Maeslant storm surge barrier in de Nieuwe Waterweg, The Netherlands captured by DigitalGlobe Satellite.
The Maeslant Storm Surge Barrier is located in the Nieuwe Waterweg near Hook of Holland and was built between 1991 and 1997. The structure is operated entirely automatically and, together with the Hartel Barrier and the expanded Rozenburg dyke, forms the Europoort Barrier. The Maeslant Barrier is a forward flood surge barrier, which means that it receives the full brunt of flooding from the sea and so protects the residents of the province of Zuid-Holland.
No other flood barrier in the world has larger moveable parts than the Maeslant Barrier. This part of the Delta Works can withstand a storm tide of 5 m above NAP.
