CORP of Engineers Mat Casting Yard Protection Levee
St. Francisville, Louisiana

Levee Overtopping/Demonstration Project

Description of Test:

The New Orleans Corps of Engineers placed Shoreblock SD on the levee surrounding their mat casting facility located on the Mississippi river as a test section. This test section by the U.S. Army Corps of Engineers New Orleans District in St. Francisville, La was to evaluate constructability, vegetative characteristics, potential maintenance issues and ultimately erosion control on future levee armoring projects.

Test:

Subsequent to the establishment of vegetation and successful execution of planned maintenance investigative activities, the Mississippi River achieved above normal flood stages overtopping the containment levee for three hours at the demonstration site, exposing the Shoreblock mats to substantial overtopping flow.

Result:

"We are very satisfied with how well the matting has held up under the extreme weather conditions and flooding that have since occurred on the levee," stated Bruce Harrel of B&P Enterprises and Resource One Nursery. This test will assist the CORP of Engineers to evaluate the use of ACBs for armoring including plans to prevent levee failures in Southern Louisiana.
