The flow structure on the sand bars, containing both sub-critical flow and super-critical one, was examined by laboratory experiments and numerical analyses, focusing on the effects of riverbank roughness and riverbed topography. It was shown that the riverbank roughness decelerates the flow along riverbank, which accelerates the flow of the central part of the channel. Then, the flow is super-critical in the center part of the channel and is sub-critical near the riverbank, which was correctly predicted by the numerical analysis. Numerical simulation also clarified that the position of maximum velocity changes downward as the plane angle of sand bar front becomes large. It was suggested that the influence of riverbed must also be taken into consideration in the case of bank revetment.
