ESTIMATION OF INUNDATION AREA AND DAMAGE ASSESSMENT FOR COASTAL AREAS IN EAST AND SOUTHEAST ASIA - Based on Coastal and River Levee Data -

Abstract

 Global warming is expected to cause more severe water-related disasters, such as sea level rise, increased precipitation, and activation of tropical cyclones. Therefore, countries located in coastal areas are concerned about the increase in flood damage, and at the same time, it is desirable to take adaptive measures based on accurate inundation damage prediction results. In response to these issues, the authors have developed a global levee data set and have been assessing flood damage using this data. However, the effectiveness of levee data for coastal areas of multiple countries has not yet been verified nor has inundation damage been assessed. In this study, we evaluated storm surge inundation damage using levee data for the entire coastal areas of East and Southeast Asia. As a result, we confirmed the effectiveness of levee data for a wide area and summarized the amount of inundation damage for each administrative district in the countries in East and Southeast Asia.
