Abstract: The Kate Aubrey reach of the Mississippi River, located north of Memphis, TN, was used as a test domain for the ADaptive Hydraulics (ADH) sediment transport routines. This 27.4 km (17-mile) stretch of river experiences times of wetting and drying and contains several nonerodable dike structures and revetments. This reach is a good test condition for a model since there are two dike configurations in its history, one that did not maintain a navigation channel and a second that, for the most part, did maintain a navigable channel. This results in a clear way to test the suitability of a model. Tests included single and multiple grain sizes for steady-state and 3-month hydrograph runs. ADH results correctly identified navigation shoaling problems in the first dike configuration and an essentially good navigation condition in the second. A description of the sediment equation implementation in the two-dimensional (2-D) shallow-water module of ADH is given in this System-Wide Water Resources Program (SWWRP) Technical Note as well as the results and qualitative conclusions for the various Kate Aubrey river morphology simulations that were conducted.
