This paper intends to develop a three-dimensional material transportation model which is composed of an Atmosphere-Ocean-Wave coupled model and two types of particle tracking models with water and soil particles. The model wasused to estimate seawater exchange and soil transport in Ise and Mikawa Bay areas during Tokai heavy rain. The numericalresults revealed not only the quantitative estimation of the seawater exchange among Ise Bay, Mikawa Bay and Open Sea but also the dynamic behavior of freshwater particles from rivers. Furthermore, the transportation and sedimentationof soil particles as well as flow and density structures at the head of Ise Bay were examined in detail basedon the results of numerical simulation with fine grid meshes.
