river meanders
A meander is a naturally-occurring loop-like bend in the course of a river will wind round any obstacle, such as hard rock. Once a meander has been created it will continue, becoming accentuated by the erosive action of the river. On the outside of a bend there will be lateral corrasion, which will gradually work out sideways. On the inside of the bend there is likely to be some deposition, which will build up a flat flood plain. Meanders gradually move downstream. Sometimes they make complete loops, which when cut off, form oxbow lakes. The name comes from the winding River Maeander in Asian Turkey.
