This paper describes numerical and physical model tests on wave forces induced by the waves on rubble mound breakwater crown walls. The 2D hydraulic model tests are carried out in a medium scale random wave flume. The numerical code is the widely used two-dimensional RANS model IH2VOF. The objective of the research is to further verify if IH2VOF is able to provide reasonable estimates of the wave forces on the crown wall. Dedicated tests are carried out to carefully validate the model and to seek for approximate methods/correction coefficients, to eventually improve the numerical results in these difficult hydrodynamic conditions.
