high gradient, and a narrow and shallow channel with no floodplain

Alluvium (consists of sand, gravel, silt, clay, and gravel, as well as other organic matters) mantlings or coverings are usually developed in the lower part of the river with the formation of floodplains and deltas.  They may also be deposited at lakes or river banks.  Headwater streams deliver nutrients and other organic materials (e.g. fallen leaves) to downstream regions to sustain downstream aquatic life.
