The study entitled (groundwater west Low Alsalibat and the possibility of investing in the planning and development using remote sensing and geographic information systems GIS) to the distribution, geographic and spatial variation of groundwater in the study site as well as the study of the hydrological and qualitative characteristics of groundwater in order to find out the possibility of investing for the purpose of planning and development , the study area is located between the side of the astronomical latitudes (3051 - 2932) in the north and along the brackets (3045-1246) to the east, either administratively they are located within the boundaries of the hand Besah to spend within the Salman Al Muthanna province, it is located south low city of Nasiriyah (Salibat), which is a distance of about 45 km, an area of (756) km. (Were selected 32) wells which are distributed in the farms located within the boundaries of the study area for the purpose of quantitative study acting, production and attributed fixed and mobile and deep groundwater, showing through field survey and satellite visuals and topographic maps that the study area drainage area of a natural basin Salman namely with the topography of semi-flat to undulating container on a number of shallow valleys (Abu Ghar and Alasdair and Alkasir and Abu Goyer) with a sandy soil Loam, the region descend gradually towards the north, and the tendency of synthetic layers have the same general direction.
There are three underground reservoirs in the upper reservoir study area is confined to exist within the sand and Almtbkharcah deposits within the Quaternary, and the reservoir within the limestone Almarlah and mud for formative Euphrates and laurel, the bottom and the reservoir, one of the trapped type represents the unity of hydrological task within the limestone Almdelmth to form Dammam outstanding high porosity, as has been the hydraulic gradient and direction of groundwater flow is calculated by application of the (law Darcy using GIS) and reached gradient barotrauma groundwater values in the study area by Darcy's law (-4.22 to 1.52) towards the low Alsalibat reached values of conductivity coefficient of wells in the study area between the (374-230) (m) / day while the effective porosity of the formations wells study area ranged between (0.32-0.14) and extracted based on the geologic column of wells. The results showed physical and chemical analyzes of water samples taken from wells and springs the study area of (15) model, high physical transactions and concentrations and chemical values and this shows itself in the foot and they confined waters. The highest values (EC) (14350 -14638) Maekeromoz / cm for two seasons and dry wet in a row and the lowest values (1762-1930) Maekeromoz / cm for two seasons and dry wet respectively, while the ratio of sodium reached (Na) (1744- 1930) mg / liter for two seasons and dry wet respectively, and the lowest percentage (143-160) mg / l dry wet seasons in a row, chlorine reached the highest rate (3700-3821) mg / l dry wet seasons in a row, and the lowest percentage (605-710) mg / liters of wet and dry seasons respectively. Depending on the standard specifications (WHO, 2003) and (IQS, 1996) demonstrating that water study area validity to drink human absolutely not to drink poultry and animals, so its high salinity, and pollution of the elements of archaeological toxic Cal (Pb, Cd, Ni, Fe) and derived from Ckarah the region and the mixing of water deep water rising due to compositional situation characteristic of the area. Be water unsuitable for industrial use and for construction purposes, and so intense for Beeftha and be suitable for the cultivation of crops tolerant to high salinity of the medium as wheat and barley, especially since the water has values for the proportion of sodium adsorption (SAR) is located within the range of normal, reaching the highest value (57.57 to 61,77) during the wet and dry two periods and the lowest value (11.38 to 11.64) during the wet and dry two periods in a row
