As behavior of tsunami inundation is varied by local topography and arrangement of buildings, high-resolution topographic data with several meters interval is required for accurate tsunami inundation simulation. However, the accuracy of tsunami simulation with high-resolution data is not examined enough yet. In order to verify the accuracy of tsunami simulation with high-resolution topographic data, basic hydraulic experimental results are compared with numerical results. Although reproduction of tsunami inundation behavior around structure is difficult by use of shallow water equation, the suitable spatial grid size for the tsunami prediction is able to be determined by Δx⁄√ghmaxT.
