Zuiderzee Works
The Zuiderzee Works () is a system of dams and Levee, dikes, land reclamation and water drainage work, which was the largest hydraulic engineering project undertaken by the Netherlands during the twentieth century. The project involved the damming of the Zuiderzee, a large, shallow inlet of the North Sea, and the reclamation of land in the newly enclosed water using polders. Its main purposes are to improve flood protection and create additional land for agriculture. The enormous scale of the works required the creation of a joint venture company comprising several large Dredging, dredging contractors, known as the Maatschappij tot Uitvoering van Zuiderzeewerken. The American Society of Civil Engineers declared the works, together with the Delta Works in the South-West of the Netherlands, as among the Wonders of the World#Wonders of the modern world, Seven Wonders of the Modern World. Background The Low Countries have low flat topography, with half the land area below or less t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Levee
A levee ( or ), dike (American English), dyke (British English; see American and British English spelling differences#Miscellaneous spelling differences, spelling differences), embankment, floodbank, or stop bank is an elevated ridge, natural or artificial, alongside the river banks, banks of a river, often intended to flood control, protect against flooding of the area adjoining the river. It is usually soil, earthen and often runs parallel (geometry), parallel to the course of a river in its floodplain or along low-lying coastlines. Naturally occurring levees form on river floodplains following flooding. Sediment and alluvium are deposition (geology), deposited on the banks and settle, forming a ridge that increases the river channel's capacity. Alternatively, levees can be artificially constructed from fill dirt, fill, designed to regulate water levels. In some circumstances, artificial levees can be environmental degradation, environmentally damaging. Ancient civilization ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, ). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clays develop plasticity (physics), plasticity when wet but can be hardened through Pottery#Firing, firing. Clay is the longest-known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been radiocarbon dating, dated to around 14,000 BCE, and Clay tablet, clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtration, filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often baked into brick, as an essenti ...

Wadden Sea
The Wadden Sea ( ; ; or ; ; ; ) is an intertidal zone in the southeastern part of the North Sea. It lies between the coast of northwestern continental Europe and the range of low-lying Frisian Islands, forming a shallow body of water with tidal flats and wetlands. It has a high biodiversity, biological diversity and is an important area for both breeding and migrating birds. In 2009, the Dutch and German parts of the Wadden Sea were inscribed on UNESCO's World Heritage List and the Danish part was added in June 2014.

IJssel
The IJssel (; ) is a Dutch distributary of the river Rhine that flows northward and ultimately discharges into the IJsselmeer (before the 1932 completion of the Afsluitdijk known as the Zuiderzee), a North Sea natural harbour. It more immediately flows into the east-south channel around the Flevopolder, Flevoland which is kept at 3 metres below sea level. This body of water is then pumped up into the IJsselmeer. It is sometimes called the Gelderse IJssel (; "Gueldern IJssel") to distinguish it from the Hollandse IJssel. It is in the provinces of Gelderland and Overijssel, the latter of which was named after this river. The Ancient Rome, Romans knew the river as Isala. It flows from Westervoort, on the east side of the city of Arnhem. Similar to the Nederrijn which shares its short inflow, the Pannerdens Kanaal, it is a minor discharge of the Rhine. At the fork where the Kanaal is sourced the Rhine takes the name the Waal (river), Waal. This river bifurcation, splitting-off is ...

Lelystad
Lelystad () is a Dutch Municipalities of the Netherlands, municipality and the capital city of the province of Flevoland in the central Netherlands. The city, built on reclaimed land, was founded in 1967 and was named after Cornelis Lely, who engineered the Afsluitdijk that made the reclamation possible. Lelystad is situated approximately three metres (10 feet) below sea level. History Lelystad is built on the seabed of the former Zuiderzee. About 6,500 years ago, this wetland was above high tide level and inhabited; the Netherlands have steadily subsided since. Near Lelystad at Swifterbant, the oldest human skeletons in Western Europe were discovered. Due to Floods in the Netherlands, rising water levels and storms, the peatlands were washed away, and the Lake Flevo, Lacus Flevo (in Roman times) grew to be the Almere (lake), Almere (Middle Ages) and became the Zuiderzee.
