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. These improvements are needed to meet projected future river traffic demands. A physical effects prediction model has 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 simulate ambient velocities; wind waves; diverging waves; squat and backwater generated by the tows; and propeller jet velocities and its associated entrainment velocities. Based on the calculated velocities, concentrations of suspended sediment induced by the disturbance are estimated, at the time of disturbance and after suspended sediments have been allowed to settle. Field data on tow induced velocity changes in a back channel and a tributary are also analyzed. The effects of passing recreational boats has also been measured in the main channel.
