Abstract
In the 2011 off the pacific coast of Tohoku Earthquake, coastal near cities are catastrophic damaged by Tsunami. The Tsunami sweeps away houses, ships and a lot of cars during runs up on land. The driftage car caused destruction of the structures and fire. In addition, the supply transportation network was interrupted to block a road by drifted cars. As a reason, the complex disaster is necessary to predict by using inundation and drifting simulation. In this research, it is developed that the numerical simulation model for predicting the driftage behavior during flood. And, the numerical simulation model is discussed to compare with hydraulic experiment.
