A stream bed is the bottom (floor) of the stream.
A stream deposition occurs when, in the lower reaches, the flow of water (speed of flow) is reduced. Which is when the heavier sediment falls out and settles on the river bed.
Bed Load
The bed of the stream.
Sediment that is carried by a stream along the bottom of its channel.
Bed
It is called deposition. It occurs as friction or gravity overcomes the force of the moving water.
A stream bed is the bottom sediment layer of the stream channel which is constantly inundated with water. It is a saturated layer of sediment inhabitated by macroinvertibrates, algae, macrophytes, and microbes. The particle size of the stream bed material (fine clay vs large rock and boulders) is dependent on geologic region, size of the stream, and stream velocity. The stream bank is the adjacent sloping walls that confine the stream on either side. They are typically not wet except in times of high flows. Banks typically can grow more terrestrial vegetation such as reeds, grasses, and trees.

A wadis. penis In Arizona, it is an arroyo, or a stream.
The sediment that moves along the bed of a stream is called bedload. Bedload consists of larger particles such as sand, gravel, and boulders that are transported by rolling, sliding, or bouncing along the streambed.
