Book excerpt: A 1:24 Froude-scale model of the proposed Lake Chicot Pumping Station was constructed and utilized to identify and to correct hydraulically objectionable features of the flows in the pump sumps. The model tests showed that the flows from the plant forebay generally enter the individual pump bays with a strong transverse component of velocity and produce an intense captive eddy on the lee side of each pump-bay partition wall. The transverse velocity resulted from geometric constraints imposed on the plant configuration. In order to achieve better pump approach-flow conditions trash racks with relatively deep vertical bars which functioned as turning vanes were proposed. A 1:10-scale sump model then was built to test for model-scale effects in the trash-rack tests, and an extensive study was conducted to obtain an improved sump configuration which would minimize any vortex-related problems in and around pump suction bells. The modified sump configuration has small clearance between the pump bell and sump back-wall; converging sidewalls; and a floor mounted splitter plate (vortex breaker) beneath the pump. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The model study reported herein was conducted to evaluate the gravity-flow and pump outlet discharge characteristics and the size and extent of stone protection required in the exit channel. The study indicated the need for minor modifications to improve flow characteristics in the approach to the gravity-flow section and in the stilling basin. The major problems encountered were generated by adverse entrance conditions to the gravity-flow section with both free and submerged flows. Satisfactory approach flows were obtained by excavating a portion of the approach channel immediately upstream from the structure and streamlining the gravity-flow abutments. The improved flow conditions eliminated the adverse drawdown at the abutments and provided a more uniform flow distribution in the stilling basin. The stilling basin was modified to permit more efficient energy dissipation by moving the original row of baffles downstream and adding a second row of baffles. Tests also indicated that the apron length could be reduced by 12 ft without significantly affecting stilling basin performance. The model tests indicated that an 84-ft length of riprap with a maximum stone weight of 292 lb located downstream from the stilling basin would remain stable under expected flow conditions with the recommended stilling basin design. The hydraulic performance of the pump discharge outlets was satisfactory for the range of anticipated flow conditions.
