Resonance may occur when the periods of incoming waves are close to the eigen-periods of harbor basin. The amplified waves by resonance in harbor will induce serious wave hazards to harbor structures and vehicles in it. Through traditional theoretical approaches, the eigen-periods of harbor basin with regular shapes can be obtained. In our study, we proposed a numerical model to simulate the behavior characteristics of the harbor waves. A finite difference numerical model based on the shallow water equations (SWE) is developed to simulate incoming tsunami and tidal waves. By analyzing the time series data of water surface wave amplitude variations at selected synthetic observation locations, we estimate the wave height and arrival time in coastal area. Furthermore, we use frequency spectrum analysis to investigate the natural frequencies from the data recorded at the synthetic observation stations.
