Hydrogeophysical investigation at El-Hammam area, North Western Desert, Egypt

El Hammam area is situated in the North-Western Coast and it is one of the most challenging regions for sustainable development. Transient Electro-Magnetic (TEM) survey has been applied for distinguishing the groundwater aquifers at the study area. Eighteen (TEM) stations were measured and interpreted to evaluate the subsurface aquifers. The final models were used for the construction of a number of cross-sections showing the vertical and lateral distribution of the geoelectrical parameters. The results of the quantitative interpretation indicate that the subsurface sequence consists of four geoelectrical units where the aquifers are represented by the second, third, and fourth layers. The hydrochemical analyses for collected samples included the determination of total dissolved solids (TDS), hydrogen ion (pH), electric conductivity (EC) and indicate that the salinity of the groundwater in El Hammam area increases with depth
