Abstract
The huge tsunami caused by the Great Tohoku Earthquake devastated the coastal area on March 11, 2011. It is important to review disaster prevention and reduction of the coastal regions. In this study, 3D tsunami simulation by a SPH method, which is one of the meshless particle analysis, is developed to accurately estimate tsunami inundate zone and to assess the fluid force acting on coastal structures. In addition, a high resolution geography modeling technique for particle simulation has been proposed. The modeling technique converts from randomly distributed point group data given by aerial survey and bathymetry to particle simulation model. Finally, efficiency and adequacy of the proposed simulation technique has been validated through an application to one of the harbor city Taro in Iwate prefecture.
