Abstract
In a typical breakwater, a parapet has been placed on the sea side to actively block the wave overtopping. Therefore, if the wave height increases, the parapet height should be high. If the parapet becomes high, the wave force is increased. If the wave force increases, the self-weight of the breakwater should be increased to secure required safety. If the self-weight increases, the ground should be reinforced, which is very difficult and costly in reality. In this study, a method to efficiently improve the stability of a breakwater by moving a parapet placed on the seaside to the harbor side was studied. Using CADMAS-SURF 2D, the wave force acting on the parapet and acting on the breakwater surface facing outer sea were calculated. Numerical results show that the maximum wave force acting on the breakwater can be reduced by more than 14% only by placing the parapet harbor side. This is because the wave force acting on the parapet has a large phase difference.
