Abstract
In the stratified closed water systems, the unique phenomena caused by the density differences are observed. Numerical simulation is useful tool for investigating such phenomena. In this paper, a three-dimensional numerical model which is based on the Body Fitted Coordinates is constructed for the purpose of calculating incompressible density current under the influence of complicated ground shape. The model is cross-checked by the results of an experiment of density front migration in a stratified closed water system. Then the model simulates wind driven density flow which causes aosio phenomenon. As a result, availability of our model is confirmed and the simulation result of wind driven density flow gives important information.
