河川災害における住民の避難行動と災害外力の相関分析

抄録

There are two measures to reduce human damage resulting from a flood flow, that is, preventive public facilities as hardware-like aspect and residents' evacuation from inundation flow risk as software-like aspect. Since the former has a practical limit when the facilities are attacked by the flood flow beyond their strength, at that time the latter becomes important. From this viewpoint, we picked up six areas from the Sendai river basin affected by flood disaster at the latter half of July in 2006 and executed questionnaire survey to the residents about evacuation activities, needs of disaster information, understanding of flood hazard map and awareness to flood disaster. Moreover, we analyzed effects of disaster forces on evacuation activity. This paper showed that social cohesion played an important part in a community's ability to respond to flood disasters.
