A diagram of a possible river with the Strahler number of each tributary labeled. In hydrology , a stream order is a positive integer used to describe the level of river branching in a drainage basin. [ 18 ]
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 diagram also shows how human water use impacts where water is stored and how it moves. [ 1 ] The water cycle (or hydrologic cycle or hydrological cycle ) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth .
This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.

The dimensionless Shields Diagram, in combination with the Shields formula is now unanimously accepted for initiation of sediment motion in rivers. Much work was done on river sediment transport formulae in the second half of the 20th century and that work should be used preferably to Hjulström's curve. [3]

[clarification needed] Water enters the mainstem from the river's drainage basin, the land area through which the mainstem and its tributaries flow. [3] A drainage basin may also be referred to as a watershed or catchment. [3] Strahler diagram. Only a segment of the mainstem gets the highest number.
