This flood barrier protects the polders beyond from flooding in the event of an inordinately high water-level without, however, impairing the tidal ebb and flow. It consists of a lift gate in two steel curtains spanning 80 metres slung between lifting towers, and a bridge across the river. The arch-form of the twin curtains can handle a difference in level of 4.5 m.
