ABSTRACT: In this
study, Ten Time Domain Electromagnetic (TDEM) measuring points have been
conducted at four pre-selected sites along Wadi Deir Al-Kahaf in order to
investigate the potential of the near subsurface deposits and aquifer for
groundwater artificial recharge applications. The surveyed results suggest well
resolved geological layers such as alluvial mudflat, basalt layers and their
saturation states. In addition a hydrogeophysical cross section along the
studied sites was constructed which permits to locate the lateral variations in
rock properties due to water saturation and or facies changes. The saturated
thickness of the Upper Aquifer System in the study area was found to be changed
from 5 m near TEM 1 to about 120 m near TEM 4 in thickness. The Abed Basalt
Aquifer (AOB) has an average saturation thickness of about ~60 m, and forming
the main aquifer (~100 m thickness) near surface to the north of the study
area. TEM-3 and TEM-4 sites were found to be potential sites for groundwater
artificial recharge based on the constructed hydro-geophysical model. This
study recommends implementing detailed geophysical investigations particularly
in the most northern parts of the study area.
