These streams flow through soft and deep stream beds, carrying mud (lime and clay), sand and, sometimes, gravel. Ultimately, the river flow starts to swing from side to side. Median response time is 34 minutes and may be longer for new subjects. The cross-overs are marked by riffles, or shallow beds, while at the apices are pools. [25], The meanders of a stream or river that has cut its bed down into the bedrock are known as either incised, intrenched, entrenched, inclosed or ingrown meanders. [1][2], The degree of meandering of the channel of a river, stream, or other watercourse is measured by its sinuosity. View original. Leopold, L.B., Wolman, M.G., Wolman, M.G. This stage of meander formation eventually causes the neck of the meander to be breached by the river creating an ox-bow lake. When she is not writing, she loves watching sci-fi movies on Netflix. Fact 2: Typical of meanders are Oxbow lakes. Tiarah May 13, 6:27 PM. Various mathematical formulae relate the variables of the meander geometry. They are typical of the middle and lower course of a river. Because erosion is greatest where the stream flow is ⦠0. The features included under these categories are not random and guide streams into non-random paths. Meander geometry or median planform geometry is engaged in the technical description of meanders. The sinuosity of a watercourse is the ratio of the length of the channel to the straight line down-valley distance. Scheffers, A.M., May, S.M. A river rarely flows in a straight line- it will bend around something in its course for example a tree or hard rock. A lake that occupies a cutoff meander is known as an oxbow lake. Weiss, Samantha Freeman. The flowing water weaves around these bars of sediment which in turn creates deeper pathways where most of the water flows called pools and shallow areas where less water flows called riffles. meander - a bend or curve, as in a stream or river oxbow - a U-shaped curve in a stream stream , watercourse - a natural body of running water flowing on ⦠Meander gradients ⦠What a meander in geography? Fact 10: Typically, meanders belong to a series of regular sinous curves, bends, turns, windings or loops in the channel of a stream, river or other watercourse and the zone within which a meandering stream moves its channel across either its valley floor or floodplain from time to time is known as the ‘meander belt.’. [1] Such lakes form regularly in undisturbed floodplains as a result of the normal process of fluvial meandering. The waveform depends ultimately on the characteristics of the flow but the parameters are independent of it and apparently are caused by geologic factors. What is a Meander? Other articles where Gooseneck is discussed: meander: â¦to constrict and form a gooseneck, an extremely bowed meander. Answers (2) Maylie May 13, 8:08 PM. This type of slip-off slope is often covered by a thin, discontinuous layer of alluvium. After a long period of time, the meander becomes very curved, and eventually the neck of the meander will touch the opposite side and the river will cut through the neck, ⦠A loop at the apex has an outer or concave bank and an inner or convex bank. In the context of meandering rivers, its effects are dominated by those of secondary flow. Nov 13,2020 - What is mean meander in geography in our changing earth? The higher velocities at the outside bend lead to higher shear stresses and therefore result in erosion. In the equilibrium theory, meanders decrease the stream gradient until an equilibrium between the erodibility of the terrain and the transport capacity of the stream is reached. As a result of this stage, undercutting often occurs on the outer bank and deposition on the inner bank of the meander. Therefore, meanders are formed as a river goes around a bend in which most of the flowing water is pushed towards the outside portion of the water flow. In that case the valley index is the meander ratio of the valley while the channel index is the meander ratio of the channel. Thus the curvature of the pathway of river water flow increases, and the shape of the meander changes over time. He argues that the symmetrical valley sides are the direct result of rapid down-cutting of a watercourse into bedrock. Meanders form a snake-like pattern as the river flows across a fairly flat valley floor. The result of all the physical factors acting at random is channels that are not straight, which then progressively become sinuous. (oceanography) A deviation of the flow pattern of a current. The course at that point is the apex. As it turns out some numerical parameters can be established, which appear in the formulae. A corkscrew-like flow of water called Helicoidal Flow moves material from the outside of one meander bend and deposits it on the inside of the next bend. The middle course of a river has more energy and volume then in the upper course. Usually, the energy accompanying flow water in a river decreases progressively from the upper course of the river to the lowest course of the river. At any cross-section the flow is following the sinuous axis, the centerline of the bed. This is due to the fact that the water on the outside bend of river water flow is deeper and runs faster than the water flowing at the inside portion of the bend. At the end of this process, the original meander is separated from the river, and its water stops flowing. The greater the curvature of the bend, and the faster the flow, the stronger is the cross-current and the sweeping. This is because the tops can be shaped by wind, either adding fine grains or by keeping the area unvegetated, while the darkness in the swales can be attributed to silts and clays washing in during high water periods. (April 2016). A meander is a bend or a loop in in a riverchannel. Meander gradients are usually more gentle and they experience lateral (sideways) erosions which widen the channel of the river at the middle and lower courses of a river. entrenched meanders are symmetrical and form when the river downcuts particularly quickly. (And Which Foods Do They Actually Like), How Do Birds Mate? This is because vertical erosion is replaced by a sideways form of erosion called LATERAL erosion, plus deposition within the floodplain. Earth Eclipse. Streams can be placed in categories arranged by it; for example, when the index is between 1 and 1.5 the river is sinuous, but if between 1.5 and 4, then meandering. A meander is produced by a stream or river as it erodes the sediments comprising an outer, concave bank (cut bank) and deposits this and othe⦠The curvature varies from a maximum at the apex to zero at a crossing point (straight line), also called an inflection, because the curvature changes direction in that vicinity. Meanders are typical landforms at the middle and lower courses of a river. So if your students were investigating a meander this year, they would need to be very careful to avoid ANY reference to erosion ⦠The steeper drop in gradient causes the river flow gradually to abandon the meander which will silt up with ⦠Be the first to answer! The river length is the length along the centerline. Eventually as the result of its meandering, the fluvial channel cuts through the narrow neck of the meander and forms a cutoff meander. Thus, during low flow conditions, straight river channels develop bars of sediment on their beds which leads to an eventual formation of deeper pathways which ultimately allow more flow of water and consequent formation of a sinusoidal flow of water. Natural surfaces are rough and erodible to different degrees. Distinctions may become even more subtle.[45]. Meander definition is - a winding path or course; especially : labyrinth. The flow is supplied by a counter-flow across the surface from the inside to the outside. [1][3], The term derives from the Meander River located in present-day Turkey and known to the Ancient Greeks as ÎαίανδÏÎ¿Ï Maiandros (Latin: Maeander),[4] characterised by a very convoluted path along the lower reach. Meanders are typical landforms at the middle and lower courses of a river. What is Lagoon? A resultant increase in flow energy is also exhibited. Morphotectonic means having to do with the deeper, or tectonic (plate) structure of the rock. Meanders are sinuously curves in which water streams move among, transporting high quantities of sediments in suspension (1). As to why streams of any size become sinuous in the first place, there are a number of theories, not necessarily mutually exclusive. Inside that layer and following standard boundary-layer theory, the velocity of the fluid is effectively zero. Fact 5: Meanders are popularly described by the Stochastic theory. Eventually two outside bends get closer together as processes continue creating a small area of land separating the neck of the meander.

The term âmeanderâ is one which refers to a winding curve or bend in a River. [12] The cross-current then rises to the surface near the inside and flows towards the outside, forming the helical flow. Some associated landforms include: Cut banks, Meander cutoffs, Incised meanders, Oxbow lakes, Scroll bars, and Slip-off slope. Thalweg: (this is not a landform but has to do with erosion and deposition) This is the line of fastest flow in a stream and is usually exaggerated variation of the stream channel shape that crosses to the outside of each meander at the point of inflection. define a meander loop. The line of maximum depth, or channel, is the thalweg or thalweg line. It is produced by a stream or river swinging from side to side as it flows across its floodplain or shifts its channel within a valley. For example, the stream might be guided into a fault line (morphotectonic). [38] This term can also be applied to the inside, sloping bank of a meandering tidal channel. [13], Due to the conservation of angular momentum the speed on the inside of the bend is faster than on the outside. A stream of any volume may assume a meandering ⦠The channel sinuosity index is the channel length divided by the valley length and the standard sinuosity index is the channel index divided by the valley index. [20][21], As the cut bank is undermined by erosion, it commonly collapses as slumps into the river channel. The zone within which a meandering stream shifts its channel across either its floodplain or valley floor from time to time is known as a meander belt. Meandering River Dynamics (Doctoral dissertation). Retrieved from: Meander floodplains. In contrast to sine waves, the loops of a meandering stream are more nearly circular. From here, two opposing processes occur: (1) irrotational flow and (2) secondary flow. They are predictable obstacles that instigate meander formation by deflecting the stream. This type of slip-off slope is located opposite the cutbank. This initiates helicoidal flow: Along the river bed, fluid roughly follows the curve of the channel but is also forced toward the inside bend; away from the river bed, fluid also roughly follows the curve of the channel but is forced, to some extent, from the inside to the outside bend. The orientation angle is the angle between sinuous axis and down-valley axis at any point on the sinuous axis. In the words of Elizabeth A. Sinuosity Index has a non-mathematical utility as well. [1] As in the case of the Anderson Bottom Rincon, incised meanders that have either steep-sided, often vertical walls, are often, but not always, known as rincons in the southwest United States. The sediment eroded from a cut bank tends to be deposited on the point bar of the next downstream meander, and not on the point bar opposite it. The shortest distance; that is, a straight channel, results in the highest energy per unit of length, disrupting the banks more, creating more sediment and aggrading the stream. A perfectly straight river would have a meander ratio of 1 (it would be the same length as its valley), while the higher this ratio is above 1, the more the river meanders. A meander is a curve in a river. The meanders in the jet stream flow slower than the rest of the air and are called Rossby Waves. The pressure of the super-elevated column prevails, developing an unbalanced gradient that moves water back across the bottom from the outside to the inside. Irrotational flow: From Bernoulli's equations, high pressure results in low velocity. As a result, the meander erodes and migrates in the direction of the outside bend, forming the cut bank. This theory states that: The meander train is assumed to be a result of the stochastic fluctuation of the direction of flow due to the random presence of direction-changing obstacles in the path of a river. The meander arc length is the distance along the thalweg over one meander. Typically, the sediment consists of either sand, gravel, or a combination of both. They move slower because they are caused by the Coriolis Effect and turn west in respect to the flow of air they are embedded in. This axis represents the overall direction of the stream. [27][29], As noted above, it was initially either argued or presumed that an incised meander is characteristic of an antecedent stream or river that had incised its channel into underlying strata. Tags: river meander flow. In a pool direction of flow is downward, scouring the bed material. Start studying Meanders- Geography. A meander has a depth pattern as well. More water is gained by the deepening bend as the river makes its way to the middle course of the river. Search for: Support. Comment; Complaint; Link; Braiden May 13, 8:07 PM. Learn more. [26][27] However, later geologists[30] argue that the shape of an incised meander is not always, if ever, "inherited," e.g., strictly from an antecedent meandering stream where it meander pattern could freely develop on a level floodplain. This causes the meander to shift so that the bend in the river becomes more and more exaggerated. Silt deposits will eventually fill the lake to form a marsh or meander scar. and Kelletat, D.H., 2015. [1][20][21], Scroll-bars are a result of continuous lateral migration of a meander loop that creates an asymmetrical ridge and swale topography[33] on the inside of the bends. As the loop is not ideal, additional information is needed to characterize it. As a result, even in Classical Greece (and in later Greek thought) the name of the river had become a common noun meaning anything convoluted and winding, such as decorative patterns or speech and ideas, as well as the geomorphological feature. Geography. Q: What is the explanation for the thinning of the ozone layer that has been observed since the 1970s? How to use meander in a sentence. [14], Since the flow velocity is diminished, so is the centrifugal pressure. They result from erosional and depositional processes at this level of rivers mainly due to the high energy and flow of water. When a fluid is introduced to an initially straight channel which then bends, the sidewalls induce a pressure gradient that causes the fluid to alter course and follow the bend. The index is a measure also of stream velocity and sediment load, those quantities being maximized at an index of 1 (straight). [22][23], 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. But a meander is landform of erosion. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. [5] Strabo said: ââ¦its course is so exceedingly winding that everything winding is called meandering.â[6]. It is produced by a stream or river swinging from side to side as it flows across its floodplain or shifts its channel within a valley. A meander is one of a series of regular sinuous curves, bends, loops, turns, or windings in the channel of a river, stream, or other watercourse. [9] It is characterized as an irregular waveform. New GCSE geography retrieval revision 2 November 2020 - 4:17 pm One subject to unite all 3 October 2020 - 7:05 pm Extinction The Facts 14 September 2020 - ⦠The meander is then said to be freeâit can be found anywhere in the flood plain. The term ‘meander’ is one which refers to a winding curve or bend in a river. The meander is two consecutive loops pointing in opposite transverse directions. Meanders are the result of both erosional and depositional processes. Meanders are usually exhibited at the middle course of rivers. The gradient is more gentle and lateral (sideways) erosion has widened the channel. The final break-through of the neck, which is called a neck cutoff, often occurs during a major flood because that is when the watercourse is out of its banks and can flow directly across the neck and erode it with the full force of the flood. The oxbow lakes are also known as ‘cut-off lakes’. However they are also found in the old stage where they become very pronouced and are also accompanied by oxbow lakes. A meander is produced by a stream or river as it erodes the sediments comprising an outer, concave bank (cut bank) and deposits this and other sediment downstream on an inner, convex bank which is typically a point bar. The technical definitions of this section rely heavily on. [19] A mass of water descending must give up potential energy, which, given the same velocity at the end of the drop as at the beginning, is removed by interaction with the material of the stream bed. These processes can be categorized into the following stages: During low flow conditions, straight river channels have bars of sediment on their beds. dÉr] (hydrology) A sharp, sinuous loop or curve in a stream, usually part of a series. [1] Erosion that forms a cut bank occurs at the outside bank of a meander because helicoidal flow of water keeps the bank washed clean of loose sand, silt, and sediment and subjects it to constant erosion. Therefore, in the absence of secondary flow we would expect low fluid velocity at the outside bend and high fluid velocity at the inside bend. [22][32], After a cutoff meander is formed, river water flows into its end from the river builds small delta-like feature into either end of it during floods. Learn vocabulary, terms, and more with flashcards, games, and other study tools. [31] Oxbow lakes are also known as cutoff lakes. A meander is a winding curve or bend in a river. The presence of meanders allows the stream to adjust the length to an equilibrium energy per unit length in which the stream carries away all the sediment that it produces. Statistical Self-Similarity and Fractional Dimension, https://en.wikipedia.org/w/index.php?title=Meander&oldid=991235661, Short description is different from Wikidata, Srpskohrvatski / ÑÑпÑÐºÐ¾Ñ ÑваÑÑки, Creative Commons Attribution-ShareAlike License, This page was last edited on 29 November 2020, at 00:46. a small water body with surface water flowing within the bed and banks of the channel When looking down the river valley they can be distinguished because the point-bar scroll patterns are convex and the eddy accretion scroll bar patterns are concave.[37]. © 2020 . If there is no flood plain, the meanders are fixed. How do Rainbows Form? The maximum distance from the down-valley axis to the sinuous axis of a loop is the meander width or amplitude. Her passion for science education drove her to start EarthEclipse with the sole objective of finding and sharing fun and interesting science facts. The point bar or meander bar is a gently sloping deposit of sand, gravel, and pebbles. Fact 3: The term ‘incised meander’ refers to meanders of a stream or river which has cut its bed down into the bedrock. By: rgamesby. Just after the cutoff meander is formed, the river flows into its end from the river and builds a small delta which eventually results in the formation of oxbow lakes. Share. Fluid flows around a bend in a vortex. Middle course of a River. In the context of meandering rivers, a boundary layer exists within the thin layer of fluid that interacts with the river bed. The formation of a meander. Furthermore, if this is broken through, often in flood the river follows shortest ⦠Meander gradients are usually more gentle and they experience lateral (sideways) erosions which widen the channel of the river at the middle and lower courses of a ⦠The Meander River is south of Izmir, east of the ancient Greek town of Miletus, now Milet, Turkey. Depending upon whether a meander is part of an entrenched river or part of a freely meandering river within a floodplain, the term slip-off slope can refer to two different fluvial landforms that comprise the inner, convex, bank of a meander loop. Fact 9: Erosion, therefore, occurs on the outside of meander bends while deposition occurs on the inner side of meander bends (which might eventually lead to the formation of oxbow lakes).
