SEDIMENT CARRYING CAPACITY OF OPEN CHANNEL FLOW AROUND SPUR DIKE
The presence of a spur dike makes the flow structure more complex, and thus it is more difficult to determine the sediment-carrying capacity of the flow and predict the river channel evolution. In this paper, the general flow field was divided into three sub-regions according to the flow characteristics: the reverse-velocity region of the circulation zone, the positive-velocity region of the circulation zone and the main flow region according to the mean flow velocity. And the new sediment-carrying capacity formula in each of the three sub-regions is proposed based on the analysis of the mean flow velocity and the turbulence intensity. And finally the deposition or scour of the channel is analyzed.
