On-site storage facilities are an effective countermeasure for mitigating the damage caused by pluvial inundations in urban areas. In this study, we slightly modified our previously-developed integrated simulation model for pluvial inundation, and applied it to an actual urban area. We quantitatively evaluated the mitigation effects of assumed on-site storage facilities, and found that as a single strategy, on-site storage facilities with a practical scale of storage capacity could not provide sufficient mitigation. We recommend installing both on-site and off-site storage facilities widely distributed in a catchment area.
