Summary

Report on testing of water overflow on Dutch levees. On the Dutch part of the levee in Hedwige-Prosperpolder, 11 overflow tests have been conducted. Overflow tests on levees are designed to test the strength of levees and levee covers under the load of a continuously overflowing discharge of water. For this purpose, Flanders Hydraulics Research have designed and built an Overflow Generator (Vercruysse et al., 2022) within the framework of the Polder2C’s project. This device allows to generate a controlled and homogenous discharge of water over the levee crest. Within the Polder2C’s project, 27 overflow tests on 11 Belgian and 11 Dutch levee stretches have been executed in 3 episodes from 30/10/20 to 28/11/20, 17/02/21 to 31/03/21 and 16/11/21 to 20/12/21. Different test goals have been addressed, to understand the normal performance of a levee cover, and the influence of different anomalies and/or deviations from the ‘standard’ levee.
