Short summary
Evapotranspiration is an integral element of the water availability estimation in tropical regions like West Africa. Climate change is projected to impact the water cycle. In this study, we evaluate the importance of AET (actual evapotranspiration) simulation for future climate impact assessments. We highlight differences if AET is or is not integrated in the model calibration. Our work contributes to the reduction of uncertainties in hydrological climate impact studies.
