|Abstract:||The flowline assessment was undertaken to review the current Mississippi River and Tributaries (MR&T) flowline on which the project design levee elevations are based. The assessment was initiated in 2014 to address the issues outlined in the MR&T 2011 Post Flood Report. Evaluations were to not only consider the hydrology and hydraulic conditions of the system today but were to consider any other factors that would impact the flowline over the next 50 years. To assess the flowline, a seven step process was utilized: (1) develop precipitation amounts; (2) calculate the amount of runoff; (3) calculate the amount of flow in the river from the runoff, both for regulated and unregulated conditions; (4) calculate a water surface profile/elevation with appropriate levees, structures, backwater areas, and floodways assumptions; (5) develop estimates for future degradation/aggradation of sedimentation at various locations, climate change, loop effect, sea level rise, and subsidence, all of which would affect the water surface profile; (6) analyze water surface profile estimates to identify areas of concern; and (7) perform District Quality Control Review, Agency Technical Review, and Independent External Peer Review on all of the above steps to ensure quality.|
