DEVELOPING A RISK ASSESSMENT SYSTEM FOR URBAN FLOOD CONTROL

Abstract

 Recently, pluvial flood disasters will increase due to the influence of climate change caused by global warming in Japan. Japan’s financial condition is not good. Due to these constraints, it is necessary to develop a method to determine the priority area for flood control. According to IPCC’s Fifth Assessment Report, Risk of climate-related impacts results from the interaction of climate-related hazards with the vulnerability and exposure of human and natural systems. In this study, we develop a method to assess the urban flood risk based on the IPCC’s risk concept, and discuss its effectiveness and limitations.
