| Description: | Technical Report Abstract: 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 1:120 and vertical scale of 1:80, 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 1:120 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. A satisfactory plan for elimination of shoaling in the lower lock approach was not developed. Increasing the capacity of the ports in the upper guard wall would eliminate hazardous crosscurrents in the upper lock approach and reduce scour near the end of the upper guard wall. A fill along the left overbank would prevent overbank flow moving toward the spillway from seriously affecting downbound tows approaching the lock. In cofferdam tests, water-surface elevations along the upstream side, location of maximum scour, and scour pattern were determined together with the factors affecting these conditions.
