Book Description

An undistorted 130-scale hydraulic model was used to develop a plan for reducing hazardous conditions that affected upstream-bound river traffic in a 4-mile reach of the Columbia River just below Bonneville Dam. Before 1959, when the study was made, river traffic past Bonneville Dam consisted principally of tug-propelled log rafts and barges, but it was expected that upstream industrial development and completion of the authorized 27-ft-deep navigation channel from Vancouver, Washington to The Dalles, Oregon, would encourage use of the navigation lock by deep-draft vessels.
