Accounting for climate change impacts in the design of resource road stream crossings
Designers and regulators are increasingly rationalizing for climate change in stream crossing designs. While the baseline practice in forestry is “add 20% to the design flood”—which originates from a 2012 Engineers and Geoscientists British Columbia Guidance publication—professionals are now starting to use publicly available climate tools that give more localized estimates. These tools often produce answers different from each other and from the 20% guidance. Ultimately, the expert judgement of designers defines how any of these options are integrated into the larger design flood hydrology design process.
What is the webinar series about?
In February of 2020, FPInnovations organized three webinars that outlined the approaches available to designers when rationalizing for climate change at a typical crossing (recordings). Presentations showed how to use several publicly available interactive map tools for British Columbia (B.C.) as part of crossings design, and highlighted tool limitations. In this follow-up series, attendees will learn about developments in tools, data portals, and how professionals are integrating climate change into design flood hydrology through case studies.
Who should participate?
This free webinar series is open to all. It is designed for professionals involved in the design and management of resource road infrastructure working in B.C. However, the issues and approaches to solutions that will be covered are also relevant to professionals across Canada.
June 18 (Thursday)
Updates and Developments in Climate Change Tools for B.C. + Case Study from the Southern Interior
- Orientation: updates on topics from first series (Matt Kurowski EIT, FPInnovations)
- A first look: the new Plan2Adapt tool (Kari Tyler, Pacific Climate Impacts Consortium)
- Review: use of two tools that were not included in the first series (Columbia Basin Climate Source and climatedata.ca), a prototype tool that calculates risk probabilities of climate indices, as well as a case study crossing in Southeast B.C. that applies these tools (Mel Reasoner, Climate Resources Consulting)
June 23 (Tuesday)
Case studies from the Coast and Northern B.C.
Crossing case studies in Coastal and Northern B.C. ranging in drainage size: how data and methods used in design flood hydrology relate to uncertainties of climate projections from various tools, and how climate projections can inform design (Lee Deslauriers P.Eng., RPF, StoneCroft Engineering and Paul Mysak P.Eng., Onsite Engineering Ltd.)
June 25 (Thursday)
From Snowmelt to Streamflow: Data Portals for Future Hydrologic Conditions + Discussion: Climate Change Tools Needs for Crossings Design
- Introduction: a data portal from the Pacific Climate Impacts Consortium that provides streamflow for a range of future climate conditions in sub-basins of the Peace, Fraser and Columbia (Arelia Schoeneberg, Pacific Climate Impacts Consortium)
- Facilitated conversation with designers: applied use of climate tools (Kari Tyler, Pacific Climate Impacts Consortium)
