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.
