Description

This report provides comprehensive documentation of landslide, permafrost subsidence and fluvial erosion-related geohazards for the Yukon portion of the Dempster Highway. It provides Yukon Department of Highways and Public Works – Transportation Engineering Branch a practical geohazard inventory that will help guide planning and mitigate future risk to the highway. It also becomes a valuable reference pertaining to slope stability, permafrost and fluvial processes in northern Yukon. Results from this study identified 54 mass movement geohazards and 102 meander-highway encroachment sites with the potential for future highway impact. Of particular significance, 75% of the mapped mass movement geohazards are influenced by permafrost or degrading permafrost, an important geological attribute considering future temperatures are expected to increase.
