![]() ![]() This increase may be due to the dense formations, which change vertically from alluvial at the surface to compacted sediments and then to sandstone at depth. This represents the gradual increase of seismic velocity layers with depth. The thickness of the top saturated zone ranges between 9.5 m and 26 m. ![]() The estimated thickness of the unsaturated zone varies between 1 m and 3.5 m. The second and third velocity ranges may show water level at saturated zone and the lithologic interfaces. The obtained results showed that, the first low velocity range may indicate an unsaturated zone, which is directly affected by surface water, that appears along the studied area. ![]() ![]() The seismic primary wave velocity distribution indicated that, there are three different zones ranging between (500-625 m/s), (1300-1600 m/s) and (2400-3000 m/s). The well logging measurements included: natural gamma-ray (GR), self potential (SP), electric resistivity (16″, 64″), density and neutron. Eight seismic refraction profiles, five Vertical Electrical Soundings (VES) and four geophysical well logging tools were acquired along the western side of Gulf of Suez, Egypt, in order to study the aquifer's geometry, groundwater level and locate promising sites for future drilling. ![]()
