Which outcome occurs when a river's levees erode?

💡 Explanation

Floodplain sedimentation increases because the eroded levees reduce the channel's capacity to contain floodwaters, therefore, more sediment is deposited over the wider floodplain, rather than the sediment being conveyed further downstream within the channel.
