Channel (geography) - Wikipedia
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.
River channel types: straight, meandering, braided, anastomosing
2023年4月12日 · The river channel is shaped by the surrounding landscape, underlying rock type(s), sediment availability, and flow regime (i.e., variation in the amount of water flowing through a river, including the magnitude and frequency of different size floods).
Channel types - Wikipedia
Low gradient channels of rivers and streams can be divided into braided rivers, wandering rivers, single thread sinuous rivers (meandering), and anastomosing rivers. The channel type developed depends on stream gradient, riparian vegetation and sediment supply.
River morphology - Wikipedia
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 consistency of the current, and can effect the formation of the river's path.
Types of River Channels - The Science of Rivers
2019年11月11日 · First, there is the river that forms its channel, its watercourse, by means of erosion of the earth’s surface. Rivers concentrate the flow of water from rain or from melting snow or ice and this flow is a force, a source of energy, which can excavate the soil or even carve its way into bedrock, forming the channel.
River channel patterns: Braided, meandering, and straight
Channel pattern is used to describe the plan view of a reach of river as seen from an airplane, and includes meandering, braiding, or relatively straight channels. Natural channels characteristically exhibit alternating pools or deep reaches and riffles or …
Types of river channel patterns and their natural controls
1998年5月1日 · River channel patterns are thought to form a morphological continuum. This continuum is two-dimensional, defined by plan features of which there are three (straight, meandering, branching), and structural levels of fluvial relief of which there are also three (floodplain, flood channel, low-water channel).
5.5: The Morphology of Rivers - Geosciences LibreTexts
2021年12月26日 · The river channel itself can be characterized most fundamentally by its cross-section shape and cross-section area. The width is the distance, normal to the local trend of the river, from bank to bank; obviously the width depends strongly on the river stage as well as on the average size of the river.
River Channel Types on the Landscape — The Science of Rivers
2020年6月6日 · Idealized landscape, showing sequence of river channel types. Channel form is related to position in the landscape, which governs the dominant sediment movement processes. Adapted from FISRWG (10/1998), Stream Corridor Restoration
River vs Channel: Are They the Same Thing? - A-Z Animals
2022年4月18日 · River vs Channel Explained. These are the similarities and differences between a river and a channel: A river is a channel, but a channel isn’t necessarily a river. Both rivers and channels have banks and beds. Channels and rivers both flow in one direction. Deltas, creeks, streams, and estuaries are not rivers. They are channels.
