Contribution à l'étude géophysique d'une nappe profonde dans la région de Gabes (Sud Tunisien)
Contribution to the geophysical study of a deep water table in the Gabes area (South of Tunisia)

2 CRDA-AREE, Gabès, Tunisie
The area of study, located in the northern part of Gabes (South of Tunisia), remains other slightly unknown as far as its deep water table is concerned. The sole existing witness is the 'El Hicha' drilling, dug more than 20 years ago, reaching the water table having a salinity of 5.6 g/l at a depth exceeding 100 m. On the other hand, 15 km North West of this point, another drilling 'Sbih' has reached a water table, with a salinity of 17 g/l at a depth exceeding 150 m.
A geophysics study undertaken by VES is deemed necessary in order to know the limits of this deep water table at 'El Hicha' area. To reach this objective, a measuring study was done in collaboration with CRDA-Gabes. Results have allowed to locate the deep water table in three suitable zones to plant new drilling for exploration.
