BACK 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. In this post, we describe three major changes in the GUI. Water Quality Interface With EFDC+’s new ability to simulate unlimited algal, macrophyte, periphyton, and…
BACK Modeling Interaction Between Phytoplankton and Zooplankton in EEMS Introduction Zooplankton population modeling is a significant new feature in the recently released version of EFDC_Explorer Modeling System (EEMS 10.3). Built as a sub-module of the Water Quality module, the new zooplankton feature is a first step toward modeling the effects of eutrophication on higher-level predators.…
There can be multiple reasons when a modeler needs to incorporate results from another model. It can be the lack of direct measurement of specific properties or…
This post introduces a simple testing process to demonstrate how the propeller wash module works with EFDC+’s sediment transport process modeling features.
The Network Common Data Form (NetCDF) data format was originally intended to create, access, and share array-oriented data in a form that is self-describing and portable…
Communicating your modeling results to a wide variety of audience is as important as developing a good model. Animating the processes is one of the most powerful ways in which a modeler…
Wind-induced waves affect the propagation of gravity waves. Wave modeling hindcast is a critical step for wave energy development and…
Water quality simulation in waterbodies involves the biochemical transformation of the nutrients, their movement through several water layers….
In this post, we would like to demonstrate how the propeller transfers the energy to the water column causing sediment resuspension.
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.
Many urban waterfronts are contaminated with metals, petroleum hydrocarbons, and other organic chemicals. The contamination could be as much as 20 feet…
Climate change is an accepted reality, so most infrastructure development and maintenance will require the evaluation of possible impacts of climate change.
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. While such events occur with….
The warm waters and shallow, vegetated waterways of the Gulf of Mexico provide valuable habitat to a diverse range of plants and animals….
As part of DSI’s committment to the scientific and modeling community, DSI is now providing a template script that modelers can use to run an HSPF model, process the output, run the EFDC+ model, and plot the output.
With so many new computer languages available today, a question often asked is, “Why is EFDC+ coded in Fortran language?”
EFDC+ support input of spatially and temporally varying boundary conditions as field files, which means user can assign…
Following the release of EEMS10.2, the DSI Team is busy developing exciting new features for the next version of EEMS….
Join Mr. Paul Craig, the chief developer of EFDC+ and EEMS to learn how domain decomposition and MPI can help speed up your EFDC+ model.
EEMS from version 10.2 onwards will include a Shellfish Farm Module. This module incorporates a modeling approach….
