We are excited to announce the release of our flagship software, EFDC_Explorer Modeling System (EEMS). EEMS10.3 provides a fully integrated propwash module that predicts bottom velocities, bed shear and sediment resuspension using ship information, position, and speed that dynamically couples to the three-dimensional hydrodynamics of the waterbody. It also boasts a vastly refactored and enhanced eutrophication module…
DSI is an engineering, planning, and research & development firm with its headquarters in the US. A Representative Office was established in Hanoi in 2002 to provide the international/national development agencies and international companies with focused and experienced technical and management support.
DSI has over 30 years of experience in providing water resources planning, flooding analysis and control, reservoir systems, groundwater flow, toxics transport, and water quality consulting services. DSI offers considerable expertise on a worldwide basis in water resources and environmental projects.
DSI develops and maintains the EE Modeling System (EEMS), a compete modeling package for hydrodynamics, sediment transport, toxics transport, and eutrophication. DSI also develops custom software for clients to solve specific engineering problems.
Real-time Modeling Systems
DSI has created real-time models for multiple clients to simulate hydrodynamics, temperature, and salinity. These models provide visualizations within 24-48 hours.

Due to our in-person training being postponted this year, DSI has developed a free and comprehensive online training program. This training is divided into different courses, numbered 100, 200, 300, with each level based on a user’s familiarity with EEMS. EEMS100 is now available and will introduce you to the basics of EFDC_Explorer software and help you…
HSPF is one of the most widely used software packages for modeling hydrology and water quality in watersheds. Dr. Anurag Mishra has provided BASINS and HSPF training to multiple clients, professionals, students in the past 12 years. He has now made this online training available free on the DSI website here.
DSI was at the Ocean Sciences Meeting from February 16th-21st 2020 in San Diego, California. This is the flagship conference for the ocean sciences and the larger ocean-connected community. DSI demonstrated our modeling tools, discussed your modeling problems, and provided advice and recommendations.
Matrix Solutions and DSI are partnering to develop the Bow River (City’s Reach) Water Quality Model Development using EFDC for the City of Calgary, Alberta, Canada. The EFDC model (2D-3D) will help to understand the temporal, spatial water quality and environmental risks with better resolution and will seamlessly integrate into AEP’s model of the Bow…
