Analysis of hydroclimatic trends and variability and their impacts on hydropower generation in two river basins in Côte d’Ivoire (West Africa) during 1981–2017

Abstract Climate change (CC) and variability impacts on hydroelectric generation have become critical for hydropower management. The trends of inflow, outflow, reservoir water level, storage as well hydraulicity indices three main dams in Côte d’Ivoire, namely Kossou Taabo the Bandama basin Buyo Sassandra were examined during 1981–2017 their analyzed. Moreover, sensitivity to CC these was assessed using statistical analysis. results reveal that inflow is highly dependent rainfall while level influenced by which a function reservoirs management policy. Furthermore, Mann Kendall test revealed temperature potential evapotranspiration increased significantly all sub-basins precipitation shows significant upward trend only within dam catchment area. Meanwhile, greatly than probably due land use/cover change. Precipitation show strong correlation energy strongly correlated outflow (inflow) stations (except Kossou). at more sensitive affected level. In addition, power given year also total and/or previous depending plant.
