Description :
Direct measurement of three-dimensional flow fields and morphological evolution of the anabranches in the braided Brahmaputra-Jamuna River, Bangladesh, were undertaken to investigate the interactions between fluvial processes and anabranch morphology. These data were used to elucidate the circumstances leading to the bifurcation of a single channel, with a topic of fundamental importance to understanding the physical processes responsible for braiding. An empirical relationship was established to discriminate between channels with single and multi-thread velocity fields.
