津波浸水深の経験的予測手法

抄録

This study is intended to build the empirical model to estimate tsunami inundation depth based on the field survey data of The 2011 off the Pacific Coast of Tohoku Earthquake. Firstly, we explain the judgement model whether the objective site is in the inundation area. Secondly, the model to estimate the inundation depth is explained. Both of them are required only three variables, tsunami height at coastline, distance from coastline and ground level of an objective point. Finally, we explain the result of model validation. The model was validated by comparing predicted inundation depth to actual depth in the past tsunami and simulation results of Nankai-trough earthquake. As the result, we could confirm that model can reproduce the inundation area and inundation depth.
