Abstract
Torrential rainfalls over 50mm/h have been observed frequently in recent year and these rainfalls caused pluvial and fluvial floods in urban and rural areas. Evacuation of elderly person and traffic difficulties during pluvial flood in urban area are investigated here. As the inundation occurs in a short time, people have to evacuate through inundated road and avoid the traffic difficulties on their evacuation route. In this paper, this problem is discussed by using a commercial model, InfoWroks CS, of which accuracy is verified with the survey data of Osaka flood on 27, August, 2011. From the results, it can be shown the maps of walking and driving difficulties for pluvial flood.
