Geo-Environmental Assessment Of Nuweiba Area Gulf of Aqaba Egypt

Nuweiba area is subjected to severe geo-environmental hazards including flash flood and landslides. Water rock and mineral resources represent essential wealth for local inhabitants. Hence this study aims to define the natural resources and geo-environmental hazards in Nuweiba area. Geological geomorphological climatological and hydrological studies have been considered as significant tasks for that purpose. Flash flood risk has been evaluated based on the spatial integration between the morphometric and Synthetic Conservation Services (SCS). Locations of landslide hazards are defined based on weightage analysis of multi-criteria including distance to earthquakes slope aspect distance to fault lineaments density lithology distance to drainage drainage density and land use. The groundwater potential zones are delineated using different types of data comprising SAR GPR SRTM SPOT5 and geologic and topographic maps.El-Zalaga are the most risky wadis. In addition porphyry copper potential zones are defined based on the mapping of hydrothermal alteration zones and Analytical Hierarchy Process (AHP).
