Which outcome results when rapid sediment deposition significantly lowers the capacity of vegetated natural levees along a river?

💡 Explanation

When substantial sedimentation decreases a levee's vegetated capacity, reduced protection from overbank flow occurs because the levee loses its ability to effectively hold water during periods of high discharge, leading to flooding. Therefore, increased floodplain inundation occurs, rather than incision, stabilization, or recharge, because these require changes to flow energy or groundwater processes.
