abstract={This study assesses the hydrological dynamics of the Bandama River Basin in C?te d＊Ivoire under increasing climatic and anthropogenic pressures. Hydroclimatic series (1950每2020) of rainfall, temperature, evapotranspiration, and discharge were analyzed using statistical tests (cumulative deviation, Kruskal每Wallis, Mann每Kendall, SNHT) to identify breakpoints, trends, and spatio-temporal variability. The results reveal strong interannual variability of river discharge (CV = 74.5%) compared to rainfall (CV = 14.3%) and potential Evapotranspiration (PET) (CV = 5.5%). Significant hydro-climatic breakpoints were detected around 1970每1976 and 1994. The assessment of relative contributions using the climate elasticity method and Budyko decomposition shows the predominance of human activities (75每79%) over climatic factors (21每24%) in explaining mean discharge variations at Tiassal谷. These findings highlight that the proliferation of dams, agricultural expansion, deforestation, and urbanization are now the main drivers of hydrological alterations, outweighing the effect of climate. The study provides scientific references to support sustainable and integrated water resources management in the Bandama Basin.},
