Creek in Perisher Ski Resort, Australia
Stream in Southbury, US
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 riparian zone or riparian area is the interface between land and a river or stream.

- Riparian zone

The biological habitat in the immediate vicinity of a stream is called a riparian zone.

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

The organisms in the riparian zone respond to changes in river channel location and patterns of flow.

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.

Riparian zones occur along upland and lowland river and stream beds.

Groundwater is naturally replenished by surface water from precipitation, streams, and rivers when this recharge reaches the water table.

Hyporheic zones (the mixing zone of streamwater and groundwater) and riparian zones are examples of ecotones largely or totally dependent on groundwater.
