High Resolution Numerical Modeling of Cohesive Sediment Transport

Abstract

To understand the effects of spatial and temporal variability of sediment fluxes on the morphodynamic stability of intertidal flats. This study specifically focuses on numerical modeling of critical processes at small-scale (O(cm- 100m)) based on "first principles." It is proposed (1) to extend existing numerical models for cohesive sediment transport and related bottom boundary layer processes at tidal flats and wave-dominated shelves; and (2) to develop an appropriate module of floc dynamics for cohesive sediment transport; and (3) to develop appropriate parameterizations of the near bed sediment transport and bottom friction for large-scale hydrodynamic models.
