Abstract
<p> There are few previous studies of storm surge simulation using a non-hydrostatic model, and the applicability of the model has not been obvious sufficiently. In this study, we carried out inundation simulations around Nagoya port due to storm surge caused by a potential maximum typhoon using hydrostatic and non-hydrostatic models. It was found that there is little difference between the numerical results obtained from hydrostatic and non-hydrostatic models. Hydrostatic model is, therefore, judged to be suitable for storm surge-induced inundation analysis from the viewpoints of calculation accuracy and efficiency. The difference in velocity field in runup area was also confirmed by the division number of vertical mesh, and the attention should be paid to the influence of vertical mesh division on numerical results.</p>
