| Abstract: | By using both two-dimensional nonlinear storm surge mode1 and water level model comprising the nonlinear interaction of tides with storm surges (T-S),the nonlinear T-S interaction in Shanghai coastal region for eight storm surge process indueed by the tropical cyclone of different tracks are numerically analysed in this paper. It is shown that a substantial improvement to the numerical simulation of the set-up and water level will be acheived when the nonlinear T-S interaction is taken into account.The nonlinear bottom friction plays an most important role in controlling the nonlinear T-S interaction and both nonlinear shallow water and momentum advection terms contribute considerably to the nonlinear T-S interaction as well. |
