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.
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.
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 ...
Hydrothermal vent fluids harbor temperatures (~40 to >400 °C) well above that of ocean floor seawater (~4 °C), meaning that hydrothermal fluid is less dense than the surrounding seawater and will rise through the water column due to buoyancy, forming a hydrothermal plume; therefore, the phase during which hydrothermal plumes rise through the ...
An atmospheric river (AR) is a narrow corridor or filament of concentrated moisture in the atmosphere. Other names for this phenomenon are tropical plume, tropical connection, moisture plume, water vapor surge, and cloud band.

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 ):
For example, the origin of the Nile River is the confluence of the White Nile and the Blue Nile, but the source of the whole river system is in its upper reaches. If there is no specific designation, "length of the Nile" refers to the "river length of the Nile system", rather than to the length of the Nile river from the point where it is ...
Meaning that previous research was always only on small pieces of water and only rarely was the entire river system considered, allowing for the creation of a general model. After its publication, the River Continuum Concept was adopted as the accepted model in the limnology community, becoming a favorite means for describing the communities ...
