Outline of Final Research Achievements	The goal of this study is to evaluate spatially detailed small hydropower potential for all over Japan using super high resolution distributed hydrological model in order to produce useful information to consider regional and basin scale applications as well as county scale. The head of flued (elevation drops) was calculated high resolution DEMs in Fundamental Geospatial Data available from the Geospatial Information Authority of Japan (GSI). Available discharges at each points was estimated using a developed super high resolution distributed hydrological model extended from “YHyM/BTOP”. Finally, small hydropower potential was estimated from above heads and discharges. As a results, we confirmed that it was feasible to evaluate more spatially detailed and accurate small hydropower potentials using proposed method in this study.
