dc.description.abstractThis report describes the formulation of the SEDZLJ sediment transport model, coupling of the model with the ICM eutrophication model, validation of the combined codes on a simplified grid, and application of the combined codes to a prototype system. The code validation tests indicate the codes are correctly coupled. The combined codes meet specified performance criteria including: 1. Mass conservation in water and bed. 2. Limited sensitivity to variations in model time-step. 3. Settling of new ICM state variables through model water column agrees with settling of original ICM state variables. 4. Transport of new ICM state variables agrees with transport of original ICM state variables. 5. Sediment bed will armor. 6. Bed erodes away smoothly. 7. Model behaves reasonably for accumulation in the bed with no erosion. Additional evaluation and testing were performed through application of the combined models to a prototype system: Lake George, Florida. The codes perform reasonably through a three-year simulation. The tests indicate, however, that realistic application of SEDZLJ requires an extensive set of field and laboratory observations.en_US
