Vivari Channel in Albania links Lake Butrint with the Straits of Corfu. In physical geography and hydrology, a channel is a landform on which a relatively narrow body of water is situated, such as a river, river delta or strait. While channel typically refers to a natural formation, the cognate term canal denotes a similar artificial structure.
where is the volumetric discharge, ¯ is the mean flow velocity, is the channel width (breadth) and is the channel depth. Because of this relationship, as discharge increases, depth, width, and/or mean velocity must increase as well.
A thalweg is the center of the principal navigable channel of the waterway (which is presumed to be the deepest part). [8] If there are multiple navigable channels in a river, the one principally used for downstream travel (likely having the strongest current) is used. [8] The definition has been used in specific descriptions as well.
where is the channel length, is the channel width (breadth), and is the channel depth (height). We use the definition of discharge = where is the cross-sectional area, which can often be reasonably approximated as a rectangle with the characteristic width and depth. This absorbs velocity, width, and depth.
The fairway depth of a river varies with the season, so some standardized depth value is used, usually the one corresponding to the low navigable water level (LNWL) defined as the water level that the river stays above during almost the entire navigation season: statistically, the level shall stay below the LNWL for 20 ice-free days per year ...
The English Channel, [a] [1] also known as the Channel, is an arm of the Atlantic Ocean that separates Southern England from northern France. It links to the southern part of the North Sea by the Strait of Dover at its northeastern end. It is the busiest shipping area in the world. [2]
The Bradshaw Model is an idealised geographical model which suggests how a river's characteristics vary between the upper course and lower course of a river. It indicates how discharge, occupied channel width, channel depth, and average load quantity increase downstream, [1] and other properties such as load particle size, channel bed roughness, and gradient as characteristics that decrease.
The SOFAR channel (short for sound fixing and ranging channel), or deep sound channel (DSC), [1] is a horizontal layer of water in the ocean at which depth the speed of sound is at its minimum. The SOFAR channel acts as a waveguide for sound, and low frequency sound waves within the channel may travel thousands of miles before dissipating.
