Abstract:

Prototype measurements made at Beltzville Dam were of special interest in that a the prototype is very similar in design to the model which received extensive testing prior to prototype construction b the long, straight conduit approximately 178 diameters lent itself to the development of a uniform gradient and c a slug-type flow known as burping had been experienced at the project. Tests were conducted in the 7-ft-diam flood-control conduit and in the water-quality control intake structure. Measurements included a Hydrostatic pressures at seven piezometer pairs along the conduit, b pressure fluctuations in the conduit transition zone and downstream of the water-quality control gate, c air demand downstream of the control gates, d impact pressures in the water intake tower, e pressures in the converging vertical bend at the base of the wet well, and f high-speed motion pictures of the slug flow at the outlet portal. Good agreement was found between the comparable model and prototype data.
