Numerical simulations of wave over topping over a smooth impermeable sea dike are carried out using VOFbreak2, a numerical model that solves the unsteady, incompressible, Navier-Stokes equations. The results from the simulations are compared with physical model data. Good agreement is obtained for the average overtopping rates. Results are very sensitive to the choice of the computational grid. More research is required on simulation of wave breaking on the dike slope and the flow in a thin layer over the dike crest.
