GENERATION OF RIVER LEVEE DATA IN THE LOWER REACHES OF TYPICAL INTERNATIONAL RIVERS AND ITS EFFECTS -Focused on Elbe and Rhine rivers-

Abstract

 Global warming is predicted to result in extreme climatic changes, such as sea-level rise, tropical cyclone activation, and increased precipitation, which could cause water-related disasters. Therefore, the risk of flood disasters in coastal countries is increasing. Consequently, it is crucial to make accurate damage predictions and implement adaptive measures. Herein, reserach has been conducted to compile global levee data and assess the damages to enhance the accuracy of imundation simulations for storm surges. During the study, it was realized that the run-up of storm surges into rivers was an important factor that had to be considered. Therefore, in this study, we created river levee data for international rivers indicating various regions globally, we also verified the effectiveness of this data.
