Recently, some coastal circulation models, e.g. Princeton Ocean Model (POM), Regional Ocean Modeling System (ROMS), etc. are applied to the storm surge simulations for enabling more accurate estimations. Among these existing models, Finite Volume Coastal Ocean Model (FVCOM) developed by Chen et al. (2003) has an advantage in that it employs unstructured grid system so as to compute tidal currents in complicated inner bays with high accuracy. In this study, for the purpose of understanding the applicability of the model to numerical simulations of storm surge inundation, numerical simulations of storm surge in the innermost part of the Ariake Sea were performed. First, a computational mesh with high spatial resolution was created, and the roughness factors on the surface of land were determined considering the land-use classification. Next, the numerical simulations were performed including the river discharges and the astronomical tides. The simulation results show that the numerical model with unstructured grids is sufficiently effective for numerical simulations of storm surge inundation.
