Mississippi River Hydrodynamic and Delta Management (MRHDM) Study

The U.S. Army Corps of Engineers and the State of Louisiana’s Coastal Protection and Restoration Authority Board (CPRAB), have initiated the Louisiana Coastal Area (LCA) Mississippi River Hydrodynamic and Delta Management Study.  The Mississippi River Hydrodynamic and Delta Management (MRHDM) Study is the first large-scale, long-term restoration assessment investigated under the LCA Program, as authorized under Section 7003 of the Water Resource Development Act (WRDA) 2007.  This study will identify and evaluate a combination of large-scale management and restoration features to address the long-term sustainability of the lower Mississippi River Deltaic Plain, and will balance the interests of ecosystem restoration, flood risk reduction and navigation.
