The ambient velocity and the changes of velocity due to barge traffic are being continuously measured with time at three distances from the shore on one side of the Illinois River near McEvers Island. The analysis shows that the maximum turbulence shear stress generated by the changes of velocity due to barge traffic is significantly higher than that for the natural flow in the river. Movement of barge traffic in the upstream or downstream direction produces more transverse turbulence shear than the natural river flow. 收起
