| Outline of Final Research Achievements |
This study developed a method to assess flood risk in data-scarce regions. The method consists of two components: a method for estimating inundation depth using flood extent information derived from remote sensing images and hydrodynamic simulations, and a method for establishing flood damage functions of agricultural crops using estimated inundation depth and flood disaster statistics. The first method is to estimate inundation depth which gives the best fit with flood extent derived from remote sensing images, and the second method is to establish flood damage functions based on inundation depth estimated by the first method and crop damage statistics. These methods showed reasonable results in the applications to lower catchments in Vietnam.
