what are meanders ? what are ox - bow lake
Answers
Answer:
Oxbow lake, small lake located in an abandoned meander loop of a river channel. It is generally formed as a river cuts through a meander neck to shorten its course, causes the old channel to be rapidly blocked off, and then migrates away from the lake.
Answer:
Meander:- A meander is one of a series of regular sinuous curves, bends, loops, turns, or windings in the channel of a river, stream, or other watercourse. It is also a term for walking slowly. It is produced by a stream or river swinging from side to side as it flows across its floodplain or shifts its channel within a valley.
Oxbow lake:-An oxbow lake is a lake located in an abandoned meandering channel, and hence on a floodplain. Because only two loops are involved in most cutoffs, oxbow lakes commonly have only a single direction of curvature. Shortly after cutoff takes place, the stream flows through two channels simultaneously: the old and the new.
