Sediment transport is the process by which soil, sand, and other materials are moved from one place to another by natural forces like water, wind, and ice. This movement can occur in rivers, oceans, and even on land, shaping landscapes over time. For example, when a river flows, it can carry small particles downstream, gradually eroding the riverbanks and depositing sediment in new areas. The study of sediment transport is important for understanding how ecosystems function and how human activities impact the environment. Engineers and scientists often monitor sediment movement to manage coastal erosion, maintain waterways, and protect habitats for wildlife.
