| Abstract: | A numerical hydrodynamic model is described for the simulation of storm surges in Bangladesh. The model applies to a region including the river Meghna and allows account to be taken of the freshwater discharge through the river. By using a forcing wind stress distribution representative of the 1970 Chittagong cyclone, a comparison is made between model simulations both with and without inclusion of the river along the Bangladesh coast. The conclusion is that the introduction of the effect of a river in storm surge models may lead to an important change in the detailed prediction. |
