| dc.description.abstract | The present study area is located in Rift Valley drainage basin, in the central part of the country. Meki and Kater drainage Sub-basins of Lake Zeway have been identified for the present study. The main objective of the present study was to identify potential Small Hydropower sites in the study area and to carry out ground verification with engineering geological appraisal, at pre-feasibility level, for selected sites. In total 49 potential SHP sites has been identified during the present study. Out of these, 19 sites fall within Meki sub-basin and 30 in Kater sub-basin. Most of these identified sites are concentrated along the margin of the sub-basins. For the potential sites the 10 daily observed discharge data has been projected from adjacent gauged stations by percent area ratio method for those which demonstrate similar catchment characteristic, based on statistical regression analysis. Initial estimation of the power potential of 49 SHP sites has been computed for 75% dependable discharge and taking turbine efficiency to be 90% and efficiency of the generator as 95%. The head losses caused by the frictions and bends in the penstock have been taken equal to 10% of the gross hydraulic head. Thus, the total power potential, as estimated for 49 identified sites for which discharge data was available, comes out to be around 17 MW. Thus, these 49 potential SHP sites can be ground verified and be taken up for detailed Engineering Geological Appraisal. However, for the present study, with the limitation of resources, time and financial constraints it was not possible to undertake ground verification and detailed engineering geological appraisal of all 49 SHP sites. Therefore, a sincere effort has been made to select 3 potential SHP site namely; Rufael, Weldia and Lebu to undertake ground verification and engineering geological appraisal, at prefeasibility level. These sites were ground verified for the availability of the head, discharge, the possible layout and turbine selection. Further, engineering geological appraisal of these sites has also been carried out at prefeasibility level. Finally based on the results and finding of the present study, certain recommendations has been made.
