Impacts of hydro-climatic trends and upstream water management on hydropower generation at the Bagré dam

Abstract Global hydro-climatic trends are ambiguous, challenging the management of water resources. This challenge is addressed in current study by investigating impacts and upstream on hydropower generation at Bagré dam. Modified Mann–Kendall trend test, Standard Normal Homogeneity Test Pettit test were applied to some selected variables for change year detection, whereas relationship between dam management, assessed through Spearman correlation. The results revealed an annual positive all except level, lake evaporation outflow. break years observed (2002) inflow (2006) mainly due construction Ziga 2000 its 2005, respectively. also showed that declines each May (?30.36 MWh) June (?16.82 significant increase irrigation withdrawals (1.94 hm3 0.67 June). this highlighted non-linearity as none correlation coefficients (apart from turbine) very strong (>0.8). As many human activities occurred basin, further research should be focused use semi-distributed models assess water-use land-use generation.
