Question

major features of a floodplain​

Answer 1

Explanation:

The major features of a floodplain include meanders, point bar, oxbow lakes, natural levees, backswamp, and streams. A stream flowing around a meander bend erodes the outside curve and deposits sediment on the inside curve to form a point bar. The meander bend migrates laterally and is ultimately cut off, to form an oxbow lake. Natural levees build up the banks of the stream, and backswamp develop on the lower surfaces of the floodplain. Yazoo streams have difficulty entering the main stream because of the high natural levees, and thus flow parallel to it for considerable distances before becoming tributaries. Slope retreat continues to widen the low valley, which is partly filled with river sediment

Answer 2

Expert Answer:

• As a river enters a plain, it twists and turns forming large bends or meanders. ...
• Floodplains are formed when rivers overflow and soil gets deposited on the river banks. ...
• When a river approaches the sea, its speed decreases and it breaks into a number of streams known as distributaries
