Evacuation plan for flood disaster is necessary to save human life. The flood hazard map show flood area, evacuation places and routes can be confirmed by inhabitations. The timing of evacuation is very important for safe evacuation, but it is not shown in usual hazard map. In this study, the criterion for safe evacuation during flood was considered by the specific force per unit width, and evacuation timing was also discussed. The results are useful to make an evacuation plan.
