Haringvlietdam

The Haring Vliet dam is the sixth building in the Dutch Delta Works. He concludes with a number of large locks the Haring Vliet, a seeartig widened estuary waters of the Rhine, and is between Voorne -Putten in the north and Goeree -Overflakkee in the south.

Data to the dam

The widest estuary of the Rhine, the Nieuwe Merwede, and the Meuse reach after their confluence on the Haringvliet the North Sea. Through a system of 17 per 62 meters wide locks the river water is discharged into the North Sea at low tide, is left whereas at high tide salt water of the North Sea only to a small, precisely controlled extent in this coastal inland waters. Every year, so get about 30 billion cubic meters of river water into the North Sea, representing a mean flow ( MQ ) of around 950 m³ / s. If the water levels of the Rhine when entering the Netherlands ( Lobith ) below 1,100 m³ / s, the locks are closed, so then the combined water of the Nieuwe Merwede and Maas waterways Dordtsche Kil and Noord reached the New Waterway through Rotterdam and here ensures sufficient water. If at Lobith flow against more than 9000 m³ / s, the locks remain fully open, and the vast majority of the effluent from the river system of the Rhine reached via the Haringvliet locks the sea.

The dam is 5 km long and 56 meters wide. About the causeway leads the four-lane highway N 57, as part of the dam route connects the province of Zeeland with Rotterdam and thus the province of South Holland.

Construction work

In November 1958 started the construction work. A total of 21,800 piles were driven into the ground. Then in 1961, the locks were built, and from 1966 the dam was built. Here, use was, as already during the construction of Grevelingendams, the cable railway technology. 1970 Haringvlietdam was finished. It was opened by Dutch Queen Juliana on 15 November.
