Carry out an exploratory study of bottom sediment erodibility in the muddy northern half of Chesapeake Bay. Compare and evaluate two state-of-the-art techniques for measuring erodibility to ensure high data quality and to investigate potential differences in results. Analyze the data in the context of a newly developed erosion formulation that allows application of results for numerical sediment transport modeling and accounts for a potentially limited supply of erodible sediment. Relate seasonal and spatial changes in erodibility to environmental factors such as grain size distribution, sediment water content, recent sedimentation rate, biological activity, and water quality.
