Abstract : 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)
