Sluice in Veelerveen, Groningen
Today Stichting IJkdijk (the Dike Gauge Foundation) simulated a breaking of a test dike under duress near the small town of Bellingwedde in the northern province Groningen.
The Netherlands, famously situated under the water level, is protected from the sea by 3700 kilometers (2,299 miles) of sea walls or dikes. It's unknown whether these are able to keep out strong flood tides. The test should show how the dike of 100 meters length and 6 meters height will respond to the assault of strong force of water.
