Earthquake and Tsunami Effects

The purpose of this study is to discuss design of mitigation by using coastal forest in a practical field, and to evaluate the role and effect of coastal forest. In this study, Iwanuma-Natori coast in Sendai Bay was selected as the research site. The field investigation was carried out to measure the topography inside of coastal forest and the forest condition. To evaluate the effect of coastal forest, one-dimensional numerical simulation was carried out based on the field investigation. And the effect of several plan of countermeasure including the afforestation of forest and the stabilized dune was examined and discussed for implementation in the field.
