Quantitative Characteristics of Groundwater and its Distribution in Tal-Afar Region- Iraq

The current research aims to know the quantitative characteristics of groundwater and its spatial distribution in Tal Afar district. It was relied on a set of data related to groundwater. All of them were entered into the GIS environment for the purpose of performing digital manipulations and drawing out maps. It was found that the depth of the groundwater ranges between (0-519) m, the stable groundwater level is within (0-89) m, and the variable groundwater level is (0-165) m. And the amount of decrease in the wells was within (0-146.4) m, and the productivity of these wells ranged between (37.28-0) L/sec, and the amount of conductivity was between (1345-0) m2 / day, and the productivity of water springs spread in the study area It was within (0-1000) L / sec. The study showed that the distribution and direction of the wells are from the northwest to the southeast of the study area and its standard distance covered 61.5% of the wells data, and the direction of the wells distribution was 120 towards the north in an oval shape that included approximately 66.76% of the data entered wells.
