Natural land has been disturbed by human activities in most of the places in the world, so has been the major issue Nepal. Hydropowers are one of the most affected services due to land use change in upland catchment. This study has tried to quantify basin flow and sediment yield due to land use changes and consequent effect on hydropower production and its revenue. In this study possible future land use change scenarios for conversion of forest, agriculture and barren land were developed by past trends. Hydrological model SWAT was developed for the simulating land use change scenarios. Model result for flow then simulated in reservoir simulation model, Hec-ResSim to obtained power output. Power outputs and revenue for scenarios were compared with the present cases.
