Abstract: The low-lift locks on the Arkansas River will be 110 ft wide by 670 ft long (pintle to pintle) and will have normal lifts ranging from 14 to 30 ft. There are 15 low-lift locks at which conditions are similar enough that relatively little change in the design of the lock hydraulic system will be required at the different sites. Results of tests of the hydraulic system for these projects in a 1:25-scale model are presented in this report. Two satisfactory culvert intake manifolds were developed, a 6-port type 2 intake and an 8-port type 4 intake. The original design culvert outlet manifold which discharged into the lower lock approach performed satisfactorily. Tests of 74 sidewall port arrangements resulted in the development of five port arrangements using type A or D ports considered suitable for use at the Arkansas River low-lift projects. The type A ports are 2.54 ft wide by 3.50 ft high and the type D ports are 2.54 ft wide by 4.10 ft high. At lock 2 design conditions, 20-ft lift and 17-ft submergence (base test conditions in the model study), the recommended arrangements permit the lock to be filled in 7.5 min or less with acceptable turbulence conditions in the lock chamber and maximum hawser stresses not exceeding 5 tons. The lock can be emptied in less time with lower hawser stresses.
