The study of groundwater potential in Wadi El-Assiuoti is of a prime importance for both current and future
development. In this paper the groundwater occurrences are investigated using integrated; 1) geophysical well
logging (Self potential, Resistivity and Gamma Ray), 2) subsurface lithologic data and 3) hydraulic data
(transmissivity, transmissibility, hydraulic conductivity and storativity) in addition to reviewing all studies on
Wadi El-Assiuoti. Different petrophysical parameters (formation water resistivity, formation factor, porosity,
permeability, salinity and shale volume) are computed. These parameters are very necessary to identify the
aquifers characteristics in the surveyed area. The integration between geophysical and hydrogeological data
shows the possibility of two water bearing formation (Quaternary and Plio-Pleistocene). Generally, porosity and
permeability values of these aquifers decrease toward the west. The aquifers exist under unconfined to semi
confined conditions. The wide range values of both well efficiency and hydraulic conductivity indicate heterogeneity
in the lithology and hydraulic characteristics of the aquifer materials. The computed transmissibility
values indicate that the water-bearing sediments in the area under investigation are generally of high productivity.
In some localities due to the heterogeneity of sediment, the water-bearing sediments are of moderate
productivity. Recently, due to the increase of drilling activities at the middle part of the studied area some
problems concerning the groundwater potential and high salinity in the area are happening.
