Haringvliet
The Haringvliet is a large inlet of the North Sea, in the province of South Holland in the Netherlands. It is an important estuary of the Rhine-Meuse delta. Near Numansdorp, the Hollands Diep splits into the Haringvliet and the Volkerak estuaries. 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. History The Haringvliet was formed as a result of the extensive flooding event of 1216, which breached the dunes of Voorne and created a deep saltwater inlet. During a second flooding event, the St. Elizabeth floods of 1421, this inlet connected to the Merwede and became an important estuary of ...

Haringvlietdam
The Haringvlietdam, incorporating the Haringvliet sluices, are hydraulic engineering structures which closed off the estuary of the Haringvliet, Netherlands, as part of the Delta Works. The structure consists of 17 sluices, several kilometres of dam and a shipping lock, and formed the sixth project of the Delta Works. The northernmost of the Delta Works, it was supposed to be finished by 1968 as the first part of the project. Building started in 1957 and was finished in 1971. Instead of damming the estuary it was decided to build sluices in order to be able to let in salt water to prevent freezing of the rivers Meuse and Rhine and to drain these rivers in case of flood. The height of the dam crest is 18.5m above Normaal Amsterdams Peil (NAP), and 17.3m above the water level in the Haringvliet. The width between piers is 56.5 metres, and the depth of the sill of the gates was partly determined by the need for ice breakers to pass through them at low tide, being fixed at 5.5 metres ...

Goeree-Overflakkee
Goeree-Overflakkee () is the southernmost river delta, delta island of the Provinces of the Netherlands, province of South Holland, Netherlands. It is separated from Voorne-Putten and Hoeksche Waard by the Haringvliet, from the mainland of North Brabant by the Volkerak, and from Schouwen-Duiveland by Lake Grevelingen. Since 2013, Goeree-Overflakkee has also been a municipality consisting, from west to east, of the former municipalities of Goedereede, Dirksland, Middelharnis, and Oostflakkee. The largest towns are Sommelsdijk, Middelharnis, Ouddorp, and Dirksland. Despite being part of the province of South Holland, the island's scenery and dialect are more closely related to Zeeland than to Holland. On the island they speak a form of Zeelandic, namely in the west and in the east. History The island was detached from the mainland when the Haringvliet formed as a result of two major flooding events. The first was in 1216, which breached the dunes of Voorne-Putten, Voorne and cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Rijn Maas Delta
The Rhine ( ) is one of the major rivers in Europe. The river begins in the Swiss canton of Graubünden in the southeastern Swiss Alps. It forms part of the Swiss-Liechtenstein border, then part of the Swiss-Austrian border. From Lake Constance downstream, it forms part of the Swiss-German border. After that the Rhine defines much of the Franco-German border. It then flows in a mostly northerly direction through the German Rhineland. Finally, the Rhine turns to flow predominantly west to enter the Netherlands, eventually emptying into the North Sea. It drains an area of 185,000 km2. Its name derives from the Gaulish ''Rēnos''. There are two German states named after the river, North Rhine-Westphalia and Rhineland-Palatinate, in addition to several districts (e.g. Rhein-Sieg). The departments of Bas-Rhin and Haut-Rhin in Alsace (France) are also named after the river. Some adjacent towns are named after it, such as Rheinau, Stein am Rhein, Rheineck, Rheinfelden (S ...

Hollands Diep
The Hollands Diep ( pre-1947 spelling: Hollandsch Diep) is a river in the Netherlands, and an estuary of the Rhine and Meuse rivers. Through the Scheldt-Rhine Canal it connects to the Scheldt river and Antwerp. The Bergse Maas river and the Nieuwe Merwede river join near Lage Zwaluwe to form the Hollands Diep. The Dordtsche Kil connects to it near Moerdijk. Near Numansdorp it splits into the Haringvliet and the Volkerak. History The Hollands Diep was formed as a result of the extensive flood of 1216, which breached the dunes of Voorne and created a deep saltwater inlet (the current Haringvliet). During a second flood, the 1421 St. Elizabeth floods, this inlet connected to the Merwede and became an important estuary of the Rhine and Meuse rivers. From that moment on, the freshwater part of the estuary (east of the Hellegatsplein) was renamed Hollands Diep. The former river Striene, that used to connect the Meuse with the Scheldt, was completely destroyed by these floo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voorne-Putten
Voorne-Putten () is an island between the North Sea, the Brielse Meer and the rivers Oude Maas, Spui and Haringvliet in the province of South Holland. Voorne-Putten consists of the two former islands Voorne (the larger, western part) and Putten (the smaller, eastern part). It used to be separated by the river Bernisse which silted up, uniting the two islands. It has 160,000 inhabitants (2008). Recently the riverbed has been dredged, and the two islands have been reformed. The North Sea coast of Voorne is a valuable nature reserve (sand dunes), even though the northern part of the area has lost much of its estuarine character with the building of the Maasvlakte, an extension of the Port of Rotterdam, in the 1960s.M.J. van der Maarel & E.

Meuse (river)
The Meuse or Maas is a major European river, rising in France and flowing through Belgium and the Netherlands before draining into the North Sea from the Rhine–Meuse–Scheldt delta. It has a total length of . History From 1301, the upper Meuse roughly marked the western border of the Holy Roman Empire with the France in the Middle Ages, Kingdom of France, after Count Henry III, Count of Bar, Henry III of Bar had to receive the western part of the County of Bar (''Barrois mouvant'') as a French fief from the hands of King Philip IV of France, Philip IV. In 1408, a Burgundian army led by John the Fearless went to the aid of John III, Duke of Bavaria, John III against the citizens of Liège, who were in open revolt. After the Battle of Othée, battle, which saw the men from Liège defeated, John ordered the drowning in the Meuse of burghers and noblemen in Liège whose loyalties he suspected. The border remained relatively stable until the annexation of the Three Bishoprics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoeksche Waard
The Hoekse Waard (; pre-1947 spelling: Hoeksche Waard) is an island between the Oude Maas, Dordtsche Kil, Hollands Diep, Haringvliet and Spui rivers in the province of South Holland in the Netherlands. The island, part of the namesake municipality of Hoeksche Waard, is a mostly agricultural region, south of the outskirts of Rotterdam. The Hoeksche Waard consists of reclaimed land (polders): after the Saint Elisabeth flood of 1421 most of the area was flooded. The land has been reclaimed gradually in the following centuries. Former municipalities The Hoeksche Waard formerly consisted of the following municipalities until these were merged on 1 January 2019: * Binnenmaas (villages Blaaksedijk, Heinenoord, Goidschalxoord, Maasdam, Mijnsheerenland, Puttershoek, Westmaas and 's-Gravendeel) * Cromstrijen (villages Klaaswaal and Numansdorp) * Korendijk (villages Goudswaard, Nieuw-Beijerland, Piershil and Zuid-Beijerland, and the island of Tiengemeten) * Oud-Beije ...

Merwede
The Merwede (; etymology uncertain, possibly derived from the Old Dutch ''merwe'' or ''merowe'', a word meaning "wide water") is the name of several connected stretches of river in the Netherlands, between the cities of Woudrichem, Dordrecht and Papendrecht. The river is part of the Rhine–Meuse–Scheldt delta and is mostly fed by the river Rhine. At first, a disconnected branch of the Meuse joins the Waal at Woudrichem to form the Boven Merwede (Upper Merwede). A few kilometers downstream it splits into the Beneden Merwede (Lower Merwede) on the right and the Nieuwe Merwede (New Merwede) on the left. All these rivers are tidal. The Nieuwe Merwede joins the Bergse Maas near Lage Zwaluwe to form the Hollands Diep estuary, and separates the Island of Dordrecht from the Biesbosch National Park. The Beneden Merwede splits into the Noord River and Oude Maas near Papendrecht. History In medieval times the name Merwede (or "Merwe" in Middle Dutch) was the name of a continuous ...

Pinniped
Pinnipeds (pronounced ), commonly known as seals, are a widely range (biology), distributed and diverse clade of carnivorous, fin-footed, semiaquatic, mostly marine mammals. They comprise the extant taxon, extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals), with 34 extant species and more than 50 extinct species described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular phylogenetics, molecular evidence supports them as a monophyletic group (descended from one ancestor). Pinnipeds belong to the suborder Caniformia of the order Carnivora; their closest living relatives are musteloids (Mustelidae, weasels, Procyonidae, raccoons, skunks and red pandas), having diverged about 50 million years ago. Seals range in size from the and Baikal seal to the and southern elephant seal. Several species exhibit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
