A floodplain (or floodplain) is a generally flat area of land next to a river or stream. It stretches from the banks of the river to the outer edges of the valley.

Where are floodplains most often found?

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.

Are floodplains found in the upper course?

Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. ... Lower course river features include wide flat-bottomed valleys, floodplains and deltas.
