| Outline of Final Research Achievements |
The purpose of this study is to detect water-related diasters earlier and contribute to prevention and mitigation of water-related disasters by using satellite remote sensing. Satellite rainfall map is compared with Japan Meterological Agency's rain gauge data, and it is found that estimates lower than 20 mm/h is basically reliable, but those higher than 20 mm/h are likely to be overestimated. Modified satellite rainfall map is successfully applied to detect heavy rainfall with the return period of 50 years or higher. Moreover, mapping of inundation area by using microwave radiometers and simulation of water resources with high spatial resolution in Kyushu Island are done in this study. These results will be applied to other regions than Japan and are expected to contribute to mitigation of water-related disasters.
