Abstract Water scarcity already affects every continent. Egypt is currently using more water than its internal renewable resources, mainly based on Nile freshwater inflows. Water stress in Egypt is expected to further increase in the future as a result of rapid population growth. The studied area in west central Sinai aims to investigate the shallow and deep sections for groundwater exploration. Gravity and magnetic data interpretation are used to delineate subsurface structures and define the depth to the basement. The geoelectrical, geomorphological, gravity, and magnetic data were integrated to achieve the purpose of the current study. Hydrogeology and hydrochemistry were integrated to achieve the water type, water origin and water quality. the main purpose of gravity work is to emphasize the shallow and deep subsurface geologic characteristics of the studied area. the major tectonic trends derived from the regional and residual gravity maps are more or less similar, this situation suggests vertical up lift movement rather than horizontal movement, then, this area is subjected to Thick-skinned deformation rather than thin-skinned deformation. It is noticed that the depth to the basement surface is ranged between less than one km and more than 5-7 km, as exhibited in the resulted basement depth map and this map reflects several basement crests and basins with varying sizes and trends. the same techniques were applied on the magnetic methods which is completely confirmed with the gravity interpretations results. |
