Pagination or Media Count:
Tests were conducted to make a comprehensive prototype evaluation of the postmodification i.e., aerator installation and air vent streamlining operating conditions of the project. Prototype measurements included air vent discharges, center sluice aerator slot pressures, and invert pressures acting along the center line of the center sluice. Pressure drops from the atmosphere to the right and center sluice gate chambers were measured along with the pressure acting on the modified wall separating the center sluice gate chamber from the lower service gallery. In addition, vertical, transverse, and longitudinal structure accelerations were measured in the vicinity of the center sluice gate and on the sluice emergency gate during an emergency gate lowering operation.
