Implementation of Domain Decomposition in EFDC+ Using MPI
A primary function of EFDC+ is to solve the governing Partial Differential Equations (PDEs) for fluid flow and constituent transport.
New Features
Implementation of GOTM in EFDC+
Since the early development of Environmental Fluid Dynamics Code (EFDC)
Implementation of Macrophyte Effects on Hydrodynamics in EFDC+
Submerged macrophytes are part of an essential relationship between the physical habitat and the biological community.
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.
Incorporation of COARE 3.6 into EFDC+
The Coupled Ocean-Atmosphere Response Experiment (COARE) bulk algorithm, developed by C. Fairall, E. F. Bradley, and D. Rogers
JSON Formatted Files in EEMS
JSON (JavaScript Object Notation) is an increasingly common standard data format to store and transmit data objects that use text designed to be easily read by humans.
Modeling Ice Formation in EEMS: Part 1 – Introduction to the Heat-Coupled Ice Model
Accurately simulating seasonal ice cover is crucial for understanding the hydrodynamics, primary production, and water quality of lake systems.
Modeling Ice Formation in EEMS: Part 2 – Introduction to the Heat-Coupled Ice Model
Our previous blog introduced the heat-coupled ice model implemented in EEMS. We also demonstrated its capabilities through a simulation of ice formation and melting in Lake Mendota
Navigation Lock Feature in EEMS
A lock is a hydraulic structure employed to facilitate the movement of boats, ships, and similar watercraft between different water levels on rivers and canals.
New EEMS Feature Timely For Hurricane Season- 4 Weeks Until Release
EEMS10 now has the ability to simulate spatially and temporally varying fields, such as a wind or barometric pressure fields.
New Vertical Layering Options in EEMS 12.1
A new vertical layering option following the Sigma-Zed (SGZ) approach has recently been added to EEMS. The new SGZ scheme offers significant flexibility in configuring the vertical layering system
Partial Depth Flow Blocking - Part 1
DSI has added a new capability to EFDC+ 10.1. This new capability allows the model to simulate partially blocked depths due to floating objects
Partial Depth Flow Blocking - Part 2
Lake Washington is a very deep lake that made conventional bridge construction difficult. To allow a traffic to cross the lake, a floating bridge was constructed.
Performance of COARE 3.6 for Surface Heat Exchange in EFDC+
Following the implementation of COARE 3.6 in the EFDC+ code, a new option for calculating water surface heat exchange has been added.
Shellfish Farm Module in EEMS10.2
The new shellfish sub-model in EEMS10.2 was used to replicate the Kobayashi et al., (1997) test case
