The Mid-Breton Sediment Diversion Program is an effort to accomplish a goal of the State’s Master Plan for a Sustainable Coast. The project is being designed to divert sediment-laden Mississippi River water into the Breton Sound Basin by re-establishing a connection between the River and the Basin to build, sustain and maintain land.
Delta Coast Consultants is a member of the design team that was awarded the Mid-Breton Sediment Diversion Project by CPRA. With Stantec serving as the prime, DCC is responsible for all field survey and data collection. DCC collected topographic and bathymetric data as well as performed event based ADCP measurements to obtain river flow characteristics. This effort also includes designing and deploying instrumentation in the river and in the receiving basin to provide accurate sediment load data and hydraulic characteristics for hydraulic model calibration during design.
Instrumentation installed includes Teledyne Acoustic Doppler Current Profilers (ADCP) to measure water velocity and particle backscatter as well as In-Situ Sondes to measure Conductivity, Temperature and Depth (CTD) at pertinent hydraulic locations. The deployment of the instrumentation in the Mississippi River carries unique challenges, and the team designed an anchored buoy system that would locate the instruments appropriately in the water column to produce the most valuable data. Delta Coast is integral to the design and deployment of these systems and manages all data collection and processing prior to data utilization for modeling.
