Configuring Vertical Profiles
Following the implementation of COARE 3.6 in the EFDC+ code, a new option for calculating water surface heat exchange has been added.
Water Quality
Coupling HSPF Water Quality Model with EFDC+
Developing a hydrodynamic or a water quality model may require input of boundary conditions from other models.
EFDC+ with Hydrologic Simulation Program-Fortran (HSPF)
Developing a hydrodynamic or a water quality model often requires boundary conditions from other sources
Enhancements to the EEMS GUI
As we added new features to EFDC+, our Graphical User Interface (GUI), EFDC+ Explorer (EE) has also changed to support these new features and capabilities.
Impact of Elevation on DO Saturation
A commonly recognized phenomenon is that as the altitude increases, the atmospheric pressure decreases.
Integrating Multi-Source Spatial and Temporal Data for the Calibration and Sensitivity Analysis of a Water Quality Model in Lake Mendota
DSI developed a three-dimensional water quality model using EEMS to generate predictions of eutrophic characteristics, including dissolved oxygen levels, algal concentrations, and nutrient rates.
Lake Washington Real-Time Model
DSI recently developed a real-time model for Lake Washington, along with a public-access model portal.
Magnuson Park Closed for High E. Coli Levels
Beaches and parks along Lake Washington provide a great environment for outdoor activities and relaxation for residents nearby.
Major Changes in Eutrophication Module from EFDC+10.3 to EFDC+10.4
In EFDC+, the eutrophication module refers to modeling aquatic plants and algae, zooplankton, and the biochemical transformation of nutrients during this process.
Mass Balance Calculation for Waterbodies using EEMS
A waterbody typically has multiple tributaries contributing flow and other constituents to the domain.
Simulating Desalination Intakes and Brine Discharge in EFDC+
EFDC+'s withdrawal/return boundary condition now supports signed discharge modifiers and per-constituent offsets, so you can represent consumptive intake, brine discharge, and dilution with the discharge concentration derived from mass conservation instead of a prescribed value.
