Integration of an Analytical Model for Shelf Sediment Deposition into SedFlux

The Final STRATAFORM Modelers Meeting identified critical steps required to achieve an integrated continental margin modeling system. One of these critical steps is incorporation of an updated, process-oriented shelf sedimentation algorithm within the larger SedFlux model. During Phases III of STRATAFORM, gravity-driven flows of fluid mud within the wave boundary layer were identified as the dominant mode of across-shelf transport of fine sediment during flood years. Thus the primary scientific objectives of our present project are to develop, validate and help implement within SedFlux a simple, computationally efficient formulation for shelf deposition which includes the fundamental physical processes associated with wave-driven gravity flows.
