Question

Quizplus · Accepted Answer

The portion of each meandering curve subject to the fastest water velocity forms a cutback, which is a steep area where the water is eroding the outer edge of the curve. This cutback can eventually cause the river to abandon the meander loop and form an oxbow. Point bars form on the inside of meander loops where sediment is deposited as the water slows down. Meander scars are remnants of abandoned meander loops.
