What does meander cutoff mean? - Definitions.net
Webhas had its lower course cut off by the lateral migration of a meander of the river. Such a cut-off evidently produced cascades or rapids at the new mouth of the creek and, as far as this study is concerned, has the same effect as a cut-off meander. Finally, the three examples already investigated in Belgium (Nos. 72, 73, and 74) give a total of WebSketch and describe the evolution of a meander, including how a cutoff meander forms and how it can lead to an oxbow lake.

Meander cutoff - Wikipedia
A meander cutoff, also known as either a cutoff meander or abandoned meander, is a meander that has been abandoned by its stream after the formation of a neck cutoff. A lake that occupies a cutoff meander is known as an oxbow lake. Cutoff meanders that have cut downward into the underlying bedrock … 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) and deposits sediments … 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 sweeps dense eroded material towards the inside of the bend, and leaves the … See more 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 … See more The term derives from the winding river Menderes located in Asia-Minor and known to the Ancient Greeks as Μαίανδρος Maiandros (Latin: Maeander), characterised by a … See more The technical description of a meandering watercourse is termed meander geometry or meander planform geometry. It is characterized as an … See more Cut bank A cut bank is an often vertical bank or cliff that forms where the outside, concave bank of a meander cuts into the floodplain or valley wall of a river or stream. A cutbank is also known either as a river-cut cliff, river cliff, or a … See more WebNov 7, 2024 · A meander cutoff, also known as either a cutoff meander or abandoned meander, is a meander that has been abandoned by its stream after the formation of a … Webchute, or Cutoff, in a river, shortcut across a meander ( q.v. ). loop that shortens and straightens the course of the stream. Chutes are formed by lateral erosion of the bank of the upstream arm of a loop, which causes the stream to cut through the neck of the loop into the downstream arm. cord clearing
