At Sidi Abdel Hamid (Sousse-Tunisia), after having discovered an artesian superficial water-table, we undertook 31 V.E.S. of geophysical measurements. The underground is made of at least five beds. The artesian acquifer is wedged between two impermeable levels. Two faults (F1 and F2) cross the prospected zone. F1 has basculed down the South-East compartment. It represents a barrier between two parallel ground-water flows from West to East. The flow at the north of F1 may cross the sediments of Sebket-Sousse, and that could explain the high sulfure concentration at the level of P1 well (more than 40 mg/l). Geoelectric sections and maps of the acquifer have been made in order to better understand its general structure. Finally, we have made some recommandations and proposed the emplacement of a mechanical boring prospection.
