Water quality structures in a semi-enclosed water area are influenced by not only meteorological disturbances but also freshwater inflow from rivers. Large floods, in particular, have a great impact on ecosystem. In this paper, an atmosphere-ocean-wave-water quality coupled model was developed so that the primary production of phytoplankton, the decomposition of organic matters and the circulation of nitrogen and phosphorus can be estimated. The coupled model was applied to elucidate water quality structure in Ise Bay at the Tokai heavy rain. As a result, the model was found to be capable of reproducing water quality structure during the Tokai heavy rain. Furthermore, it was revealed that the abrupt change of the water quality structure during the Tokai heavy rain is mainly dominated by river load.
