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 CVLGrid.  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.

DSI Tools

In addition to EEMS, DSI has developed and maintains a range of other software tools used on specialized consultancy projects.  While these tools are not commercially available at this stage, DSI can provide them to clients as needed to support their ongoing project requirements.

W2_Tool Pre- & Post-Processor

W2_Tool is a pre- and post-processor for CE-QUAL-W2, comprising W2_Control, for model setup, and W2_Post, for model post-processing. CE-QUAL-W2, developed at Portland State University, models longitudinal-vertical hydrodynamics and WQ in stratified and non-stratified systems, and multiple algal, epiphyton/periphyton, zooplankton, macrophyte, CBOD, and generic WQ groups.

DTM_Tool

DTM_Tool was designed by DSI for creating and modifying digital terrain models (DTMs) and performing a range of analyses such as map digitization and bathymetric interpolization. It may used for generating model inputs for several hydrologic, hydraulic and hydrodynamic models including EFDC_Explorer, HEC-HMS and HEC-RAS. This software was developed by DSI and is customizable for project and client needs.
