Oosterscheldekering
The Oosterscheldekering ( English: Eastern Scheldt storm surge barrier), between the islands Schouwen-Duiveland and Noord-Beveland, is the largest of the Delta Works, a series of dams and storm surge barriers, designed to protect the Netherlands from flooding from the North Sea. The construction of the Delta Works was a response to the widespread damage and loss of life in the North Sea flood of 1953. Surge barrier The second longest dam in the Delta Works, after the 10.5-kilometre-long Oesterdam, the nine-kilometre-long Oosterscheldekering (''kering'' meaning barrier) was initially designed, and partly built, as a closed dam, but after public protests, huge sluice-gate-type doors were installed in the remaining four kilometres. These doors are normally open, but can be closed under adverse weather conditions. In this way, the saltwater marine life behind the dam is preserved and fishing can continue, while the land behind the dam is safe from the water. Notable figures i ...

Oosterschelde 2023 Oosterscheldekering
The Eastern Scheldt () is a former estuary in the province of Zeeland, Netherlands, between Schouwen-Duiveland and Tholen on the north and Noord-Beveland and Zuid-Beveland on the south. It also features the largest national park in the Netherlands, founded in 2002. History During the Roman Era it was the major mouth of the Scheldt River. Before the St. Felix's Flood of 1530, it flowed north as a river from the east end of the Westerschelde, turned west a little west of Bergen op Zoom, and then west along the north edge of what is now the Verdronken Land van Reimerswaal, and after that widened into an estuary. Parts of that lost land were later reclaimed, restricting part of the connection to the Scheldt River to a narrow channel called the Kreekrak, which silted up and became unnavigable. In 1867 the Kreekrak was closed off with a railway embankment, connecting in the process the island of Zuid-Beveland to the mainland of North Brabant. From that moment on, the Oosterscheld ...

Delta Works
The Delta Works () is a series of construction projects in the southwest of the Netherlands to protect a large area of land around the Rhine–Meuse–Scheldt delta from the sea. Constructed between 1954 and 1997, the works consist of dams, sluices, Lock (water transport), locks, Levee, dykes, levees, and floodgate, storm surge barriers located in the provinces of the Netherlands, provinces of South Holland and Zeeland. The aim of the dams, sluices, and storm surge barriers was to shorten the Dutch coastline, thus reducing the number of dikes that had to be raised. Along with the Zuiderzee Works, the Delta Works have been declared one of the Seven Wonders of the Modern World by the American Society of Civil Engineers. History Due to indecision and the World War II, Second World War, little action was taken. In 1950 two small estuary mouths, the Brielse Gat near Brielle and the Botlek near Vlaardingen were dammed. After the North Sea flood of 1953, a Delta Works Commission w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Barrier
A flood barrier, surge barrier or storm surge barrier is a specific type of floodgate, designed to prevent a storm surge or spring tide from flooding the protected area behind the barrier. A surge barrier is almost always part of a larger flood protection system consisting of floodwalls, levees (also known as dikes), and other constructions and natural geographical features. Flood barrier may also refer to barriers placed around or at individual buildings to keep floodwaters from entering the buildings. Examples Delta Works The Delta Works in the Netherlands is the largest flood protection project in the world. This project consists of a number of surge barriers, the Oosterscheldekering being the largest surge barrier in the world, long. Other examples include the Maeslantkering, Haringvlietdam and the Hartelkering. Thames Barrier The Thames Barrier is the world's second largest movable flood barrier (after the Oosterscheldekering and the Haringvlietdam) and is ...

Oesterdam
The ( English: ''Oyster Dam'') is a compartmentalisation dam in The Netherlands, situated between Tholen and South Beveland in the eastern part of the Eastern Scheldt. The dam, with a length of 10.5 kilometres, is the longest structure built for the Delta Works. The Oesterdam was necessitated, like the Philipsdam, after the decision was taken to close off the Eastern Scheldt with a storm surge barrier, rather than a solid dam. For navigation of recreational boats and fishing vessels between the Scheldt–Rhine Canal and the Eastern Scheldt, the dam contains a small lock near its northern end, the . Located adjacent to the dam near its southern end are a pair of large locks, the , constructed to separate the canal's brackish water to the south from the freshwater to the north. Design background The Oesterdam was not originally part of the planned Delta Works, but rather is one of the compartmentalisation dams which became necessary when it was decided not to close off the ...

Ballast Nedam
Ballast Nedam is a Dutch-based construction and engineering company headquartered in Nieuwegein. The company resulted from the 1969 merger between Amsterdamse Ballast Maatschappij, founded in 1877, and Nederlandse Aannemingsmaatschappij, founded in 1917. Since 2015, the company has been owned by Renaissance Construction, a unit of Turkish conglomerate Rönesans Holding. History Ballast The existence of the Amsterdamsche Ballast Maatschappij can be attributed to the North Sea Canal (Noordzeekanaal), whose original operations began in 1877. Empty merchant ships going to sea obtained dune sand as ballast. In later years, the company also undertook dredging work. In the first decade of the 20th century, the company began to grow under the direction of Charles de Vilder, a paver and roadworker based in Amsterdam. Ballast evolved from a sand supplier to a construction firm, and from 1928 onwards, also operated as a concrete manufacturer. The introduction of the first labour-saving e ...

Neeltje-Jans
Neeltje Jans () is an artificial island in the Netherlands in the province of Zeeland, halfway between Noord-Beveland and Schouwen-Duiveland in the Oosterschelde. It was constructed to facilitate the construction of the Oosterscheldedam. After the construction, a fun park with attractions and other various expositions were built on the island, which are now connected to the shore through the dam. Another addition of the island is a nature reserve. The island was named after a nearby sand bank. The name of this sandbank has two possible origins: * It could be named after a boat with the name Neeltje Jans, stranded on the sandbank. Neeltje is a Dutch first name (a diminutive from Cornelia or Neelie like in Neelie Kroes). Jans is a familiar surname (meaning a son or daughter of Jan). *It could be named after a goddess of the sea, Nehalennia.

Closure Of Tidal Inlets
In Coastal engineering, coastal and environmental engineering, the closure of tidal inlets entails the deliberate prevention of the entry of seawater into inland areas through the use of Fill dirt, fill material and the construction of barriers. The aim of such closures is usually to safeguard inland regions from flooding, thereby protecting Ecology, ecological integrity and reducing potential harm to human settlements and agricultural areas. The complexity of inlet closure varies significantly with the size of the estuary involved. For smaller estuaries, which may naturally dry out at low tide, the process can be relatively straightforward. However, the management of larger estuaries demands a sophisticated blend of technical expertise, encapsulating Fluid dynamics, hydrodynamics, sediment transport, as well as mitigation of the potential Ecosystem collapse, ecological consequences of such interventions. The development of knowledge around such closures over time reflects a concer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
