A Review of EFDC Versions
Over the years, multiple versions of EFDC developed and supported by different organizations have come become available. This post reviews some of these versions and provides the key differences among them.

BACK Lake Washington Real-Time Model DSI recently developed a real-time model for Lake Washington, along with a public-access model portal. The portal allows users to view historical and current data on measured and simulated water levels, temperature, and velocity, presented in map view, time series, and vertical profiles. Users can also compare the data with…
BACK 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. JSON serves as a syntax for serializing objects, arrays, numbers, strings, booleans, and null. Although it is based upon JavaScript syntax, it…
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…
