Model Study of New Bonneville Lock

by Richard L. Stockstill, US Army Corps Of Engineers, United States,

Document Type: Proceeding Paper

Part of: Hydraulic Engineering


The filling and emptying system of the New Bonneville Lock was designed by the US Army Engineer District, Portland. The lock will be 86 ft wide by 675 ft long, with a design lift of 69.5 ft. The system proposed was of the longitudinal floor culvert type. This paper discusses test results of the model investigation including filling and emptying times for various valve speeds, pressures in the culverts, hawser forces on barges moored in the lock chamber, movement of unmoored barges in the lock chamber, and vortex tendencies at the intake vicinity.
