EVACUATION SIMULATION USING RIVER INUNDATION ANALYSIS -STUDY OF VERTICAL EVACUATION BEHAVIOR AND EFFECTIVENESS OF VOLUNTARY SHELTERS-

Abstract

 Flooding caused by heavy rains has occurred in many parts of Japan and therefore it is important to encourage voluntary evacuation behavior for damage control. In this study, we examined an evacuation simulation that applies the results of river inundation analysis using iRIC, and examined the effectiveness of vertical evacuation and voluntary shelters. The simulation results show that vertical evacuation is effective, and that evacuation to voluntary shelters increases the evacuation completion rate and reduces the time to complete evacuation. By examining multiple cases of breaches, the possibility of understanding the risk of evacuation in the target river is demonstrated.
