2.5.3.1 Braided Stream

A braided stream pattern occurs when the main channel splits into a number of interconnected channels separated by islands of channel bars. Rivers which receive excessive load or which undergo a sharp decrease in gradient often become braided. Longitudinal, tranverse,and lateral bars are characteristic depositional features.

On an alluvial fan, perennial streams often exhibit a braided pattern as the sudden drop in the stream gradient causes the deposition of the larger clastic material.
