The Impact of Multi-Rifting Forces on the Groundwater Occurrences in Intracratonic Basins: Case Study Wadi Arab

Numbers of Paleozoic and Cretaceous intracratonic basins are recorded in Northeast Africa that are formed related multi-rifting forces. High rainfall and/or large water bodies in and/or near it causes accumulation of groundwater with good potentialities. Wadi Arab Basin southeast Egypt has selected for testing their impacts. It depends on huge data sets of topography, satellite images, TRMM, geomorphology, morphometric analyses, geology, structure, geophysics, hydrogeology, field observations and measurements, sediment and water samples, chemical analyses, ARC-MAP Program, and softwares. Muti-rifing forces led to the presence of three morphotectonic depressions in the basin with huge thickness reach 1400 m south Gebal Dahmit. Investigations of data sets reveal new information about subsurface geology and discovering four high potential aquifers belonging Cretaceous and Paleozoic with fresh and brackish water quality. They recharged from Lake Nasser through deep faults and occasionally from watershed areas. Deep groundwater wells were recommended for evolution the groundwater aquifers. Results could potentially highlight for rising fresh water demands for sustainable development in similar tectonic and hydrologic settings.
