Abstract:

This report documents the development of the model for the Mississippi River and Tributaries Flowline Assessment using the Hydrologic Engineering Center - River Analysis System model unsteady, version 5.0.1 completed by the U.S. Army Engineer District, Memphis the U.S. Army Engineer District, Vicksburg the U.S. Army Engineer District, New Orleans and the U.S. Army Engineer Research and Development Center, Vicksburg, MS. The 2011 Mississippi River flood was chosen as the primary event for calibration, and the model performance was checked for 2002 and 2008, two other recent high-flow events. The model from this effort was used for two simulations of historic project design flows PDFs, here labeled Historic PDF - Existing Yazoo and Historic PDF - Authorized Yazoo. The combined model was also used for 10 new hypothetical project design flows. Additionally, the model was used for one alternative scenario, labeled Concept Plan. Future sea level rise was also implemented with the Concept Plan and the New Hypo 58A-R PDF simulations.
