← GeographyWhich outcome results when rapid levee consolidation occurs?
A)Increased sediment starvation downstream occurs✓
B)Enhanced lateral stream migration develops
C)Decreased floodplain biodiversity increases
D)Accelerated regional subsidence increases
💡 Explanation
Increased sediment starvation happens downstream because levee consolidation traps sediments near the channel via Sediment Bypass. This prevents channel equilibrium; therefore, sediment does not contribute to downstream land building, rather than nourishing adjacent floodplains with regular deposition.
