Satellite remote sensing and GIS-based multi-criteria analysis for assessing the groundwater recharge potential zones in the Regueb basin (central Tunisia)

The groundwater constitutes the major water resource in the Regueb region, which is one of the most important agricultural areas in Central Tunisia. Regueb has an arid climate with minimal amounts of precipitation that result in insignificant natural recharge of its aquifer compared to the overexploitation of groundwater for agricultural activities. This study aims to map groundwater recharge areas across the Regueb basin using remote sensing …
