ECONOMICAL ASSESSMENT OF FLOOD CONTROL MEASURES FOR ADAPTATION USING ENSEMBLE CLIMATE PREDICTION DATASET

Abstract

 Regarding the adaptation strategies for climate change, non-structural measures take priority and revision of flood control plan carried out in foreign countries is under consideration in Japan.In this study, we confirmed the validity of estimating the flood volume after climate change progressing by using dynamical downscaling data of database for Policy Decision making for Future climate change in the Class A river located in Hokkaido.In addition, we suggested the method for making flood control plan appropriately by analyzing damage reduction using different types of countermeasures and evaluating their effects from an economic standpoint including excess floods caused by climate change.
