Floodwall
Extracted from the Wikipedia article Flood wall.
Floodwalls are nowadays mainly constructed from pre-fabricated concrete elements. Floodwalls often have coupures, which are large openings to provide passage of traffic except during periods of flooding, when they are closed. As a floodwalls mostly consist of relatively short elements compared to dikes, the connections between the elements are critical to prevent the failure of the floodwall.
