Abstract
Characteristic beach profile change has been observed at the beach with integrated shore protection system by large scale submerged breakwater, jetties and nourishment. In this study the cause of characteristic beach profile change was presumed. Two-dimensional hydraulic model test with movable bed was carried out to verify the presumed result. Through the model test, it was found that the cause of constant shoreline erosion is land subsidence, the beach erosion by storm surges in winter is accumulated because sand transport onshore is not occurred in calm, the flat profile is formed at the depth equal to transferred wave height by submerged breakwater.
