Abstract: Wave overtopping and the propagation of the waves on the crest and the landward side of a coastal dike is investigated numerically in this study. Wave overtopping conditions are simulated using the concept of the Wave Overtopping Simulator (WOS). Τhe computed results are compared against proposed empirical relationships based on available field measurements. The RANS equations, a turbulence model of the k-ε type and the VOF method are solved numerically, using the CFD code FLUENT, for “tracking” the free surface and the head of the “current” from the dike crest to the toe of the landward dike slope. The latter as well as the crest are usually covered by grass and its effect on the wave propagation over the crest and the landward slope is investigated.
