Abstract
One of the most famous problem faces the coastal agricultural area is the saline-water intrusion from sea. This study endeavors at detailing the prevailing subsurface conditions from the viewpoint of groundwater location, depth and quality. Two well-known geophysical methods have been used and applied to determine the depth of the fresh water aquifer and the saline water intrusion. The vertical electrical sounding and time-domain electromagnetic sounding have been pertained in the same 67 sites, which covers the study area. Analysis and interpretation of the obtained results reveals that, the subsurface consists of three geo-electrical layers with a gentle general slope towards the sea. The fresh water overlies saline water. It deserves mention to note that the fresh water depth varies between 0.5 and 65 m. under the ground surface. The saline water depth varies between 23 and 83 m. below the ground surface.
