Abstract: Submerged breakwaters are submitted to actions, that cause many times serious damages, in the stability of the structure or/and in the integrity of the blocks. The knowledge of these forces, resulting from the wave induced pressure diagrams, is, therefore, of a significant importance for its design. The variation of water pressures acting on submerged breakwater models with different characteristics was analyzed under different wave conditions (regular and irregular) on a series of two dimensional experiments carried out in the wave tank of the Hydraulics Laboratory of FEUP. The main conclusions of this work point that the upper zone of the models and, particularly, the seaward exposed edge of the crown, are the most critical sections, in terms of wave-induced pressures and loads. The roughness of the surface of the models and, namely their permeability, has shown also to affect considerably the magnitude of the pressures.
