The main aim of this minor thesis is to evaluate if we can accurately predict the mean wave overtopping discharge in rubble mound breakwaters with the tools we currently have. In first place, the available methods (Eurotop formulas and improvements proposed by some authors, Lykke Andersen and Burcharth formula and Neural Networks), are critically assessed focussing on how the berm influence is described. In second place, a new numerical tool called SWASH will be tested.
