This book was released on 1965 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted on a 1:25-scale model of the 86-ft-wide by 675-ft-long navigation lock chamber, hydraulic system, and approaches. Minimum, average, and maximum lifts for the lock are 62.8, 83.6, and 90.5 ft, respectively. Model tests on elements of the original design lock showed that improvements were needed. Vortex action extended through the intake and filling culverts and created an explosive discharge within the lock chamber. With an initial head of 90.5 ft, the lock filling time was 12.0 min, emptying time was 15.8 min, and maximum forces on barge tows moored within the lock chamber were 15.7 tons. The maximum forces, which occurred about 1 min after the filling valves began to open, indicated that the initial phase of valve motion was too rapid. Strong eddy action and maximum velocities greater than 10 fps showed that improved distribution of lock outflow into the downstream approach was required.

This book was released on 1966 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1955 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general purpose of the model studies of the McNary navigation lock was to provide hydraulic information and data for the development of an efficient and economical design for the lock hydraulic system. Investigation of the problems involved in the study of the lock hydraulic system indicated that two models would be required for complete model analysis: a comprehensive model of the entire lock and hydraulic system constructed to a model-to-prototype scale ratio of 1:25 (called the lock model); and a sectional model built to a scale of 1:20 (designated the valve model) to isolate and study the lock tainter valves. The occurrence of negative pressures downstream from and adjacent to the tainter valves was the subject of a vacuum-tank study at the Waterways Experiment Station. These tests were conducted on a tainter valve of the same scale ratio used in the valve model.
