The choice of site for small hydro in the inaccessible tracts of Himalayan region is a difficult task by the conventional methods. This leads to a considerable loss of time and money in selecting a proper site for small hydel. In this paper an attempt has been made to use GIS and Remote Sensing technology to arrive at various alternative sites available in the study area and finally to select the most technically suitable site. The Soil Conservation Service (SCS) Curve Number (CN) method has been utilized to identify the monthly average runoff of the site. The distributed curve number technique has been used in this work.
