A real-time ship simulation investigation the proposed design for deepening the man-made canal portion of the Sacramento Deepwater Ship Channel, Sacramento, CA, was conducted. The purpose of this study was to determine if the navigation channel could be deepened from 30 to 35 ft without widening from the existing channel width of 200 ft or if the channel would require widening to 250 ft as authorized. A numeric model of the existing ship channel from about channel mile 35 to the Sacramento Harbor was developed. This model was verified by a member of the San Francisco Bar Pilots Association. Numeric models of two plan conditions were also developed, one with the existing channel deepened to 35 ft and the other with the channel widened by 50 ft and deepened to 35 ft. In both plans the two bends were widened by 50 ft. Tests were run on the WES ship simulator in which six pilots from the San Francisco Bar Pilots Association conned the simulated ship through the three simulated channel conditions. These tests demonstrated that there was little difference between navigation of ships in the existing channel and in the proposed channel which was deepened but not widened in the straight reaches. Slightly but consistently better control is evident in the proposed channel. Larger bank clearances were evident with the 50-ft widening. Also, control of the ship appeared to be easier. The wider channel would provide more allowance for error, drift, and wind effects on the ships; however, the existing channel is not considered a navigation problem. Appendix B presents track plots of each pilot's runs and Appendix C presents bar charts of statistical parameters in comparison format in addition to those discussed in the main text. It is recommended that when the Sacramento Deepwater Ship Channel from mile 18.6 to the Sacramento Harbor is deepened by 5 ft (from 30 to 35ft), the straight sections can remain 200 ft wide and the turns should be widened to 250 ft.
