The purpose of this study is to investigate wave deformation on a reef and wave overtopping characteristics around a vertical seawall by carrying out hydraulic model experiments and numerical computations with a two-dimensional numerical wave flume based on a VOF method “CADMAS-SURF”. The validity and utility of the CADMAS-SURF are, furthermore, verified by comparing with the experimental results.
The comparison of the computational and experimental results reveals that the CADMAS-SURF can reproduce well the experimental results, such as the spatial and temporal variation of free water surface on the reef and wave overtopping rate of the seawall. The results also show that the mean water level increases due to successive wave breaking on the reef and wave set-up remarkably takes place in front of the seawall. The full consideration of the influence of wave deformation is, therefore, found to be important in designing coastal revetments.
