This paper proposes a method for evaluating flood risk at each community in a municipality to assist its disaster management personnel. The method is particularly for municipalities in a mountainous area where insufficient information is available for practical disaster management. In this method, we conducted inundation analysis for multiple patterns of rainfall and discharge using a rainfall-runoff-inundation model, and estimated the maximum inundation depth and the inundation duration, etc. Based on the estimation, we developed a “flood chart” to evaluate community flood risk, additionally considering other indicators. Moreover, we located areas requiring extra precautions due to high community flood risk as flood hot spots. |
