Filling and Emptying System, Jonesville Lock, Ouachita-Black Rivers, Louisiana: Hydraulic Model Investigation

摘要

The filling and emptying system of the 600- by 84-ft Jonesville Lock will consist of wall intake manifolds, a 10- by 10-ft longitudinal culvert in each wall, reverse-mounted tainter valves, sidewall ports, and sidewall outlet manifolds. Heads will range from 15 to 30 ft, with heads above 25 ft occurring only 5 percent of the time. The entire lock hydraulic system was tested in a composite 1:25-scale model which simulated all essential features of the prototype structure. Tests were conducted to determine the suitability of the hydraulic filling and emptying system for use at the four proposed locks of the Ouachita and Black Rivers, Arkansas and Louisiana, navigation project.
