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.
