Abstract
This study investigated an application of wave dissipating blocks to reduce the wave overtopping at a joint corner between upright seawall and flare shaped seawall. A series of hydraulic experiments were conducted with using a plane basin to clear the effect of wave dissipating blocks on reducing wave overtopping at the joint corner. Furthermore, this study investigated the possibility of applying a partition wall, which is installed on the face of the flare shaped seawall, to reduce the wave overtopping instead of the application of wave dissipating blocks. The partition wall reduced the wave overtopping at the joint corner in the case of small incident wave angle. In the case of larger incident wave angle, wave dissipating blocks installed on the both side of the joint corner effectively reduced the wave overtopping.
