GEOMORPHOLOGY OF SAND DUNES AND THEIR IMPACT ON HUMAN ACTIVITY IN NASIRIYAH GOVERNORATE

Abstract

Geomorphological processes prevalent in arid and semi-arid regions are detrimental as they lead to ecosystem degradation. Therefore, geomorphological studies are crucial for development projects, as they assess available resources and propose appropriate methods to combat the degradation of existing natural environmental resources. This research aims to study the geomorphology of sand dunes and their impact on human activity in Nasiriyah Governorate. Sand dunes are a widespread feature in the study area and are geomorphological formations resulting from natural and climatic conditions related to wind erosion. Given the impact of this phenomenon on human activity, the research hypothesized that natural factors play a significant role in influencing the dunes. The Nasiriyah station was used to monitor the impact of climatic elements that influence this phenomenon. The research findings revealed that sand dunes have a significant impact on human activity in the study area. This impact encompassed numerous aspects, including agricultural lands, residential areas, transportation, tourist and archaeological sites, air quality, and public health . This study comprised four sections. The first section presented the theoretical framework, the concept of sand dunes, their formation, and the factors influencing them. The second section addressed the natural characteristics of the study area. The third section examined the different types of sand dunes. The fourth section explored the impact of sand dunes and strategies for mitigating their risks. The research concluded with a set of findings and recommendations .
