Kodori river plume. A river plume is a freshened water mass that is formed in the sea as a result of mixing of river discharge and saline seawater. [1] River plumes are formed in coastal sea areas at many regions in the World. River plumes generally occupy wide-but-shallow sea surface layers bounded by sharp density gradients.
Plume shapes can be influenced by flow in the ambient fluid (for example, if local wind blowing in the same direction as the plume results in a co-flowing jet). This usually causes a plume which has initially been 'buoyancy-dominated' to become 'momentum-dominated' (this transition is usually predicted by a dimensionless number called the ...
A river plume embedded into a ROFI reproduce a continuous process of transformation of freshwater discharge. Initially, river discharge enters the shelf sea from a river mouth and forms a sub-mesoscale (with spatial extents ~1-10 km) or mesoscale (with spatial extents ~10-100 km) water mass referred to as a river plume.
[11] [10] [12] At the boundary between this freshwater plume and the surrounding seawater, strong gradients in salinity and density will form. [13] An example of such a front is located in the Chesapeake Bay estuary, but these fronts are also common in front of river outlets such as the Mississippi, Amazon, or Connecticut River. [14]
Tidal salt marsh at Ella Nore in Chichester, England. A tidal marsh (also known as a type of "tidal wetland") is a marsh found along rivers, coasts and estuaries which floods and drains by the tidal movement of the adjacent estuary, sea or ocean. [1]
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 plume is initially laminar, but transition to turbulence occurs in the upper third of the image. The image was made by Gary Settles using a one-meter-diameter schlieren mirror. The general form for the Reynolds number flowing through a tube of radius r (or diameter d ):
Rivers with an average discharge of 5,000 m 3 /s or greater, as a fraction of the estimated global total.. This article lists rivers by their average discharge measured in descending order of their water flow rate.
