Which process limits the height of natural levees formed along a meandering river?

💡 Explanation

When a river floods, sediment deposition occurs primarily near the channel edges, forming levees because flow velocity decreases at channel margins. This process continues until levees reach roughly the floodplain elevation, preventing further preferential building. Therefore, a stable level occurs rather than indefinite growth limited solely by oxidation deposition frequency, or incision.
