Performance comparison of wave models for large coastal areas
近岸较大区域波浪数值模型的比较

Random wave model based on approximate parabolic mild slope equation, (simulating waves nearshore) (SWAN) modified for TMA spectrum and SWAN with default JONSWAP spectrum were applied for the circular shoal experiments in the wave basin of University of Delaware. The results all agreed well with the data. SWAN gave better results at the shoal center and behind the shoal. Because nonlinear interaction was ignored in parabolic mild slope equation model, it gave higher maximum value and wave heights varied sharply in space.
