Webmeander belt: [noun] the part of a valley bottom across which a stream shifts its channel from time to time especially in flood. WebMar 18, 2014 · The evolution of the point bars played a significant role in dictating preserved facies distributions, with high flood-stage nucleation and accretion of meander scrolls later reworked during waning flood-stages. At a larger scale, meander belt morphodynamics were also a function of valley confinement and contrasts in substrate erodibility.

WebPrint this page. ALLUVIAL ENVIRONMENTS. The principal subenvironments of the meandering stream plain are the meander belt and the flood basin or backswamp ( Figure 3 ). Once the stream occupies a course within the valley it meanders within a belt determined by the radius of curvature of the meander. This belt is from 18 to 20 times … WebMeander belt."

WebThe meander belt is defined by an average meander width measured from outer bank to outer bank instead of from centerline to centerline. If there is a flood plain, it extends beyond the meander belt. The meander is then said to be free—it can be found anywhere in the flood plain. If there is no flood plain, the meanders are fixed. The meander belt is defined by an average meander width measured from outer bank to outer bank instead of from centerline to centerline. If there is a flood plain, it extends beyond the meander belt.

If there is no flood plain, the … 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 … 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).
