Book Description
Measured hoist loads due to hydraulic downpull on powerhouse intake gates at Chief Joseph Dam were about twice as large as expected. For this reason model studies were necessary to determine the most practical gate bottom shape and the maximum hydraulic downpull to be considered when designing powerhouse intake gate hoists for Ice Harbor Project. Because prototype data were available, a typical intake, intake gate, penstock, and scroll case for Chief Joseph powerhouse were reproduced for a series of preliminary tests. The pattern and magnitude of downpull forces on the prototype intake gates were duplicated in the 1:25-scale model. Hydraulic forces on an intake gate in motion (closing) were compared with those for various openings of a stationary gate.

Book Description
Flow conditions to be expected during and after construction of Ice Harbor Dam were determined in a 1:100-scale hydraulic model that reproduced 2.7 miles of riverbed, pertinent overbank areas, successive structures, excavated channels, and disposal sites. The purposes of the model study were to check the adequacy of original designs for the project and to develop revisions if required to benefit fish passage, river navigation, energy dissipation, and power generation. Improved designs for the first- and second-stage cofferdams, fishway entrances, powerhouse tailrace, and navigation lock outlet were developed in the model. Diversion of a major portion of the river discharge through three powerhouse skeleton units would facilitate the upstream passage of fish during second-step construction. Alternative methods for operation of the completed project were evaluated. (Author).
