津波シミュレーション技術の現状と今後の展開

抄録

This paper, first of all, explains a two-dimensional depth-integrated tsunami flow model, which is often used in practice. The validity and utility of the model were examined by applying the model to tsunami induced by The 2011 Tohoku Earthquake. Furthermore, this study expounds a three-dimensional fluid analysis model “DOLPHIN” that can calculate solid-gas-liquid multiphase flow, as well as a visualization system of tsunami simulation using a three-dimensional numerical tool “OpenFOAM”, which provides dynamic information so as to enable to intuitively understand the characteristics and risks of the disaster.
