Answer:
alongside a river
Explanation:
When the wide meander is cut off from a river it creates a free standing body of water. This water body is called an oxbow lake.
A meander is a curve that is formed on a river. Meanders are primarily produced by the erosion of the river coast. When the erosion causes the formation of a water body shaped like an oxbow an oxbow lake is formed. They are generally formed on the final course of a river in the near vicinity.
