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 ...
The specific objectives of this stream classification system are as follows: 1) predict a rivers behavior from its appearance; 2) develop specific hydrologic and sediment relationships for a given stream type and its state; 3) provide mechanisms to extrapolate site-specific data to stream reaches having similar characteristics; and 4) provide a ...
Often confused with braided channels, anastomosing is reserved for a type of river with multiple, interconnected, coexisting channel belts on alluvial plains. Based on its geomorphology, saucer-shaped islands called flood-basins characterize anastomosing rivers. [ 5 ]
Dendritic drainage: the Yarlung Tsangpo River, Tibet, seen from space: snow cover has melted in the valley system. In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is ...

Point bar at a river meander: the Cirque de la Madeleine in the Gorges de l'Ardèche, France. Any fluid, including water in a stream, can only flow around a bend in vortex flow. [ 1 ] In vortex flow the speed of the fluid is fastest where the radius of the flow is smallest, and slowest where the radius is greatest.
the location where a river flows into an ocean, sea, estuary, lake, or reservoir. Distributary or distributary channel: a stream that branches off and flows away from the main stream channel. Drainage basin: a region of land where water from rain or snowmelt drains downhill into another body of water, such as a river, lake, or reservoir. Draw
The faster the water in a river channel, the better it is able to pick up greater amounts of sediment, and larger pieces of sediment, which increases the river's bed load. [4] Over a long enough period of time, the combination of deposition along point bars, and erosion along cut banks can lead to the formation of an oxbow lake .
