The CADMAS-SURF, which was developed by Coastal Development Institute of Technology (CDIT), has prominent feature in its versatility, and has been applied to many problems on coastal engineering. Since a long duration of wave incidence are required for random wave calculations, the computational time using the CADMAS-SURF increases drastically and it seems to be practical problem. The gradual increase of the mean water level is also reported. To overcome these problems, a new method, which combines the CADMAS-SURF and Boundary Element Method (BEM), is presented. The validity of the combined model is confirmed by comparing numerical results with theoretical ones for wave propagations of Stokes' 5th order waves and random waves.
