Question

Quizplus · Accepted Answer

The fastest water velocity in a meandering river is on the outer side of the bend, known as a cutbank. This area experiences the greatest erosive action, which forms a steep bank. Over time, the cutbank may migrate upstream as the meander moves, leaving a curved "scar" on the riverbank. This is not to be confused with an oxbow, which is formed when a meander is cut off from the main flow of the river. A point bar is a depositional feature on the inside of the meander bend, where slower-moving water allows sediment to settle out.
