Book excerpt: Lock and Dam No. 9, proposed for construction on the Arkansas River, will provide a navigable pool extending upstream about 25 miles to the lock and dam at Dardanelle (Lock and Dam No. 10). The model investigation was concerned with the study of navigation conditions in the approaches to the lock to determine the adequacy of the proposed design and with the development of measures to overcome or minimize the effects of any adverse conditions. An undistorted 1:120-scale model, reproducing approximately 6 miles of the Arkansas River and adjacent overbank area near Morrilton, Ark., including the lock and dam structure, was used for this investigation. The investigation indicated that conditions in the approaches to the lock with the original design would tend to be difficult and hazardous. Satisfactory navigation conditions could be developed in the upper approach with excavation of the right bank above the lock and submerged dikes to reduce the velocity of currents in the approach. Navigation conditions in the lower approach could be improved by providing sufficient maneuver area for downbound tows to move away from the right bank against the currents moving toward the bank. Construction of a wing dike or extension to the lower guard wall would provide the additional protection and maneuver area required. Streamlining the end of the upper guard wall would reduce the disturbance to flow near the end of the wall and improve the distribution flow through the gated spillway. (Author).

This book was released on 1963 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of the studies for development of a navigable waterway from the Mississippi River to the general area of Tulsa, Oklahoma, a movable-bed, distorted scale model of a typical 5-mile reach of the Arkansas River was used to study problems involved in the location, design, and operation of a lock and dam on an Arkansas River bend. Principal conclusion were: (a) The lock and dam should be placed as far downstream of the point of the convex bar as possible to minimize crosscurrents and scouring in the upper approach. (b) Ports will be required in the upper guard wall of the lock to reduce the intensity of the crosscurrents near the end of the guard wall. (c) Shoaling in the lower lock approach, which would tend to be heavy, could be reduced by a wing wall at the end of the lower guard wall. (d) There is no appreciable difference between a stepped-sill and a level-sill dam insofar as the movement of sediment is concerned. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Fort Smith reach of the Arkansas River, located in the Lock and Dam No. 13 pool, includes the mouth of the Poteau River and is crossed by two bridges 850 ft apart. An undistorted 1:120-scale, semifixed-bed model reproducing approximately 4 miles of the Arkansas River and adjacent overbank and the lower 2 miles of the Poteau River was used to determine the regulating structures and modifications required to develop a channel of project dimensions, and the modifications required to the existing bridges to provide satisfactory navigation conditions through the reach.
