外文摘要：Hydropower(HP) is the major source of renewable energy supply in Nepal。 The current power generation is only 1% of the gross theoretical hydropower potential (84，000 MW)。 In this research， we tried to quantify the potential locations for hydropower plant (HPP) sites within Bagmati River Basin and estimate the total energy that can be generated spatially。 We used SWAT hydrological model for discharge simulation and GIS for spotting potential locations。 Then， general power equation was used to calculate the total power that can be generated from the basin area。 Potential sites having head difference of more than 10m was included for estimation of the energy。 Different criteria (for example， technical and socio-environmental constraints) were setup for locating the potential sites。 Flow duration curve (FDC) for each HPP sites were determined at different flow exceedance of discharge for determining design discharge。 First 80 potential sites were spotted after applying the technical constraints and finally 73 sites were determined as HP potential sites with gross head differences of 12m to 689m when applying the socio-environmental constraints。 These potential sites were categorized as micro hydro， small hydro， medium hydro and mega hydro and numbers of HP sites were found to be 4， 25， 35 and 9 respectively at 40% of flow exceedance。 The total energy that can be generated from the basin area were calculated by summing up all the energy that can be produced from individual potential site and calculated to be 3442。6 MW。 The results of the research can be utilized by the policy makers and developers of the renewable energy for generating HP for sustainable development and green environment。
