The most pertinent is the reduction of the diameter of the hollow-cone valve from 36 inches to 30 inches. This change reduces the capacity of the outlet works from 400 cfs to 230 cfs. However, the final geometry tested will still be satisfactory as long as the location of the apex of the valve cone remains the same with respect to the baffle walls, so that the trajectories intercepted by the surrounding chamber walls remain unaltered. Another change involving the outlet works is the reduction of the capacity of the bypass from 170 cfs to 750 cfs. This change is minor, however, and need not affect the chamber dimensions.technical reportsengCopyright and other restrictions may apply. User is responsible for compliance with all applicable laws.
