Abstract
<p>In order to understand, in detail, the actual situation of the flood damage risk in cities caused by river flood, we focused and analyzed the "Flood Damage Area Map", in which the affected municipalities record the extent, cause, etc. of each inundated area as part of the national Statistical Survey on Flood damage. The Maps, of the areas with large numbers of damaged houses, obtained in PDF format, were converted into shape file format data to be analyzed together with the National Land Numerical Information data to investigate their characteristics of urban and geographic topography. Cases that require special response were extracted and discussed of their characteristics and the direction of countermeasures. Through the study, we have presented methods for grasping and analyzing the state of inundation by river flood, and clarified, to some extent, the characteristics of areas with high inundation risk in the urban area.</p>
