Abstract

At Beppu port (Kitahama area 1), where Satohama creation is underway with considerations of protection against the high tide, utilization of the seashore, and the environment, a double parapet seawall for both utilization and protective effects was planned. For a double parapet seawall, vertical wave-dissipating blocks and a permeable layer structure for drainage were employed. To evaluate the multiple functions of protection for overtopping waves, (Super Roller Flume for Computer Aided Design of Maritime Structures) and a physical model were conducted. The calculated overtopping flow of CADMAS-SURF matched with that of the simulation model through CADMAS-SURF, and therefore the applicability of the physical model was confirmed. Since the physical model is often performed for representative cross- sections, reflecting the results of the physical model for parameter adjustment in the CADMAS-SURF computation resulted in improving the reliability of examinations of other parts of cross-sectional dimensions, and therefore enabled the omission of Unneeded cases in the physical model.
