← GeographyWhich consequence results when levee armoring fails under erosion?
A)Increased channel bed sediment transport
B)Accelerated downstream floodplain sedimentation✓
C)Decreased river sinuosity and braiding
D)Diminished aquifer recharge rates nearby
💡 Explanation
Accelerated downstream sedimentation happens, because levee armoring failure activates increased bank erosion during flood events caused by hydraulic action. A larger sediment load is transported downstream, therefore the floodplain sedimentation rate increases, rather than channel bed transport, impacting channel morphology changes.
