Abstract
El-Qaa plain area is located in the southwestern part of Sinai Peninsula, and characterised by Tertiary and Quaternary alluvial sediments, sandstones and gypsum.
Magnetic, gravity, geoelectric resistivity, remote sensing and GIS methods were applied and integrated in this study to identify the subsurface rock sequences, water-bearing layers, shed more light on the subsurface structural trends and determine the zones of groundwater potentialities in the area under investigation.
The groundwater potentiality map was finally produced by the weighted spatial probability modeling (WSPM). This map comprises three gradational groundwater potentiality classes ranging from high to low. The high potential zones possess an area of about 1211.3 km², i. e., 17.64 % from the total area. The intermediate potential zones have an area of about 5010.3km² (72.98%), while the low potential zones have an area of about 642.9 km² (9.36%). The high groundwater potentiality zones were presented in the central western, central and central eastern parts of the study area. The graben structures are bounded by two opposite normal faults. These localities are considered as good basins for groundwater accumulation which belong to the sandstone layers, interpreted by electric data. Consequently, they can be considered as the best locations for drilling groundwater wells.
