On a physical model, an experimental study has been carried out to study the flow turbulence and morphological characteristics in an asymmetric sinuous channel. Velocity distribution shows no evidence of outer bank cell of secondary flow. Streamwise turbulence intensity is more dominating than transverse and vertical turbulence intensity. Bursting events are quantified by octant analysis, which reveals that the internal ejections and external sweeps are prominent. There is a significant role of internal ejection, external sweep events, and helical flow in forming erosion and deposition zones. The transition probabilities of movement states that stable organizations of events are the most possible movements, whereas cross organizations of events have the least possible movements. The morphological changes at all cross sections shows deposition near the inner bend and maximum erosion near center at the bend apex, progressing towards the outer bend. Moreover, the deposited sediment bar at the inner bend promoted flow separation over the point bar. Topographic steering of the flow induces reasonable variations in the redistribution of flow velocity. As the study provides insights into the flow turbulence and morphological characteristics in an asymmetric sinuous channel, it will be a beneficial help to engineers for planning hydraulic structures.
