Ask The Experts: Sediment Transport Modeling
For sediment transport modeling, EFDC requires a modeler to define particle size classes and specify the median diameter for each class, which can represent the average behavior of the particles.
Sediment Transport
Comparison of Different Turbulence Models on Sediment Transport
Sediment transport in open channel flows is influenced by turbulence, which governs the distribution of momentum and sediment throughout the water column.
Implementation of ULTIMATE-QUICKEST for Advective Transport in EFDC+
EEMS 12.5 introduces the ULTIMATE-QUICKEST scheme for advective transport in EFDC+, using quadratic interpolation to achieve third-order accuracy and reduce numerical diffusion while maintaining numerical stability.
Kingston Ferry Terminal Propwash Simulation
Sediment erosion caused by propeller wash from ships is of considerable concern in many ports and harbors for terminal safety.
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.
Propeller Wash Simulation Using Historical Ship Track Data
Simulation of the impacts of propeller wash in hydrodynamic and sediment transport models requires detailed information on ship travel routes and the physical characteristics of each ship.
Testing Procedures for the EFDC+ Propeller Wash Module with Sediment Transport
DSI is continually developing new features for EFDC+ and EFDC+ Explorer Modeling System (EEMS).
Using EEMS to Model the Effects of Sediment Dredging
Dredging refers to excavating sediments under a water body.
Wind-Wave Modeling with Sediment Transport in EFDC+
A preview of a DSI white paper comparing two approaches for simulating wind waves in EFDC+ — the internal SMB method and the external SWAN method — applied to the same wind-wave sediment-transport model of a sloped beach with offshore sandbars and rip channels.
