Simulation of Flow and Sediment in the Lower Coeur d'Alene River: a Demonstration

This report describes an initiative by the Idaho Department of Environmental Quality (IDEQ) to develop a demonstration of numerical modeling technology for routing of water and sediment discharge through the lower Coeur D�Alene (CDA) River. Included in this report is a brief description of the numerical model used for the demonstration, summaries of data and assumptions that went into the model setup, results from the modeling effort, and the data gaps that need to be filled in order to develop a calibrated model for the study reach. The model setup for this project is only a demonstration, but is anticipated to provide the foundation for developing a fully calibrated model that could be used as a tool for management decisions in the CDA River remedial activities
