Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted on two different 1:25-scale models of the New Bonneville Lock located on the Columbia River in Oregon. The lock models were built to study the filling and emptying systems, which consisted of designs utilizing bottom longitudinal floor culverts. The first design studied, designed as the H-H pattern system, consisted of four longitudinal flood culverts in each end of the lock chamber. The second system studied had two longitudinal floor culverts in each end of the lock chamber and was designed as the H pattern system. In the H-H pattern system, the filling culverts, which were located under the lock chamber floor, connected to a crossover culvert with a horizontal splitter wall dividing the flow to upstream and downstream splitter manifolds were equal divisions led into four longitudinal flood culverts in each end of the lock chamber. With the type 6 (recommended) design and a 1-ruin valve opening time, the lock chamber filled in 8.7 ruin and emptied in 12.1 ruin. Due to differences in friction losses, the prototype can be expected to fill and empty about 20 percent faster than the model (7.0 ruin and 9.0 ruin, respectively). Modifications involving installing a slope in the lower sill and a v-notch design in the high sill were significant factors that resulted in fast filling and emptying times, low hawser forces, and only minor movement with various tow arrangements for different operating scenarios.

Available in PDF, EPUB and Kindle. Book excerpt: The navigation system currently in use at Bonneville Locks and Dam, Columbia River, was placed in operation in May 1943. Navigation problems have resulted in damage to the guide wall and the wing wall of the lock. A new 86-ft- wide by 675-ft-long lock has been proposed for construction immediately south of the existing lock. It was recognized that major channel modification 5 could be necessary to develop satisfactory navigation conditions for tows using the new lock. This report documents a comprehensive model study that was conducted to investigate conditions that could be expected with the proposed design and to develop the modifications required to ensure satisfactory navigation conditions. The effects of various plans and modifications on water-surface elevations and current directions and velocities were studied, as were the effects of the resulting currents on model towboat and tow behavior.
