Our team constructed and tested two 1:65 scale live-bed physical models of the proposed Mid-Barataria Sediment Diversion and the conveyance channel. The project is part of the Coastal Protection and Restoration Authority of Louisiana (CPRA) $2.2 billion plan to construct the 2-mile long Sediment Diversion to divert muddy Mississippi River water into Plaquemines Parish’s degraded wetlands to rebuild land. The hydraulic modeling and testing performed provided important design information related to sedimentation, riprap stability, coffer dam construction, gate testing and other key design parameters to make this concept a reality. Project construction commenced in August 2023.
