大出水時における伊勢湾の海水流動の再現計算とその流動構造について

抄録

Coastal currents in Ise Bay are closely related to river inflow as well as meteorological disturbances. Particularly, large floods have a great effect on coastal currents and density structures. It is, therefore, of importance to examine flow and density structures at large floods.
This study is aimed at discussing the flow and density structures in Ise Bay at large floods from a perspective of numerical analysis. A hindcasting based on an Atmosphere-Ocean-Wave coupled model is performed using the observation data including river discharge at large floods. The validity of the coupled model is verified by comparing between the observation and computation results of coastal currents. Furthermore, the estuarine circulation and density distribution in Ise Bay at large floods are examined based on the numerical results.
