Types of River Channels
The Humptulips River (left) is a typical alluvial river, while Rush Creek (right) is an example of a non-alluvial river. Both are in Washington State. The second type of river, the "alluvial," is encountered in places less steep, in the bottom of wider valleys, valleys that have flat bottomland (the floodplain) bordering the river.
River channel types: straight, meandering, braided, anastomosing
The river channel contains sediment bars, giving it a braided appearance. For a braided channel to form, there must be plenty of sediments available in the channel to build up bars. Bars can be made of a variety of sediments: silts and sands, gravels, or larger stones. The locations and shapes of sediment bars change over time. Although the ...
18.2: Channel Geometry and Flow Characteristics
Channel geometry and characteristics of stream flow are inherently related. Changes in the geometry of the channel can impact stream velocity and discharge. Figure 18.2.1 18.2. 1: Cross-sectional area. The cross-sectional area of the stream is determined by multiplying channel depth by channel width along a transverse section of the stream.
Channel types
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.
River Channel Types on the Landscape
The stream will curve or meander back and forth, forming a deep pool on the outside of each bend, and a gravel or sand bar on the inside of the bend. The channel between bends in the river becomes shallow and turbulent, and is called a riffle. Upstream, the alluvial stream channel is made of gravel.
5.5: The Morphology of Rivers
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.
Understanding Rivers
The deepest part of a river bed is called a channel. The channel is usually located in the middle of a river. Here, the current is often strong. In large rivers, ships travel in channels. Engineers may dredge, or dig, deeper channels so more water can flow through the river or the river can transport larger ships.
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 shallow reaches, regardless of the type of pattern. The length of the pool or distance between riffles in a straight channel equals the ...

River
river, (ultimately from Latin ripa, "bank"), any natural stream of water that flows in a channel with defined banks . Modern usage includes rivers that are multichanneled, intermittent, or ephemeral in flow and channels that are practically bankless. The concept of channeled surface flow, however, remains central to the definition. The word stream (derived ultimately from the Indo-European ...
River
River - Straight Channels, Erosion, Deposition: Straight channels, mainly unstable, develop along the lines of faults and master joints, on steep slopes where rills closely follow the surface gradient, and in some delta outlets. Flume experiments show that straight channels of uniform cross section rapidly develop pool-and-riffle sequences. Pools are spaced at about five bed widths. Lateral ...
Channel (geography)
Channel (geography) 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 ...
Types of river channel patterns and their natural controls
Abstract. 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).
Rivers and Streams: Life in Flowing Water
The interstitial, water-filled space beneath river beds, where most active aquifer-river water exchange occurs, is termed the hyporheic zone, and is an important habitat for a number of aquatic ...
Fluvial Geomorphology
An understanding of river- and stream-channel geomorphic responses to various human-caused and natural disturbances is important for effective management, conservation, and rehabilitation of rivers and streams to accommodate multiple, often conflicting, needs. Channel changes may have implications for the protection of property and structures, water supply, navigation, and habitat.
Channel pattern
Channel pattern. Channel patterns are found in rivers, streams, and other bodies of water that transport water from one place to another. Systems of branching river channels dissect most of the sub-aerial landscape, each in a valley proportioned to its size. Whether formed by chance or necessity, by headward erosion or downslope convergence ...

Columbia River Cross Channel Swim return on Sept. 2, 2024
Swimmers board the historic Columbia Gorge sternwheeler and are ferried across the channel before anchoring on Washington's shores. Upon a signal, participants leap from the decks into the river waters, commencing a 1.1-mile open water swim toward the Columbia River's south (Oregon) shore.
