Sediment transport is the movement of particles, such as sand, gravel, and silt, by water, wind, or ice. This process plays a crucial role in shaping landscapes, building or eroding coastlines, and influencing ecosystems. Researchers in this field study the mechanisms and patterns of sediment transport, as well as its impact on various natural systems. They investigate factors such as grain size, flow velocity, and sediment composition to better understand and predict how sediment is transported and deposited in different environments. Studies in sediment transport can have important implications for managing water resources, coastal protection, and ecological restoration.
