沿岸域の高潮・洪水同時浸水災害における 避難対策と避難所の再配置に関する研究

抄録

Recently, due to continuous increase of the scale and intensity of torrential rains and typhoons, the flood risks for hinterlands of existing disaster prevention facilities are increased. To protect human lives from these events, soft measures should be implemented as well as hard measures. The purpose of this study is to understand typical inundation patterns of the Tomoe River, Shizuoka, for big typhoons with high storm surges and to propose a new method for selecting locations of evacuation shelters that effectively reduces the number of victims. With the method, new evacuation shelters which would minimize the number of victims were suggested, but it was found that early evacuation was more effective than the establishment of new evacuation shelters for this area.
