Abstract
The major part of the Dutch flood defence system consists of dikes. One of the main failure mechanisms of dikes is wave overtopping. Waves that overtop the dike crest, run down on the landward slope and cause erosion on landward side of the dike cover. Once the cover is eroded, the dike core material starts to erode resulting in weakening of the dike which may result in a dike breach. Dike covers typically contain many transitions in roughness (e.g. from grass to asphalt; Fig. 1). Also, changes in slope angle are classified as transitions. Experiments and numerical simulations identified transitions as weak spots resulting in a local increase of dike cover erosion (Bomers et al, 2018). We want to investigate the sensitivity of various transitions in dike cover for erosion due to overtopping waves
