Therefore, in addition to growing laterally, the bends also gradually migrate down the valley. Due to the slope of the channel, erosion is more effective on the downstream side of a meander. Thus by eroding its outer bank and depositing material along its inner bank, a stream moves sideways without changing its channel size. At the same time the reduced current at the inside of the meander results in the deposition of coarse sediment, especially sand. The sideways movement occurs because the maximum velocity of the stream shifts toward the outside of the bend, causing erosion of the outer bank. click for more detailed meaning in English, definition, pronunciation and example sentences for. (Verb): To move or cause to move in a sinuous, spiral, or circular course 2. Meanders change position by eroding sideways and slightly downstream. meander meaning and definition: Verb: meander meea. Where the bends of two meanders meet, they bypass the curve of river, creating an oxbow lake which may then be infilled with overwash sediment. This creates an erosional surface on the outer edge (a cut bank) and a depostional surface on the inner edge (a point bar). To meander means to follow a winding or flexuous course: and when it is said. Phil Reiker, NPS Geologic Resources DivisionĪ meandering stream has a single channel that winds snakelike through its valley, so that the distance 'as the stream flows' is greater than 'as the crow flies.' As water flows around these curves, the outer edge of water is moving faster than the inner. Find the legal definition of MEANDER from Blacks Law Dictionary, 2nd Edition. Meanders, named from the Menderes (historically known as the Maeander) River in Turkey, are most often formed in alluvial materials (stream-deposited sediments) and thus freely adjust their shapes and shift downstream according to the slope of the alluvial valley. Similar words of Meander are also commonly used in daily talk like as Meanderingly, Meandered. meander, extreme U-bend in the course of a stream, usually occurring in a series. bends in a river, formed when the faster moving water erodes the outer sides of the river from side to side widening into the valley and deposition occurs on the opposing side of the river where velocity is low, making S shaped curves. Oxbow lake formation in a meandering stream Meander synonym words are included Thread, Wander, Weave, Wind.
