Abstract

       Groundwater is one of the most important sources of water that accumulate in the voids of the rocky layers and soils under the surface of the ground from the rainfall and snows falling on the surface of the earth and from running water such as streams, river and lakes it used by humans for drinking, agriculture, industry and solving many environmental problems. Groundwater investigation and exploration is being the urgent work , development in the technology have helped scientists search for a   groundwater using technical methods, including remote sensing and geographic information system, and their great role was in detecting variations on the earth's natural surface of geological, geomorphological, hydrological phenomena, vegetation, river distribution and drainage of streams, as well as in determining the natural surface elements in the earth, which contributes to the approval of the possibility of the existence of groundwater by determination of recharge areas and drainage of surface water and more rainwater infiltration areas. The satellite images and digital maps have effectively contributed to the analysis of the earth's surface phenomena such as faults, rock dams, fractures, linear structures, density of the water drainage network,  alluvial fan with vegetable cover, these all enable the experts to interpret the  earth surface  geology , geohydrology and geomorphology  phenomena to explore and production of groundwater.
