Which outcome would most likely occur after repeated flood events breach engineered levees along a major river?

A)Increased meander bend cutoff frequency✓

B)More rapid floodplain sediment accretion

C)Stabilized river channel sinuosity

D)Depletion of channel bed alluvium

💡 Explanation

Increased meander bend cutoff frequency would transpire because levee failure concentrates flow, which increases hydraulic shear forces along meander bends. Subsequently, enhanced erosion shortens the meander neck more quickly via channel avulsion, therefore shortening meanders significantly, rather than experiencing slower accretion behind established levees.
