Using 2-D modeling to inform a design plan for river safety
After the 2013 flood in Calgary, the City identified a potential flood and erosion risk in the Bow River—revegetation of a gravel bar and changes in the river channel posed a risk to the community. The City enlisted us to address public safety, flood, and erosion risks present for a three kilometre reach, or stretch, of the river.
We conducted 2-D modeling to analyze existing conditions and potential future channel changes at the site. Following our modeling and analysis we collaborated with stakeholders and conducted a workshop to get feedback on proposed design concepts. After evaluating all design options, we worked with the City to proceed with a design plan best suited for community safety. Experienced engineers, biologists, regulatory specialists, and landscape architects secured regulatory approvals and developed the plan to remove historic concrete and rebar debris that posed a public safety hazard on an island in the river.
Our team managed the construction, provided environmental monitoring support, and construction quality assurance for the successful removal of over 160 tonnes of concrete and steel from the island and river channel. Completed in 2021, this project helped make the Bow River safer for boaters, rafters, and other river users.
