Rocky stream in Italy Frozen stream in Enäjärvi, Pori, Finland Stream near Montriond in south-eastern France Aubach (Wiehl) in North Rhine-Westphalia, Germany. A stream is a continuous body of surface water [1] flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a ...
A stream can be used similarly to a list, but later elements are only calculated when needed. Streams can therefore represent infinite sequences and series. [1] In the Smalltalk standard library and in other programming languages as well, a stream is an external iterator. As in Scheme, streams can represent finite or infinite sequences.
The joints are usually less resistant to erosion than the bulk rock so erosion tends to preferentially open the joints and streams eventually develop along the joints. The result is a stream system in which streams consist mainly of straight line segments with right-angle bends and tributaries join larger streams at right angles. [2]
In hydrology, a stream order is a positive integer used to describe the level of river branching in a drainage basin. [18] Several systems of stream order exist, one of which is the Strahler number. In this system, the first tributaries of a river are 1st order rivers. When two 1st order rivers merge, the resulting river is 2nd order.
The River Continuum Concept is based on the idea that a watercourse is an open ecosystem that is in constant interaction with the bank, and moving from source to mouth, constantly changing. [4] Basis for this change in the overall system is due to the gradual change of physical environmental conditions such as the width, depth, water, flow ...
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.
Conversely, explorers approaching a new land from the sea encounter its rivers at their mouths, where they name them on their charts, then, following a river upstream, encounter each tributary as a forking of the stream to the right and to the left, which then appear on their charts as such; or the streams are seen to diverge by the cardinal ...
Streamflow, or channel runoff, is the flow of water in streams and other channels, and is a major element of the water cycle.It is one runoff component, the movement of water from the land to waterbodies, the other component being surface runoff.
