Wave dissipating works using concrete blocks has been widely used for reducing the wave overtopping rate. In general, wave over topping rate is calculated by using Goda’s diagram. However, it is pointed that the calculated value is quite different when the profile of wave-dissipating works change caused by the damage of wave-dissipating concrete blocks. The aim of this study is to investigate the effects of deformation of wave-dissipating works on the overtopping rate. Several cross sections of wave-dissipating works defined based on the previous study. When the crown of wave-dissipating works down to near the still water level, the overtopping rate increases with progress of wave-dissipating works deformation. When the crown of wave-dissipating works settles under the still water level, the increase of overtopping rate is suppressed.
