Bayou Corne in Louisiana, October 2010. In usage in the Southern United States, a bayou (/ ˈ b aɪ. uː, ˈ b aɪ. oʊ /) [1] is a body of water typically found in a flat, low-lying area. It may refer to an extremely slow-moving stream, river (often with a poorly defined shoreline), marshy lake, wetland, or creek.
Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).

The stream order or waterbody order is a positive whole number used in geomorphology and hydrology to indicate the level of branching in a river system.. There are various approaches [1] to the topological ordering of rivers or sections of rivers based on their distance from the source ("top down" [2]) or from the confluence (the point where two rivers merge) or river mouth ("bottom up" [3 ...
Stream gradient may change along the stream course. An average gradient can be defined, known as the relief ratio, which gives the average drop in elevation per unit length of river. [4] The calculation is the difference in elevation between the river's source and the river terminus (confluence or mouth) divided by the total length of the river ...
The continuous differences of properties within the river are dependent primarily on the specific composition of the organisms in different sections of the water. [6] Throughout the continuum of the river, the proportion of the four major food types; shredders, collectors, grazers (scrapers) and predators change. With the exception of the ...
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 ...
The flow of a river can act as a means of transportation for plant and animal species, as well as a barrier. For example, the Amazon River is so wide in parts that the variety of species on either side of its basin are distinct. [19] Some fish may swim upstream to spawn as part of a seasonal migration.
