Short summary
Runoff simulation is complex in poorly gauged and data-scarce hydrosystems of the West African Sahel. The results of this study showed that multi-sites calibration without nested sub-catchments is the best modelling scheme for capturing the hydrological response of the Sahelian catchments. This approach could therefore be applied to obtain regionalized parameter values for the West African Sahel region from small catchments distributed across all climatic zones.
