| Outline of Final Research Achievements |
1. A new algorithm which calculates river width from a water body map was developed. The developed algorithm was applied to the global satellite water body map, and the “Global Width Database for Large Rivers: GWD-LR” was constructed. The GWD-LR is the first global-scale satellite-based river width product. The constructed database is distributed and applied to multi-dicipline studies such as flood simulation, biodiversity, and water resources assessment.
2. The “Global 3-second Water Body Map: G3WBM” was developed using 33,890 Landsat images. The G3WBM is the first global high-resolution water body map which considers the frequency of water existence. The G3WBM was used to improve the accuracy of river width calculation in this project. In addition, the developed database was distributed to and used by many researchers working on various topics such as aquatic ecosystem, flood risk assessment, and malaria projection.
