Definition of braided stream
A braided stream consists of two or more
adjacent but interconnected channels separated by bars or an
island. They form in many different settings, including mountain
valleys, broad lowland valleys, and in front of glaciers.
Braided streams tend to form where there are large variations
in the volume of water flowing in the stream and a large
amount of sediment is available to be transported during times
of high flow. The channels typically branch, separate and
reunite, forming a pattern similar to a complex braid. Braided
streams have constantly shifting channels, which move as the
bars are eroded and redeposited (during large fluctuations in
discharge). Most braided streams have highly variable discharge
in different seasons, and they carry more load than
meandering streams. Braided streams form where the stream
load is greater than the stream’s capacity to carry the load.
