Australian creek, low in the dry season, carrying little water. The energetic flow of the stream had, in flood, moved finer sediment further downstream. There is a pool to lower right and a riffle to upper left of the photograph.

A stream bed or streambed is the channel bottom of a stream or river, the physical confine of the normal water flow.

- Stream bed

A stream is a continuous body of surface water flowing within the bed and banks of a channel.

- Stream

As a general rule, the bed is the part of the channel up to the normal water line, and the banks are that part above the normal water line.

- Stream bed

A stream channel is the physical confine of a stream (river) consisting of a bed and stream banks.

A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river.

A river begins at a source (or more often several sources) which is usually a watershed, drains all the streams in its drainage basin, follows a watercourse, and ends at either at a mouth or mouths which could be a confluence, river delta, etc. The water in a river is usually confined to a channel, made up of a stream bed between banks.

In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream.

The bank consists of the sides of the channel, between which the flow is confined.
