls and sluices were installed.

The moat surrounding Matsumoto Castle A moat is a deep, broad ditch, either dry or filled with water, that is dug and surrounds a castle, fortification, building or town, historically to provide it with a preliminary line of defence. In some places moats evolved into more extensive water defences, including natural or artificial lakes, dams and sluices. In older fortifications, such as hillforts, they are usually referred to simply as ditches, although the function is similar. In later periods, moats or water defences may be largely ornamental.

Druid was fitted out as a 16-gun troopship between February and April 1798 under the command of Commander Edward Abthrorpe. On 14 May she sailed from Margate to take part in Sir Home Popham's failed attack on Ostend. The British troops landed and destroyed some sluices and locks to block gunboats and transports at Flushing from joining an invasion of Britain. However, high surf prevented the retrieval of the troops, and the landing party suffered 60 men dead and wounded, and 1134 captured.

Tughlaq's primary attention to infrastructure, particularly of iron supply to the city, was also well thought out. A structure (weir or tank) with seven sluices (Hindi:Satpula, meaning "seven bridges") was built on a stream that flowed through the city. This structure called the Satpula is still existing (though non-functional) near Khirki village on the boundary walls of Jahanpanah. Similar structures had also been built at Tughlaqabad and Delhi in Hauz Khas Complex, thus covering the water supply needs of entire population of Jahanpanah.

Reed grasses growing in the riverbed of Fish slow down the flow of water and further aggravate the danger of flooding. (Full information only in the print version) Before the dam was built, Mariental was flooded in 1923 and 1934. Floods after the commissioning of the dam occurred in 1972, 1974, 1976, 2000, and 2006. Since then, the dam's water level is kept at a maximum of 70% of its capacity to prevent both an overflow and an uncontrolled outflow through fully opened sluices.

Weirs, pools and sluices in the upper reaches have long been used as part of water management in the area and it is proposed to restore many of them to aid in future flood prevention. An eighteenth-century water mill at Willsbridge was in operation until the 1960s. Originally used for milling hoop iron, it was converted in the early nineteenth century for flour production. It has been restored and now serves as a focus for a nature reserve managed by Avon Wildlife Trust.

On 14 September, Fairfax ordered the sluices be opened and the banks of the Humber be broken, as had happened in the first siege of Hull in 1642. This flooded the surrounding land to a distance of two miles. The Parliamentary warships Lion (captained by Thomas Rainsborough) and Employment arrived to control the Humber Estuary and bring in supplies. On 22 September, Cromwell crossed the Humber from Lincolnshire with arms and ammunition for the defenders, and joined the Fairfaxes in the defence of the city.

Two 1.5 ft diameter siphons, located in front of the gates of the two outer sluices and discharging into the center sluice, are provided for maintaining the minimum pool. Other Structures: none Maximum flow of record at the dam site: (04-20-1940) Reservoir design flood peak flow: . The normal pool level of the lake is , at which a reservoir is formed.

Passing through Pont Aberglaslyn, the river emerges from the gorge into the relatively flat agricultural land of Tremadog and Porthmadog. This wide flat valleynow called Traeth Mawrwas once the estuary of the Glaslyn before the Porthmadog Cob was created. This sealed off the mouth of the estuary enabling the land to be reclaimed. Once the river has crossed under the railway line, it meanders in large pools and marshes before eventually passing through the tidal sluices on the Cob at the south-eastern end of the town of Porthmadog, and from there into Tremadog Bay.

It has been pointed out that the water of the reservoir could be trained into the ditch of the fort through two sluices gate. On the southwest corner of the fort, another small tank was dug, which is known today by its name Radhasagar. Habitation zone of the peoples is being documented towards the south and north of the fort immediately after the fortified wall. Lowe town or habitation area is further superimposed by another mud wall within 100 hectares radius at each settlement zone, the mud wall has single gate in the middle.

Two new pumping stations at Leverton and Benington were completed in 1976, again on the eastern edge and pumping directly into The Wash. The pumping station at Thorpe Culvert was managed by the Anglian Water Authority, but a replacement in 1983 was partly funded by the Fourth District. The Hobhole pumping station was modified in 1988, when the old sluice channel was reopened and the sluices were fitted with four submersible electric pumps, manufactured by Flygt. The number of electric pumps at Lade Bank was increased to three in 1990.

The drainage system consists of sewers, culverts, natural and artificial dykes and lakes which feed seven pumping stations and gravity sluices that discharge the water into the Thames and creeks. Four of the discharge sites are "high flow" stations capable of discharging 600 litres of water per second at any tide level. The levels within the system are managed by a further five "low flow" pumping stations. The Environment Agency's Thames Estuary 2100 flood defence plan includes Canvey Island as one site for alleviating the flood risks to London and the Thames estuary area.

It had a characteristic shallow-pitched slate roof, and Madocks instructed that the walls should be yellow, and the windows painted dark green. Nearby were a corn mill and a fulling mill. The water was provided by building a dam across a small valley, to form Llyn Cwm Bach, with sluices channelling the water to feed the mill and the factory. Although Madocks initially employed a Mr Fanshawe to manage the factory, he was not happy with his performance, and soon the project was being managed by John Williams, Madocks' assistant.

After the aycutdars repeatedly represented to the State government to bring the reservoir to proper use, a plan was executed to block the polluted waters of River Noyyal from entering the reservoir and allowing the LBP canal water to drain into the reservoir by constructing a check dam and work has almost been completed. But the inlet canals, reservoir bed and other sites have silted up heavily for want of proper maintenance over the past 20 years. The sluices and shutters have been damaged heavily and have fallen prey to nature's vagaries.

As far as I recall, small branches and small sluices could only be found in Zalaegerszeg or further downward on the river Zala (but not even there in all the cases: e.g. in the 1950s the Baumgartner mill in Zalaegerszeg didn’t feature a small sluice). In the riverbed hollows or incavations could form while in other tracts the water was shallow and running. During floods, everything got messed up: in the stead of the river Zala and its meadow, a spectacular, uninterrupted expanse of water appeared that a few days later receded.

Kerala state received unprecedented rains during the month of July 1924. Kerala received 3,368 mm of rain during the monsoon season (June to September), 64 per cent higher than normal and is the highest recorded rainfall. The flood was probably caused by offshore vortices along the west coast and perturbations higher up in the troposphere and is not attributed to any depression or cyclonic disturbance in the Arabian sea or the bay of Bengal. The rivers in the state were in spate and a sudden opening of the Mullaperiyar sluices caused even greater misery.

540th E&M; Company served in the Italian Campaign 1943–5. During the campaign, the re-establishment of electric power supplies was critical. Power stations in the south of the country were quickly captured intact, but north of Naples and Foggia the Germans had destroyed everything to do with electricity supply: power stations, sub-stations, hydro-electric dam sluices, transmission lines and pylons were all wrecked. Repair was a collaborative effort of the British Royal Engineers and Royal Navy with US and Italian engineers, under an Electric Power Committee set up in December 1943.

The mill pound above House Mill and Clock Mill used to extend northwards to the Lea Bridge Sluices at Lea Bridge Road, but is now very small. House Mill was acquired by the River Lea Tidal Mill Trust Ltd in 1985, and has since been refurbished and opened to the public. The mill wheels are not yet operational, and will not now be tidal, but flow through the new weir could enable them to operate again, and there are hopes that they could be used to generate hydroelectricity.

This left the lock in good condition, but not operational, since the gates did not have balance beams, and the hydraulic operating mechanism was not included in the work. Funding for the provision of the equipment came from the development of the area for the 2012 Olympic Games. Another £200,000 wes spent on the hydraulic rams, sluices, and the associated controls, and on lock ladders and landing stages to enable the lock to be used safely by boaters. The work was completed in 2010, and the lock was formally opened on 31 July.

Other emigrants followed, camped in the canyon and went to work at mining. However, when the supply of water in the canyon gave out toward the end of summer, they continued across the mountains to California. The camp had no permanent population until the winter and spring of 1852–53, when about 100 men worked part of the year along the gravel banks of the canyon with rockers, Long Toms and sluices. After nine years, the Gold Canyon placers were producing less, and many miners left for the Mono Lake placers.

This was popular in the fertile river valleys of the Tungabhadra and Kaveri. In addition, clearing of forests for cultivation was viewed favourably as it not only brought new sources of revenue but also created job opportunities for the landless and introduced forest dwellers to a more agrarian life style. Whenever land was cleared for cultivation, it was on a large scale. Knowledge of agriculture included assessing irrigation systems like tanks, reservoirs with sluices, canals and wells which were built and maintained at the expense of local villagers.

The loosened gravel and gold would then pass over sluices, with the gold settling to the bottom where it was collected. By the mid-1880s, it is estimated that 11 million ounces (340 t) of gold (worth approximately US$15 billion at December 2010 prices) had been recovered by "hydraulicking". This style of hydraulic mining later spread around the world. A byproduct of these extraction methods was that large amounts of gravel, silt, heavy metals, and other pollutants went into streams and rivers.Rawls, James J. and Orsi, Richard (eds.) (1999), pp. 32–36.

2 2003: 227–229 The next day, Toungoo forces began their final push, driving out the Mrauk-U army from Launggyet and surrounding the heavily fortified Arakanese capital. They even breached the eastern outworks of Mrauk-U but were flooded out when Min Bin opened the sluices of the city's reservoirs. Unwilling to pursue a long siege, Tabinshwehti agreed to a truce with Min Bin on 30 January. Toungoo forces began their retreat three days later, and evacuated Thandwe on 26 March 1547 (5th waxing of Late Tagu 908 ME).

The first Yuba-area miners panned for gold in stream beds in the valley, but within a decade large-scale industrial processes replaced solitary prospectors. Mining companies moved from the valley floor into the Sierra Nevada foothills, where miners blasted gravel hillsides with high-pressure jets of water—a process called hydraulic mining. After the miners extracted gold in long wooden sluices, they dumped the remaining sediment slurry back into the mountain valleys. Rivers and streams carried the flood of sediment—called slickens—down to the Sacramento Valley.

As Campion is about to drown in Savanake's mighty hands, Amanda opens the sluices of the mill-pond and flushes Savanake away. Campion is exhausted, and Savanake climbs out of the water; Amanda distracts him and grabs the box, but takes a bullet from Savanake's gun as she shuts a door on him. Savanake tries to get round to them, but falls through a rotten walkway. When Campion tries to help him, he shoots at Campion, losing his grip as he does so, and is washed into the waterwheel and killed.

The Vechte's riverine landscape and the canals with their rows of trees are a popular place for a walk, and to enjoy the idyll. The canals, built more than 100 years ago for transport and draining the moorlands, now form part of a faunal habitat with many species and are now used for leisure and recreation. Sluices made out of sandstone and clinker, some still worked by hand, separate different water levels and are popular destinations for nature lovers. Fields and meadows frame farmlands on the town's outskirts.

In 1517 the dam was not yet ready and Haarlem sent soldiers to destroy the work underway. Again the Hof van Holland needed to mediate the heated tempers and again the decision was in favor of the Heemraden. Haarlem was allowed its own sluice gate for small ships, the Klein Haarlemmersluis, which kept working until 1897, when a new sluice was built. To manage the finances of building and maintaining the dam and all its sluices, it was decided to split the costs (and toll income) among the water boards downstream.

The road at the southern aspect faces onto farmland and the River Great Ouse. The river levels are regulated by a system of locks and sluices, and after heavy rains the river is allowed to flood across the large area of meadows on Holywell Front to a depth of several feet, often covering the road. Access to the houses, which are all in an elevated position on a gravel bank running roughly east–west, is via a footpath or access track from the northern side of the village.

The building of the Mound causeway, designed by Thomas Telford and built between 1814 and 1818 to carry what is now the A9 road, reduced the size of the loch. The causeway, which is nearly 1 km long, acts as a tidal barrier, stopping the sea some 2.5 km short of the former tidal limit. Sluices in the causeway allow salmon and sea-trout to continue to migrate upstream to spawning areas, as well providing an outflow for the River Fleet.The Story of Loch Fleet National Nature Reserve. p. 7.

Perry was succeeded by John Grundy, Sr., who had arrived in the region in 1731 at the request of the Duke of Buccleuch, who wanted his estates surveyed. Perry was building the Spalding sluice at the time, and Grundy's work allowed him to study drains, banks, sluices and outfalls. He formed the opinion that mathematical and philosophical principles should be applied to the drainage of low-lying regions. In 1733, he surveyed the parish of Moulton, a little further downstream, to assess how drainage could be improved for the Commissioners of Sewers.

A 1946 act provided for re-closing the Channel with dams and sluices at Thyborøn, but this was never carried out. This idea re-emerged in 2005 and is now officially being investigated. It is thought that the isthmuses would be easier to preserve, and that the water level of the Limfjord would be more controllable. In periods of persistent western winds, flooding occurs on low-lying land and harbour areas in the towns of the western Limfjord, since the water can't escape through the narrow, eastern part of the Limfjord.

The tower was built to provide water pressure to power the hydraulic machinery (for cranes, lock gates and sluices) at the Grimsby Docks. The tower was built to carry a tank above the ground with a direct feed into the machinery. Small pumps topped up the tank as the hydraulic machinery drew off water. The tower system was brought into use in 1852 working the machinery of the lock gates, dry-docks and fifteen quayside cranes, and also to supply fresh water to ships and the dwelling houses on the dock premises.

The pipes were set up downhill, to increase momentum and pressure so water could be pumped out at high velocities to erode sediment from the hillside. The discharge of the monitors was so powerful they could move rocks the size of a car. The large amounts of rock, minerals, and soil from the hillsides were then directed into sluices where miners would sift through the sediment to remove valuable rocks or minerals. However, the process yield relatively little profit in comparison to the massive amounts of debris generated.

Thus the beds of the sluices across the canal lie almost on the water surface of the canal. The works allowed the river path nearest an approaching boat to be stopped for a period of time to allow a canal boat to cross through that area and rest for a time in the "protected area" between the two paths. The river path behind the boat would now be returned to flow and the path in front of the boat is halted. The boat can now cross this second path without interference.

The lake forms part of the River Dee regulation system and the level at its outflow is automatically controlled. Depending on flow conditions and the level of water in Llyn Celyn, water can flow either into or out of the lake at the normal outflow point. Controls on the level of water in the lake were first constructed around 1840. Sluices designed and built by Thomas Telford and William Jessop were installed to ensure that the newly constructed Ellesmere Canal had a constant and sufficient supply of water.

Until recently, some northern European communities held well dressing ceremonies to appease the snake-spirits which lived in village wells and told legends of saints defeating malevolent lake-snakes e.g. Saint George killing a maiden-devouring serpent or Saint Columba lecturing the Loch Ness Monster which then stopped eating humans and became shy of human visitors. Carved stones depicting a seven-headed cobra are commonly found near the sluices of the ancient irrigation tanks in Sri Lanka; these are believed to have been placed as guardians of the water.

A series of published exchanges took place in early 1736. Grundy took the view that making channels narrow and deep was important, since it increased the speed at which the water moved, and therefore its scouring action. Baseslade advocated allowing the maximum volume of water to move up and down a tidal river, and therefore opposed sluices, new cuts and the enclosing of salt marshes. Although the debate continued long after Grundy's death, he again pioneered the use of scientific principles, using works such as Castelli's Mensuration of Running Water to support his case.

Operation Veritable: A dirty slogging-match in the mud of the Rhineland, by William Moore (p. 3). The next day the Germans released water from the largest Roer dam, sending water surging down the valley, and irreparably jammed the sluices to ensure a steady flow for many days. The next day they added to the flooding by doing the same to dams further upstream on the Roer and the Urft. The river rose at two feet an hour and the valley downstream to the Maas stayed flooded for about two weeks.

This provides an additional of storage capacity. and its operation results in progressive flooding of the Meadowgate Lake, the Nethermoor Lake and the main lakes. Levels within the park were carefully designed to allow it to flood in this way, and there are a number of sluices and flap gates so that stored water can be released back to the river in a controlled fashion. The regulator is of a different design to the other two, as the gate is located on the bed of the river, and rotates upwards as required.

Much of the site is now occupied by Crane Park, in which the old Shot Tower, mill sluices and blast embankments can still be seen. Much of the area along the river next to the Shot Tower is now a nature reserve. The 1818 Enclosure Award led to the development of of land to the west of the town centre largely between the present day Staines and Hampton Roads, where new roads – Workhouse Road, Middle Road, 3rd, 2nd and 1st Common Roads (now First to Fifth Cross Roads respectively) – were laid out.

It flows generally northwards and through the towns of Moncontour and Brézé, finally flowing into the Thouet in Saint-Just- sur-Dive. In common with most rivers in this region of France flows are quite widely controlled by creation of heads of water, through embankment and barrages, which prevents near loss of upper reaches in summer. For winter sluices are opened, which prevents flooding, which historically would affect a small proportion of the land as the river gradient is relatively high and the valley modest but noticeable along most banks.

At the base of the gates there is a high level weir at 16.0mGD level in contrast to the 14.0mGD invert channel depth. This feature, along with the enormous size, discharge capacity, advanced motorized winches and control systems are what makes this structure different from the common sluices. The High Level Sluice is the largest sluice in Guyana. The construction of this structure was undertaken by Courtney Benn Contracting Services Ltd (CBCSL) Construction started on August 8, 2011 and was concluded on December 15, 2013 Total Cost of this Project was G$605,430,630.

Water is drawn from the north side of the Thames about 300 yards above Bell Weir, at a decorative sluice house. This is provided with sluices to control the flow and screens to prevent debris entering the aqueduct. The water runs underground for about 350 yards in a north-east direction, it then flows in two steel siphons under the Colne Brook. It continues in a concrete lined open conduit, before going under the Wraysbury river in steel siphons, then east across Staines Moor and another siphon under the River Colne to Staines pumping station.

The extremely high pressure stream was used to wash entire hillsides through enormous sluices. By the early 1860s, while hydraulic mining was at its height, small-scale placer mining had largely exhausted the rich surface placers, and the mining industry turned to hard rock (called quartz mining in California) or hydraulic mining, which required larger organizations and much more capital. By the mid-1880s, it is estimated that 11 million ounces of gold (worth approximately US$7.5 billion at mid-2006 prices) had been recovered by hydraulic mining in the California Gold Rush.

Weaver Sluices on the Manchester Ship Canal discharge water from the Weaver into the Mersey. Below Frodsham, barges carrying salt had to negotiate a tidal section of the river to reach the Mersey, from where the cargo would be taken to Liverpool or Manchester for distribution worldwide. Water levels were inadequate for the Mersey Flats at neap tides, resulting in them having to wait for days at Frodsham. In 1796, users of the navigation suggested that it should be extended to Weston Point, where the water was deeper.

Improvements to the drainage channels brought the cost up to £839,000, although 70% of this was provided by grants. In the 1980s, a £1 million scheme resulted in further improvements to the drainage works, and two more pumping stations were built, at Crabley and Skelfleet Cloughs. When the Weighton Lock sluices were converted to electro-mechanical operation in 1971, water levels in the canal could be raised without adversely affecting the drainage functions. Around 80% of the water entering the catchment leaves it via the Weighton Lock sluice.

In practice some adjustment of Bala sluices may take place to increase storage in Llyn Celyn and conversely some releases may be made from Llyn Celyn for recreational or power generation purposes. When the flow at Manley Hall decreases towards 10 m³/s, additional flow is released from Llyn Tegid. If that is insufficient, flow from Llyn Celyn is used to maintain 10 m³/s at Manley Hall. In extreme situations where the flow from Llyn Celyn is insufficient to maintain the flow, releases of water from Llyn Brenig are made.

In 1545, Tabinshwehti agreed to aid Min Aung Hla, the former Viceroy of Thandwe, who had been removed from office by Min Bin. In October 1545, Tabinshwehti sent a 4000-strong army but it was promptly driven back. A much larger naval and land forces (combined 19,000 troops) of Taungoo tried again in the following dry season. The invasion forces overran southern Arakan, and were about to breach the defenses of the capital of Mrauk U when Mrauk U forces opened the sluices of the city's reservoirs, flooding the invaders out.

On 8 June 2007 a new facility was opened for testing prototype marine current turbines and other turbine devices. This facility is operated and funded by the National Renewable Energy Centre. It uses the hydraulic head in the barge lock to release water through sluices at a controlled velocity to create a simulation of steady ocean current conditions downstream of the lock. The first turbine to be tested at this site was Evopod, a semi submerged floating tidal turbine developed by offshore consultancy Ocean Flow Energy Ltd based in North Shields.

Under the Peace of Utrecht, France agreed to 'level the fortifications of Dunkirk, block up the port and demolish the sluices that scour the harbour, (which) shall never be reconstructed.' Dunkirk was a major privateer base for raiding British merchantmen, since it was possible to reach the North Sea in a single tide and escape British patrols in the Channel. This made it a high profile operation of great significance to the powerful London mercantile interest and in September 1713, Lascelles and Armstrong were appointed to supervise operations.

Later that day, she ran lightly aground on an uncharted sandbank, but was at that time out of range of German guns and was able to free herself with help from at high tide. By the end of the month, the flooding from the opened sluices around Nieuwpoort had blocked the German advance, diverting German attacks further inland, out of range of Venerables guns. The German guns along the coast had by this time been hidden, which made it far more difficult to engage them with naval gunfire, so Venerable was recalled.

For the regrade, the streets were lined with concrete walls that formed narrow alleyways between the walls and the buildings on both sides of the street, with a wide "alley" where the street was. The naturally steep hillsides were used and, through a series of sluices, material was washed into the wide "alleys," raising the streets to the desired new level, generally higher than before, in some places nearly . At first, pedestrians climbed ladders to go between street level and the sidewalks in front of the building entrances. Brick archways were constructed next to the road surface, above the submerged sidewalks.

Aerial view of the Canal through Zuid-Beveland Railroad bridge over the Canal through Zuid-Beveland The Canal through Zuid-Beveland (Dutch: Kanaal door Zuid-Beveland) in the southwest Netherlands is the westernmost of two canals crossing the Zuid-Beveland peninsula. It connects the Western Scheldt (to the south of the canal) and the Eastern Scheldt (to the north). It is crossed by a railroad bridge (between the railroad stations Kapelle-Biezelinge on the west and Kruiningen-Yerseke on the east), a road tunnel (the Vlake Tunnel) and two road bridges. Additionally, the canal has sluices that can carry road traffic.

At this point where the Hollands Diep splits, there is a road traffic node on an artificial island (the Hellegatsplein), connecting to the Hoeksche Waard island on the north by the Haringvliet bridge, to the Goeree-Overflakkee on the west by the Hellegatsdam, and to the mainland on the southeast by the Volkerak Sluices. On the east side of the Hollands Diep the Moerdijk bridges connect the Dordrecht island on the north to the mainland on the south: a road bridge, a railroad bridge; a second railroad bridge has recently been constructed for the HSL-Zuid.

Bridge across the southern canal near the Badenburg Former sluice basin of the southern canal between the Village and the Amalienburg The canals of the palace park belong to the Nymphenburg Canal, which widely traverses large swaths of Munich's West. While the Central canal is reminiscent of French gardens, the entire system is based on Dutch models, in particular on Het Loo Palace. Most canals were navigable by boat until 1846. Remnants of the 18th century locks and sluices are located at the flooding canal behind the Great Cascade and between the Village and Amalienburg in the southern park canal.

One possible solution was to dig a new channel through the bar, near the position of the original outlet. The Prior of Lewes and some gentlemen of the area sought help from two Dutch drainage engineers and the engineer who had succeeded in reclaiming St Katherine's Marsh near the Tower of London. In 1537, they levied a scot tax on all those who had lands which were likely to flood, and the work on the new channel was completed, probably by 1539. The following year, a number of sluices along the Ouse were replaced, after they had been damaged maliciously.

The grain was bagged up for the millstones, the straw taken to the straw barn. A gathering or mill pond, leats and sluices were needed.Keys to the Past Retrieved : 2012-06-22 The water supply came from the hill above and remains of the control sluice are still visible, with an overflow running through a pipe to the Montfode Burn and the 'spent' water from the mill leaving via a substantial stone lined outflow that exited below the main farm buildings. A turbine may have been used as no signs of a waterwheel and associated equipment exist.

Excavated material was used to backfill the old river channels, so that loss of land was reduced. To protect the surrounding low-lying land from flooding by the river, the channel was embanked. The embankments were designed with self-acting sluices, to allow tributaries to pass through them when water levels were suitable. After some of the embankments had been finished, local landowners petitioned against their completion, as they felt that the lower level of Lough Neagh and the works already carried out gave them sufficient protection, and it was inadvisable to completely protect the land.

Interior Bin The present Carew Tidal Mill has two water wheels, one with the date of 1801, so was probably built around that time. The floodgates in the causeway dam were opened as the tide rose and filled the mill pond, then closed to contain the water in the pool when the tide began to ebb. When there was enough difference between the water levels the miller opened the sluice gates so the water would run from the pond through sluices under the mill, driving the water wheels. There are two undershot water wheels with wooden bucket paddles.

The lock is managed and owned by the Middle Level Commissioners inland drainage authority. This authority is responsible for the middle-level network of drains, primarily for land drainage in the area, but also the navigation link between the two rivers. Salters Lode lock is part of the Denver complex which makes up the main gateway onto the Great Ouse navigation system from the tidal river. The Denver complex consists of a number of locks and sluices that are used for navigation access and management of water levels on the numerous waterways that characterise this part of The Fens.

To meet efficiently, the Hoogheemraadschap bought a meeting hall in 1578, that was also the permanent residence of the Dike warden. The facade was renovated twenty years later in 1598 to keep up with the new town hall. This Gemeenlandshuis is the first one used by the Hoogheemraadschap van Rijnland, but to meet with the Amsterdam Water Board and inspect the dikes along the Haarlemmertrekvaart and the sluices at Halfweg, the Gemeenlandshuis Zwanenburg was built by Pieter Post in 1645-1648. Though nearly demolished today, there is a town named after this building in the Haarlemmermeerpolder called Zwanenburg.

River Algibre () is a small river in the Portuguese region of the Algarve. The Algibre River is formed by the confluence of the Mercês (Ribeira das Mercês) and Benémola (Ribeira da Benémola) rivers close to the village of Querença in a small fertile valley. The area is characterized by many derelict sluices and dams that date back to the period of Arab occupation, during which the whole area was irrigated and agriculture was the predominating activity of this land. The river along with the Alte River, another tributary, becomes the River Quarteira after the two rivers conflux.

V. 1968–1993, Heimatverein Schlußdorf (ed.), Ritterhude: Diem \+ Neumann, 1993, p. 27, after NN, „Museumswerft wird eingeweiht: Heimatverein Schlußdorf gibt Gebäude zur Besichtigung frei“, in: Wümme-Zeitung, 16 August 1977, page unknown. Once crisscrossed by drainage trenches, hill moors – like the Teufelsmoor – do not well hold water, thus, in order to maintain a navigable water level manually openable sluices (N. Low Saxon: Schütt[en]) were installed every to in all the watercourses.Johannes Rehder-Plümpe, „Die Struktur der Findorff-Siedlungen“, in: Die Findorff-Siedlungen im Teufelsmoor bei Worpswede: Ein Heimatbuch, Wolfgang Konukiewitz and Dieter Weiser (eds.), 2nd, revis. ed.

It is backed with steps of granite blocks, each to the height of a course (2 feet). The stone and sand for the concrete was sourced locally, the stone was quarried from a hill two miles (3.2 km) to the north and the sand was obtained from various pits within four miles (6.4 km) of the weir. The granite for the weir was sourced from Mount Black, 15 miles (24 km) to the south west. The weir was completed, the tunnel sluices closed down and the river allowed to flow over the weir in the early part of December 1890.

The sides of Carnsew Pool are built of rubble and slag, and New Pier was also built, to direct water through sluices, into the estuary; thus flushing silt out of the river channel adjacent to Harvey's foundry. The complex system maintained the port facilies which allowed the two competing foundries to increase their national and international roles. As well as building steam engines, Harvey's developed their business with overseas exports, shipbuilding and ship-breaking. Harvey's fleet of 79 ships built at Hayle including the 4000 ton SS Ramleh in 1891; the largest ship to be built in Cornwall.

The French commandant, Major Huck, simply told the Germans to go back and the French began shooting at the Germans from the houses and gardens nearby. The German cavalry broke their way out and destroyed the sluices controlling the water in the ditches. Another demand for surrender came on 15 August, this time from Captain von Rosen of the 2nd squadron, 3rd Lancers of the Guard, whose men had advanced on the fortress under fire, though they suffered no losses. The commandant turned down the demand as before, and the Germans returned to Ménil-la-Tour in the afternoon.

This diversion project transports water under the continental divide from Navajo Lake to Lake Heron on the Rio Chama, a tributary of the Rio Grande. In the past much of this water was resold to downstream owners in Texas. These arrangements ended in 2008 with the completion of the ABCWUA's Drinking Water Supply Project.The project's page at the United States Bureau of Reclamation's website The ABCWUA's Drinking Water Supply Project uses a system of adjustable-height dams to skim water from the Rio Grande into sluices that lead to water treatment facilities for direct conversion to potable water.

Grundy used a number of devices to enable him to carry out surveys, including a theodolite, a circumferentor, Beighton's improved plane table, and a Gunter's chain. When he undertook work for the Duke of Baccleugh in 1731, surveying his south Lincolnshire estates, he used the opportunity to study banks, drains, sluices and outfalls. The contract lasted for six months, and it was during this time that his ideas about applying mathematical principles developed. In 1733, he worked for the Commissioners of Sewers, surveying the parish of Moulton, near Spalding, and suggesting ways in which its drainage could be improved.

On June 1, 1893, the glory days of the company began to come to an end when the county Circuit Court issued a writ of attachment against it. In the following days, other parties were granted writs totaling $4,420 in unpaid wages and $6,000 in other debts. An injunction was issued against the sale of the property or company stock by the ownership, and the county sheriff was ordered to guard the property until the cases could be resolved. Sheriff Dillard decided that it was better to clean out the gravel in the sluices rather than guard the property around the clock.

Higher Hurdsfield is a civil parish in Cheshire East, England. It contains 13 buildings that are recorded in the National Heritage List for England as designated listed buildings, all of which are at Grade II. This grade is the lowest of the three gradings given to listed buildings and is applied to "buildings of national importance and special interest". The parish lies to the east of the town of Macclesfield, and is mainly rural. The Macclesfield Canal runs along is west border, and there are four listed structures associated with it, two bridges, a milestone, and a culvert with a weir and sluices.

Typical Fenland windpump typical Fenland sluice As the drainage succeeded in its general purpose, albeit with many technical difficulties, the level of the land sank as it dried out, negating the achievement. It then became necessary to introduce windpumps (hundreds in all) to lift the water from the fields into the drainage ditches and rivers. The windpumps had to be replaced over time with more efficient steam-powered and then diesel-powered pumps. The system also depended on a number of sluices (locks) to prevent flooding at high tide or to control the flow of water within the system.

The River Brue originates in the parish of Brewham in Somerset, England, and reaches the sea some west at Burnham-on-Sea. It originally took a different route from Glastonbury to the sea, but this was changed by Glastonbury Abbey in the twelfth century. The river provides an important drainage route for water from a low-lying area which is prone to flooding which man has tried to manage through rhynes, canals, artificial rivers and sluices for centuries. The Brue Valley Living Landscape is an ecological conservation project based on the Somerset Levels and Moors and managed by the Somerset Wildlife Trust.

Dymchurch Martello Tower is a Martello tower in Dymchurch, Kent England. It stands immediately behind the sea wall. It has been designated by English Heritage as a scheduled monument and a Grade II listed building.. The towers, ranging along the Kent and East Sussex shoreline, were built in the early years of the nineteenth century as part of a coastal defence programme against a threatened French invasion under Napoleon. The 24th of 75 such towers, it was placed to protect the gates of marsh sluices with its counterpart Tower no 25 (which is now largely derelict).

An old Portuguese pilot suggested that they go to Ningpo by the mouth of a river. This Ningpo was a canal that passed through the heart of that vast empire of China, crossed all the rivers and some hills by the help of sluices and gates, and went up to Peking, being near 270 leagues long. So they did, then it was the beginning of February, in the Old Style calendar, when they set out from Peking. Then they travelled through the following places: Changu, Naum (or Naun, a fortified city), Argun(a) on the Chinese- Russian border (13 April 1703).

General View of Kala Wewa Kala Wewa, built by the King Datusena in 460 A.D, is a twin reservoir complex (Kala Wewa & Balalu Wewa) which has a capacity of 123 million cubic meters. This reservoir complex has facilitated with a stone made spillway and three main sluices. From the central major sluice, a 40 feet wide central conveys water to feed thousands of acres of paddy lands and ends at the historical capital Anuradhapura city tank Tissa Wewa meandering over at a slope of 6 inches per mile and is another wonder of primeval hydraulic engineering facility in ancient Ceylon.

Although Vermeuden had been successful in carrying out similar works in the Low Countries, there were issues with those on Hatfield Chase, and remedial action was taken over the next few years. The onset of the English Civil War created confusion, and enabled locals to sabotage the works, re-flooding parts of the Chase by raising flood gates and breaking down banks and sluices. Riots broke out in 1650, and there was general unrest until matters were resolved in 1719. Efforts to improve the drainage of the area were made in the 18th, 19th and 20th centuries.

Sluice outlet from the dam The ancient and solid gravity dam structure, a pre-Islamic structure that fords a local nala (stream) is in height and in length between the two banks. It has been built with quartzite stones (locally available), duly chiselled and dressed, as a regular dam section with downstream base width increasing in steps with depth up to the foundation. It has entry manholes from the top of the dam, which lead into the body of the dam for inspection and control of flow through sluices for downstream uses. The intake entry into the sluice is on the upstream side.

Care is taken to maintain the water levels on each side, thus balancing the weight on each arm. According to Archimedes' principle, floating objects displace their own weight in water, so when the boat enters, the amount of water leaving the caisson weighs exactly the same as the boat. This is achieved by maintaining the water levels on each side to within a difference of using a site-wide computer control system comprising water level sensors, automated sluices and pumps. It takes to power ten hydraulic motors, which consume per half-turn, roughly the same as boiling eight kettles of water.

The dam is built on a shattered rock based with a central masonry spillway. It has an earthen embankment on the left side and a rock hillock on the opposite side. The Ogee type spillway in the middle section of the river has been provided with four numbers of vertical lift gates over a width of and designed for a discharge of /s. In addition, two number river sluices are also provided to pass a discharge of /s. The annual siltation load considered in the design is 10.78 million cubic feet per square kilometer of catchment area.

Later they were extended, with Hill Top and Rishton mills expanding up the embankment to access to the towpath. By the turn of the 20th century, twelve mills were operating alongside the embankment—all but two of which supported the town's textiles industry. Their location was likely influenced by the decision the canal proprietors took in the 1840s to allow water to be taken from the canal to power the mill engines. The embankment, carrying the canal above the mills, provided a suitable head of water for the mill owners and sluices were built to control abstraction.

This section counts as a confined space, and was surveyed in 2007, in a joint venture between the Environment Agency, a team of divers, and Bassetlaw District Council. Some five tons of debris, half a ton of steel, and some stolen goods were removed from the culvert during the exercise. Beyond Watson Road bridge, sluices and extra channels point to the existence of the mill near the Priory. Priory Water Mill was in use from the medieval period until 1876, and a large lake called the Canch was formed in 1820, by constructing a dam across the leat which fed it.

The Fens were drained beginning in 1626 using a network of canals designed by Dutch experts. Many Fenlanders were opposed to the draining as it deprived some of them of their traditional livelihood, Acts of vandalism on dykes, ditches, and sluices were common, but the draining was complete by the end of the century. The area's natural defences led to it playing a role in the military history of England. Following the Norman Conquest, the Isle became a refuge for Anglo-Saxon forces under Earl Morcar, Bishop Aethelwine of Durham and Hereward the Wake in 1071.

Sign and part of the Deutsche Fährstraße at river Elbe close to the ferry Glückstadt - Wischhafen The Deutsche Fährstraße (German Ferry Street), established in May 2004, is a theme route similar to the American National Scenic Byways. It connects various places between Bremervörde and Kiel with relation to the history of ferries and crossing of rivers, like the historic transporter bridges in Rendsburg and Osten. It is 250 km long and connects 50 bridges, sluices, barrages and ferries and demonstrates all variations of methods crossing water. It contains parts of the rivers Oste, Elbe, the Kiel Canal and the Bay of Kiel.

To overcome this problem, a series of reservoirs have been constructed to store the excess water available in the winter time and release it back into the River Dee during the drier months. This is the principle of low-flow regulation. This was used by Thomas Telford at the beginning of the nineteenth century in order to guarantee a supply of water to the Ellesmere Canal. Telford constructed sluices at the outlet of Bala Lake to control the flow downstream so that there was always sufficient water to supply the canal where it started at Horseshoe Falls.

He made it perfectly clear that this could never be the case as long as French troops were still fighting the Germans. Late in the evening, a radio transmission was broadcast stating that Dutch forces in Walcheren and Zuid-Beveland would surrender. Half an hour later, Lieutenant-Colonel Karel himself went to the road east of Middelburg along which German troops were heading southward. He was transported to a hotel near Vlissingen, close to the sluices, where he officially informed SS-Standartenführer Steiner—commander of the SS Regiment—of the capitulation of the Dutch forces on Walcheren and Zuid- Beveland.

An avenue led southwards from the house to two lakes, named the Quobleigh Ponds, the water levels in each being controlled by separate sluices. Within the parkland were eight fenced areas containing two or three conifers each, and the estate's fields were bounded by trees. Twenty years on many of the trees had been felled and a walled garden created to the west of the house, accompanied by four glasshouses. A turning circle had been added to the driveway in front of the house, and additional buildings around the Quobliegh Ponds: a boathouse on the northern side and a hide to the southeast.

In 1931, a plan was proposed to develop the island and the waters between it and the coast. Called the "Blue Lagoon Scheme," this would have included dams and sluices at the Wooden Bridge and Sutton Channel, maintaining a high water level behind the island, which itself might hold some housing or tourism facilities. Further plans were advanced by Bord Failte, including conversion of much of the island as a theme park. In 1931 Dublin Corporation was convinced by campaigners like the Jesuit ornithologist Fr. Patrick G. Kennedy SJ (1881–1966),Bull Island - Irish Sanctuary www.manrsea.

It ran from Gold Corner, where it was connected to the South Drain, to a new outfall on the estuary of the River Parrett, and had retention sluices at both ends, so that it acted as a long reservoir. It was intended that in the summer, when water supply was lower, it would serve as a reservoir with water pumped from the moors; in winter as a drainage channel, via gravity drainage. The plans were for a channel, with the excavated earth used to create flood banks at its edges. At this depth, water could flow into it from the moors by gravity, but problems were experienced with the design.

They were ordered to place mines in four areas: the Pennsylvania Railroad in Newark, New Jersey; canal sluices in both St. Louis, Missouri, and Cincinnati, Ohio; and New York City's water supply pipes. The team members made their way to Cincinnati and then split up, two going to Chicago, Illinois, and the others to New York. Dasch's confession led to the arrest of all of the men by July 10. Because the German agents were captured in civilian clothes (though they had landed in uniforms), they were tried by a military tribunal in Washington D.C., with six of them sentenced to death for spying.

Mylchreest) was of the opinion that the Fenella would float on the tide and that she would swing to her anchor, and they "had steam" which effectively meant that the ship could use her own power. He cited that the ship was watertight and that he was certain no water would enter the ship. Capt. Mylchreest stated his bulkheads were strong and that his watertight doors (sluices) were all lowered. Capt. Thomas then stated that the straights were narrow, and there was a high risk of the Fenella dragging her anchor, and he could lend assistance to help turning the Fenella's head around as she swung on her anchor. Capt.

That it has been used as a feeder channel for a water meadow system is beyond question. The telltale surface patterns of water meadows can still be made out in places from the path along the Canal, and are even clearer from Google Earth images. Further, the remains of a couple of the sluices through which water was admitted from the Canal to the water meadows can still be seen, and 19th century 1:2500 maps show a dozen more. What is less clear is when the New River was built and by whom, and whether it was ever used as a navigation channel.

As well as preventing the ingress of sea water, the banks also prevented fresh water from the land reaching the Humber, and so a network of channels were cut, to channel water to the Hull and the Humber. Primitive sluices were built where the channels passed through the banks, to ensure that water only passed in one direction. The carrs to the north remained flooded, although a number of channels were cut through them by the monks from Meaux Abbey. These ran in an east-west direction and were primarily to aid transport by boat, rather than for drainage, although their large size tended to have some effect on the land.

To provide Dadu with a new supply of water, Guo had a 30 km channel built to bring water from the Baifu spring in the Shenshan Mountain to Dadu, which required connecting the water supply across different river basins, canals with sluices to control the water level. The Grand Canal, which linked the river systems of the Yangtze, the Huai, and the Huang since the early 7th century, was repaired and extended to Dadu in 1292–93 with the use of corvée (unpaid labor)."China", 71727. After the success of this project, Kublai Khan sent Guo off to manage similar projects in other parts of the empire.

The road master (Latin: viarius) was a middle- to high-ranking urban official common across the central and northern regions of Italy between c. 1250-1550, that is the communal and despotic era. Often part of the podestà’s or capitano del popolo’s entourage, the road master worked in small teams of builders and administrators to maintain a city's network of roads and waterways, including nodal points such as gates, bridges, sluices and markets. In many towns and cities across the peninsula, roads officials not only built and maintained such amenities, but they also monitored human and animal behavior that impacted their traversability, and fined pertinent offenders.

The British colonial administrators were the first to attempt to drain the marshes, motivated by their role as a breeding ground for mosquitoes and lack of apparent economic value, as well as the potential use of the water for irrigation. Prepared in 1951, The Haigh Report outlined a series of sluices, embankments and canals on the lower ends of the Tigris and Euphrates that would drain water for agriculture. These notably included the Main Outfall Drain (MOD), a large canal also referred to as the Third River, and the Nasiriyah Drainage Pump Station. Neither were completed under British rule: they were later revived by the Ba'athist government.

Edward Thomas' memorial stone on a hillside near Steep By the 1830s the British Agricultural Revolution had disturbed traditional society and created a class of labourers who struggled to support their families in rural areas. This led to an unrest known as the Swing riots which swept across southern England, consequently reaching Selborne and Liphook in September 1830. The Parliamentary Enclosure Acts of 1856 established a new land pattern for nearby Steep Marsh and Stroud, which still exists today. There was also extensive land drainage between 1860 and 1880; conduits and sluices were constructed to take water from Ashford Stream for the artificial flooding of hay meadows.

Among his first jobs was that of Driver on upstate New York's Chenango Canal which ran through Madison County at that time and would have been a busy thoroughfare. At the age of 19, Armour left New York with about 30 other people for California, joining the great California gold rush. Before the journey, Armour "had received several hundred dollars from his parents," making him, for the most part, "the financier of the party," according to biographer Edward N. Wentworth. In California, Armour eventually started his own business, employing out-of-work miners to construct sluices, which controlled the waters that flowed through the mined rivers.

The scheme included a number of new bridges, with the main ones being at Crandon, Bawdrip, Parchey and Greylake. Penning sluices were fitted to the bridges at Bawdrip and Greylake, to allow the water to be used for irrigation, but in many cases, the bridge openings were too small, with the result that water stacked up behind them in flood conditions. In addition to the main channel, which increased in width from as it approached Dunball, the "Eighteen Feet Rhyne" was built to drain the moor to the north of Henley Corner, and rhynes at Aller, Chedzoy, Shapwick and Street were also wide. Other rhynes were wide.

Hobson Lake is named for John B. Hobson, a man who did more than any other in British Columbia to demonstrate the value of hydraulic placer mining. With this technique, a bank of gold-bearing gravel was washed into sluices by a powerful jet of water where the gold separated from the gravel. Hobson was born in Ireland in 1844, moved to New York, and studied mining engineering and metallurgy in California. He came to Canada in 1892 at the invitation of the directors of the Canadian Pacific Railway to explore the extensive fields of gold-bearing gravel known to exist in the Cariboo District.

After the completion of the North African campaign, the Allied forces in the Mediterranean moved on to invade Sicily and then mainland Italy. During the Italian campaign the re-establishment of electric power supplies was critical. Power stations in the south of the country were quickly captured intact, but north of Naples and Foggia the Germans had destroyed everything to do with electricity supply: power stations, sub-stations, hydro-electric dam sluices, transmission lines and pylons were all wrecked. Repair was a collaborative effort of the British Royal Engineers and Royal Navy with US and Italian engineers, under an Electric Power Committee set up in December 1943.

A system of weirs, sluices, reservoirs, hydroelectric power plants, diverters and conduits, over 1000 kilometers long was planned along the canal's route. At the beginning of the canal at Takhiatash, Uzbekistan an enormous weir was built which had to be combined with the hydroelectric power plant. 25 percent of the water from the Amu Darya was to be drained into the canal to drain the Aral Sea. With the level of the Aral Sea lowered, the intention was to use the exposed land for agriculture, but the salt of the lower reaches of the Amu Darya river had to be lowered according to calculations.

The man-made Huntspill River was constructed during World War II with sluices at both ends to provide a guaranteed daily supply of of "process water". It was intended that in the summer, when water supply was lower, it would serve as a reservoir with water pumped from the moors; and in winter serve as a drainage channel, via gravity drainage. Geotechnical problems prevented it from being dug as deep as originally intended and so gravity-drainage of the moors was not possible: thus, water is pumped up into the river throughout the year. The Sowy River between the River Parrett and King's Sedgemoor Drain was completed in 1972.

The head of navigation became a new staithe at Bungay. The new section was a private navigation which was not controlled by the Yarmouth Haven and Pier Commissioners, who had responsibility for the rest of the Broadland rivers. It remained in use until 1934 and, although the upper two locks have been replaced by sluices and Geldeston lock is derelict, the Environment Agency have negotiated with local landowners to allow use by canoes and unpowered vessels which can be portaged around the locks. The next attempt was to extend navigation on the River Bure from Coltishall to Aylsham, which was authorised by an Act of Parliament on 7 April 1773.

Steam turbine While the Tone Mills site was able to use water wheels on the River Tone for power generation, Tonedale Mills initially used smaller watercourses, Westford Brook and Rockwell Green Stream. In order to ensure that they had a constant supply of water, and that it was used as efficiently as possible, Thomas Fox had water basins excavated between 1801 and 1803, establishing a series of waterways, weirs and sluices to manage the water supply. The original timber mill burned down in 1821, and was replaced by a brick mill, which remains today. The large site features a number of mills, warehouses, workshops and engine houses.

The wood waterwheel was replaced in 1934 with a metal one, and the shaft replaced by the present timber one. The waterwheel was the mill's principal source of power for about 40 years, except for a time during World War I when the government installed auxiliary stationary steam engines, and the mill was commandeered by the War Office to produce props and duck-boards for use in the battlefield trenches. In the 1950s, electric power was brought to the mill and the waterwheel became less important. When it ceased to be used in the mid-1960s, the leat was filled in and sluices buried.

Underfall Yard's former pump room - redeveloped in the 2015 project to become the visitor centre The Underfall Yard is a historic boatyard on Spike Island serving Bristol Harbour, the harbour in the city of Bristol, England. Underfall Yard was commonly referred to as "The Underfalls" and takes its name from the underfall sluices. The original construction was completed in 1809 under the direction of William Jessop and substantially improved by Isambard Kingdom Brunel in the 1830s. Restored in the 1990s, Underfall Yard has been designated as a scheduled monument and from the 1970s onward many of the buildings at Underfall Yard have earned Grade II Listed Building status.

Serving a similar function are the side ponds on lock flights such as the Foxton flight. The ten locks are organised as two staircases of five chambers each, where each lock can discharge water into the pond below it and receive water from the one above it. Although connected to the locks by sluices, they are still often called side pounds, as they are maintained at the level at which an intermediate pound would be if one were present. The term side pond is also used to refer to a water saving basin, which is maintained at a level between the upper and lower level of a single lock.

With the decline in the use of wherries for commercial trade on the rivers prior to the Second World War, navigation ceased on several stretches of the Broads, including the section of the river from Geldeston Lock to Bungay, where navigation rights were removed in 1934. Geldeston Lock (aka Shipmeadow Lock)is being restored by local volunteers of the River Waveney Trust . Wainford and Ellingham locks have since been converted into sluices, but the Environment Agency has negotiated with local landowners to allow the use of this section by canoes and unpowered craft. To aid this, it has improved the facilities for portaging boats at the locks.

Map of the Old Waterline In 1629, Prince Frederick Henry started the execution of the plan. Sluices were constructed in dikes and forts and fortified towns were created at strategic points along the line with guns covering especially the dikes that traversed the water line. The water level in the flooded areas was carefully maintained at a level deep enough to make an advance on foot precarious and shallow enough to rule out effective use of boats (other than the flat bottomed gun barges used by the Dutch defenders). Under the water level additional obstacles like ditches and trous de loup (and much later, barbed wire and land mines) were hidden.

While flowing from the sluices, coarse material is deposited first and then finer material is deposited (fine material has a slower terminal velocity thus takes longer to settle, see Stoke's Law) as the flow velocity is reduced towards the center of the dam. This fine material forms an impervious core to the dam. The water flow must be well controlled at all times, otherwise the central section may be bridged by tongues of coarse material which would facilitate seepage through the dam later. Hydraulic fill dams can be dangerous in areas of seismic activity due to the high susceptibility of the uncompacted, cohesion- less soils in them to liquefaction.

When the U.S. began negotiating the 1854 Treaty of La Pointe with the region's Ojibwe, hard-bargaining Grand Portage band leaders such as Adikoons secured a reservation within their traditional territory instead of being displaced west. The future state park was originally part of the reservation, but became tax-forfeit and was bought by whites. In the 1890s the Alger, Smith and Company began logging on both sides of the border. In 1899 a series of sluices, dams, and flumes were built to float the logs safely around the waterfalls and gorges; remains of the wooden timber slide around the High Falls are still visible on the Canadian side.

The Guadalupe watershed was an area of intense activity during the California Gold Rush, with the quicksilver mines within Santa Clara County supporting the gold refinement process. Thus, mercury toxicity and its effects on surrounding humans and wildlife is a major concern for the area. Because mercury is an effective magnet for gold, miners during the Gold Rush would regularly line their sluices with Mercury to amalgamate the gold. An estimated 6,500 tons of mercury was lost in the system of creeks and rivers along the coast between 1850 and 1920, and is currently being detected today in the local streams, animal life, and riverbeds of these affected tributaries.

By the time it reaches Baltonsborough it is only some above sea level and the surrounding countryside is drained into it by way of numerous rhynes. It passes Glastonbury, where it acts as a natural boundary with nearby village of Street, before flowing in a largely artificial channel across the Somerset Levels and into the River Parrett at Burnham-on-Sea. It is joined by the North Drain, White's River (which takes the water of the River Sheppey, Cripps River (an artificial channel that connects it to the River Huntspill) and many drainage rhynes). It is connect to the River Axe through several of these channels which are controlled by sluices.

From there it turns to the west to reach the New River, which it follows northwards until its junction with the River Welland, which then forms the western boundary back to The Wash. Within this area, 92 per cent of the land is used for agriculture, with the remaining 8 per cent used for housing and industry. The board is responsible for of drainage channels, and maintains 17 pumping stations and 30 sluices and other structures to control water levels within its catchment. The Environment Agency are responsible for the main rivers, and the of sea defences which protect the area from inundation by the sea.

This dam was blocked by the Kornwerderzand Position, which protected a major sluice complex regulating the water level of Lake IJssel, which had to be sufficiently high to allow many Fortress Holland inundations to be maintained. The main fortifications contained 47 mm antitank-guns. Long channel piers projected in front of and behind the sluices, on both the right and left; on these, pillboxes had been built which could place a heavy enfilading fire on the dam, which did not provide the slightest cover for any attacker.Amersfoort (2005), pp. 324–325 On 13 May the position was reinforced by a 20 mm anti aircraft battery.

Paxton's Tower near Llanarthney in the River Tywi valley In 1789, Paxton bought the Middleton Hall estate, in Carmarthenshire for about £40,000. Turning the original hall into Home Farm, he commissioned architect Samuel Pepys Cockerell to design him a new home, which was built between 1793 and 1795. Paxton employed engineer James Grier as estate manager, and surveyor Samuel Lapidge, who had worked with Lancelot "Capability" Brown, to design and landscape the gardens. The pair created an ingenious water park, with water flowing around the estate via a system of interconnecting lakes, ponds and streams, linked by a network of dams, water sluices, bridges and cascades.

Cuckney CofE Primary School, History, accessed 2010-06-21 The drop in level of some between the mill pond and the river beyond has enabled the school to harness the river to generate electricity. Its 7 kW crossflow turbine generating a significant proportion of the energy used by the school, was funded by a grant from Powergen's Green Plan fund and a Clear Skies grant. Flowing around the northern edge of Cuckney, the river reaches the site of a second corn mill which was situated to the east of the village. The mill has been demolished, but the sluices and weir are still visible.

The Yauza reaches its maximum width of 65 meters three kilometers from its inlet, near the sluices south from the former German Quarter. A barge is filled with rubbish dredged from the river. Inflatable barrier visible on the surface traps the flotsam and directs it to the dredging boat on the left. The industrialization of the Soviet period polluted the Yauza drainage basin to a point where "an oil-soaked tributary of Yauza burst into flame in 1971"; the Yauza itself "was called a river only by force of habit... the biggest gutter for waste in Moscow" and caused a prominent surge in Moskva River pollution below the Yauza inlet.

East Beach and East Cliff. Before the mid 18th century, the harbour and river mouth were near the base of the grassy slope Bridport historically needed a harbour to export its principal products, rope and nets.Eastwood, p12 Originally the harbour was about inland, close to the town,Eastwood, p8 and its exit to the sea—the river mouth—was east of its current position.Eastwood, p7 The Anglo-Saxons and Normans struggled to keep the harbour open because the river mouth repeatedly silted up and was blocked by shingle from Chesil Beach, so eventually a system of sluices was devised to help keep it clear.

Built between 1800 and 1802, the canal initially provided an connection between Cassington Mill and the recently-constructed Cassington–Eynsham road. An early mention of the canal was in 1800, where the canal was described as "made by and belonging to" the Duke of Marlborough, and that its purpose was to convey goods between Cassington Mill and a wharf. A wide pool exists on the canal near Cassington Mill; this was possibly a basin which acted as the original terminus. Here, sluices and a weir between the cut and the River Evenlode were built. By 1802, the canal was extended to meet the River Thames.

With the city about above sea level, the docks and quays would have been well below the surrounding surface. Williams' plan was to dredge a channel between a set of retaining walls, and build a series of locks and sluices to lift incoming vessels up to Manchester. Both engineers were invited to submit their proposals, and Williams' plans were selected to form the basis of a bill to be submitted to Parliament later that year. The Manchester Ship Canal briefly became the longest ship canal in the world upon opening and at its peak in the 1960s, it was the third busiest port in Britain.

Iron Gate I dam Hydropower site Iron Gates (1970) The construction of the joint Romanian-Yugoslavian mega project commenced in 1964. In 1972 the Iron Gate I Dam was opened, followed by Iron Gate II Dam, in 1984, along with two hydroelectric power stations, two sluices and navigation locks for shipping. The construction of these dams gave the valley of the Danube below Belgrade the nature of a reservoir, and additionally caused a 35 m rise in the water level of the river near the dam. The old Orșova, the Danube island of Ada Kaleh (below) and at least five other villages, totaling a population of 17,000, had to make way.

In 1852 and 1853 he and Edward Matteson, while working at Buckeye Hill and American Hill respectively, devised the first hydraulic mining technology. It consisted of a wooden contraption held together by iron clamps that allowed miners to direct a fifty-foot column of water at a gravel bank using a canvas hose, which broke up the gravel and washed it into a series of sluices where the heavy gold flakes settled out of the lighter earth. Though it revolutionized gold mining, the technique also caused severe environmental damage. The vast quantities of sediment that were released in the blasting washed downstream, burying homes and farmland.

The Leesville Dam is a rolled earth fill with impervious core, maximum height 74 ft, top length 1695 ft, top width 25 ft, base width about 450 ft. With a 4.1 ft parapet wall on top of the dam with a top elevation of 995.1. Spillway: Uncontrolled concrete lined saddle spillway near left (south) abutment, crest elevation 977.5, length of crest 150 ft, design discharge with surcharge of 12.6 ft and freeboard of 5 ft. Outlet Works: Intake structure with three sluices controlled by 3.5 ft x 7 ft gates and discharges through a 7 ft diameter horseshoe tunnel through the right abutment into a stilling basin.

Burial site of the Bairds of Closeburn at Closeburn cemetery. The mill's water supply was not via the River Nith but was instead from the waters of the Lake Burn via a lade that ran down from Stepends and Whitespots Farms with a system of sluices, overflows and mill ponds. This water supply was part of the Garroch Waterpower Scheme that powered the Park limesrone works, Stepends Farm threshing machine, etc. The first record of Barburgh Mill (NX 90116 88316) is that John Padzean, the Covenanter, worked there in 1684, possibly as the miller as Thomas Macmurdy is also noted, but simply as a resident.

Much of the channel is managed by the Environment Agency as it is classified as a main river, while the upper river and the land drainage ditches which border the river are managed by the Upper Witham internal drainage board. In order the help protect the city of Lincoln from flooding, a sluice has been built across the channel at the Till Washlands site. When flooding is a possibility, the sluice is closed, and other sluices allow the surrounding farmland to be inundated until water levels start to fall again. The defences were first used in 2000, and successfully prevented flood damage in Lincoln in the summer of 2007.

This resulted in the construction of two washlands, one where the River Brant joins the River Witham, to the south of Lincoln, and the other on the River Till, to the north-west. Work began in 1984, and the two schemes can hold back of floodwater. In both cases, a shallow embankment was constructed across the river valley, and the river passes through a control sluice, which can be used to limit the volume of water travelling downstream. Inlet and outlet sluices in the embankments can be opened to allow the water to flood the Till washlands, rather than allowing river levels in the city to breach the defences.

This spur enabled the town gunner to protect the sluices that controlled the flow of seawater into a tidal moat used to power the water mill under the tower. The town gunner was also responsible for making the gunpowder and gunshot which he stored, together with the guns, in the gallery of the tower. By the start of the 17th century, the building had fallen into disrepair as the town no longer needed strong defences and in 1707 part of the building was being used as a house of correction. From 1786, it became the town gaol; at this time, the tower was known as the "Lambcote Tower".

Kublai knew the importance of water management for irrigation, transport of grain, and flood control, and he asked Guo to look at these aspects in the area between Dadu (now Beijing) and the Yellow River. To provide Dadu with a new supply of water, Guo found the Baifu spring in Mount Shen and had a channel built to move water to Dadu. He proposed connecting the water supply across different river basins, built new canals with sluices to control the water level, and achieved great success with the improvements he made. This pleased Kublai and Guo was asked to undertake similar projects in other parts of the country.

Sluices regulated water in the lake and within living memory the overflow went to The Clamp, another reservoir pond that had been constructed near the Serridge Pit. In the 1930s Bitterwell Lake received wide coverage in the newspapers that it was the home of Tarzan who lived in a tree-house and climbed like a monkey. An example is provided by The Mercury, in Hobart, Tasmania, that reported on 10 October 1934 that in the woods around Bitterwell Lake, near Bristol, is a man aged 20, who lives in the tree tops wearing only a leopard skin. His name is Bernard Skuse but he is known to his friends as Tarzan.

The Allersmaborg Church of Ezinge on the terp with left excavated terp as pastures and right the natural ice rink, Winter, 2012 Ezinge is located about 15 km from the city of Groningen and about 9 km from the former municipal capital of Winsum. The Allersmaborg (literally Borg (castle) of Allersma) was built in the 15th century on the banks of the Reitdiep river's meanders for economic and defensive purposes. Together with the nearby Aduarderzijl sluices, it acted as a strategic stronghold during battles in the Frisian civil war, the Eighty Years' War and the Siege of Groningen respectively. The borg was later extended into a manor house.

A mill leat, now filled in, ran for over three quarters of a kilometre from the sluices just downstream of the Doncombe Brook confluence to an overshot wheel in a fulling mill on this site. In the 1890s, rag processing machinery was installed at the mill, and the undershot wheel, which can still be seen on the derelict site dates from that time, being served by a much shorter leat from the next sluice upstream from the mill. Also clearly identifiable on the site is the remains of a rag boiler. The mill, demolished in 1964, processed rags into individual fibres or "stuff", which was transported in vats of elm across the bridge to Chapps Mill for paper making.

The three parallel channels pass under King's Ride and another track, before they skirt round the back edge of military housing that forms part of the Royal Military Academy Sandhurst estate. Here the three channels are inter-connected with sluices, and one of them enters a large tank, in an area which is described as a "water catchment area".Ordnance Survey, 1:2500 map, 1962-1972 The stream was important for the Academy, as it provided sufficient water to supply all of their needs, even in the summer months. The water is surface drainage from the surrounding moorlands, and tanks in the bed of the river collected the water, which was pumped to reservoirs by a steam engine.

The outflow to the Seine River is controlled by the Lac des Mille Lacs Dam, owned by the Ontario Ministry of Natural Resources (OMNR) and operated by the Valerie Falls Limited Partnership (Brookfield Renewable Power). The first dam at the site was built of stone by Simon James Dawson of the Department of Public Works Canada in 1873 to improve water flow for navigation to the vicinity of the Red River of the North far downstream. This dam was replaced in 1926 by a timber dam to regulate water flow used for hydroelectric power production downstream on the Seine River and Rainy River. The current concrete structure was built in 1952 with seven sluices, each with eight logs.

Dean Mills Reservoir is a small water reservoir to the north of the town of Bolton, Greater Manchester located high on the slopes of Winter Hill. The reservoir was constructed above the village of Barrow Bridge by John and Robert Lord. “The Lord Brothers opened a mill there in the late 18th Century using Crompton's spinning mules. With the success of this operation they built a water-powered mill further down the valley and carried out ambitious waterworks including the construction of a reservoir, waterfall and sluices to power the mill.” The dark brown appearance of the water in the reservoir is due to discolouration from the surrounding peat that naturally drains into the reservoir.

Amiriya School, built of qadad A minaret of the over 1300-year-old Great Mosque of Sana'a in Yemen, which is built with qadad. It is now being restored Qadad (, qadâd, kʉðað) or qudad is a waterproof plaster surface, made of a lime plaster treated with slaked lime and oils and fats. The technique is over a thousand years old, see Great Mosque of Sana'a with the remains of this early plaster still seen on the standing sluices of the ancient Marib Dam. Volcanic ash, pumice, scoria (), in the Yemeni dialect, or other crushed volcanic aggregate are often used as pozzolanic agents, reminiscent of ancient Roman lime plaster which incorporated pozzolanic volcanic ash.

Former water- meadows are found along many river valleys, where the sluice gates, channels and field ridges may still be visible (however the ridges should not be confused with ridge and furrow topography, which is found on drier ground and has a very different origin in arable farming). The drains in a derelict water-meadow are generally clogged and wet, and most of the carrier channels are dry, with the smaller ones on the ridge-tops often invisible. If any main carrier channels still flow, they usually connect permanently to the by- carriers. The larger sluices may be concealed under the roots of trees (such as crack willows), which have grown up from seedlings established in the brickwork.

Control of the central area around Ismaïlia was of great strategic importance because these three canal towns relied on fresh water from the Nile via the Sweet Water Canal to the main gates and sluices near there.Bruce 2002, pp. 15–17 At the beginning of hostilities between Britain and the Ottoman Empire in November 1914, the 30,000 strong British defence force evacuated the part of the Sinai Peninsula that was east of the canal, concentrating their defences on the western side of the canal. The British force comprised the 10th, and 11th Indian Divisions, the Imperial Service Cavalry Brigade, the Bikaner Camel Corps, three batteries of Indian mountain artillery and one Egyptian artillery battery.

During the Italian Campaign the re-establishment of electric power supplies was critical. Power stations in the south of the country were quickly captured intact, but north of Naples and Foggia the Germans had destroyed everything to do with electricity supply: power stations, sub-stations, hydro-electric dam sluices, transmission lines and pylons were all wrecked. Repair was a collaborative effort of the British Royal Engineers and Royal Navy with US and Italian engineers, under an Electric Power Committee set up in December 1943. Once the Allies reached Rome in mid-1944 they discovered that less than 10 per cent of the 800,000 kW generating capacity of central Italy was in working order.

Since the drainage works of 1981, access to the Idle is through the two sluice gates at the mouth of the river, and so the Environment Agency, who are responsible for the waterway, require 48 hours notice of intent to enter the it. There is also a high toll for doing so, with the result that most boaters that enter the river do so as part of a group, so that the cost can be shared. The space between the two sluices is effectively used as a very large lock, capable of holding a number of boats. Entrance through the first sluice is only possible for an hour either side of high tide.

During the 18th century, silting threatened the rich port of Sandwich and efforts were made to create sluices and channels to control the waters. These ultimately failed, and as a result Sandwich is now some distance from the sea. Regarding the northern end of the Channel, it has been estimated that the Roman fort at Reculver was originally about 1 mile (1.6 km) from the sea to the north, but by 1540, when John Leland recorded a visit there, the coastline to the north had receded to within little more than a quarter of a mile (400 m). It may be that sediment from this erosion contributed to the blocking of the north mouth of the Wantsum.

Onze-Lieve-Vrouw Onbevlekt Ontvangen church in Hansweert The first mention of what later is called Hansweert is made in 1353. Variants of the name include Hannekinswaerde, Hannekijnswaard, and Hanzwartz; the last of those is probably the source for the modern variant Answest. For a long time Hansweert was a small, agrarian community; it was notable only for the Hansweert-Walsoorden ferry, which dates from the 16th century and connects Hansweert in Zuid-Beveland to Walsoorden in Zeelandic Flanders. In 1866, however, when the Canal through Zuid-Beveland opened up, the village flourished; the canal ran right through the middle of the village (dividing it into eastern and western parts) where sluices were located, bringing commercial traffic with it.

The volume content of the dams is . The gross storage capacity created is at the Full Reservoir Level (FRL) of . The spillway, structure has an Ogee shaped downstream slope designed to dispose a design flood discharge of (the maximum probable flood discharge of and a breaching section is provided between the NOF block and the earth dam section, controlled by 41 radial gates of x size erected over the crest of the dam. In addition, four river sluices (gate controlled) are also provided in the body of the spillway pier numbers 3, 4, 5 and 6 with outlet level at , with each sluice designed for a discharge capacity of for silt flushing.

After passing under the A4174 the Frome enters a more urban environment passing between Frenchay on the right and Bromley Heath and Downend on the left. Turning in a more south westerly direction the river enters Oldbury Court estate, a city park also known as Vassal's, where it is joined by the first of two Fishponds brooks both on the left. The river then passes Snuff Mills, entering a steep valley at Stapleton, where the second Fishponds brook joins, then passing Eastville park, where it feeds the former boating lake. The river then flows under the M32 motorway and parallels its course for a while before disappearing into an underground culvert at Eastville Sluices, upstream of Baptist Mills.

The writers of those times, including Vitruvius, Frontinus and Pliny the Elder, treat these engines as commonplace, so their invention may be more ancient. By the 1st century AD, cattle and horses were used in mills, driving machines similar to those powered by humans in earlier times. According to Strabo, a water powered mill was built in Kaberia of the kingdom of Mithridates during the 1st century BC. Use of water wheels in mills spread throughout the Roman Empire over the next few centuries. Some were quite complex, with aqueducts, dams, and sluices to maintain and channel the water, along with systems of gears, or toothed-wheels made of wood and metal to regulate the speed of rotation.

The 1899 OS map shows Chapel Arches having water in three substantial arches, above a large lake at Ives Place where the present library is situated. Long before today's pound locks were built on the main River Thames, the old waterways were controlled by 'flash locks', consisting of sluices or weirs with removable sections. Barges are believed to have once operated from wharves on both the main river and its side channels. Parts of the waterway are thought to have been in active use up to at least the 1920s, witness statements recalling having seen reeds being cut for thatching and also timber being unloaded from a barge at Willow Wharf in the Moor Cut channel on Town Moor.

When built, wooden vertical sluice gates made of heavy boards of size in thickness, width, and more than in height, were operated by a rope and pulley arrangement to control flow of water; the wooden gates have since disintegrated but the gate groves are visible in each bay. The gates of the sluices were closed as a defensive measure against possible attack in the dry season when no storage remained in the dam. Each bay of the weir has an arched opening. On both banks of the weir identical towers (defensive bastions, projecting on the south and north sides) of diameter, but with octagonal shape chambers, are built, which once functioned as madrasa (Islamic school of learning).

In 1976 there were three rail-mounted cranes at the quay, two had been built by Alexander Chaplin & Co, Glasgow, and one by Smith Rodley.RCAHMS Retrieved : 2012-11-18 A considerable number of railway freight sidings at one time ran down to the harbour quays and the nearby chemical works in the time of the Glasgow and South Western Railway and later the London, Midland and Scottish railway. The harbour is no longer connected with the national rail network. In 1832 a plan of Irvine shows the presence of a shipbuilding yard, and features such as the small lochan known as 'The Sluices', lime kiln, lime mill, a single pier, and a flagstaff.

Hendrik Geeraert Nieuwpoort franc banknote Hendrik Geeraert (15 July 1863, Nieuwpoort, Belgium – 17 January 1925, Bruges) was a Belgian folk hero who, during the interwar period, came to symbolize the Belgian resistance movement against the German forces in World War I. He became famous among Belgian soldiers in 1914 after the Battle of the Yser where he, serving as a Nieuwpoort skipper, opened the sluices of the Yser River, flooding the polders and bringing the German advance to a halt. Geeraert was born at Langestraat 40 in Nieuwpoort, the son of the skipper Augustine Gheeraert and Anna Veranneman, a housekeeper and lace-maker. Hendrik became a riverboat skipper. At the age of 24, he married Melanie Jonckheerein in Veurne.

Having earned a mention in dispatches for his "Zeal and intrepidity" in the boat action with Potomac, Birchall was made a commander in 1797 and by 1798, had commissioned the lightly armed but fast troopship, Hebe. In May, she was serving in a squadron under Home Popham, sent to prevent the movement of a large number of enemy barges from Vlissingen to Dunkirk. The large flat-bottomed boats were to be used to convey troops across the Channel for Napoleon's planned invasion of the United Kingdom. At that time, the flotilla was travelling along the inland waterways of Belgium to Ostend, where the British hoped to stop them by destroying the lock gates and sluices there.

Fourteen Locks () is a series of locks, also known as the Cefn Flight, on the Crumlin arm of the Monmouthshire Canal at Rogerstone in Newport, South Wales. The flight of locks was completed in 1799 and raises the water level 160 ft (50 m) in just 800 yd (740 m). This is one of the steepest rises for a major run in the UK which, combined with the sheer number of locks, makes it one of the most significant in the country.Newport City Regeneration The run of locks includes a series of embanked ponds, pounds, sluices and weirs to control the water supply, with no set of gates shared between individual locks.

The river is generally thought to have given its name to Burnley (from the Old English ), with the name thought to mean the meadow or clearing by the brown river. However it is impossible to be certain that the town is not named after the brown meadow and river renamed after the settlement achieved some significance. West of Hurstwood the Brun flows under Salterford Bridge, the site of a ford on an ancient saltway. At the end of the Don are the remains of sluices and dams that supply water to the mill lodge for the old Heasandford Mill, historically located further downstream near the old manor house (thought to be anciently the pheasant ford).

It dams the Megget River, which flows into the loch, and impounds water from around half of the St Mary's Loch catchment. Aqueducts and pipelines convey the water to Glencorse Reservoir, dating from 1822, to Gladhouse Reservoir, dating from 1879, and to Rosebery Treatment Works, which was built in 1953. A second phase involved pumping water from St Mary's Lock into the Megget Reservoir, and controlling the outflow from the loch by the use of sluices. By 2008, there were 13 service reservoirs supplying Edinburgh, at Fairmilehead, Alnwickhill, Marchbank, Firrhill, Humbie, Hillend, Torduff, Clermiston, Harlaw, Kinleith, Langloan, Dunsapie, and Craig Park, which were supplied from four water treatment works, at Rosebery, Fairmilehead, Alnwickhill and Marchbank.

In Dark Emu: Black seeds: agriculture or accident?, Pascoe examines the journals and diaries of early explorers such as Charles Sturt and Thomas Mitchell and early settlers in Australia, finding evidence in their accounts of existing agriculture, engineering and building, including stone houses, weirs, sluices and fish traps, and also game management. This evidence of occupation challenges the traditional views about pre-colonial Australia and "Terra Nullius". The book also gives a description from Sturt's journal of his 1844 encounter with hundreds of Aboriginal people who were living in an established village in what is now Queensland (then part of New South Wales), in which a welcoming party offered him "water, roast duck, cake and a hut to sleep in".

Although in the subsequent the Treaty of Aix-la- Chapelle, signed by Spain and France on 2 May 1668 allowed Louis XIV to retain several towns in the Spanish Netherlands, he had to return three other cities there and the province of Franche-Comté to Spain. Louis consequently resented this Dutch intervention and used skillful diplomacy and money to detach England and Sweden from their alliance with the Dutch by April 1672. France then invaded the United Netherlands in May 1672 initiating the Franco-Dutch War. After initial successes and the Dutch offer of very favourable peace terms, which Louis refused, the Dutch retreated behind the inundations they had caused by opening river sluices and prepared to resist the French by land and sea.

Lade Bank pumping station on Hobhole Drain, where there was once a lock Historically, the drains were used for importing coal to the fens and exporting agricultural produce. They are now only used for pleasure cruising; this is restricted to the summer months, for between October and April, the water levels are maintained at a low level, so that there is scope to deal with high volumes of rainfall. Consequently, there is insufficient depth for navigation, and operation of the sluices can cause rapid changes in water level. Between April and October, their function is to provide irrigation water for agriculture, and so they are maintained at a higher level, although changes in level can still occur at short notice.

It included a towing path and several bridges, together with a number of sluices which enabled him to flood of his land in a controlled manner, thus creating water- meadows. As a catholic and a royalist, his property was sequestrated during the English Civil War and he fled to the Low Countries, where he studied inland navigations and the working of pound locks. He returned to England in the late 1640s, and proposed a scheme for making the Wey navigable to Guildford by the use of such locks. Guildford Corporation had petitioned Parliament in 1621 and 1624 for a scheme using flash locks, but there is no evidence that the proposals had been properly surveyed or costed, and nothing came of them.

The new route enabled a reservoir to be built over the old course of the canal, together with a steam-powered pumping engine. The tunnel did not last long, as it was opened out in 1858, necessitating the construction of a bridge to carry the lane which had previously crossed over the top of the tunnel. The bridge is now called High Bridge, and the lane is called Highbridge Road.Ordnance Survey, 1:2500 map The reservoir, which was built between 1835 and 1838, acted as a storage reservoir, so that when water was plentiful, as a result of rain, it could be pumped from the canal into the reservoir, and then released back into the canal through sluices near the tunnel when it was required.

Halted by budget issues, the plan was revived as a low-wage make-work project for the unemployed under the Great Depression-era Carnegie Commission of Investigation on the Poor White Question in South Africa. The idea was not only to provide immediate work but also land to settle employees on to relieve their poverty long-term. The project was among several launched by the Department of Labour. Work began on May 23, 1929, starting with a 622-m-long, 10-m-high retaining wall by Zeekoe Baard's Drift. 68 sluices were raised to filter floodwater and capture silt, and the retaining wall directed water to a canal and reservoir allowing irrigation to draw from the river all the way up to Augrabies Falls.

Loch of Lintrathen is a man-made loch occupying a glacial basin at the southern end of Glen Isla, approximately west of town of Kirriemuir in Angus, Scotland. The small village of Bridgend of Lintrathen lies on the southern shore of the loch, which is owned by Scottish Water and used as a water supply reservoir as well as an important wildlife site. The loch has been the main water supply for the city of Dundee and Angus since 1875. The water in the Loch of Lintrathen feeds down from Backwater Reservoir to the north and exits it via sluices at Bridgend of Lintrathen, flowing southward past Lintrathen Mill in the ‘Melgam Water’, which has a confluence with the River Isla farther south at Airlie Castle.

A watermill required a reliable steady supply of water; while this could be a river that ran at the same velocity throughout the year or a leat running from a river that provided a constant head, but more often a millpond would be built with sluices to regulate the head. A typical Arkwright type mill was wide internally, which provided space for two 48 spindle frames, while being narrow enough to support the wooden floor beams without the need of a central pillar. The pairs of frames would be placed one per window bay as natural light was the means of illumination. An overhead shaft running the length of the building turned wooded drums at floor level, which by means of leather belts powered the frames.

On 25 October, the German pressure on the Belgians was so great that a decision was taken to inundate the Belgian front line. After an abortive attempt on 21 October, the Belgians managed to open the sluices at Nieuwpoort during the nights of 26–30 October, during high tides, steadily raising the water level until an impassable flooded area was created of about wide, stretching as far south as Diksmuide. The Germans attacked again on the Yser front on 30 October, overran the Belgian second line and reached Ramskapelle and Pervijze. Belgian and French counter-attacks recovered Ramskapelle and the final attack, planned for the next day was called off when the Germans realised that the land behind them was flooding.

The first Acadians arrived in the early 1670s, as the French colony expanded from its base at Port Royal. Many of the Acadians came from the west of France and were experienced in reclaiming from the sea lowlands that might be made arable. The Tantramar Marshes were well suited to this, and the Acadians built a system of dykes and sluices that allowed them to cultivate the marshes. Surveyor Charles Morris visited in 1748, and reported Acadian settlements at Westcock; Pré des Bourgs, (Sackville); Pré des Richards, (Middle Sackville); Tintamare, (Upper Sackville); La Butte, Le Coup, Le Lac (Aulac); Portage, at the head of the Missaguash River; Beaubassin (adjacent to Beausejour); Jolicoeur, (Jolicure) and Pont à Buot, (Point de Bute).

Mining along the San Gabriel River began with simple gold panning, but soon developed to more advanced methods. Flumes were constructed to carry water to sluices, long toms and hydraulic mining operations that separated gold from river gravel; dams and waterwheels helped maintain the necessary head to drive these extensive waterworks and clear the riverbed so that gold bearing sands could be excavated. Some hard rock (tunnel) mining also occurred in the San Gabriels in later years, such as at the 1896 Big Horn Mine at Mount Baden-Powell, and the 1913 Allison Mine on Iron Mountain high above the East Fork, where several tunnels of up to in length remain. Settlements of considerable size were established in very rough country along the upper San Gabriel River.

Following favourable official assessments of the ore potential in King's freehold, a Melbourne syndicate bought into the Ravenswood Silver Mining Company and refloated it, under the same name, on the English market. With over 30,000 tons of tailings in the dumps, the new company proposed an elaborate treatment plant to be housed in an all brick building on One Mile Creek, connected by an endless chain tramway to the mine, at a cost of £15,000. The mill was completed in 1889 and equipped by Sandycroft and Company, of Chester U.K., with three engines aggregating 54 h.p., Cornish boilers, piston jiggers, stone breakers, two pairs of rollers, two raff wheels and elevators, classifier, three sluices, six Borleas round buddles, picking tables, three Frue vanners and a separator.

The name, which is recorded both as Watersheddles and Water Sheddles, is thought to have derived from Middle English meaning "the parting of the waters". The name is borrowed from a nearby boundary stone on the road between Stanbury and Laneshaw Bridge. Although the contract for the building of the reservoir was awarded to Walker and Taylor of Crewe in June 1870, the reservoir was not started until August 1871, with full use and final flooding in 1877. A deal was agreed with the mill owners along the River Worth that guaranteed a ready-supply of water; every morning and every evening, the sluices were opened to allow a regulated flow of water down the valley to enable the mills to restock their ponds.

The Guadalupe watershed was an area of high activity during the California Gold Rush, and as a result, Mercury toxicity and its effects on surrounding citizens and wildlife is a major concern for the area, and monitored intensively. Because mercury is an effective magnet for gold, miners during the Gold Rush would regularly line their sluices with mercury to amalgamate the gold out. An estimated 6,500 tons of mercury was lost in the system of creeks and rivers along the coast between 1850 and 1920, and is still being detected today in the water, animal life, and riverbeds of these affected tributaries. The effects of mercury on aquatic environments are very complex and create a number of health and safety risks.

The central span of the bridge (named the peltinée by its architects, Feichtinger Architectes, under Dietmar Feichtinger) is made of steel, weighs , is long and wide. The span was constructed by the Eiffel company (Eiffel Constructions métalliques) in the Alsace and was transported by canal, the North Sea, the English Channel and French rivers (with difficulties due to sluices being too narrow) to its destination, crossing Paris on a barge on November 30, 2005. It was hoisted in place in two hours on January 29, 2006, around three o'clock in the morning. The passerelle is characteristic of its time and distinguishes itself from the three other footbridges that already cross the Seine in Paris (Passerelle Solférino, Pont des Arts, and Passerelle Debilly).

As constructor of the Grimsby docks he was one of the first to apply W. G. Armstrong's system of hydraulic machinery for working the lock gates, sluices, cranes, etc. For this work he received a grand medal of honour at the Paris Exhibition of 1855. For the Admiralty he planned in 1845, and afterwards constructed, the packet and refuge harbour at Holyhead, and in 1847 he constructed the harbour of refuge at Portland. In the making of these great harbours he contrived, by means of elevated timber staging, to let down masses of stone vertically from railway trucks, and, by building up the masonry with unexampled rapidity to a point above sea level, contrived to reduce to comparative insignificance the force of the sea during building operations.

Although the mill was demolished in 1973, the beam pump and water wheel were saved for restoration, although the sluices and waterwheel paddles needed replacement. In 1976, the Sussex Industrial Archaeology Society received permission from the present Lord Egremont to restore the pump to working order. The restoration was undertaken voluntarily by the society members in order to eventually open the site to the public and was financed by grants from the Historic Buildings Section of the Inspectorate of Ancient Monuments, West Sussex County Council and the Department of the Environment as well as assistance from Lord Egremont, the owner of the land surrounding the installation. Work commenced immediately, and by October a temporary visitor centre was in place and regular fortnightly work sessions were under way.

The company was trading at a loss by 1871, and although an Act of Abandonment was obtained on 17 June 1878, the navigation did not actually close until 14 May 1881, which was also the date of the final meeting of the proprietors. The Act required the company to fill in the three locks nearest to Sleaford, but there were special provisions for the remaining structures. The next three were on a stretch of river bordered by land belonging to Haverholme Priory, and were to be put into good order and handed over to Murray Finch Hatton, earl of Winchilsea & Nottingham, who owned the Priory. He could then maintain or abandon them, but was required to construct sluices if he chose to abandon them.

On realising Fenella′s plight, Captain Mylchreest ordered her port anchor to be lowered and a hawser was got out from her starboard bow and made fast ashore. Soundings were then taken which showed a depth of 10 feet (3 metres) on the starboard quarter, four fathoms (24 feet; 7.3 metres) on the port quarter and seven fathoms (42 feet; 12.8 metres) on either side of the bridge. The sluices were closed and two of Fenella′s lifeboats were lowered into the water. The tide continued to ebb, causing Fenella to slip and heel over to port, exposing the damage incurred. Captain Mylchreest and his officers inspected the damage and found that a gash had been inflicted on her starboard side that was 10 inches (25.4 cm) long and 1 inch (2.54 cm) wide.

Smeaton then reviewed it, and suggested only minor modifications, as he was happy with all the major points. The land surveyor Charles Tate produced an engraved plan, and Grundy went to London to steer the bill for the scheme through Parliament. The bill became an Act of Parliament on 5 April 1764. Grundy's life was marked by tragedy shortly afterwards, when his wife of 21 years died, and remarkably personal letters between the two engineers have survived. Although busy with the Calder Navigation by then, Smeaton made the time to visit the area with Grundy on 4 July, in response to a request from the Trustees of the scheme to view the low grounds and carrs. Grundy produced a report on 14 July, and then designed the outfall sluice, which had two arches with sluices.

Much of the area, however, remained a lake, fed by water from the chalk springs on the edge of wolds to the north, from the Holderness clays, and from inundation by the tide twice a day. Following the Norman conquest, some form of defence against the tides was provided by the construction of earth banks along the Humber and the lower reaches of the River Hull. Ongoing maintenance was a problem, and in 1311 and 1313, King Edward II appointed ad hoc commissioners to repair some of the breaches that had occurred. While the embankments prevented the tide entering the area, they also prevented the fresh water from the north from leaving it, and drainage channels were cut to channel it to sluices through the main flood banks.

Watermills on Zala river in the end of 19th century For centuries, the watermills on the Zala river (Zala County, Western Transdanubia, Hungary) had co-existed in a single harmonious unity with each other as well as with the river, the Zala valley and Zala meadow, both latter ones renowned for their beauty. Landscape rehabilitation would indeed be necessary because due to the closure of the mills and the destruction of the sluices, the level of the ground water in the meadows, usually having very loamy soil, has dramatically decreased, which has had detrimental impacts on the condition of the meadows. The declining tendency in the grassland culture hasn’t helped either. What is more, in several cases parts of the meadows were turned into arable lands or industrial sites.

The new Act of Parliament created the Norwich and Lowestoft Navigation Company, and authorised them to raise £100,000, with an additional £50,000 if required. The scheme involved dredging of the River Yare from Norwich to Reedham, to make it deeper, construction of the Haddiscoe cut between Reedham and Haddiscoe on the River Waveney, enlarging of Oulton Dyke, between the Waveney and Oulton Broad, and linking of Oulton Broad to Lake Lothing by a channel which was long, and included a sea lock, so that it could be used at all states of the tide. Work began on the Lake Lothing link, with most of it completed during 1829. The lock was , and included a system of sluices, which used water from Oulton Broad to clear a channel to the sea through Lake Lothing.

Panning for gold in a creek bed Gold in the pan, Alaska Gold panning, or simply panning, is a form of placer mining and traditional mining that extracts gold from a placer deposit using a pan. The process is one of the simplest ways to extract gold, and is popular with geology enthusiasts especially because of its low cost and relative simplicity. The first recorded instances of placer mining are from ancient Rome, where gold and other precious metals were extracted from streams and mountainsides using sluices and panning. However, the productivity rate is comparatively smaller compared to other methods such as the rocker box or large extractors, such as those used at the Super Pit gold mine, in Kalgoorlie, Western Australia, which has led to panning being largely replaced in the commercial market.

The inadequacy of its outfall and a spate of bad weather stopped them from completing their task. They tried renting out the land they had been granted, but many tenants were unable to pay the rent, due to the poor state of the drainage which reduced crop yields. In April 1729, the Deeping Fen Adventurers received a letter from Captain John Perry, expressing the opinion that the only way to improve the drainage was to improve the river outfalls, and proposing the construction of scouring sluices on the river at Spalding, on Vernatt's drain at its outfall, and on the River Glen at Surfleet. Perry was an engineer of some repute, who had set the standard for engineering reports in 1727, when he published his recommendations for the North Level of the Fens.

The race was the first of its kind in the country and is still run annually, as the Bedford Canoe and Kayak Marathon. It now takes place on a circular circuit around the Victorian Embankment in Bedford's town centre and is part of the Eastern Region Hasler marathon series, generally taking place at the end of April or beginning of May. In 1961, following the success of the Bedford to St Neots race, Viking Kayak Club was established by canoeing friends Brian Sidaway, David Green and John Mathers and moved into premises shared with Star Rowing Club. From the start, Viking members have also used the white water created by Bedford's weirs and in particular Duck Mill sluices, in Bedford's town centre, which is ideal for white water training.

During the Canal du Midi modernisation program of the 1970s several of these multiple chambers were converted into single "deep" locks with concrete side walls. The lock gates were originally made of oak in the traditional mitre pattern with balance beams and each gate had a single large wooden sluice drawn up by a vertical screw. The introduction of electric and hydraulic systems for both the lifting of the sluices and the opening of the gates has seen the removal of the balance beams and modern gates are of metal construction. At each lock there is a double-fronted two-storey lock keeper's house upon which is fixed either a cast iron or a masonry sign showing the name of the lock and the name and distance to the adjacent locks in each direction.

During the German campaign in northern France in 1870, and especially after German armies began to advance on Paris to besiege it, it was critical for the German High Command to secure Toul, which controlled a railway line to Germany. Toul, located in a valley between the Marne–Rhine Canal and the Moselle, was protected by nine bastions, some outworks, water-filled ditches, including a -wide main ditch and a system of sluices to inundate the nearby ground. The 125-meter-high Mont St.Michel to the north, the Dommartin-lès-Toul heights to the east, the Choloy plateau to the south-west and the absence of bomb-proof cover rendered the fortification vulnerable to artillery bombardment and the hills and villages nearby made it easy for hostile infantry to advance to its ramparts.

The dam has a length of about and a crest height of up to . It consists of concrete-faced rockfill dams on each river bank (the right bank dam is the largest part of the project, 4.3 km long and 53m high; the left bank is 1590 metres long and 50 metres high), an -long -high earth-core rockfill dam (the 'main dam') in the left river channel, and a live water section in the right river channel (sluices, spillway and a 300-metre power intake dam with turbine housings). It contains a reservoir of , or about 15% of the Nile's annual flow of ; the intended reservoir level is 300 metres above sea level, with the Nile level downstream of the dam being about 265 metres. The reservoir lake is planned to extend upstream.

Vicomte de Turenne The French, in 1657, completed an alliance with the Lord Protector, Oliver Cromwell, in which the English Commonwealth would join in the war against Spain and supply troops and ships for a campaign in the Spanish Netherlands. In return, Cromwell made the support of a fleet and 6,000 soldiers conditional on the transfer of Dunkirk to the English once it had been taken. The treaty was renewed in 1658 and encouraged by the promised additions the French were early into the field capturing a contingent of Spanish troops in Cassel, marching by way of Bergues on Dunkirk. Turenne, with some 7,000 men was impeded by the heavy seasonal rains and by the opening of the sluices by his opponents which inundated all the low-lying ground in the area.

He used his great wealth to employ some of the finest creative minds of his day, including the eminent architect Samuel Pepys Cockerell, whom he commissioned to design and build a new Middleton Hall, turning the original one into a farm. The new Middleton Hall became ‘one of the most splendid mansions in South Wales’ which ‘far eclipsed the proudest of the Cambrian mansions in Asiatic pomp and splendour’. Paxton created an ingenious water park. Water flowed around the estate via a system of interconnecting lakes, ponds and streams linked by a network of dams, water sluices, bridges and cascades. Spring water was stored in elevated reservoirs that fed into a lead cistern on the mansion’s roof, allowing Paxton’s residence to enjoy piped running water and the very latest luxury, water closets.

View over the northern part of Meldorf Bay from Speicherkoog Harbour looking towards Büsum When the last dykes were built from April 1969 to March 1978, taking in an area of about 8.5 x 8 kilometres, Meldorf Bay was left with an (estimated) area of 30 km². The construction of the latest dykes was not, however, primarily aimed at land reclamation but coastal defence. For example, by building new, 8.8 metre high dykes that were only 14.8 km long (in the core area of the bay), the crest of the dyke was raised significantly and the length of the dyke greatly shortened. The newly created Speicherkoog on Meldorf Bay is designed primarily to store water from the interior during inland flooding and to discharge it into the sea through two dyke sluices and scoop wheels.

On 18 August, General Albert d'Amade formed a defence line from Maubeuge to Dunkirk, to prevent the disruption of railways by German cavalry raids. The Scarpe, Escaut and Rhonelle sluices were opened to extend the floods of the Scarpe and the old forts of de Maulde, Flines, Curgies, Condé and Le Quesnoy around Valenciennes were re-occupied. On 20 August, d'Amade formed a line of three territorial divisions de campagne, with the 84th Territorial Division from the Scarpe to the Sambre, the 82nd Territorial Division from the Sambre to the Lys and the 81st Territorial Division from the Lys to the sea. When the BEF advanced to the west of Maubeuge, the 84th Territorial Division advanced to Condé and formed a new defensive line along the Escaut, from Condé to Maulde.

The approach to Dunkirk was made difficult as the inhabitants had opened the sluices and flooded the area, but Turenne persisted and opened the trenches on the night of 4/5 June. A Spanish army under the command of Don John of Austria, consisting of about 15,000 men, moved to raise the siege. It was divided in 2 corps, the Spanish Army of Flanders on the right and centre and the small corps of French rebels, of the Fronde, on the left under the command of Condé. The Spanish army included Spanish, German and Walloon troops, and a force of 2,000 English/Irish Royalists – formed as the nucleus of potential army for the invasion of England by Charles II, with Charles' brother James, Duke of York, amongst its commanders – was sent to relieve the town.

Vandamme met with an obstinate resistance, the sluices were opened, and his siege batteries inundated, and when abandoning the regular attack he attempted a night assault on 25 October, his front was so limited between the river and the inundation that Wilson, with his two guns placed to command the enemy's approach, was able by firing rapidly into the advancing foe over one hundred rounds of grape and round shot, to create such fearful havoc that the French withdrew just at the critical time when enlarged gun-vents and distorted muzzles were rendering Wilson's guns useless. The arrival of British forces on 29 October caused Vandamme to raise the siege on the following day, leaving his battering guns behind. The successful defence was ascribed by all concerned to the artillery and the 53rd Foot.

Maitland worked on the water flow through the ponds, building sluices, a dam and washing screens to control the amount of water and also what was flowing through the water into the ponds. The diet of the fish was an important factor, and Maitland tried a few different options, sheep heart, rabbit liver and horse spleen-which when ingested by trouts causes blindness and nutritional cataracts, before sticking with a diet of horsemeat, shellfish and eggs. Throughout his time at Howietoun, Maitland was meticulous at writing up reports on the fish, he collected and recorded as much information as he could about the fish and all his experiments were well documented. Maitland stuck to the classic scientific method, the one variable that was changed was monitored, the experiment was observed and recorded, then the results were recorded.

In addition, from the position of the axis of the Ming and Qing Beijing city view, its axis eastward from Zhengyang and Chongwenmen is less than the distance between the between ZhenYangMen and Xuanwumen. A second expansion of the city occurred between 1436 and 1445, on the orders of Emperor Ying of the Ming dynasty. Major works included the addition of an extra layer of bricks on the interior side of the city walls, creating the southern end at Taiye Lake, construction of gate towers, barbicans and watchtowers at nine major city gates, construction of the four corner guard towers, setting up a Paifang on the outside of each major city gate and replacing wooden moat bridges with stone bridges. Sluices were built under the bridges and revetments of stone and brick were added to the embankment of the moat.

In 1828 the 'Paisley Magazine' recorded that the minor poet Alexander Wilson, who lived at Auchenbathie Tower, wrote a poem "Rabbie's Mistak" concerning the hunting exploits of Robin Stirrat from Lochhead, the setting being Millbank Glen. In 1814 a scheme was carried out to drain the Barr Loch however the water level at the lowest point of the loch was too low to drain away naturally into the canal so a water-driven pump was installed at Hole of Barr to raise the water from the loch bed into the canal. Later this was converted to steam power and a tall chimney built. The ‘Barr Meadows’ was around 170 acres and were used for growing oats or for rough grazing until in 1946 a lack of maintenance of the sluices led to the loch bed flooding once more.

The dike and dam system on the Red River had been expanded steadily since independence was declared and by 1972 consisted of nearly 2500 miles of dikes, levees, dams and sluices. Heavy monsoon rains coupled with the preoccupation of the civilian population that normally maintained the water works, led to extensive flooding in 1971. In an attempt to garner international opposition against the newest U.S. strategic bombing campaign, Rolling Thunder, the North Vietnamese Government began a propaganda campaign using images of the flood to allege that the U.S. had begun a strategic bombing campaign against the Red River dikes. Given the North Vietnamese tactic of forcing U.S. aircraft to jettison their bombloads and abort their missions, the dikes undoubtedly were their point of impact on occasion, as well they may have been for some downed U.S. aircraft.

Tokyo floodgates created to protect from typhoon surges Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or storm surge system. Since most of these devices operate by controlling the water surface elevation being stored or routed, they are also known as crest gates. In the case of flood bypass systems, floodgates sometimes are also used to lower the water levels in a main river or canal channels by allowing more water to flow into a flood bypass or detention basin when the main river or canal is approaching a flood stage.

At high tide, the level of the river was above that in the meadows. The same applied to Ranscombe brooks, to the north of the junction between the Ouse and the Glynde, Further down river, at White Wall and Tarring, the brooks were generally dry, which he attributed to the land surface being higher, the walls being higher and well maintainted, and the outfall sluices from the meadows being arranged at a lower level in relation to the river. He noted that the rise and fall of the tide below Broad Salts, a little below Piddinghoe, was some , but this was reduced to just at the mouth of the Glynde, and was barely visible at Lewes Bridge. A series of shoals, combined with the narrow and winding channel, held water back, and prevented it from draining from the levels.

Ordnance Survey, 1:2500 map, 1872 and 1896 By 1969, the upper area was again a pond, covering , and there were three sluices to allow water to pass through the embankment, with another sluice controlling the outflow from the lower pond.Ordnance Survey, 1:2500 map, 1969 Just to the south of the pond is The Frith, an Iron Age Hill fort, where a single line of earthworks, which are quite modest in scale, enclose the top of a hill. The enclosure is by and there are no records of archaeological excavation being carried out on the site, although parts of it near its entrance have been damaged by tree planting. Silchester Roman Town is located around to the south-east, and the fort may have been associated with the Iron Age town that pre-dated the Roman one.

Although the Environment Agency maintains the river, it is not the navigation authority for the Idle, as the river does not have one. There has been some speculation as to what the position would be if the Canal and River Trust became the navigation authority for Environment Agency waters, a move that has been proposed but not yet implemented. The Environment Agency have also suggested that the river outfall might be reverted to gravity drainage, by leaving the pumping station sluice open and routinely opening the final sluice at low tide. Newman has suggested that access to the river could be significantly enhanced by the construction of a channel between the river and the Chesterfield Canal at West Stockwith, which would avoid the need for boats to navigate through the sluices, and effectively separate the drainage and navigation functions of the river mouth.

Part of the Frome Valley Walkway: a alt= a river flowing over a weir, trees surrounding on a sunny day, blue sky, dark pool in foreground Where it passes through Bristol the river was prone to flooding, but the Northern Stormwater Interceptor, running from Eastville Sluices to the River Avon downstream of Clifton Suspension Bridge, has since been constructed to control this. At Wade Street, St Judes, the river enters an underground culvert, emerging at what Bristolians call The Centre (formerly the 'Tramways Centre'), but only when there is a risk of flooding. The river is otherwise channelled through Mylne's Culvert into the River Avon at a point between Bathurst Basin and Gaol Ferry Bridge. Three further flood relief tunnels- Castle Ditch, Fosseway and Castle Green Tunnel - run under Castle Park in central Bristol to carry excess flows into the Floating Harbour.

The brooks on the west level and at Ranscombe would need better embankments, and adequate sluices to allow water to drain away when required. A second option involved raising the banks on all of the meadows, and constructing a separate sewer to carry surplus water from them to the sea, leaving the main river largely unaltered. The outfall sluice would have been located at Tarring Tenantry near Piddinghoe, and would contain three openings, two of , each with a set of pointed doors facing in opposite directions, to prevent the sea entering the river, and to retain water in the river during dry periods. The third opening would be wide, with double pointed doors facing in both directions, so that it could additionally be used as a navigation lock at all states of the tide and river.

Jobe returned in the Spring of 1819 with a herd of cattle in tow, and gave the Olivers two milk cows to ease their complaints.Dunn, 1-9. In 1821, William "Fighting Billy" Tipton (1761–1849), a veteran of the American Revolution and son of State of Franklin opponent John Tipton, bought up large tracts of Cades Cove which he in turn sold to his sons and relatives, and settlement began to boom. In the 1820s, Peter Cable, a farmer of German descent, arrived in the cove and designed an elaborate system of dykes and sluices that helped drain the swampy lands in the western part of the cove.Dunn, 16-17. In 1827, Daniel Foute opened the Cades Cove Bloomery Forge to fashion metal tools.Dunn, 20. Robert Shields arrived in the cove in 1835, and would erect a tub mill on Forge Creek.

The Environment Agency has obtained a "significant proportion" of the £8m required for phase one. Starting from the north, the first development was the provision of a new tidal lock from the Haven in Boston to the South Forty-Foot Drain at the Black Sluice, opened to traffic on 20 March 2009. Funding for phase two of the project, which will involve widening of the South Forty-Foot Drain from Donington to a new road crossing under the A151 road, a new lock and a junction with the River Glen, a tributary of the River Welland, at Guthram Gowt has been secured from the East Midlands Development Agency.Lincolnshire Waterways Partnership, Newsletter, March 2008 To connect the Glen to the Welland requires a new tidal lock at the Surfleet Sluices and reconstruction of the tidal Fulney Lock in the River Welland, leading to Spalding.

The presence of the Dutch engineer Cornelius Vermuyden, a relation of Croppenburg's, in England at the time of the project on a commission to drain the Fens and involved in repairing the seawall at Dagenham, has led to speculation that Vermuyden oversaw the project, but proof appears to be vague; nevertheless, the work was completed by around 300 Dutch workers skilled in the construction of dykes and other sea defences. The engineers successfully reclaimed by walling the island with local chalk, limestone and the heavy clay of the marshes, with the main length along the Thames faced with Kentish ragstone. A broad drainage ditch was dug inland off the area facing the river while smaller inlets were filled in. Excess water would have collected in the broad ditch and then been discharged into the river by the means of seven sluices (later known as Commissioners Dykes).

This section diverts water from the Crane in Kneller Gardens, Whitton, Twickenham, eastward then northward past The Stoop and Twickenham Stadium rugby stadiums, through Isleworth (originally to its mill), then onwards to supply the ornamental ponds in the Duke of Northumberland's estate at Syon Park. Further sluices here control the flow into the park and the River Thames at Isleworth Ait. This part is the older -- it was built in the time of Syon Abbey, over 100 years before it was inherited, in 1594, by wife of the "wizard earl", Henry Percy, 9th Earl of Northumberland, Dorothy (née Devereux) which automatically became his own as this inheritance preceded the Married Women's Property Act 1870. The Duke of Northumberland's River can thus be described as a distributary of the Colne and a tributary of the Crane; it is also a distributary of the Crane and a tributary of the Thames.

The non-tidal section of the river is managed by the Environment Agency, which is responsible for managing the flow of water to help prevent and mitigate flooding, and providing for navigation: the volume and speed of water downstream is managed by adjusting the sluices at each of the weirs and, at peak high water, levels are generally dissipated over preferred flood plains adjacent to the river. Occasionally, flooding of inhabited areas is unavoidable and the agency issues flood warnings. Due to stiff penalties applicable on the non-tidal river, which is a drinking water source before treatment, sanitary sewer overflow from the many sewage treatment plants covering the upper Thames basin should be rare in the non- tidal Thames. However, storm sewage overflows are still common in almost all the main tributaries of the thames despite claims by Thames Water to the contrary.

London Mithraeum, ruins of the cult of Mithras stemming from ancient Persia by way of the Romans The construction of the massive infrastructure of the London sewerage system, with five main sewers, incorporated many existing culverts, storm sewers, and sluices. This included the culverted Walbrook, which by 1860 had been linked into a network of 82 miles of new sewerage lines, channelled to the Northern Low Level Sewer at a point near the Bank of England. Many small leaks stream into the rounded sewer for much of the year when the water table is high enough. On 18 June 1999, during the "Carnival Against Capitalism", timed to coincide with the 25th G8 summit, fire hydrants were opened along the route of the Walbrook by Reclaim the Streets, symbolically releasing the river to "reclaim the street" from the "capitalist forces" of city growth which had subsumed it.

Bittern The impetus for creating the Ham Wall reserve was the plight of the bittern, with only 11 males present in the UK in the 1997 breeding season. Much of its reed bed habitat was deteriorating, and key coastal sites in eastern England were at risk of saltwater flooding, so an opportunity to create a new inland site was attractive to the RSPB. The peat excavations already had bund walls that allowed the water levels on the reserve to be easily managed in sections, and the workings had removed peat down to the underlying marine clay, a depth of in this area. Water levels were managed using sluices, pipes and wind-pumps to create reed beds with about 20% open water, and the ditches were deepened and widened to restrict reed encroachment and provide a habitat for fish, particularly common rudd, introduced to provide food for the bitterns.

Send is a lightly dispersed village centred south-west from Charing Cross and south-west of junction 10 of the M25Grid Reference Finder distance tools and has a developed clustered centre on the old course of the Portsmouth Road which bisects the highest settled part of the village, Burntcommon, which is on the start of rise of the London Clay. This road was relieved by the construction of a six-lane bypass, part of the A3 trunk road, which now forms the long south-east border of the village. The other principle road is the A247 Woking to West Clandon road which passes through the village from north to south. The parish is bounded to the west and part of its northern side by the River Wey, which is controlled by sluices and has been expanded in capacity by a navigable channel running alongside, the Wey Navigation.

The same applied to Ranscombe brooks, to the north of the junction between the Ouse and the Glynde, Further down river, at White Wall and Tarring, the brooks were generally dry, which he attributed to the land surface being higher, the walls being higher and well maintained, and the outfall sluices from the meadows being arranged at a lower level in relation to the river.

A series of shoals, combined with the narrow and winding channel, held water back and prevented it from draining from the levels. He also commented on the great shingle bar crossing the mouth of the river at Newhaven, which if removed would allow the water levels to be around lower at low tide.

This ultimately resulted in the two becoming famed as heroic figures.Gadeleva (2000). p. 173-174. A prayer or norito originally recited by the priestly Nakatomi clan in the presence of the court during the Great Exorcism (大祓 Ōharae) ritual of the last day of the sixth month, more commonly known today as the Ōharae no Kotoba (大祓詞 'Words of the Great Exorcism'), lists eight "heavenly sins" (amatsu-tsumi), most of which are agricultural in nature: # Breaking down the ridges # Covering up the ditches # Releasing the irrigation sluices # Double planting # Setting up stakes # Skinning alive # Skinning backward # Defecation 1, 2, 6, 7 and 8 are committed by Susanoo in the Kojiki, while 3, 4, 5 are attributed to him in the Shoki. In ancient Japanese society, offenses related to agriculture were regarded as abhorrent as those that caused ritual impurity.Philippi (2015). pp. 403-404.

The place is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in New South Wales. The two mills and the connecting waterways allow for examination of the cultural maritime landscape of the 1820s; They demonstrate the early development of the milling industry as well as the transport networks that supplied the mills, distributed their products and integrated their operations; Visible surface remains of the mills include cuts in the bedrock made with rock picks, holes drilled into the rock and stone and cement dam walls and channels. These indicate the locations and functions of the mill dams, wheel pits, races, sluices and other structural rock, which, together, demonstrate the evolving understanding of water utilisation along these particular bodies of water. The place has potential to yield information that will contribute to an understanding of the cultural or natural history of New South Wales.

Yerra Kaluva Reservoir was constructed in the year 1976. The Yerrakalva Reservoir Project is a medium irrigation project comprising an Earthen Dam formed across the river Yerrakalva near Konguvarigudem village in Jangareddigudem mandal of West Godavari district. The ayacut proposed to be irrigated by this project is 9,996 ha benefitting 22 villages in Jangareddigudem, Kamavarapukota, Dwaraka Tirumala, Nallajerla and Tadepalligudem mandals of West Godavari District. Besides this, flood moderation is provided for safeguarding the fertile lands of about 8,094 ha between Anantapalli and Nandamuru Aqueduct on both flanks of the rivers. The project components are as under: (i) Earthen Dam for a length of 2.73 km. (ii) Spillway Regulator with Hoist Bridge with 4 Vents of size 12.00 m. x 5.00 m. (iii) Left and Right Head Sluices at km.0.40 and km.2.20 of Earth Dam respectively. (iv) Excavation of Left Main Canal (LMC) for a length of 7.59 km. and Right Main Canal (RMC) for a length of 45.60 km.

The term Dijkgraaf (official) only began to be used around 1400, when the water district borders differed greatly from the borders of the nearby municipalities. The success of the Zijl and Does river outlets was not enough to avoid heavy floods, and in 1248, a heavy storm again caused a lot of damage, so a dam was built at Spaarndam. This caused a fierce dispute with Haarlem, since that city was dependent on free access for ships to the IJ. The dispute was solved by building an extra sluice in 1253 for ships that could pass when the water levels on both sides of the sluice were the same.De Kleine Haarlemmer sluis on the website of the North Holland Archives To emphasize that control over the sluices and dikes at Spaarndam were under the jurisdiction of the Hoogheemraadschap van Rijnland, Count Willem II granted the privileges to levy a toll on ships to the Dike wardens, and not to the city of Haarlem.

Water levels in reed beds are managed using sluices, pipes and wind-pumps, with deep wide ditches to restrict reed encroachment and provide a habitat for fish, particularly the common rudd, introduced to provide food for the bitterns at Ham Wall, which along with Lakenheath Fen in Suffolk, has been a key part of a bittern recovery programme initiated in 1994 as part of the United Kingdom Biodiversity Action Plan. Both reserves created extensive new reed beds, thereby adding significant additional breeding habitat. Westhay Moor, in addition to former peat-working habitats, has the largest area of acidic raised bog in the region, with Sphagnum mosses, cotton grass, sundews and other typical species of the habitat. Shapwick Moor had been drained and converted to arable farmland when it was enclosed in the eighteenth century, but since its purchase it has been managed as hay meadow, with late summer cutting, no fertilisers, and grazing by cattle.

Brunel's method of silt disposal is still in operation today, but the silt is carried in mud barges or pumped to the sluices through a quayside pipe system from the more efficient modern 'Cutter-Suction' dredgers. During the 20th century the western parts of the yard were leased to P & A Campbell Ltd, operators of the White Funnel Line of paddle steamers as a maintenance base. The yards have been little altered recently except for the replacement of the three-storey 'A' block over the sluice paddle room resulting from bomb damage in World War II. Underfall Yard has been refurbished under the management of the Underfall Yard Trust (previously Underfall Restoration Trust) thanks to the Heritage Lottery Fund, AiM Biffa Award, and donations from various organisations and trusts. Based at the yard at the moment are maritime academies, a scout sailing section, a blacksmith, rigging company, Omni, and three boat building businesses.

This platform is protected on its up-stream and down-stream sides by a continuous and impermeable line of cast iron tongued and grooved sheet-piling with cemented joints. This piling extends into the sand bed of the river to a depth of below the upper surface of the platform and prevents it from being undermined. The river bed is protected against erosion for a width of upstream by a stone paving laid on a puddle clay blanket to check infiltration, and on the downstream side for the same width by a stone paving having an inverted filter bed underneath, so that any springs that may be caused by the water above the sluices shall not carry sand with them from beneath the paving. The piers between the openings have a length of up and down stream and are wide with the exception of every thirtieth pier, which has double this width.

With the prospect of the Chard Canal in particular damaging trade on the Parrett, four traders from Langport including Vincent Stuckey and Walter Bagehot, who together operated a river freight business, commissioned the engineer Joseph Jones to carry out a survey for the Parrett Navigation which was then put before Parliament. It was supported by Brunel and a large quantity of documentary evidence. Objections from local landowners were handled by including clauses in the Parrett Navigation Act to ensure that surplus water would be channelled to the Long Sutton Catchwater Drain by culverts, siphons, and sluices, and the Act of Parliament was passed on 4 July 1836. The Parrett Navigation Act allowed the proprietors, of whom 25 were named, to raise £10,500 in shares and £3,300 by mortgage, with which to make improvements to the river from Burrow Bridge to Langport, to reconstruct the restrictive bridge at Langport, and to continue the improvements as far as Thorney.

Tissa Wewa (Tissamaharama), an ancient reservoir Sigiriya moat Major irrigation schemes of Sri Lanka, as evident from the earliest written records in the Mahawansa, date back to the fourth century BCE (Parker, 1881;Sri Lanka Ancient Irrigation Brohier, 1934). The purpose and determination in the construction of the irrigation systems are depicted by the words of Parakrama Bahu I, 1153–1186 CE: "Let not even a drop of rain water go to the sea without benefiting man". The Sri Lankan chronicle, the Culavamsa which was written in the Buddhist canonical language Pali, enumerates his works both as a provincial ruler in western Sri Lanka and later as the monarch of the whole country: he either built or restored 163 major tanks (reservoirs), 2,617 minor tanks, 3,910 irrigation channels, 328 stone sluices and 168 sluice blocks, besides repairing 1,969 breaches in embankments. Among the reservoirs he built was the tank at Polonnaruwa, called on account of its size the Parakrama Samudra (translation: Sea of Parakrama).

The Augustów Canal (, , ) is a cross-border canal built in the 19th century in the present-day Podlaskie Voivodeship of northeastern Poland and the Grodno Region of north-western Belarus (then the Augustów Voivodeship of the Kingdom of Poland). From the time it was first built, the canal was described by experts as a technological marvel, with numerous sluices contributing to its aesthetic appeal. It was the first summit level canal in Central Europe to provide a direct link between the two major rivers, Vistula River through the Biebrza River – a tributary of the Narew River, and the Neman River through its tributary – the Czarna Hancza River, and it provided a link with the Black Sea to the south through the Oginski Canal, Daugava River, Berezina Canal and Dnieper River. It uses a post-glacial channel depression, forming the chain of Augustów lakes, and the river valleys of the Biebrza, the Netta, the Czarna Hancza and the Neman, which made it possible to perfectly integrate the Canal with the surrounding elements of the natural environment.

Land reclamation during the Middle Ages, which closed the River Wantsum and connected the Isle of Thanet to mainland Kent, resulted in less tidal waters reaching Faversham. This led to the gradual silting up of estuaries; Faversham Creek and its tributaries have been reduced from to . To stop the creek silting up completely and making navigation impossible, a number of sluices have been installed since the 16th century. Faversham formerly held the weather record for the highest ever UK temperature (at the time) at . This was the first time the recorded temperature had ever exceeded reliably in the UK. This record had stood for nearly 16 years, but was beaten by 0.2 °C (0.4 °F) with a temperature of recorded in the Cambridge University Botanic Garden on 25 July 2019. The absolute minimum temperature of was set in January 1985. At the 2011 UK census, Faversham had a population of 19,316, an increase of 1,606 from the 2001 census. The population figures were split into Abbey (6,084), Davington Priory (2,593), St Ann's (5,268) and Watling (5,371).

The River Lea (or Lee) has a long history of use for navigation, with records indicating that the Abbot of Waltham was authorised to make improvements in 1190, and evidence for tidal gates at Bow from the reign of King Edward I, when Henry de Bedyk, the prior at Halliwell Priory and owner of the nearby tide mills, erected a structure some time before 1307. River levels were managed by flash locks or sluices, and as the volumes of traffic using the river increased, there was friction between the bargees and the millers, since use of a flash lock affected the head of water available at the adjacent mill. In 1765, the commissioners responsible for the river asked the engineer John Smeaton to survey the river and make recommendations for its improvement. Smeaton produced his report in September 1766, in which he recommended that the flash locks should be replaced by pound locks with two sets of gates, and that a number of new cuts should be built, including what became known as the Hackney Cut from Lea Bridge to Old Ford.

Several of the six classic simple machines were invented in Mesopotamia. Mesopotamians have been credited with the invention of the wheel. The wheel and axle mechanism first appeared with the potter's wheel, invented in Mesopotamia (modern Iraq) during the 5th millennium BC. This led to the invention of the wheeled vehicle in Mesopotamia during the early 4th millennium BC. Depictions of wheeled wagons found on clay tablet pictographs at the Eanna district of Uruk are dated between 3700–3500 BCE. The lever was used in the shadoof water-lifting device, the first crane machine, which appeared in Mesopotamia circa 3000 BC. and then in ancient Egyptian technology circa 2000 BC. The earliest evidence of pulleys date back to Mesopotamia in the early 2nd millennium BC. The screw, the last of the simple machines to be invented, first appeared in Mesopotamia during the Neo- Assyrian period (911-609) BC. The Assyrian King Sennacherib (704–681 BC) claims to have invented automatic sluices and to have been the first to use water screw pumps, of up to 30 tons weight, which were cast using two-part clay molds rather than by the 'lost wax' process.

Vistula valley east (upstream) of Toruń Large parts of the Vistula Basin were occupied by the Iron Age Lusatian and Przeworsk cultures in the first millennium BC. Genetic analysis indicates that there has been an unbroken genetic continuity of the inhabitants over the last 3,500 years. The Vistula Basin along with the lands of the Rhine, Danube, Elbe, and Oder came to be called Magna Germania by Roman authors of the 1st century AD. This does not imply that the inhabitants were "Germanic peoples" in the modern sense of the term; Tacitus, when describing the Venethi, Peucini and Fenni, wrote that he was not sure if he should call them Germans, since they had settlements and they fought on foot, or rather Sarmatians since they have some similar customs to them. Ptolemy, in the 2nd century AD, would describe the Vistula as the border between Germania and Sarmatia. Death of Princess Wanda, by Maksymilian Piotrowski, 1859 The Vistula river used to be connected to the Dnieper River, and thence to the Black Sea via the Augustów Canal, a technological marvel with numerous sluices contributing to its aesthetic appeal.

He was rewarded with the title of Grand Guardian of the Heir Apparent and promoted to Minister of Works, then Right Censor-in- Chief and Director of the Grand Canal (zongdu hedao 總督河道). The Director- General of the Grand Canal since 1572 to 1574, Wan Gong's solution for the Grand Canal and the Yellow River is building dyke to confine and narrow a section of the watercourse, increasing the velocity of the current ensued, the current with higher velocity would carry more silt, so that the watercourse would discharge silt into the sea. Pan endorsed and generalized that, he summarized it in eight characters: "Entraining silt with confined current by building dykes" (築堤束水, 以水攻沙 in Chinese). Pan proposed several suggestions towards the emperor of Wanli: # Fill breaches to keep the Yellow River follow its original course # Build dykes to avoid the river burst again # Repair sluices and dams to protect the Grand Canal # Build weirs to consolidate embarkment # Suspend dredging the estuary to reduce expenses # Let the proposal, recovering the defunct course of the Yellow River as a distributary to the sea, lie During the early 1580, Pan became the minister of War in Nanjing, and then the minister of Justice.
