How differences between snow avalanches and other slope hazards affect mapping and mitigation

A presentation video for GeoVirtual in September 2020. Bruce Jamieson, Dave Gauthier and Chris Wilbur.

Abstract: Snow avalanches differ from other slope hazards such as debris flows and landslides in ways that affect mapping and mitigation. Snow avalanches start as a result of failure in a bonded granular material in which the bonds are close to the melting point. Periods of instability are often limited to hours or days. In contrast to other slope hazards, explosives are effective triggers of unstable snow, thereby shortening periods of instability and allowing parts of ski areas or transportation corridors to be quickly re-opened. Where snow avalanche occurrences observations are available for a decade or more, this often results in better occurrence and runout records than for other slope hazards. For snow avalanches, hazard mapping thresholds based on a low annual probability (e.g. Pa ≤ 10^-3) are especially uncertain and problematic for hazard mapping. CC BY-ND

A successful avalanche operation starts with good planning. This 9-minute video highlights some aspects of avalanche planning for those who work in avalanche operations. On many planning projects, the planning team includes practitioners with operational experience. Bruce Jamieson, 2020, CC BY-ND.

How do snow avalanches differ from other slope hazards?

By understanding the differences between snow avalanches and other slope hazards, the authors of Planning Methods for Assessing and Mitigating Snow Avalanche Risk hopefully made it accessible to specialists who plan for other slope hazards. Bruce Jamieson, 2019, CC BY-ND.

ISO 31000 and avalanche mitigation projects

This presentation is similar to a paper presented at the 2013 ISSW in Grenoble, France.

Quantitative risk analysis for a structure in an avalanche path

This video presents a simplified quantitative risk analysis for an object of value that is fixed in a snow avalanche path. The concepts can be adapted moving objects such as vehicles or people and for other mass movements.

Has the snow climate changed in western Canadian mountains?

Climate change has been a focus for the avalanche world over the last few years. The Asarc group at the University of Calgary recently contributed two papers to the discussion, which we have summarised in this video. 2015,, CC BY-ND.
