Abstract: A HEC-6T numerical model of the entire Lower Mississippi River between the end of Southwest Pass and the confluence of the Ohio River was developed. The model, which included over 1000 river miles, was calibrated to 1991-2002 measured data. The purpose of the numerical sedimentation model was to provide a tool to evaluate the long-term and system –wide effects of specific Mississippi River and Tributaries Project features. Model applications related to the effects of sediment diversions and the effects of dredging in the New Orleans District were demonstrated. The model demonstrated the effects of new constrictive works on the long-term and short-term river morphology. The model was used to test the effects of changes in upstream sediment inflow. The model’s ability to assess the effects of natural geomorphic changes, such as erosion of hard points, was demonstrated. Future application of this model to specific project sites should include the addition of more detailed geometry in the area of interest.
