A known discharge, uncoupled, sediment routing model, KUWASER has been developed. The model sequentially solves the steady flow and sediment continuity equations. This procedure allows for efficient solution of sediment routing problems on large river systems. The model can perform backwater calculations and sediment routing in main stem and multiple tributaries including divided flow reaches. The user can determine river response to river management practices such as channel improvement, realignment, dredging or tributary modifications. The model was tested against two other models, a stage-discharge relationship and a fixed bed model by comparing the frequency of model errors in stage prediction. A sensitivity analysis was performed to determine the sensitivity of the models results to variations in six input parameters. The Yazoo River Basin in Mississippi was used as a case study to demonstrate the model capabilities. The model can be an effective tool in the prediction of river response.
