Abstract: This paper presents the methodology and procedure for risk assessment and zoning of flood damage caused by heavy rainfall based on the “macro-zonation concept” in which regional macro-information such as meteorological triggering factor, natural and socioeconomic factors contributing to flood damage generating, and historical flood damages etc. is considered. In this study, Yamaguchi Prefecture in Japan is selected and its flood damage risk caused by heavy rainfall is assessed and zoned based on statistical data related to maro information.
