This thesis studied the effects of land cover changes on hydroclimatic extreme events in the Senegal River Basin. It analyzed the evolution of these events from 1982 to 2021 using eight extreme precipitation and discharge indices, along with statistical trend and homogeneity tests. The results reveal an increase in extreme events. The WRF-Hydro model was calibrated and validated, showing good performance, particularly for the reference year 2018. Finally, the conversion of savannah into wooded savannah shows a measurable impact on moderate and extreme floods. These findings provide essential insights for sustainable water management and improved adaptation to climate change.
