Impacts of upstream water abstraction and climate variability on River Mpanga hydropower production in Uganda

摘要

Abstract We investigated impacts of water abstraction and climate variability on Mpanga hydropower. Flow exceedance probabilities over hydrologically wet and dry conditions were compared. Hydropower productions with and without water abstraction were compared. Capacity of the hydropower plant on River Mpanga is 18 Megawatts which can be produced with the river flow of 16 m3/s. The differences in means of daily flows over the periods 2000–2013 and 2014–2020 considering exceedance probability selected in the range 20–50% were found to be significant (p?
