Abstract : The following report presents the initial phase of research under the Navigation Systems Research Program work unit Modeling Lock Approaches. The objective was to provide an effective method of computing current magnitudes and directions at lock approaches for open river conditions. The meshes were developed using the Surface-water Modeling System. The two-dimensional, depth-averaged numerical flow solver Adaptive Hydraulics was used to run the simulations. Eighty-seven of the one hundred thirty-one U.S. Army Corps of Engineers (USACE)-maintained lock and dam projects were modeled during this research effort, which represent the structures with the highest priority in each of the twelve USACE districts located in the Mississippi Valley. Models were developed using a wide range of sources for data that included USACE districts, design memoranda, the United States Geologic Service, and water control manuals.
