Recent studies have demonstrated the applicability and potential for ground-based lidar mapping to support avalanche control operations. High-resolution maps of snow depth and snow depth change derived from repeat lidar surface elevation surveys reveal detailed patterns of accumulation, scour, and loading due to the complex precipitation and redistribution processes in mountain environments. The ability to map starting zone depth patterns from a safe distance provides a unique capability to assess loading patterns, plan mitigation strategies, and evaluate the effectiveness of control efforts.
Deems will present results from two ongoing projects in collaboration with Arapahoe Basin Ski Area and the Colorado Department of Transportation. Applications of the lidar-derived snow depth data products include targeting of explosive rounds, planning of explosives delivery tramway locations, and evaluation of results from Gazex application.
