How does river meandering impact sediment transport and deposition?
River meandering significantly affects sediment transport and deposition due to its changing flow velocities and curved paths. On the outer bends of meanders, the faster-flowing water increases the river’s capacity to erode and transport sediments.
This results in the erosion of riverbanks and the transportation of sediment downstream. Conversely, on the inner bends where flow velocities are slower, sediment is deposited, forming features like point bars and sandbanks.
Over time, this process creates a dynamic equilibrium between erosion and deposition. The sediment transported and deposited influences riverbed morphology, floodplain soil fertility, and overall sediment distribution patterns, which can impact land use and river management strategies.
