An oxbow lake is a crescent-shaped lake formed when a river meander is cut off from the main channel. This process involves erosion (cutting through the neck of the meander) and deposition (sealing off the ends of the abandoned channel).

Oxbow lakes are landforms typically found in the mature stage of a river valley, resulting from lateral erosion and deposition.

Potholes are cylindrical depressions drilled in the river bed by abrasion (erosion). Levees are natural or artificial embankments formed along the river banks by deposition of sediment. Rapids are turbulent sections of a river where the water flows rapidly over a steep gradient, primarily an erosional environment or flow characteristic rather than a depositional landform.
