A geoelectrical resistivity measurement utilizing the Schlumberger array was made at the Bir Madkour area in the southern part of Wadi Araba, Aqaba Province, Jordan, in order to evaluate the groundwater potential in the area and to provide information on the thickness, lithology, and tectonics of the subsurface layers. Twenty-five vertical electrical soundings (VES) were conducted by BGR resistivity instrument in 2000. The AB/2 spacings for VES were taken at 900 m. The data obtained were interpreted by using the classical matching curves and computer modeling techniques. Interpretation of 25 sounding curves indicates that in the Bir Madkour area there are three groups of resistivity values above the basement rocks. These three groups of resistivity values correspond to three geological layers. The groundwater level possible is to coincide with the contact between the alluvial sediments and the Upper Cretaceous rocks. Its depth varies between 70 m and 110 m.
