Which of the following is true about the formation and migration of meanders?
A)Most floodplains do not preserve evidence of the former position of meanders.
B)Flow velocity is highest when water takes a shortcut around the inside of a bend.

D)Migration of meanders back and forth can help form a floodplain.
E)None of these are correct.

Question

Quizplus · Accepted Answer

Meanders typically migrate back and forth over time, causing erosion on the outer banks and deposition on the inner banks. This process can lead to the formation of a floodplain as sediment is deposited on the inside of the bend, causing the river to shift its course over time. Choice A is incorrect because floodplains often do preserve evidence of former meanders in the form of abandoned channels or oxbow lakes. Choice B is incorrect because flow velocity is actually highest on the outside of a bend where the channel is narrower and the gradient is steeper. Choice C is incorrect because meanders migrate outward as sediment is deposited on the inside bend, not inward.
