This presentation will focus on the applications of empirical methods to estimate potential landslide runout. It will review new compilations of Canadian and international case studies for various landslide types.

Estimating the potential runout distance of a landslide and its associated impacted area is an important component of landslide hazard and risk analysis. This presentation will focus on the applications of empirical methods to estimate potential landslide runout. It will review new compilations of Canadian and international case studies for various landslide types. It will also discuss how the application linear regressions and survival functions to a dataset of 49 Canadian rock avalanches with multiple geological, topographic, and runout path attributes has allowed us to characterize their importance on the observed runout distance.

This presentation will also introduce a classification of mass flows (e.g., debris flows and splash zones) associated with rock avalanches based on a compilation of 32 rock avalanches and 23 rock avalanche-generated sediment mass flows from around the world. It presents a decision tree framework to estimate the extent of potential rock avalanches and rock avalanche-generated sediment mass flows for hazard and risk analysis. The application of these empirical-statistical techniques for other hazard types, including mine pit runout, tailings flows, and natural debris flows will also be introduced. The techniques presented are developed to give practitioners simple tools they can use for screening level assessments of hazards.

Speakers

Dr. Marc-André Brideau, P.Geo.

Marc-André is a senior engineering geologist at BGC Engineering Inc. He specialises in rock slope hazard assessment, geohazard risk assessment, terrain stability mapping, slope stability modelling, landslide runout modelling, and aerial photograph interpretation. Marc-André is also an adjunct professor in the Earth Science Department at Simon Fraser University.

Andrew Mitchell, P.Eng., M.A.Sc.

Andrew is a geotechnical engineer at BGC Engineering. He specialises in landslide runout estimation, slope hazard assessment, slope stability modelling, and the application of remote sensing for hazard assessment and monitoring. Andrew is also completing his PhD in the Earth, Atmospheric, and Ocean Science Department at the University of British Columbia.
