Description of Requirement

Salinity Intrusion Physical Model Supplies

Title: Salinity Intrusion Modeling Effort

Background:

The Coastal and Hydraulics Laboratory (CHL) located within the Engineer Research and Development Center (ERDC), Vicksburg, MS supports other programs, agencies and missions with the assistance of DPW (Directorate of Public Works) in building physical models to meet critical mission research, design validations, discover any issues that may arise within the design and/or develop any possible required solutions to mitigate challenges facing a particular structural improvement or new structure being developed. This Salinity Intrusion Modeling Effort material will support a physical model performing the abovementioned tasks.

Objective:

This supply request is critical for the Salinity Intrusion Physical Model. There have been critical moments over the last 3 years in which the salt wedge has migrated dangerously close to New Orleans up the Lower Mississippi River during low water events. The ERDC supports the modeling effort to better understand potential mitigation strategies such as an augmented sill. Failure to arrest the salt wedge before reaching New Orleans’ water supply would be catastrophic.
