"WebAt the same time, it drops sediment, which contains particles of rock and sand, on the inner bank in a process called deposition. This causes the meanders to become grow bigger and bigger over time. Eventually the river may take a short cut, cutting across the narrow neck of the loop, leaving a separated U-shaped lake known as an oxbow. " - Explain how meanders change over time
