Abstract
The Louisiana Gulf Coast is a dynamic system of heavy influence on the cultures that live and prosper around it. Land in this area is in jeopardy of being lost. In 2017, the Coastal Protection and Restoration agency will issue a new State Master and this thesis provides a more intricate way of numerically predicting the behaviors of associated sediments. A model for the estimation of resuspension and deposition is proposed and prepared for integration into the existing model. The silt and clay fractions of the bed sediment and the sediment inflow were modeled by the widely used hydrodynamic models of Delft3D and ECOMSED, using the Young and Verhagen wave properties to obtain orbital velocities and bed shear stress. The critical shear stress for erosion was based on empirical formulas developed by van Rijn.
