Abstract: Lock and Dam No . 14, proposed for construction on the Arkansas River, will provide a navigable pool extending upstream about 20 miles to the Robert S. Kerr Dam. The investigation, concerned with the study of navigation conditions in the approaches to the lock with the proposed design and with the development of modifications required to produce adequate channel depths and to overcome or minimize the effects of any adverse navigation conditions, was conducted on an undistorted, 1:120-scale, semifixed-bed model, reproducing about 3.4 miles of the Arkansas River and adjacent overbank area including Bruce Island and Cherokee Chute and the lock and dam structures. Results indicate that : Because of the location of the lock with respect to the bend upstream, navigation conditions for downbound tows approaching the lock would tend to be difficult and hazardous. Satisfactory navigation conditions can be developed by modification of the existing structures and realignment of the right bank upstream of the lock. Because of the training structures required to develop adequate channel depths and currents satisfactory for navigation, velocities in the reaches just upstream and downstream of the dam will tend to be high during high flows. Velocity of currents affecting navigation in the lower approach can be reduced by excavation of the channel downstream of the spillway. Shoaling in the lower lock approach will be a problem: shoaling might also occur near Wilsons Rock and in the upper approach channel, depending on flow conditions and rate of sediment movement.
