التوزيع المكاني و الزماني للتجمعات الرملية غرب الفرات الممتدة بين مدينتي النجف و الناصرية و آثارها

Sand agglomerations represent a sedimentary natural phenomenon formed by the gathering of different sediments transported by winds resulting from the different weathering and erosion processes of the earth's rocks and their deposition in the form of different shapes, sizes and areas that are formed in particular in desert areas. It covered large parts of Iraq, as many natural factors contributed to its formation, represented by the quality of rocks, the nature of the surface, climate, water resources and soil, as well as natural vegetation and its role in the geomorphic processes of erosion, transport and sedimentation, and thus the research aims to uncover the environmental effects of those sandy agglomerations during the limited period From (1972-2019), through field study and analysis of satellite imagery of the American satellite (Landsat 2 mss for 1972 and Landsat TM7 for 2019) using the programs (Erdas Imagine V-9.1) and (Arc Gis V-10.4), and then set the necessary solutions To reduce those impacts that negatively affect the various environmental activities.
