| Abstract | In the present study different geophysical techniques such as Vertical Electrical Sounding, Gravity and Magnetic are used to delineate the deep aquifer in the South El-Egma area. The area under study is located in the central part of Sinai Peninsula, Egypt. In this area eighteen deep vertical electrical soundings have been carried out, using current electrode spacing (AB) ranging from 10 m to 6000 m to reach the deep aquifer in the study area. The results of resistivity interpretation indicate that; the study area consists of five geoelectric units. The fifth geoelectric unit represents the main groundwater aquifer in the study area (Nubian Sandstone). The depth of the upper surface of the Nubian sandstone aquifer was ranging from 718 m to 927 m, resistivity varies between 26.5 Ohm.m and 477 Ohm.m and the thickness ranges from 191 m to 3330 m. Five hundred and twenty-one gravity stations have been collected by using CG-3 Gravity-meter. The results of quantitative interpretation for gravity data revealed that, the area was dissected by different normal fault elements of trends NE-SW and N-S. Four hundred and eighty-seven magnetic measurements were done to detect the basement depth and then the thickness of sedimentary deposits. The results of magnetic method reflected that, the depth of basement was ranging from 1005 m to 4108 m. The present study aims to exploration the groundwater and assessment of the Nubian sandstone aquifer in Central Sinai, Egypt by using geoelectrical, gravity and magnetic data, where the people who live in central Sinai suffer from scarcity of water for domestic and agricultural purpose |
