Box 1157 Oxford, Mississippi 386551157 Some oxbow lakes in North Mississippi have water quality problems due to sediment loads from upland runoff. Fine sediment can affect the light attenuation and adsorption desorption balance thus playing an important role in the ecological cycles of lakes. Various best management practices (BMPs) may be employed to reduce fine sediment load, but methods are needed to link BMPs to improvements in receiving water quality. A water quality module was developed and integrated into a twodimensional depthaveraged hydrodynamic model, CCHE2D, which also includes a sediment transport module. The mass transport capability was first calibrated and then validated using data from two dye tests. Phytoplankton (as total chlorophyll) was simulated with inputs of nutrients, suspended sediments and related weather information. The impact of fine sediment on phytoplankton concentrations was estimated by the model. The results of a series of numerical experiments showed how the water quality in the lake could be improved due to a hypothetical sediment load reduction.
