The main objective of the paper is to compare the results of numerical simulations of the wave overtopping over a smooth impermeable sea dike. Four different numerical models have been used. One model, ODIFLOCS, is a one-dimensional model based on the non-linear shallow water equations. The three other models, VOFbreak2, SKYLLA and 2D-HYDROTUR, are two-dimensional models based on the Navier-Stokes equations and the Volume-Of-Fluid (VOF) method for treating the free surface configuration. Physical model data of the sea dike, including measurements of layer thickness, discharge, cumulative overtopping volume and average overtopping rate, have been used as validation reference data. The numerical results from the four models are presented and compared with particular attention to the average overtopping rates. Recommendations are given for further improvements of the numerical simulation.
