Dardanelle Lock will be 110 ft wide by 670 ft long and will provide a maximum lift of 54 ft. Results of model tests to determine the suitability of a longitudinal floor culvert filling and emptying system for the lock are presented herein. The recommended system includes intake manifolds in the approach walls, a 14.5-ft-wide by 13-ft-high culvert in each wall, a lateral crossover culvert at the midpoint of the lock leading to four 15-ft-wide by 8-ft-high longitudinal floor culverts, and culvert outlets located riverward of the lock in a common basin. Each floor culvert has nine pairs of 1.57-ft-wide by 4-ft-high side ports spaced 16 ft on centers, resulting in a port-to-culvert area ratio of 0.94. The port manifolds in each end of the lock cover 19 percent of the chamber length and are centered at the upstream and downstream quarter points of the lock chamber. Baffles were used along the center line of the lock and along lock walls opposite port manifolds. Author
