Objectif(s): To determine the role of forest fire, climate fluctuations and river dynamics in controlling slope stability in glacial sediments and shales of the Mackenzie Valley; to determine the age of landslides using dendrochronology or radiocarbon dating; to determine if climate warming is likely to influence slope stability.
Description du projet: In this ongoing study, the frequency and characteristics of landslides occurring in the Mackenzie Valley area are examined. I am trying to determine the roles that forest fires, climate changes and water flow in rivers play in the location and number of landslides. The field work will involve taking measurements on past landslides that include measuring permafrost features and taking core samples from trees (to provide an estimate of the date of the landslide).
