Abstract

Recently, the serious hazard dueto heavy rain occurs frequently. Especially, lower region of urban area where many people live receives flooddisaster. In urban area, the flow and distributionof inundation water are affected by various urban structures. Therefore, for the establishment of countermeasures for the flood disaster in urban area, the influence of urban facilities on inundationwater behaviormust be considered. Inthis study, the detailed inundation analysis including sewer system inurban area is developed and the validityof this analysis model is discussed by comparison between simulation results and observed data in Tokai heavyrainfall in 2000. Moreover, applications of the presented analysis model to measures for flood disaster are examined. This study treatsfour examinations, effect of sewer system, overflow weir ofstorm water and inflow situation into manhole on inundation situation, and also distribution of backflow sewage water from manhole. From this analysis, effective information for measures of flood disaster and the various applications of inundation analysis are shown.
