Groundwater recharge rate for weathered rock aquifers in the Sahel of West Africa are sparse due to insufficient knowledge of the recharge pathways. This study was initiated in the Tougou ephemeral river catchment (37 km2) to improve understanding of recharge pathways to a weathered rock aquifer in the dryland of Burkina Faso. It is based on field investigations conducted in 2016–2020 on a piezometric transect and large-diameter wells, perpendicular and longitudinal to the river, respectively. Geophysical measurements, lithologs analysis, permeability tests, measurements of groundwater electrical conductivity and temperature, groundwater and river level monitoring, and rainfall measurements were undertaken. The results showed a laterally co...
