The Wadi Hodein area in the south Eastern Desert of Egypt is occupied by Neoproterozoic Pan-African (Precambrian) basement rocks including metamorphic and intrusive assemblages. The metamorphic assemblage comprises dismembered ophiolitic metamorphosed ultramafic rocks and island-arc calc-alkaline metavolcanics. On the other hand, the intrusive assemblage rocks include syn-tectonic tonalite-gran...

The analysis of drainage morphometry is usually a prerequisite to the assessment of hydrological characteristics of surface water basin. In this study, the western region of the Arabian Peninsula was selected for detailed morphometric analysis. In this region, there are a large number of drainage systems that are originated from the mountain chains of the Arabian Shield to the east and outlet i...

Based on geomorphic observations, we discuss lake-level fluctuations, alluvial deposition and river entrenchment in the Dead Sea–Wadi Araba area. The bulk of alluvium in the northern Wadi Araba was probably deposited before the Lisan period of lake transgression that started at about 70 kyears B.P. The lake reached a maximum elevation about 150 m below sea level (b.s.l.), possibly around 15 cal...

Assessment of environmental Impact was established to provide and evaluated the background picture of water quality of Wadi El-Natrun depression Lakes water. Physico-chemical characteristics (air and water temperatures, electrical conductivity (EC), total solids (TS), total dissolved solids (TDS), total suspended solids (TSS), salinity, pH, dissolved oxygen (DO), chemical oxygen demand (COD), C...

Wadi El Assiuti represents a promising area for agricultural development and building new communities far from the overpopulated areas in Nile Val-ley. An integrated approach of satellite-based data geophysical with borehole was used defining interest, sediment thick-ness, delineating subsurface structures, mapping depth to basement rocks, groundwater aquifers. Findings are: 1) Dramatic changes...

Abstract Recently, some areas are exposed to water scarcity and floods, rainwater harvesting (RWH) is a practical solution, particularly in arid semi-arid regions. The Wadi Watier basin located South Sinai, Egypt was selected identify the appropriate RWH techniques. Five alternatives were proposed: dam with reservoir, storage pond, an underground tank, wadi bed cultivation, or Jessor system. hy...

This contribution deals with new geology, petrography, and bulk-rock/mineral chemistry of the poorly studied ultramafics Wadi Ibib–Wadi Shani (WI–WS) district, South Eastern Desert, Egypt. These are dismembered ophiolitic rocks that can be subdivided into serpentinites serpentinized peridotites. Primary minerals such as olivine pyroxene absent in serpentinites, but relics them occur Pseudomorph...
