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 .
7-652: 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 . 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
14-706: 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 floods and can no longer be recognised on maps. At
21-594: Is a canal that was constructed in 1904 to be a branch of the river Maas (French: Meuse) in the Dutch province of North Brabant . The Maas splits near Heusden into the Afgedamde Maas and the Bergse Maas. The Afgedamde Maas flows north until its confluence with the river Waal (the main distributary of the river Rhine ) to form the Merwede , while the Bergse Maas continues west as the main distributary of
28-549: The Maas was at the same time dammed-up and renamed Afgedamde Maas ("Dammed-up Meuse"). The resulting separation of the rivers Rhine and Maas reduced the risk of flooding and is considered to be the greatest achievement in Dutch hydraulic engineering before the completion of the Zuiderzee Works and Delta Works . There are two road bridges and three car ferries. The latter are free of charge for all traffic, as promised to
35-630: The Maas. Part of the Merwede (the Nieuwe Merwede ) rejoins the Bergse Maas to form the Hollands Diep estuary. Historically, a natural branch of the Maas flowed from Heusden to the Amer and Hollands Diep estuary; this branch silted up and now forms a stream called Oude Maasje . The Bergse Maas, which takes its name from the town of Geertruidenberg , was constructed in its basin to take over its functions, in 1904. The other main distributary of
42-463: 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 . 51°42′00″N 4°35′02″E / 51.70000°N 4.58389°E / 51.70000; 4.58389 Bergse Maas river The Bergsche Maas ( Dutch pronunciation: [ˈbɛr(ə)xsə ˈmaːs] ; current spelling : Bergsche Maas )
49-915: The 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
