Which outcome occurs when floodplain sediment supply decreases?

💡 Explanation

Oxbow lake development slows because Lateral Accretion depends on sediment deposition to form point bars, therefore reducing sediment slows meander cutoff; rather than expanding the flood plain or dramatically increasing levee size, which respond to peak flows, or straightening the river.
