Abstract: The protection of coastal structures is important to South Africa. The dynamics of breakwaters is a topic that is becoming amenable to numerical study, in terms of the motion of multiple interlocking structures under wave action. In this preliminary study, plunging waves and the loads they exert on semi-submerged structures are investigated with a Reynolds-Averaged Navier-Stokes model using a Volume of Fluid approach to surface modelling. Qualitative comparison of wave properties with experimental observations, including turbulence in surging and plunging waves, is encouraging, but quantitative comparisons are still to be made. Loads on a semi-submerged beam are modelled in preparation for studies of the dolos geometry
