Since , the Nubian Sandstone aquifer situated between the Toshka and Abu Simbel areas of Egypt underwent intensive drilling and development as part of a land reclamation project. Drilling information was used to conduct a variety of studies regarding the hydrogeological setting of the area's aquifer.

In Egypt, the strata of major hydrogeological interest are composed of a sandstone complex ranging from Cambrian to Upper Cretaceous in age. This sandstone complex, commonly known as the Nubian Sandstone, has a thickness varying from less than m to more than m and rests directly on Precambrian by: The Formation of the lower Cretaceous sandstone (Nubian sandstone) is the main deep groundwater reservoir in Sinai that most development programs depend on, due to many reasons including its extent, its large storage capacity for groundwater and the quality of the water it contains (somewhat good) (Water Resources Research Institute and Japan.
The Nubian Sandstone probably shares a common intake area with the overlying Judea Group aquifer in Sinai and in the western section of the Dead Sea catchment area. The interrelationship between. Chapter 4 Hydrogeological setting 26 4 Hydrogeological setting Nubian Sandstone Aquifer System Extension and boundaries The Nubian Sandstone Aquifer System (NSAS) is considered to be one of the most significant and potable groundwater basins in the world, as it is the only water resource for most of the areas sharing its valuable reserve.
Abstract. THE manner of formation of the famous Nubian sand-stone has been a matter for controversy for a century. This may be partly attributed to its wide geographical distribution (extending over 30° of longitude and 20° of latitude) 1, its great vertical range (ranging from Palæozoic to Mesozoic), lack of fossils in its greater part, Cited by: The “Programme for the Development of a Regional Strategy for the Utilisation of the Nubian Sandstone Aquifer System (NSAS)” is funded by the International Fund for Agricultural Development (IFAD).

ISMAIL MAHMOUD EL RAMLY Recent results from the hydrogeological and geochemical investigations undertaken exploitation of the extensive Nubian Sandstone artesian aquifers in the Western Desert of Egypt (Dakhla and Kharga Oases) showed.
Formation. The Nubian Sandstone ranges in age from the Cambrian to Upper Cretaceous eras. Positioning of the paleoequator and paleolatitude at 20° S was derived from paleomagnetic data showing the Nubian was originally deposited in the paleoequatorial to subequatorial zone.
These paleomagnetic results corroborated previous studies suggesting that north Africa did not shift in latitude from to. The Nubian Sandstone aquifer in the central and northern Negev, Israel: delineation of the hydrogeological model under conditions of scarce data.

In South Sudan it is largely overlain by unconsolidated deposits, Border countries: Sudan, Ethiopia, Kenya, Uganda, the Democratic Republic of the Congo, the Central African Republic. Lack of hydrogeological data is the main reason for the difficulty of groundwater management, especially in arid zones.
Egypt’s Sahara Desert is located in Western Egypt and is lacking hydrogeological data. Recent development of the Egyptian Sahara is mainly due to the Nubian Sandstone Aquifer System (NSAS) as a unique source of water by: 1.
The Nubian sandstone aquifer is the only water source for domestic use and irrigation in the Kharga oasis, Egypt. In this study, 46 pumping tests are analyzed to estimate the transmissivity of the aquifer and to derive a spatial distribution map by geostatistical analysis and kriging interpolation.
The resulting transmissivity values are log-normally distributed and spatially correlated over a Author: Mustafa El-Rawy, Florimond De Smedt.

Müller, Dengler, Leicht The Nubian Sandstone Aquifer System 3 Geology • Nubian Sandstone = flat lying to gently dipping rocks • Made up of continental sediments including sandstones, grits, mudstones and conglomerates, overlain by alluvial deposits • Sandstone beds with minor intercalations of siltstone and kaolintic sandstone • Nubian File Size: KB.

5 B. Hydrogeological System3 Because of the geology of the region, The Nubian Sandstone Aquifer System is divided into two different parts (Figure 3).
The greatest and oldest part is the Nubian Aquifer System (NAS) which is unconfined. The other part is the Post Nubian Aquifer System (PNAS) which lies under Libya and Egypt.
