Abstract

Abstract

In this paper,a tsunami numerical model is built.In computing the transoceanic tsunami propagation,the linear shallow-water equations are solved with leap-frog finite difference.Grid size and time step are selected in such a way that the numerical dispersion introduced by the leap-frog method is nearly the same as the frequency dispersion in Boussinesq equations.Therefore,computation time and memory are saved in the condition of notreducing the precision of tsunami computation.In the coastal transfor mation computation,the energy dissipation due to seabottom friction is included.In this model,a nested multiple grid system is developed to improve the resolution of important regions.The tsunami happened in the Taiwan Strait in 1994 is simulated by using this model.The simulation results agree with the observed ones.The model has been used to calculate the pr obable maximum tsunami(PMT) of the Fujian Hui'an Nuclear Power Plant.
