#MEANDER RIVER ALASKA FULL#

The term derives from a river located in present-day Turkey and known to the Greeks as ( Μαίανδρος) Maiandros or Maeander, characterised by a very convoluted path along the lower reach.

3.3 Geomorphic and morphotectonic theory.

All streams are sinuous at some time in their geologic history over some part of their length. Sinuosity is one of the channel types that a stream may assume over all or part of its course. In some schemes, "meandering" applies only to rivers with exaggerated circular loops or secondary meanders that is, meanders on meanders. Unless otherwise defined in a specific scheme "meandering" and "sinuosity" here are synonymous and mean any repetitious pattern of bends, or waveforms. Parameters based on mathematical formulae or numerical data vary as well, depending on the database used by the theorist.

There is not yet full consistency or standardization of scientific terminology used to describe watercourses. Over time meanders migrate downstream, sometimes in such a short time as to create civil engineering problems for local municipalities attempting to maintain stable roads and bridges. 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. Meanders of the Rio Cauto at Guamo Embarcadero, Cuba.Ī meander, in general, is a bend in a sinuous watercourse or river. Meanders develop, which lengthen the course of the stream, decreasing the gradient. The maximum gradient is along the down-valley axis represented by a hypothetical straight channel. A hypothetical stream bed following a tilted valley.
