ABSTRACT: Wadi El Assiuti represents a promising area for
agricultural development and building new communities far from the
overpopulated areas in the Nile Val-ley. An integrated approach of
satellite-based data and geophysical data with borehole data was used for defining
the area of interest, the sediment thick-ness, delineating the subsurface
structures, and mapping the depth to the basement rocks, and defining the
groundwater aquifers. Findings are: 1) Dramatic changes are detected in the
anthropogenic activities at the entrance area of the wadi, making stress and
heavy exploitation of the groundwater resources. However, the central and
northeastern regions show no development; 2) Several structural trends in the
directions of NNW, NW, NE, and E-W are cutting the basement rocks and
sedimentary cover; 3) The depth to the basement rocks is increasing eastward
from ~2.24 km to ~4.84 km; 4) Three groundwater-bearing reservoirs are
represented by the shallow Qua-ternary, the fractured limestone, and the deep
Nubian sandstone aquifers; 5) The deep-seated faults are affecting the area and
rising groundwater from the deeper Nubian aquifer along its sub-vertical trend;
and 6) The results are in-formative and used to define the suitable sites for
water well drilling.
