Abstract: As a result of the 2011 Greater Mississippi River Basin Flood, the 2011 Mississippi River and Tributaries (MR&T) Post Flood Report (USACE 2012) highlighted the need to conduct a flowline assessment for the MR&T system. This assessment was to include data from the 2011 flood event and any physical, hydrologic, or hydraulic changes that had occurred in the river system to determine if a change in flowline or water control plans was warranted. The U.S. Army Corps of Engineers, Mississippi Valley Division (MVD) Commander at that time, MG John Peabody, also emphasized the need for an objective re-assessment of the flowline and meteorological conditions associated with the 1955 “Hypo Flood.” Based upon this guidance, the flowline assessment was initiated in 2014 to address the issues outlined in the Post Flood Report along the main stem and to assess the Refined 1973 Flowline. This Technical Note is a summary of the Mississippi River and Tributaries Flowline Assessment Main Report (USACE 2018a). The assessment is intended to determine if the Hypo Flood associated with the currently authorized Refined 1973 Flowline (USACE 1978) is still sufficient; how the flowline has changed due to changes in river conditions; how the flowline changes utilizing updated technology and methods; and how the computed flowline compares to existing levee heights.
