Abstract: It is widely known that the submerged breakwater can be used to protect coastal structures and control beach erosion. In this study, a semi-theoretical model based on the eigenfunction expansion method is firstly employed to describe diffraction of waves due to depth changes. Reflecting capability of four different shapes of submerged breakwaters is then estimated and compared by using the model. Both normally and obliquely incident waves are taken into consideration. An efficient and economical shape is recommended for the submerged breakwater.
