A feasibility study on the applicability of the TDEM method in detecting sea-water intrusion into fresh-water aquifers was carried out. It was found that absolute resistivity values varying between 0,5-1,5 ohm-m are typical for sea-water intrusion. These are different from any other resistivity values which stem from other known lithology and/or water-salinity combinations. The TDEM method has proved to be a reasonable accurate technique for detection of fresh-water/sea-water interface in carbonate, and particularly, coastal aquifers.
