The use of geophysics prospection in hydrogeology is widely used as a way to find groundwater under difficult hydrogeologic potential rocks. The porphyric rocks lay- ered in the northern part of Beja city, are the most unproductive regional aquifer. Usu- ally this aquifer has an upper layer of 5 to 15 meters deep of weathered rock and a second layer build by fractures rock till 30 metres deep.
