  1. LCA Mississippi River Hydrodynamic and Delta Management Study (MRHDM) October 5, 2011

  2. LCA 2004 Main Report The MRHDM study is comprised of two large-scale initiatives for the Mississippi River that were outlined in the USACE 2004 LCA report: • Mississippi River Hydrodynamic Study (MRH) • Mississippi River Delta Management Study (DM)

  3. Authorization The study is authorized under Section 7003 of the Water Resource Development Act (WRDA) 2007 (Public Law 110-114)

  4. MRHDM Goal • Employ a comprehensive approach of investigating existing water and sediment resources in the Mississippi River available for coastal protection and restoration.

  5. Hydrodynamic Objectives • Design models that: • Have the ability and flexibility to model current Lower Mississippi River conditions, • Evaluate ecosystem restoration alternatives in concert with dynamic flood risk management and navigation, • Evaluate multipurpose management scenarios of the river, • Evaluate the dynamic system (specifically how changes to sea level rise, subsidence, navigation, and flood risk management would affect potential restoration alternatives.)

  6. Delta Management Objectives • Formulate alternatives that: • Consider multi-use and multi-purpose projects that involve ecosystem restoration, flood risk management, and navigation. • Arrive at a long term multipurpose project that is sustainable and meets the needs of the Nation. • This could mean changing currently authorized project purposes in the interest of arriving at a multipurpose plan that appropriately balances ecosystem, navigation, and flood risk management needs and purposes.

  7. Project Area

  8. Hydrodynamic Tasks • Data collection and management • Geomorphic analysis • Development of new small scale physical model • Development of 1D model of the Mississippi River • Development of • multi-dimensional models

  9. Delta Management Tasks • Compilation of existing information • Document existing conditions and • forecast future conditions • Ecological modeling to compare • impacts to biological resources • NEPA documentation • Restoration projects will be heavily guided by the State of Louisiana 2012 Master Plan.

  10. Next Steps • 6 and 12 month timelines including identification of tasks and potential team members • Team Kickoff Meeting soon (Fall 2011) • Preparing for Scoping Meetings (Summer 2012) • Developing Data Collection and Management Plan (2012-2014)
