主 题:numerical simulation harbor wave hazard frequency spectrum analysis
摘 要:Resonance may occur when the periods of incoming waves are close to the eigen-periods of harbor *** amplified waves by resonance in harbor will induce serious wave hazards to harbor structures and vehicles in *** traditional theoretical approaches,the eigen-periods of harbor basin with regular shapes can be *** 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 *** 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 ***,we use frequency spectrum analysis to investigate the natural frequencies from the data recorded at the synthetic observation stations.
