The sinuosity of a watercourse is the ratio of the length of the channel to the straight line down-valley distance. Over time, meanders migrate downstream, sometimes in such a short time as to create civil engineering challenges for local municipalities attempting to maintain stable roads and bridges.The degree of meandering of the channel of a river, stream, or other watercourse is measured by its sinuosity. It typically ranges from 15 to 18 times the width of the channel. The result of this coupled erosion and sedimentation is the formation of a sinuous course as the channel migrates back and forth across the axis of a floodplain.The zone within which a meandering stream periodically shifts its channel is known as a meander belt. It is produced as a watercourse erodes the sediments of an outer, concave bank (cut bank) and deposits sediments on an inner, convex bank which is typically a point bar. Instead, the Grand Canyon has a winding course called an entrenched meander from the Latin maendere, “to wander”.Wikipedia Rate this definition: 0.0 / 0 votesĪ meander is one of a series of regular sinuous curves in the channel of a river or other watercourse. Though it did mean that I did a couple of placemats - I made up 8 or so of these from scrap pairs which I've been using as enders and leaders - I thought I'd practice some of the 72 ways not to stipple or meander from the new Dijanne Cevaal book I got - the placemat on left is actually from the other day and has a leaf type meander, the one on the right has a "paisley" design - wavy lines, with straight lines and dots down the middle. The word meander derives via Greek from the name of this river in the antiquity, Maiandros. The river was notable for its wandering course hence our modern term meander and in time it would silt up the entire bay between Priene and Miletus. Near the west coast of Asia Minor, a river named Meander, the river from which the word meander is coined, spills into a dismal swampy plain in the country that today is Turkey. noun a bend or curve, as in a stream or river.noun an aimless amble on a winding course.verb to move or cause to move in a sinuous, spiral, or circular course.verb To wind, turn, or twist to make flexuous to wanderįrom WordNet 3.0 Copyright 2006 by Princeton University.noun mathematics A self-avoiding closed curve which intersects a line a number of times.noun hydrology A winding, crooked, or involved course as, the meanders of an old river.transitive verb To wind, turn, or twist to make flexuous.įrom Wiktionary, Creative Commons Attribution/Share-Alike License. ![]()
