The submerged permeable breakwater is increasingly regarded by coastal engineers for use against the beach erosion and the coastal hazard, even for the coastal ecological restoration. However, the wave transformation between a submerged breakwater and a seawall has not received much attention though the submerged structure may be located in front of a seawall in case of the Integrated Shore Protection System. Three problems are associated with the use of the submerged breakwater in front of a seawall. There are wave transformation and the water piling-up behind the submerged breakwater, and the wave run-up on the seawall. The experimental results of these three phenomena are reported in this study. Two distances between these two structures, and varied geometrics of the submerged permeable breakwaters were considered in the experiments for a seawall. Due to the wave reflection from the seawall, the significant fluctuation of the wave height behind the submerged breakwater is found. But the wave heights are much smaller than that of the incoming wave due to the wave breaks over the submerged breakwater. The piling-up of water is found behind the submerged breakwater, and where the maximum piling-up occurs about in the middle region between these two structures. It is found that the maximum height of piling-up decreases with the submergence of the breakwater. The empirical equation is presented in this paper for the relationship between the maximum piling-up and the submergence of the breakwater. The height of the wave run-up on the seawall is dependent upon the wave height behind the submerged breakwater. It is found that the maximum run-up increases with the submergence of the breakwater due to its relative larger height of the
