This report documents an investigation of the hydraulic effects of dikes on water levels in the Mississippi River between Natchez, MS, and Baton Rouge, LA, conducted for the U.S. Army Corps of Engineers, Mississippi Valley Division, Vicksburg, MS. The investigation was conducted using a previously calibrated Natchez-to-Baton Rouge Adaptive Hydraulics numerical model. The objectives were to alter roughness and height variables associated with the dikes and overbanks encompassed in the numerical model and evaluate their effects on water surface elevations. This academic exercise provides an indication of the relative level of impact associated with modifications to the dikes and overbanks for this portion of the Mississippi River and does not represent future plans or recommendations by the U.S. Army Corps of Engineers. Steady flow simulations were simulated for 12 May 2011 to investigate the variation in model results during the peak of the 2011 flood on the Mississippi River.

AbstractThe U.S. Army Corps of Engineers (Corps) is a project-oriented agency with multiple national missions under its Civil Works program including navigation, hydropower, flood risk management, ecosystem restoration, water supply, regulatory authority for wetlands and U.S. waters, recreation, and disaster preparedness and response. The Corps ocean and coastal activities revolve around the design, construction, and maintenance of specific projects such as channel dredging, coastal protection, beach nourishment, and harbor construction, all requiring research, modeling, and observations. Several Corps activities contribute ocean observations to the Integrated Ocean Observing System (IOOS®) and have requirements for existing or planned IOOS observations. Collected observations include long-term coastal wave climate, water levels, and coastal mapping data information. These provide project-specific and regional data that are used to develop and verify numerical models which are extensively used in project design and to evaluate project costs, benefits, and associated risk. An overview of the Corps coastal activities, data collection, and modeling programs is provided along with information regarding how IOOS coastal and ocean data are being used by the Corps.

This article discusses measures being taken by the U.S. Army Corps of Engineers to protect New Orleans from future flood events. The U.S. Army Corps of Engineers is redesigning and upgrading the 350-mile network of linked levees, floodwalls, gates, and pumps in the New Orleans area. The Corps of Engineers’ plan for New Orleans flood control involves upgrading some existing structures such as levees and floodwalls and adding some new risk-reduction features, two of which are movable gates. The proposed Bayou Bienvenue Gate will sit near the junction of the Gulf Intracoastal Waterway and the Mississippi River Gulf Outlet to keep floodwater away from the southern end of the Industrial Canal. The Seabrook Gate will span the northern end of the Industrial Canal where it meets Lake Pontchartrain. By preventing storm surges from entering the Industrial Canal, these gates will protect a densely populated residential and commercial area. However, the presence of the new gates will change day-to-day current patterns in ways that could impact existing structures and use.
