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.
Unlimited Phytoplankton and Zooplankton Modeling in EEMS
EFDC+ eutrophication model has been refactored and enhanced with the definition of a general phytoplankton group.
Comparative Study of Different Turbulence Closures in Modeling Lake Mendota’s Thermal Behavior
Lake Mendota, the largest lake in Madison, Wisconsin, exhibits complex thermal dynamics with pronounced summer stratification and reverse winter stratification under ice cover.
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.
Coupling HSPF Water Quality Model with EFDC+
Developing a hydrodynamic or a water quality model may require input of boundary conditions from other models.
EEMS10.4 to WASP8 Linkage
The Water Quality Analysis Simulation Program (WASP) is a dynamic, spatially-resolved
EEMS Feature: Partial Flow Blocking
Partial flow blocking was added as a feature of EEMS with version 10.1.
EFDC+/GOTM Scenarios: Free Convection
This blog discusses the results of a free convection test case performed with different turbulence closures available in EEMS 12.
EFDC+ GOTM Scenarios: Open Channel Flow
The choice of turbulence closure scheme has important consequences on model results through mixing and circulation (Burchard et al., 1998)
EFDC+ MPI Multi-core Scaling Study
In 2020, DSI implemented MPI in EFDC+ to improve model run time.
EFDC+ with Hydrologic Simulation Program-Fortran (HSPF)
Developing a hydrodynamic or a water quality model often requires boundary conditions from other sources
Enhanced Jet and Plume Features Coming to EEMS
Simulation of jets and plumes is an essential aspect of computational fluid dynamics. Jet and plume modeling is required in many natural and industrial applications
Estimating Ship Engine Power for EFDC+ Propeller Wash Simulations
Developing a propeller wash model requires specifying the ship and propeller properties as model input parameters.
