Colloquium Lecture Tour

Established in 1977, the Colloquium Lecture is an annual commissioned presentation and paper. It is targeted to a younger member of the CGS, typically 40 years of age at the time of the nomination, to provide information of particular interest to the geotechnical community on topics of importance to the Canadian geotechnical field. Its purpose is to encourage and provide an opportunity for a younger member of the CGS to pursue studies required for its preparation. It is presented at the annual Canadian Geotechnical Conference.

Since 2016, the Colloquium Speaker has also been offered the opportunity to present their Colloquium Lecture at various locations across Canada through the Colloquium Lecture Series.  It is preferred that the lectures be presented in a University setting with effort devoted to encouraging participation of undergraduate and graduate students.

The Cross Canada Lecture Tour Speaker is:

Dr. Ryley Beddoe, Royal Military College of Canada

Dr. Ryley Beddoe is an Associate Professor in the department of Civil Engineering at the Royal Military College of Canada (RMC). She received her B.Sc. and B.Ed., as well as her M.Sc. and Ph.D. in civil engineering at Queen’s University. Dr. Beddoe is a Research Director in the GeoEngineering Centre at RMC-Queen’s. She is also a co-investigator with PermaRail and PermafrostNET. Her research program focused on understanding the overarching impact on geotechnical design driven by climate change in Canada’s Arctic. Current and recent research includes investigating how permafrost geohazard impacts infrastructure in the Arctic, monitoring thaw instabilities along the Hudson Bay Railway in Northern Manitoba, and ice road investigations and portage resilience in the Northwest Territories. Her research is supported by Transport Canada, the Natural Sciences and Engineering Research Council of Canada, Government of Northwest Territories, Associate Engineering/NOR-EX Ice Engineering, National Research Council Canada, and the Department of National Defence

Topics:

Meeting the challenge of geotechnical transportation infrastructure on degrading permafrost

Abstract:

As permafrost in the Canadian Arctic undergoes climate driven degradation and changes, the stress and impact it will have on current and future linear infrastructure networks will be significant. Now more than ever, it is critical to work towards an understanding of not only why but also how. How will we learn from today to plan and design adaptation and mitigation techniques for resilient infrastructure in the future? How can we develop models that will allow us to ‘dig deeper’ in our understanding? In her current research in this field, Dr. Riley Beddoe is exploring questions like these, including: How can numerical modelling techniques allow us to predict future infrastructure risk? What adaptation techniques will limit the impact of permafrost degradation for infrastructure networks? How do these techniques change if the network is a railway? An ice road? A highway? In this presentation, Dr. Beddoe will present her and her team’s most recent research results aimed at answering these, and other related arctic geotechnical engineering questions.
