The purpose of this study is to investigate the effect of bottom topography and revetment configuration on wave deformation and wave overtopping characteristics around a revetment in regular or irregular wave field by conducting hydraulic model experiments and numerical computations with a CADMAS-SURF. The results revealed thatwave deformation over a reef has an effect on wave overtopping rate and a semi-circle type revetment is efficient in reducing wave overtopping rate. It was, therefore, confirmed to be important to consider the wave deformation so as to take countermeasures against wave overtopping in a coral reef sea area. The computational results also showedthat the CADMAS-SURF is a useful tool to estimate the wave overtopping rate of specially-shaped revetment over complicated bottom topography.
