Calgary Water Quality Model Development

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…

American Water Resources Association Presentation

Paul Craig, President of DSI, gave a presentation on Habitat Modeling at a dinner meeting for the Washington Section. Mr Craig demonstrated tools for supporting efforts to mitigate the impact of human development on fish habitat through enhancements to the physical habitat such as changes in substrate type and flow patterns. https://www.waawra.org/event-3018346

McClelland Lake Wetland Complex Study

DSI is supporting Suncor and Hatfield to develop an EFDC model that is integrated with a HydroGeoSphere ground water model of the McClelland Lake Wetland Complex in Alberta, Canada. The goal is to develop a surface water model to represent the transport and fate of WQ constituents along the fen and into the lake.
