Fundamental Study on Flood Waste Estimation in the Anticipated Inundation Area of the Kinugawa River: Housing and Building Flood Damages

Abstract

In recent years, extreme weather events have been more frequent due to climate change and the influence of global warming. Consequently, flood and soil erosion have caused serious damage in various places. It is difficult to accurately predict the timing and magnitude of such flooding events. Therefore, limited progress has been made regarding safety measures to be taken in preparation for flooding. Once a disaster occurs, a delay in initial action can cause a variety of problems that require extensive recovery time and a delay in reconstruction. This study estimates the different types of disaster waste that could result from flooding in the anticipated inundation area of the Kinugawa River, with a particular focus on waste from housing and buildings. Varying situations and rainfall information related to concerned municipalities were also taken into account. The results of this study point out disaster waste caused by potential floods in the Kinugawa River under various situations. It is hoped that the method of this study can be used as a prediction tool.
