| The water became insufficient due to the increasing demand with time to industrialization, cultivation and growing population. The researching of alternate sources for clean water is becoming an essential and vital thing. The goal of this study is sharing in construction of desalination plants depending on groundwater of less salinity than sea water of coastal areas under different lithological conditions to become a piolt model for surrounding areas. Also,solving the problem face tourist villages in the transportation of the necessary water for drinking, domestic uses and construction.Three study sites (I, II, III) are existed on coastal zones at Mediterranean Sea, Suez Gulf and Aqaba Gulf, respectively. Geoelectrical resistivity sounding and 2D imaging profiles are tools uniquely suited to such objective. The results of geoelectrical data interpretation revealed the geoelectrical parameters from resistivity and thickness also, the depth to water and its direction flow. According to these information, it can be detected the best site for drilled productive groundwater wells with less salinity to supply the desalination plant and other disposal bine wells to inject saline water of resulting desalinating process. The results obtained from the interpretation led to different geoelectrical successions which are formed from a number of layers. They are grouped together in three main layers (A, B, C) at both sites (I &II) but four geoelectrical layer (A, B, C &D) at site (III). These geoelectrical successions divided into dry layers and other saturated layers. According to resistivity values the saturated layers divided into different saturated waterbearing units which are brackish, saline and more saline that affected by seawater intrusion. According to the results of this study, it can be recommended the sites of productive drill wells that recharge the desalination plants. Generally, the locations of these kinds of wells will be existed far away the shore line whereas the large thickness with low salinity and suitable depth. The other disposal well will be existed near the coastal zone in the same trend of water flow. Also, it can be drilled more than one well for large quantity water but it must be considered the distance between them and safe yield to keep the groundwater condition long time. | ||||
