The primary factor affecting river regimes is the climate of its catchment area, both by the amount of rainfall and by the temperature fluctuations throughout the year. This has led Beckinsale to classify regimes based primarily on the climate. [23] Although there is correlation, climate is still not fully reflected in a river regime.
The river regime generally refers to the mathematical relationship between the river discharge and its width, depth and slope. Thus, "river regime" describes a series of characteristic power-law relationships between discharge and width, depth and slope [ 1 ]
The "flow regime" of a river or stream includes the general patterns of discharge over annual or decadal time scales, and may capture seasonal changes in flow. [7] [8] While water flow is strongly determined by slope, flowing waters can alter the general shape or direction of the stream bed, a characteristic also known as geomorphology. The ...
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 ...
In the Indian context river flows required for cultural and spiritual needs assumes significance. [1] Through implementation of environmental flows, water managers strive to achieve a flow regime, or pattern, that provides for human uses and maintains the essential processes required to support healthy river ecosystems.
Christopher R. Fielding observed a link between their formation and the climate. Climates that have extreme rainy seasons resulting in runoff create a higher flow velocity within their streams and rivers, thus increasing the ability of upper flow regime structures to form. [2] Here is a video showing the formation and destruction of a modern ...
The headwaters of a river are the smaller streams that feed a river, and make up the river's source. [4] These streams may be small and flow rapidly down the sides of mountains . [ 5 ] All of the land uphill of a river that feeds it with water in this way is in that river's drainage basin or watershed. [ 4 ]
It is important that while there are other contributing factors to such features in the landscape, rejuvenation is one of the major influences. As mentioned, when a river rejuvenates, it gains more energy and erodes vertically to meet its new base level. A river terrace is the remains of an old floodplain at a higher elevation than the present ...
