The enormous Brahmaputra river in Northeastern India is a classic example of a braided river. [18] A notable example of a large braided stream in the contiguous United States is the Platte River in central and western Nebraska. [19] Platte-type braided rivers are characterized by abundant linguoid (tonguelike) bar and dune deposits. [20]
Braided rivers, which form in (tectonically active) areas that have a larger sedimentary load than the discharge of the river and a high gradient. Meandering rivers , which form a sinuous path in a usually low-gradient plain toward the end of a fluvial system.
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.
Braided river channels are broad and shallow and found in areas where sediment is easily eroded like at a glacial outwash, or at a mountain front with high sediment loads. [1] [2] These types of river systems are associated with high slope, sediment supply, stream power, shear stress, and bed load transport rates. [2] Braided rivers have ...
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 ...
Braided rivers have a channel that consists of a network of small channels separated by small and often temporary islands called braid bars. Also called braided streams, anastomose streams or anastomose rivers.
An example of a river running through a sand bar is the Columbia Bar—the mouth of the Columbia River. A stream channel is the physical confine of a stream consisting of a bed and stream banks. Stream channels exist in a variety of geometries. Stream channel development is controlled by both water and sediment movement.
The generally coarse material is the result of the processes common to braid bar formation, and more broadly, braided rivers. Braided rivers are defined by relatively high flow power, as well as significant rates of erosion. [3] These high rates of flow will transport fine-grained materials further downstream, while coarser material remains ...
