When a meander gets cut off from the main stream, an oxbow lake is formed. The result is a snaking pattern as the stream meanders back and forth across its down-valley axis. A stream of any volume may assume a meandering course, alternately eroding sediments from the outside of a bend and depositing them on the inside. A meander is formed when the moving water in a stream erodes the outer banks and widens its valley and the inner part of the river has less energy and deposits what it is carrying. Streams or rivers with a single channel and sinuosities of 1.5 or more are defined as meandering streams or rivers.įreebase Rate this definition: 0.0 / 0 votesĪ meander, in general, is a bend in a sinuous watercourse or river. 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. The painter Yang Liu, for example, has incorporated smooth versions of the traditional Greek Key (also called Sona drawing, Sand drawing, and Kolam) in many of her paintings.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. Meanders and their generalizations are used with increasing frequency in various domains of contemporary art. A meander motif also appears in prehistoric Mayan design motifs in the western hemisphere, centuries before any European contacts. 202 BC) by way of trade with the Greco-Bactrian Kingdom. 1000 BC -600 BC), frequently there is speculation that meanders of Greek origin may have come to China during the time of the Han Dynasty (c. Although space-filling curves have a long history in China in motifs more than 2,000 years earlier, extending back to Zhukaigou Culture (c. 1045 BC), and many traditional buildings in and around China still bear geometric designs almost identical to meanders. The meander is a fundamental design motif in regions far from a Hellenic orbit: labyrinthine meanders ("thunder" pattern ) appear in bands and as infill on Shang bronzes (c. The design is common to the present-day in classicizing architecture, and is adopted frequently as a decorative motif for borders for many modern printed materials. In ancient Greece they appear in many architectural friezes, and in bands on the pottery of ancient Greece from the Geometric Period onward. On another hand, as Karl Kerenyi pointed out, "the meander is the figure of a labyrinth in linear form".Meanders are common decorative elements in Greek and Roman art. On one hand, the name "meander" recalls the twisting and turning path of the Maeander River in Asia Minor (present day Turkey) that is typical of river pathways. Usually the term is used for motifs with straight lines and right angles and the many versions with rounded shapes are called running scrolls or, following the etymological origin of the term, may be identified as water wave motifs. Such a design also may be called the Greek fret or Greek key design, although these terms are modern designations even though the decorative motif appears thousands of years before that culture, thousands of miles away from Greece, and among cultures that are continents away from it. Among some Italians, these patterns are known as "Greek Lines".
