Ox-bow Lake
An oxbow lake is a U-shaped lake that forms when a wide meander of a river is cut off, creating a free-standing body of water. This landform is so named for its distinctive curved shape, which resembles the bow pin of an oxbow. In Australia, an oxbow lake is called a billabong, from the indigenous Wiradjuri language.
Answer:
An oxbow lake is a U-shaped body of water that was formerly a river meander.
Explanation:
The term "oxbow" refers to the U-shaped river meander or curled, twisting route. An oxbow lake develops when a meander is severed from the rest of the river.
(1) Sediments are removed off the riverbank, creating a bend, and then deposited on inside banks as a result of slower moving waters, which causes rivers to meander.
(2) The two outside banks of one or two meanders may gradually erode toward one another as river meanders become more pronounced and curved. The neck of land between the meanders gets narrower as the banks between them keep eroding.
3) The river eventually carves a new, straighter path after the neck of the meander is entirely eroded.
(4) Finally, the old meander becomes sealed off from the river channel as a result of a buildup of deposition between the river channel and the area, creating an oxbow lake.
