Full textGroundwater is the main water resource for drinking, domestic, irrigation and industrial purposes in the study area as a result of limited natural fresh water. The water scarcity and shortage in Egypt due to population growth, agriculture expansion, industry development, climatic changes and water pollution lead to search about new water resources to overcome the depletion of annual individual share of water such as evaluation of groundwater in Precambrian aquifer, Southeastern Desert, Egypt. Egypt is under water scarcity due to difference between water demand and available water resources, so, we need to search and explore new water resources in Egypt, especially in Southeastern Desert of Egypt. The importance of Southeastern Desert of Egypt represents one of the famous regions for mining such as gold (El-Sukkari gold mine), ilmenite (Abu Ghuson) and other economic ores, therefore the area crowded with touristic villages and resorts parallel to the red sea coast with industrial, commercial and agricultural expansion in the area. The previous factors lead to necessity of qualitative and quantitative evaluation of groundwater resources to reduce the gap between the available water resources and water demand. Applications of remote sensing and Geographic information system techniques have been utilized to investigate the hydro-geological framework and hydrochemistry of fractured Precambrian and coastal aquifers system in Southeastern Desert of Egypt. The aim of the work is evaluation and exploration for new water resources in Southeastern Desert of Egypt dealing with groundwater properties and potentially in the Precambrian aquifer, Hafafit area, Southeastern Desert of Egypt. The groundwater potentialities of Precambrian and coastal aquifers have been studied using remote sensing, geomorphology, hydrology, hydrogeology and geophysics techniques. The groundwater properties of Precambrian and coastal aquifers have been studied using remote sensing, petrography and mineralogy and hydrochemistry techniques.The area is limited by longitudes 330 50/ - 350 45/ 00// E and latitudes 240 00/ - 250 15/ N and covering an area about 17290 Km2. The study area lies within arid desert conditions based on degree of aridity with air temperature and rainfall are variable from summer to winter. The temperature ranges from 22-36 Co with average 28 Co, The average annual rainfall ranges from 3 to 50 mm/year, some intense rainfall events (often 60mm.h-1). The average annual wind velocity is 18.7 km/hour. The intensity of evaporation is 10.1 mm/day. The mean annual relative sunshine ranges between (80-106 %) from season to another, the annual relative humidity varies between (32 % -60%) from winter to summer. In regard to geological setting of the area compose mainly of sedimentary rocks in the coastal line and Precambrian rocks to the west from the coast. The coastal plain sediments include tertiary and quaternary sediments, which classifie into paleogene sediments appear as Abu Ghuson Formation is belong to Oligocene age and Neogene sedimentsare belong to Miocene and Pliocene age include [Ranga Formation, Um Mahara Formation, Abu Dabbab Formation, Sabakha Formation, Um Gheig Formation, Samah Formation, Gabir Formation, Shagra Formation and Samady Formation]. The Precambrian rocks range from the oldest to youngest as [paragneisses and migmatites, geosynclinals metasediments, cataclastic rocks, metavolcanics, serpentinites, metagabbro-diorite complex, older granitoids, Dokhan volcanics, Hammamat group, younger gabbro, younger granitoids, dykes and plugs and alkaline ring complexes].The petrological studies include the mineralogical compositions of rock-bearing minerals that help to understand chemistry of groundwater and hydro-chemical processes such as water-rock interaction, leaching and dissolution of these minerals in groundwater
