RETURN FLOW IN RIVERS DUE TO NAVIGATION TRAFFIC. TECHNICAL NOTE

Movement of navigation traffic, such as barge-tows, in restricted waters can create rapid return flow and water-level depression between the barge and the shoreline. The velocity distribution in this zone, then, changes temporarily in space and time. Methods frequently employed to calculate the return-velocity distribution predict an exponential velocity distribution that decreases laterally with distance from the barge. Based on field data, though, current models do not exactly represent field conditions. The aim of this paper is to use existing models to calculate the average return flow and the lateral return flow distribution, and compare them with the observed data to test the validity of these models.
