Summary:With the aim of creating navigational channel and river bank stabilization using bandals, flow structures, suspended sediment transport pattern and bed evolution around them under live-bed scour condition were investigated in the laboratory experiment where ten pairs of such structures were installed on both sides of channel banks. The measurements were taken in dynamic equilibrium state of the experiment. A 3D numerical flow model based on unstructured mesh was developed. The model can simulate the flow structures in experiment reasonably well.
