Abstract
This study was performed to reproduce the storm surge generated by Typhoon 0416 over a large area at Seto Inland Sea by using a meteorological model and a multi-sigma coordinate ocean model and to demonstrate hereby the importance of winds over offshore and inland seas and inflow of seawater from offshore to inland sea. It was demonstrated that tidal level calculated by an Atmosphere-Ocean-Wave coupled model agrees well with the observed one at all the locations over Seto Inland Sea. Additionally, the calculations based on the conventional method using a parametric typhoon model and a usual sigma coordinate ocean model were performed to compare the results with those computed with the coupled model. As a result, it was shown that the parametric typhoon model underestimates the wind effects and the usual type sigma coordinate model overestimates the inflow of seawater from offshore, and the meteorological model and the multi-sigma coordinate ocean model are necessary to reproduce high-accurately the storm surge over a large area.
