The granulometry varies from clays to pebbles and the thickness of the alluvium tends to decrease near the Miocene outcrops and increases under the center of the plain.
The first zone shows relatively higher resistivity values that correlate with Jurassic strata outcrop and the second zone is characterized by low resistivity values whereas the third zone shows moderate resistivities that correlate with Plio-Quaternary alluvium.
This layer is probably composed of alluvium and indicates the probable existence of a groundwater potential.
In groundwater hydro-geophysics and in the lands having Mediterranean type of climate (dry, hot summer and cold, wet winter) alluvium basins surrounded by highlands form productive aquifers with good groundwater potentials, Al Farajat and et al (2005).
In this study, three logical phases were followed to locate productive local groundwater aquifers in alluvium sedimentary basins that are prone for recharge in the Petra region:
With these models, it is hoped they will help in locating areas consisting of alluvium basins and surrounded by highlands, and crossed by major faults.
