The Oosterscheldekering (Eastern Scheldt Barrier) is the largest and best known of the Delta Works (a series of dams and storm surge barriers, designed to protect the Netherlands from flooding from the North Sea). The barrier is a 9 km long structure which seals off the Oosterschelde if there is a threat of flooding. The Oosterscheldekering Barrier connects the islands of Schouwen-Duiveland and Noord-Beveland in the province of Zeeland and was built between 1976 and 1986. It is the largest storm surge barrier in the Netherlands. The Oosterscheldekering has 65 colossal pillars, separated by sluice gates that are roughly 42 meters wide and 6 to 12 meters high, each weighing between 260 and 480 tonnes. It is designed to withstand a flood that is statistically unlikely to occur more than once in 4,000 years. The barrier will be closed if the water level of the North Sea is predicted to rise to more than 3 meters above “Normal Amsterdam Level”. At the press of a button, all 62 sluice gates are lowered and it takes 82 minutes for them all to close completely.
