Abstract

An experiment using a physical model of a coastal city was conducted to simulate tsunami and storm surge conditions which may lead to city inundation. The results of the physical experiment were compared with those from a subgrid numerical model based on the shallow water equation using the topography of the physical experiment obtained from LIDAR scanning. The experiment aims to provide a better understanding on the variation of tsunami or storm surge inundation level at different locations of the city due to the ground elevation, building arrangement, and shielding effects. The result from this experiment will serve to increase the accuracy of coastal numerical models and revise the current hazard maps and evacuation plans.
