| dc.description | Abstract: Ozark Lock and Dam will consist of a 110- by 600-ft lock and an 890-ft-long, gated, nonnavigable dam. A 1:120- scale, fixed-bed model, reproducing 2.7 miles of the Arkansas River, was used to: (A.) demonstrate flow conditions in the lock approaches; (B.) measure the distribution of flow across the model at the axis of the dam for a number of flows; and (C.) assist in developing modifications of the approaches and structures to improve navigation conditions. Tests were concerned with the study of flow patterns, measurement of velocities in the lock approaches, and behavior of a model tow on entering and leaving the lock. The results of the investigation indicated the following: Modifications of the original design would be required to develop satisfactory navigation conditions in the lock approaches. Excavation for the entrance to the powerhouse can be reduced and flow distribution into the powerhouse can be improved by realignment of the upstream bankline. Sudden powerhouse releases could produce conditions hazardous to navigation and some limitation should be placed on the rate of increase in powerhouse discharge. The maximum head differential on the downstream lock gate during lock emptying could be as much as 0.6 ft during the higher flows. | - |
