Abstract
In this study, numerical simulation of tsunami evacuation was conducted for the estimation of the number of casualties by tsunami within a certain area of the bay Kesennuma. The evacuees' action in the simulation was based on the potential model. Walking velocity and limit condition for evacuation under flood situation were decided by the function of the inundation height and velocity of a flow, which we had verified with the results of walking experiments in a water channel with steady flow.
Applying this simulation to the bay Kesennuma supposed the tsunami induced by the Keicho-Sanriku earthquake, we obtained the number of casualties under the various conditions such as dispositions of refuges, start time of evacuation, and blockade of roads.
