Stream Channel Assessment,
Processes & Restoration
Our experienced geomorphologists and technical staff bring unparalleled expertise in the assessment, restoration, and management of rivers and streams. Collaborating across disciplines, Matrix provides integrated solutions from local site to watershed scale drainage networks situated in rural and urban land uses and in a range of surficial geology settings.
We routinely lead characterization of stream morphology to:
- Assess fluvial erosion hazards
- Develop alternatives for erosion control in environmental assessments
- Develop management strategies as part of land use planning (subwatershed, secondary, tertiary plans and site plans)
- Assist in culvert/bridge design
- Define erosion thresholds to inform stormwater management
Stream Channel Assessment, Processes & Restoration
Key service areas include:
- Watershed and subwatershed drainage network characterization
- Reach assessments, erosion and asset condition inventory mapping and GIS database development
- Geohazards and erosion hazard delineation
- Meander belt and stable top of slope assessments
- Headwater drainage feature assessments
- Channel modifications and realignment, erosion mitigation, bank/slope stabilization and infrastructure protection
- Natural channel design, aquatic habitat enhancement, and floodplain restoration
- Erosion threshold and scour analyses for stormwater management and infrastructure crossings
- Crossing assessments for linear infrastructure
- Capital works planning
- Construction supervision, technical construction support, and contract administration
- Protocol Development
- Regulatory agency permitting
- Post-construction monitoring

Drumquin Park Weir Removal and Channel Enhancements
In collaboration with Enbridge and the Town of Milton, Conservation Halton undertook a priority environmental project to decommission the existing Drumquin Park weir on East Sixteen Mile Creek and restore the natural channel function and habitat. Sixteen Mile Creek provides aquatic habitat to many species including the Silver Shiner, a species classified as at risk in Canada and threatened provincially. Removal of the Drumquin weir provides the opportunity to restore connectivity to downstream occupied Silver Shiner habitat and rehabilitate degraded Silver Shiner habitat – actions that address the various recovery objectives for this threatened species.
City of Calgary 12 St. S.E. Bridge Replacement
The City of Calgary recently embarked on a project to replace the 109-year-old 12 Street S.E. Bridge over the Bow River, the main access point between the Calgary Zoo and locations to the south. The bridge was in poor condition and deteriorating beyond a safe, useable condition.
AltaLink Oldman River Bank Protection
The foundations of four AltaLink transmission structures were threatened due to significant bank erosion along a 900m reach of the Oldman River, Alberta. Further bank erosion could impact the reliability of the line or require the relocation of the structures to another location.
