Abstract

 An important measure for rebuilding risk-conscious and well-prepared society against water-related disasters is to make and improve flood hazard maps that can promote residents’ evacuation behavior. This study addresses the limitation of current hazard maps which assume maximum-scale rainfall for promoting residents’ understanding of flood disaster and voluntary evacuation. In order to overcome this limitation, it proposed “zoning-hazard map” which shows flooding conditions by zone. It then examined the effect of proposed map through an experiment targeting residents living in Nomura district at Seiyo-city in Ehime prefecture. The result showed that residents tended more to understand relevant conditions of flood disaster through reading the new type of flood hazard map than through an ordinary hazard map. The map was also shown to have an indirect effect on their judgment for evacuation through promoting their understanding of flood disaster.
