Joint T&DI Louisiana, COPRI Louisiana and ASCE Acadiana Branch May Event

Mississippi River Navigation + Marsh Restoration

Different Goals; Common Solutions

Please join us in Lafayette for Mississippi River Navigation + Marsh Restoration; Different Goals; Common Solutions - a joint T&DI and COPRI Louisiana Chapter presentation. Presentation to be followed by a complimentary crawfish boil.

The U.S. Army Corps of Engineers (USACE) has devoted considerable effort to maintaining navigation along the Mississippi River.  The importance of river commerce cannot be overstated.  Therefore dredging operations occur nearly non-stop from the mouth of the River past New Orleans, up to Baton Rouge and beyond.  The improvements currently underway at the Panama Canal will only increase River traffic.  

At the same time, tons of silt and sand are bypassing the adjacent marsh land.  The coastal wetlands are subsiding and the loss of critical marsh land negatively affects both commercial fishing as well as its ability to provide natural buffering against storms. The obvious solution is to divert the dredge spoil and let it nourish the starving marsh.  Our two speakers will discuss why the obvious solution is not a simple solution, and if done incorrectly could severely damage existing River infrastructure.

Attendees to this event will be provided with 2.0 PDHs.

SPEAKER Information

Nancy Powell, P.E., USACE, New Orleans, LA

Steve Dartez, Coastal Engineering Consultants, Baton Rouge, LA

Gregory Grandy, Coastal Engineering Consultants, Baton Rouge, LA

Nancy Powell, P.E., D.WRE is Chief of the Hydraulics and Hydrologic Branch of the Army Corps of Engineers, New Orleans District.  During her 32-year career with the Corps, she has worked on a wide variety of navigation projects, as well as flood control, hurricane protection, and environmental projects.

Steve Dartez is a Project Manager with Coastal Engineering Consultants (CEC) for the Scofield Island Project where Mississippi River sand is being mined for the restoration of the island.

Gregory Grandy, Senior Environmental Manager for CEC, will co-present with Mr. Dartez on the Scofield Island project.

Our speakers will explore projects and studies associated with the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) and Louisiana Coastal Area (LCA) that utilize Mississippi River sediments for marsh restoration.  The discussion will address the engineering challenges associated with dredging, and the identification, excavation, transportation and placement of dredge sediments suitable for marsh restoration.  The presentation will close with a discussion of the successful Scofield Island project.
