WebNov 26, 2009 · In fact the ratio is approximately 3.14, which is close to the value of the number pi… The ratio of pi is most commonly found for rivers flowing across very gently sloping planes, such as those found in Brazil or the Siberian tundra.” Makes sense since each meander is, on average, the arc of a semicircle. WebJan 1, 2014 · This is the ratio between radius of the meander curvature (r) and the wavelength (λ) of the meander. The ratio for a perfect sine generated curve of single line …
WebJun 19, 2024 · A symmetry index was calculated for each meander as defined by the ratio of the eroded areas created in the upstream versus downstream portions of the meander (see the methods in the Data Repository). Large σ values are indicative of downstream rotation, while small values describe more extensional or upstream bend deformation.

WebSep 27, 2006 · The hyporheic fluxes induced at the meander scale by the river sinuosity can therefore be computed. The application of the model to a simulated case has shown the fundamental role of the river planimetry on the hyporheic exchange pattern at the meander scale, and its influence on the long-term evolution of the hyporheic exchange.
The meander ratio or sinuosity index is a means of quantifying how much a river or stream meanders (how much its course deviates from the shortest possible path). It is calculated as the length of the stream divided by the length of the valley. A perfectly straight river would have a meander ratio of 1 (it would … See more A meander is one of a series of regular sinuous curves in the channel of a river or other watercourse. It is produced as a watercourse erodes the sediments of an outer, concave bank (cut bank or river cliff) and deposits … See more Meanders are a result of the interaction of water flowing through a curved channel with the underlying river bed. This produces helicoidal flow, in which water moves from the outer to the inner bank along the river bed, then flows back to the outer bank near the … See more Once a channel begins to follow a sinusoidal path, the amplitude and concavity of the loops increase dramatically. This is due to the effect of helical flow which … See more • Baer's law • Billabong • Crevasse splay • Helicoidal flow • Jet stream • Meander cutoffs in Avulsion (river) See more The term derives from the winding river Menderes located in Asia-Minor and known to the Ancient Greeks as Μαίανδρος Maiandros ( See more The technical description of a meandering watercourse is termed meander geometry or meander planform geometry.
