Maeslantkering

The Maeslantkering is a large movable storm surge barrier near Rotterdam, Netherlands, designed to protect the city from flooding caused by high water levels in the North Sea. When extreme weather or high tides threaten, giant gates close across the Nieuwe Waterweg channel, effectively sealing off the harbor entrance. These gates are made of massive steel and are driven by sophisticated automation to ensure quick and secure closure. The barrier is part of the Netherlands’ flood defense system, combining engineering innovation and environmental management to prevent flooding while allowing normal navigation and water flow during calm conditions.
