Abstract:

The combined effects of subsidence and erosion have caused encroachment of Lake Borgne toward the Mississippi River-Gulf Outlet MR-GO canal. The shoreline erosion poses the potential to alter the general circulation patterns in the areas and increase the channel maintenance requirements in MR-GO. Mathematical models were developed for the simulation of hydrodynamics and sediment transport to evaluate the potential changes in sedimentation. The numerical model was verified to hydrodynamics for three separate events, each with considerable degree of meteorological contamination. The sediment transport verification to the observed suspended sediment concentrations and the channel shoaling rates was initiated. The final sediment transport verification was not achieved as the project was terminated due to revised costs associated with the proposed bank line protection construction. This report documents the work performed toward the original study objectives.
