Welcome to the EE Modeling System

Create your EFDC model faster than ever

Everything you need in one convenient package.

Why Choose EEMS ?


EFDC_Explorer was designed with the end user in mind. With our graphical user interface you no longer need to deal with the tedious effort of determining which input files are needed and what their formats are. Also, EFDC_Explorer provides you a broad range of post processing tools to meet almost every model analysis and reporting need. This saves you time, sanity, and makes the modeling process run much smoother.


Our experts have been working with the Environmental Fluid Dynamics Code (EFDC) since its early development. We know that accuracy is critical for your projects. Our version of EFDC (EFDC+) has been significantly updated to provide more robust, accurate and stable model results. We are constantly testing for accuracy and identifying areas for greater performance.

Development Focus

We understood from the beginning that our tool needed to be constantly evolving to suit the needs of the modeling community. We have improved the original EFDC with faster processing speed, additional capabilities, computational improvements, and bug fixes over the course of the development process. We continue to improve and update the software with every release and user input helps us improve features and functionality.
