Abstract
Sand dunes represent a sedimentary natural phenomenon formed by combining the various sediments transported by the wind resulting from the weathering and erosion processes of the various rocks of the earth and depositing them in different shapes, sizes and areas that form especially in the desert areas, so sandy dunes west of the Euphrates (study area) are part of the wind deposits that it covered large parts of Iraq, as it contributed to its formation many natural factors represented in the quality of rocks, surface nature, climate, water resources, soil and natural plant and its role in the geomorphic processes of erosion, transport, and sedimentation. Which led to major changes in the pattern of distribution of these dunes during the short period of 1972 to 2019, and thus the research aims to uncover the size of the changes that occurred in the sandy clusters west of the Euphrates between the cities of Najaf and Nasiriyah, by analyzing the satellite of the American satellite (Landsat 2 mss for 1972 and Landsat TM7 for 2019) by conducting a non-targeted classification process cover of ground to find the cover of sandy dunes, using Erdas Imagine V-9.1 and Arc Gis V-10.4 software. Carry out the analysis and calculate the areas on which these dunes were distributed spatially and temporally, and then show the size of the changes during the mentioned period, and develop the necessary solutions to limit those changes that could negatively affect the various environmental activities.
