摘要

The movement of a vessel along a waterway produces a local depression in the water surface as the flow accelerates around the vessel. These vessel-induced flows are termed "return currents." The depression around the vessel and the surge that propagates ahead of it permeate the surrounding secondary channel and backwater areas. This produces some flushing of the backwater areas and sometimes significant currents near their entrances. Knowing the magnitudes of drawdown, return currents, and flushing may on the riverbed due to vessel passage may suspend sediments, which are then transported by the river's ambient current and the vessel-generated currents, which are then transported by the river's ambient current and the vessel-generated currents. Drawdown of the water sediment-transport regions can result in short-term drying of these areas. Successful sediment-transport modeling depends on accurate predictions of water velocity's magnitude and direction. The currents at backwater entrances are sometimes significant due to the initial drawdown and subsequent reflections.
