Abstract: Flow velocity profile as well as sediment particle motion has been studied experimentally in steady current under various hydraulic conditions. The transition from saltation to sheet-flow mode of transport was studied from the viewpoint of flow-velocity profile characteristics. The flow-velocity profiles of the saltation dominant flow show clear difference from those of sheet-flow dominant flow. The various tendency is discussed here based on the differences in the characteristies of the sediment-particle motion of the two flow modes.
