Lock and Dam No. 3 will consist of a 110- by 600-ft lock and a 1260-ft-long, gated, nonnavigable dam. A movable-bed model, reproducing 12.8 miles of the Arkansas River to a horizontal scale of 1120 and vertical scale of 180, was used to determine suitability of the proposed site for the structures adequacy of proposed regulating works upstream and downstream including a proposed cutoff modifications required to provide adequate channel dimensions and safe navigation conditions with minimum maintenance and effects of various cofferdam and diversion plans. Special studies were also conducted with the model converted to a 1120 scale undistorted. Test results indicated that satisfactory navigation conditions can be developed with the lock and dam at the proposed site. Development of channel dimensions was affected considerably by the tendency of the channel to meander within the long, straight reach at the site and the effects of dam gate operation on sediment movement. Regulating structures that provided adequate channel dimensions under typical flow conditions were developed, except in the lower lock approach channel. Author
