Abstract: The U.S. Army Corps of Engineers is investigating ways to improve lockage efficiency at the Marmet Locks on the Kanawha River, West Virginia. A physical effects prediction model have been developed to evaluate the changes on the river due to changes in future traffic patterns and tow configurations. The model has been verified based on the field measured data which cover a wide range of traffic conditions. The model consists of selected equations which predict ambient velocities; wind waves; diverging waves; squat and backwater generated by the tows; and propeller jet velocities and associated entrainment velocities. Based on the calculated velocities, concentrations of suspended sediment induced by the disturbance are estimated. Field data on tow induce velocity changes in a back channel and a tributary are also analyzed.
