For this purpose, we adopted our experimental results and our bound- ary element analysis. First, we estimated the physical unknowns for a breakwater using the experimental results obtained by a wave generator in our laboratory. Sec- ond, we applied boundary element methods (Kanoh et al. [1]) to confirm the experi- mental results and to reduce the amount of necessary experiment. In our boundary element analysis, a small amplitude of water motion was assumed and the free- surface boundary was fixed.
