Which consequence results when rapid levee construction on the Mississippi restricts floodplain access?

💡 Explanation

Reduced coastal wetland sedimentation accelerates land loss because fluvial sediment deposition decreases due to levee channelization controlling natural overbank flow. This disrupts delta-building, therefore wetlands starve for sediment, rather than receive needed deposits during natural floods.
