Abstract:

A 1100-scale hydraulic model was used to study the alignment of structures, excavation requirements, and flow conditions at Little Goose Dam. Tests of first-step construction led to relocation of the temporary fishway, use of rockfill groins along the north shore, selection of limits for disposal fills, and reductions of excavation, number of cofferdam cells, and height of embankments. The tests indicated that flow conditions during the first phase of second-step construction would be acceptable and that excavation planned for the second phase could be reduced.
