Description
Summary:An extensive series of physical model investigations was conducted during the late 1950's and early 1960's to develop plans for reducing maintenance dredging costs for Savannah Harbor. The plan developed involved dredging a sediment basin at the lower end of Back River, construction of a tide gate in Back River, dredging a connecting canal between Back River and Middle River, and channel improvements in the upstream portion of Back River. As the plan was being implemented, questions arose that required a reanalysis of the impact of the plan on salinities in Little Back River. Numerical models, flow and salinity, were developed and applied to the channel network above Fort Jackson to estimate salinity levels at the location of the freshwater intake for the wildlife refuge adjacent to Little Back River. Computations for preproject conditions and with the plan fully implemented indicted relatively small salinity increases at the location of the intake. The computations also indicated that should these small increases prove detrimental, further improvements in the back channels could increase the freshwater inflow to the back channels. Appendices A and B of the report discuss the hydrodynamic and salinity models, respectively, used in the investigation. (Author) See also Volume 3, Section 5, AD-724 931.
