Firstly, necessary information and data were selected to estimate "micro-hydropower potential" of rivers and canals and methods were examined to correct the information and data. Continuously, it was developed an estimation approach to "micro-hydropower potential" using GIS data (alignment of water channels, grid elevation dataset and catchment geographical information) and flow-rate information (discharge and/or intake volume). Furthermore, it was examined to minimize information and data for applying the potential estimation, and to confirm an approach to calculate a distribution of small-hydropower potential on channels in large drainage basin, as a "small-hydropower potential Map" preparation approach. A part of research results was able to be applied to nationwide small-hydropower potential estimation by Ministry of the Environment.
