What is EEMS?
The EFDC+ Explorer Modeling System (EEMS) includes EFDC+, EFDC+ Explorer (EE), and Grid+.
Why Choose EEMS?
EEMS is the software of choice for water resource modeling for many major environmental organizations in the U.S. and other countries, because of its efficiency, accuracy, and user-friendly features.
Efficiency
EE was designed with the end user in mind. Our GUI eliminates weeks to months of effort determining which input files are needed, file formatting and how to post process model results. EFDC+ allows the user to access the full computing power of multi-core systems, on site clusters or cloud based High Performance Computing (HPC) clusters to run simulations faster than ever. This saves resources and allows the modeler to pursue solutions with confidence.
Accuracy
Our experts have been working with the Environmental Fluid Dynamics Code (EFDC) since its early development and have experienced its problems first hand. We know that accuracy is critical for your projects, so our version of EFDC (EFDC+) has been significantly updated to provide robust, accurate and stable model results. We are constantly improving the capabilities of EEMS to respond to our community’s needs.
Development Focus
We understood from the beginning that our modeling tools must constantly evolve to suit the needs of the modeling community. Over the course of the development process, we have increased processing speeds, expanded capabilities, made computational improvements, and implemented bug fixes. With every release, we continue to improve and update features and functionality in response to user input.

Testimonials
I have found EFDC+ to be a really fantastic program. It has a really intuitive interface, a nice mesh builder, and great calibration analysis. I just started with EFDC+ in mid Sept and I already have a running draft model of hydrodynamics, salinity, and temp for a pretty complex system; I've made huge progress in just the last 3 weeks.
Thank you for creating this software. It is definitely worth the investment.

This past year has been very meaningful to me as well as I started using EFDC+. It has saved me tremendous amount of modeling effort, and I’m very excited and grateful to learn that DSI is planning to make it open source and available to the public. I really look forward to continuing collaboration with DSI on the EFDC development in this coming year.

If it wasn't for DSI, I'd still be editing text files and
trying to figure out how to plot data.
