Movement of barge traffic (barge tows) in restricted waterways such as the Illinois or Mississippi Rivers can generate rapid return flows and water-level depressions (drawdown) between the barge and the shoreline. Due to this return flow, velocity distribution in the zone between the barge and the shore changes temporarily in space and time. The return velocity and the drawdown generated by barge traffic depend on many factors, including river width and depth, barge characteristics, tow speed, draft, and lateral distance from the barge to the shore. An overall mathematical modeling concept of the lateral variation of return flow due to navigation traffic is discussed in the paper.
