Abstract : Prototype tests were conducted at Greenup Lock to investigate pressures in the filling and emptying systems of the main lock and water-surface elevations in the lock chamber. Continuous measurements were made with valve opening and closing periods of 4 and 8 min for conditions of two-culvert (normal) operation, single-culvert operation, and steady flow. The steady-flow tests yielded data concerning head loss coefficients through the lock manifolds and laterals. Discharge coefficients for two-culvert operation were also obtained. These data were compared with results obtained from the hydraulic model study. Dissimilarities between model and prototype results are thought to be largely due to dissimilarities between model and prototype designs. However the test results are believed to substantiate the validity of the model. (Author)
