Question

Where we find extensive floodplain?​

Answer 1

Answer:

Floodplains are most commonly found near the mouth of a large river, such as the Rhine, the Nile, or the Mississippi, where there are occasional floods and the river usually carries a large amount of sediment.

Answer 2

Floodplains are perhaps the most common of fluvial features in that they are usually found along every major river and in most large tributary valleys. Floodplains can be defined topographically as relatively flat surfaces that stand adjacent to river channels and occupy much of the area constituting valley bottoms.
