1-D and 3-D inversions of VES data were successfully used to outline the shallow freshwater zone at Zawyet El Hawala site, northwestern coast of Egypt, and to determine the lateral and vertical extensions of this freshwater body. The freshwater zone shows a minimum thickness of about 7 m at the northern side of the study area toward Mediterranean Sea and a maximum thickness of about 20 m at the southern part. The effect of sea water, in the form of low resistivity structure, was firstly appeared at 7.5 m bgs in the northern part and it was extended southward with increasing depth until it covered the whole area at about 30 m bgs. The most proper sites for drilling water well are the locations of VES6 or VES9 as they show relatively high resistivity values (low salinity) until 20 m bgs. The pumping from the proposed well should be limited not to raise the saline water table at the well site. Excessive rainfall and surface runoff during the heavy rain season can be collected in man-made outlined trenches to be used for irrigation purposes during the dry season.
