PREDICTION OF CHANGES IN FLOOD RISK FOR RAILWAY NETWORKS DUE TO CLIMATE CHANGE

Abstract

 There has been growing concern in recent years about the intensification and frequency of natural disasters due to climate change. The impact of natural disasters is significant on railways. Thus, it is an urgent issue to promote measures against flood damage based on the impact of climate change on transportation networks. This research aims to assess the current and future flood risk of railroads in Japan, by applying three evaluation indices "hazard," "exposure," and "vulnerability. According to the findings, the flood risk at the end of the twenty-first century will increase a little in the sustainable scenario and increase a lot in the fossil fuel-dependent scenario compared to the end of the twenty century.
