| Abstract | In the last three decades, hundreds of landslides, often affecting areas several hectares in size, have been identified and mapped in the Mackenzie Valley. This paper will present the Natural Resources
Canada's Mackenzie Valley Project component focusing on regional landslide mapping along the proposed gas pipeline route, between Inuvik (68.35°N, 133.72°W) and Norman Wells (65.28°N, 126.83°W). In this paper, a parametric approach was applied to the
Travaillant-Thunder pilot site to estimate the terrain susceptibility to landslides. The Travaillant-Thunder pilot site was selected as it offers a wide variety of terrains in terms of permafrost conditions, surficial geology, relief, vegetation, and
is known for widespread landsliding where typical landslide types were observed. A preliminary landslide susceptibility map was created for the Travaillant-Thunder Pilot Site using a parametric method where six layers were input in the model:
surficial geology, permafrost type, permafrost ice content, slope angle, slope aspect, and land cover. The susceptibility map is an important planning tool for communities, private companies and public departments when new infrastructures are built
in permafrost terrains. |
