Morphodynamic evolution of a lower Mississippi River channel bar after sand mining

This paper reports the results of an investigation on the relationship between sediment supply, borrow-pit flow hydrodynamics, and borrow-pit infilling within a lower Mississippi River (LMR) channel bar in Louisiana, USA using both field-based and numerical methods. An improved understanding of infilling patterns and rates enhances the ability of river engineers and managers to predictively model how a river channel bar will respond to mining-related disturbances and to schedule future dredging accordingly.
