| Abstract: | The purpose of this appendix is to present the results of the engineering studies, investigations, modeling, and analyses conducted to develop the recommended project improvements for the Bar Channel, Bay Channel, Choctaw Pass Turning Basin, and a portion of the River Channel of the Mobile Harbor Federal Navigation Project. Engineering evaluations were performed for channel deepening and widening measures up to the fully authorized dimensions of the three channel segments. The turning basin was also evaluated to determine its adequacy in accommodating the selected design vessel(s). Detailed efforts included (1) a geotechnical investigation to characterize the subsurface conditions; (2) hydrodynamic, water quality, sediment transport, and groundwater modeling to characterize the physical conditions and processes of the study area and determine the relative changes due to widening and deepening the navigation channel; (3) a vessel generated wave energy assessment to quantify the relative changes in wave energy due to vessels calling the port in the future, with and without the proposed channel modifications; (4) a feasibility level ship simulation study to evaluate channel width for one-way traffic, turning basin dimensions, bend easing widths, and lengths and widths for a portion of the channel for two-way traffic; and (5) cost estimating to identify the total project costs for all alternatives considered. The details of these efforts and other supplementary engineering assessments are discussed in this appendix. |
