Time Domain Electromagnetic (TDEM) survey was carried out in the Mediterranean coast of Tunisia (Nabeul Hammamet), in order to delineate the salt water intrusion into coastal fresh water aquifer detected by drilling wells. The survey was also carried out to determine the geometry of the fresh water aquifer and to identify the continuity between the aquifer system of Nabeul-Hammamet and the bordering aquifer system on the northern side (coastal aquifer of Korba). One dimensional interpretation of the TDEM data was correlated to existing data of borehole Logs (Gamma Ray, Spontaneous Potential, Resistivity). The results indicate that TDEM survey was able to map the interface between fresh and salt water, and estimate depth of the basement when sitting new monitoring wells.

Abstract

Time Domain Electromagnetic (TDEM) survey was carried out in the Mediterranean coast of Tunisia (Nabeul Hammamet), in order to delineate the salt water intrusion into coastal fresh water aquifer detected by drilling wells. The survey was also carried out to determine the geometry of the fresh water aquifer and to identify the continuity between the aquifer system of Nabeul-Hammamet and the bordering aquifer system on the northern side (coastal aquifer of Korba). One dimensional interpretation of the TDEM data was correlated to existing data of borehole Logs (Gamma Ray, Spontaneous Potential, Resistivity). The results indicate that TDEM survey was able to map the interface between fresh and salt water, and estimate depth of the basement when sitting new monitoring wells.
