Description: Technical Report
Abstract: This report presents results of tests that were conducted to determine valve loss coefficients to use in predicting pressures downstream from navigation lock culvert valves. Reliable prediction of these pressures is needed so that a valve can be sited to prevent cavitation either by submergence or self-aeration with air vents. Tests were conducted with various culvert roof expansions beginning at several locations downstream from the lock culvert valve to determine the effect of the expansion on valve loss coefficients.
