Over time, meanders become larger and more visible.Įventually meanders turn into oxbow lakes when two outside bends erode together making a shorter route for the water. A meander can be defined as a series of turns, loops, bends or windings in the channel of a river or other watercourse (Fig. Most of the river is now a tail water fishery after the building Huntsman Lake above the town of. A meander is a bend in a sinuous watercourse or river. Over recent years, the Meander has changed. The slower water drops sediment.Ĭontinuous erosion on the outer bank and deposition on the inner bank will expand the bend in the river. The word meander originated from the Greek word Maiandros. Cellular modelling of river catchments and reaches: Advantages, limita. Figure 5-36 shows most of the elements of a meandering river system. The river flows more slowly on the inside of the river beach. Complexity, self-organisation and variation in behaviour in meandering. First, some descriptive stuff on the geometry of meandering rivers. The river flows faster on the outside of a curve, and the fast water erodes the outside bends of a river channel by hydraulic action and abrasion. Find high-quality stock photos that you wont find anywhere. There are areas of slower and faster water movement. Search from 84120 Meander River stock photos, pictures and royalty-free images from iStock. Meanders were named for a river in Anatolia.Ī river rarely flows in a straight line: it bends around because it drops sediment where it flows most slowly. ![]() Both empirical studies and theory have helped to define the conditions that control channel pattern (1115). Meandering rivers have curvy channels characterized by erosion and deposition along their inner and outer banks, respectively. The position of the curves changes over time. In settings where rivers are not laterally confined by resistant valley walls either the planform generally displays sinuous meandering of a single channel or the river splits into multiply interconnected braided channels. Meanders are produced when water in the stream channel erodes the sediments of an outer bend of a streambank and deposits this and other sediment on. Remember, streams are transport machines, moving water and sediment from their watersheds relentlessly downslope. Meanders form a snake-like pattern as the river flows across a fairly flat valley floor. Streams meander to maintain equilibrium a dynamically stable form and function. Meanders of the Rio Cauto, Cuba Uvac canyon, an incised meander in Serbia Life history of a meanderĪ meander is a curve in a river.
