Sand transport refers to the movement of sand particles by wind, water, or ice, playing a crucial role in shaping coastal and desert landscapes. Understanding the mechanisms of sand transport is essential for predicting changes in these environments and managing erosion and sedimentation processes effectively.
Erosion is the process by which natural forces like water, wind, and ice wear away rocks and soil, gradually transporting them from one location to another. This geological phenomenon plays a crucial role in shaping landscapes, influencing ecosystems, and impacting human activities such as agriculture and construction.
Transverse dunes are large, elongated sand formations oriented perpendicular to the prevailing wind direction, typically found in areas with abundant sand supply and unidirectional winds. These dunes form continuous ridges with a gentle windward slope and a steep leeward face, often resulting in a series of parallel ridges that can extend for kilometers.
Coastal dune systems are dynamic landforms that act as natural barriers protecting inland areas from storm surges and erosion while providing unique habitats for diverse flora and fauna. Their formation and stability are influenced by factors such as wind patterns, vegetation cover, and human activities, making them critical to coastal management and conservation efforts.
