EFDC+ Explorer Modeling System (EEMS)

EEMS is DSI’s flagship software, a complete modeling package for hydrodynamics, sediment transport, toxics transport, and eutrophication. This state-of-the-art suite comprises EFDC+, EFDC+ Explorer (EE), and Grid+. Watch the video below or select the links to the EEMS website to learn more.


EFDC+ Explorer

A Graphical User Interface (GUI) that provides a broad range of pre-processing and post-processing tools to assist in developing, calibrating, and analyzing EFDC+ models.



A state-of-the-art, open-source, multifunctional surface water modeling engine that includes hydrodynamic, sediment-contaminant, and eutrophication components designed to simulate aquatic systems in one, two, and three dimensions.



A grid-generating tool for hydrodynamic models that makes the process of building complex 2-dimensional curvilinear orthogonal grids quick, intuitive, and robust enough for even the most challenging waterbodies.
