The Rakaia River in the South Island of New Zealand is braided over most of its course. A braided river (also called braided channel or braided stream) consists of a network of river channels separated by small, often temporary, islands called braid bars or, in British English usage, aits or eyots.
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.
The term anabranching river describes a river with many anabranches, whilst an anastomosing river is an organic-rich subset of this river type. [1] The term braided river describes watercourses which are divided by small islands into multiple channel threads within a single main channel, but the term does not describe the multiple channels of ...
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 Platte River (/ p l æ t /) is a major American river, in the state of Nebraska. It is about 310 mi (500 km) long; measured to its farthest source via its tributary, the North Platte River , it flows for over 1,050 miles (1,690 km).
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.
Bar Initiation: The braid bar will form following a series of dune amalgamations. As sediments are deposited to form the braid bar, flow in the channel begins to diverge, with the braid bar acting as a wedge. This stage is associated with high flow in the braided river. Bar Growth: Dune amalgamation continues as an accretionary dune front is ...
