Analysis of Design and Construction Practices in Marsh Creation Projects

This study analyzed the relationship between different factors affecting the efficiency of marsh creation projects. Through a historical analysis of completed marsh creation projects in different basins around Louisiana, it was demonstrated that there is a direct relationship between the percentage of fines in the dredge material and the volume of marsh that can be created with it. A recently completed marsh creation cell, Increment 1 of the Caminada Headlands Back Barrier Marsh Creation Project (BA-171), was also studied to better comprehend the dredge material’s behavior after placement. A combination of Cone Penetrometer Tests (CPT), vibracores, and Multi-Sensor Core Loggers (MSCL-S) was performed in carefully selected sites across the cell.
