From Salinity Modeling to Habitat Decisions with EEMS
A case study on the Lower St. Johns River Estuary demonstrating how EFDC+ and EEMS can model long-term salinity intrusion and translate modeled salinity patterns into actionable habitat indicators.
Modeling Sediment Resuspension in a Coastal Environment Due to Ship Traffic
Sediment resuspension occurs in harbors across the world as a function of propeller-induced water velocities, and resulting shear stress, at the sediment-water interface.
