Abstract: The attenuation of regular waves at different semi-submerged vertical seawalls was studied experimentally. The transmission, reflection and dissipation rates respec- tively for various wave parameters and degrees of obstruction were deduced from an energy equilibrium at the structures. It was proved that the dissipation of the initial wave energy can be extended when the semi -submerged breakwater is de- signed as a pervious wall. The most noticeable result of the investigation is that the rate of dissipation of the initial wave energy is not significantly influenced by the type of construction (perforated or slotted obstacle) when the relative void ratios and perviousness of the structures are equal.
