The Delta Works Dutch: Deltawerken are a series of constructions built between 1950 and 1997 in the southwest of the Netherlands, to protect a large area of land around the Rhine-Meuse-Scheldt delta from the sea. The works consist of dams, sluices, locks, dikes, and storm surge barriers. Along with the Zuiderzee Works, they have been declared one of the Seven Wonders of the Modern World by the American Society of Civil Engineers.
