Abstract:
The study aims to study the groundwater as a scientific concept in general and focus on the study of ground water represented by wells in Thi Qar Province in particular. The study relied on the governmental data of spatial characteristics as well as the geographical distribution of the hydrological characteristics of the groundwater wells in Thi Qar governorate during the period 2010 - 2015, As well as the field study and the (40 samples of groundwater wells) represented by the dry seasons in July 2016 and wet in January 2017, for the purpose of identifying the manifestations of groundwater investment in the province of Thi Qar as well as to obtain field information on the phenomenon (groundwater) and identify the problems and access to the most important Solutions and proposals for the development and development in the province of Thi Qar.The area of the study is located in the southern part of Iraq within the sedimentary plain and extends between the widths (º32¯ - º30.33¯) north and between the longitude (°47.12¯ - °45.37¯) east, knowing that the area of the study area is (435244 km2) . In the study area, there are many geological or sedimentation deposits that date back to the triangular and quadrilateral time zones, as well as the study area within the unstable or twisted pavement that occupies a large area of the study area.The geographical distribution of groundwater wells in the study area. The study included (586 wells) for the period 2010 - 2015 in the study area, especially the administrative units (areas of Sayed Dakhil, Al Batha and Al Gharaf) as the most administrative units for wells numbers in the study area. The most abundant year for the groundwater wells in the study area, it may represent in 2012 and the (156 wells), and the government agencies (the General Authority of groundwater / Basra branch) are the most excavation wells in the study area, and the depths of wells (10 - 13m) and production wells (2.1 - 3 liters / sec) and groundwater level (3.3 - 4m) and the mobile groundwater level (7.1 - 8m) are the highest in the study area. Moreover, the type of pump (Kanzerai) was the most used and located away from the well (9.4 - 10.9.4m). The height of the wells above sea level was highest in the rise (5.1 - 6 m), which was recorded in the other rise in the study area.The discusses the spatial and temporal analysis of the Physical and chemical properties of groundwater in the study area. The Physical, chemical and other Physical ions characteristics of the groundwater in the study area varied between dry and wet Seasons on the one hand and water characteristics in the years in which some wells were drilled compared to the results of laboratory analyzes of seasons Dry and wet, on the other hand, as well as variation in the classification of groundwater in the study area according to Schuler method and Solen classification. This difference in the characteristics and classification of groundwater in the study area, to effect the natural goal of climatic conditions, and also the human factor represented by agricultural activity and the extent of the use of agricultural fertilizers and the amount of ground water withdrawn from wells in the study area.The study aspects of groundwater investment, its problems and future prospects in the study area. The most important aspect of groundwater investment in the study area is the agricultural investment in a larger proportion compared with other investments (for human consumption and for drinking animals and for construction purposes and industrial purposes) In the study area suffers from many problems, most notably the problem of salinity and the problem of pollution and the problem of Subsidence and the problem of lack of interest in wells and other problems, which leads to the development of solutions and proposals for the development and development of groundwater in the study area example rationalization in water consumption and increase groundwater recharge (water harvesting) and the use of modern technologies and improve water quality and solving the problem of salinity and the problem of pollution and maintenance of solving the problem of subsidence and interest wells, as well as proposals for solutions to another goal to develop groundwater investment in the study area.
