The filling and emptying system of the 1200- by 75-ft Old River Lock will consist of wall intake manifolds a 13.5- by 13.5-ft longitudinal culvert in each wall reverse-tainter, multispeed culvert valves side-wall ports and a bottom lateral discharge manifold. Normal heads will range from 5 to 15 ft, with a maximum probable head of 32 ft. The entire lock hydraulic system was tested in a composite 125-scale model, simulating all essential features of the prototype structure, to determine a adequacy of intake and discharge manifold designs b maximum permissible lock-filling and -emptying rates at which turbulence and hawser stresses would not be dangerous c best location and spacing of side-wall ports and d best location of the bulkhead slot below the culvert filling valves.
