Vivari Channel in Albania links Lake Butrint with the Straits of Corfu. In physical geography and hydrology, a channel is a landform on which a relatively narrow body of water is situated, such as a river, river delta or strait. While channel typically refers to a natural formation, the cognate term canal denotes a similar artificial structure.
These channels are classified as a composite form of which the individual channel belts may have braided, meandering or straight channels. Although similar to, and even encompass other channel types, anastomosed rivers are their own entity and have just begun to be studied by geologists , revealing that much is still unknown.
Pothole – Natural bowl-shaped hollow carved into a streambed; Rapids – River section with increased velocity and turbulence; Riffle – Shallow landform in a flowing channel; River – Natural flowing freshwater stream; River delta – Silt deposition landform at the mouth of a river; River island – Exposed landmass within a river
A wide variety of river and stream channel types exist in limnology, the study of inland waters.All these can be divided into two groups by using the water-flow gradient as either low gradient channels for streams or rivers with less than two percent (2%) flow gradient, or high gradient channels for those with greater than a 2% gradient.
The Channels Natural Area Preserve is a 721-acre (2.92 km 2) Natural Area Preserve located in Washington and Russell counties, Virginia.It was established in April 2008 to protect a number of significant natural communities and habitats, including high-elevation forests, rock outcrops, and cliffs.
A canal can be constructed by dredging a channel in the bottom of an existing lake. When the channel is complete, the lake is drained and the channel becomes a new canal, serving both drainage of the surrounding polder and providing transport there. Examples include the Lage Vaart . One can also build two parallel dikes in an existing lake ...
A river is a natural flow of freshwater that flows on or through land towards another body of water downhill. [1] This flow can be into a lake, an ocean, or another river. [1] A stream refers to water that flows in a natural channel, a geographic feature that can contain flowing water. [2] A stream may also be referred to as a watercourse. [2]
The terms river morphology and its synonym stream morphology are used to describe the shapes of river channels and how they change in shape and direction over time. The morphology of a river channel is a function of a number of processes and environmental conditions, including the composition and erodibility of the bed and banks (e.g., sand, clay, bedrock); erosion comes from the power and ...
