Abstract:

Excavation requirements, adequacy of cofferdam and diversion plans, project layout, structures designs, and proposed methods for operation of the John Day Project were investigated in a 180-scale general model. Water-surface data from the general model were used to regulate a 125-scale model in which satisfactory designs for the skeleton powerhouse units were developed. The general model was verified with natural water-surface elevations before construction of The Dalles Dam and with similar data after The Dalles pool was filled. Agreement between model and prototype flow patterns and water-surface elevations was satisfactory for both conditions.
