In this study, the exact area of the Khuzestan sand dunes was first drawn and then classified in terms of morphology. Next, the dynamic state of the Khuzestan sand dunes was evaluated, and then the relationship between the speed and direction of the region's winds and the morphology and dynamics of the sand dunes was analyzed. The results of this study have shown that the Khuzestan Sand Dune, with an area of 2629 square kilometers, consists of various forms of sand dunes. The results of the analysis of the status of the Khuzestan Sand Dune activity have shown that about 43 percent of its area is covered by active areas, and in total, the Khuzestan Sand Dune sand dunes have moved between 1 and 55 meters under the influence of various natural and human factors during the years 2005 to 2020. Also, the results of the analysis of the winds in the region have shown that high wind speeds in some seasons, including spring, play an important role in the movement of sand dunes, and different wind directions have also caused the morphological diversity of the sand dunes in the region. Also, human activities, including the stabilization of sand dunes by vegetation, have caused sand dunes to remain stationary in many areas, despite the availability of conditions.
