広域３次元津波シミュレーションにおける造波境界の設定方法

抄録

We proposed to take several wave boundaries which make possible multi-way incident into three dimensional analytical boundary and then we made three dimensional tsunami analysis over wide area based on the result of two dimensional analysis. By this proposed technique, the propagation movement of two dimensional tsunami was reflected in three dimensional analysis boundary, and the continuous generation of the tsunami simulation that comprised a macroscopic evaluation of the tsunami and a microscopic evaluation in the vicinity of the site could be shown. This analysis of the continuous generation of tsunami can be expected as a technique to be able to achieve the flood simulation in high accuracy as well as being able to make the evaluation of the power of tsunami load that affects on embankments, bridges, and buildings.
