Assessing the Impact of Management Options on Water Allocation in River Mubuku-Sebwe Sub-Catchments of Lake Edward-George Basin, Western Uganda

Limited studies in East Africa and particularly Uganda have been carried out to determine map water use demands. This study aimed at assessing the impact of management options on sustainable allocation environmentally sensitive catchments Mubuku Sebwe Lake Edward-George basin Western Uganda. We used hydro-meteorological data analysis techniques quantify available water. applied Mike Hydro model allocate different ongoing developments catchment based 2015 2040 demand scenarios. Nile Basin Decision Support System assess sustainability scenarios for resources use. Reliability computation did not consider hydropower this study. Results show that was 60 MCM/YR 365 Mubuku, respectively is projected decrease by 15% 11% year under climate scenario RCP8.5. project rise 64% domestic, 44% livestock, 400% industry, 45% hydro power 66% irrigation 2040. increase from 5.2 MCM 10.7 fall 364.8 329.8 per annum. 9.7 22.2 its 52 annum 2015. Water managers ought reliable which prioritizes domestic environmental demands, allocates 90% industrial demand, 70% 60% livestock demand. recommend institutionalizing guide Mubuku-Sebwe sub catchments. users should employ more efficient achieve high reliability management.
