Quantifying Avalanche Risk

With any kind of transportation corridor, it is possible to quantify the avalanche risk objectively using the Avalanche Hazard Index.

With any kind of transportation corridor, it is possible to quantify the avalanche risk objectively using the Avalanche Hazard Index (AHI) (Schaerer, 1989). Our firm has updated this complicated risk model to include operational templates that allow risk-reduction scenarios to be easily accomplished with risk/benefit comparisons. Outputs can also compare risk reduction measures undertaken in alignment with other nationally recognized avalanche programs.

Examples:

DHA has completed this analysis for several national railroads in Canada and the United States, including the Department of Transportation in Colorado, Montana, Alaska, and the Milford Road in New Zealand.

Avalanche Risk Reduction Programs

Avalanche Research

DHA and its predecessors (Alcan Avalanche Services) have been involved in avalanche research since 1982. (Read more)

Short Term Risk Reduction

Risk Reduction for projects brief in time or scope, but where some level of avalanche risk exists. (Read more)

Longer Term Risk Reduction

Risk Reduction for projects where avalanche risk is primary and an avalanche safety plan is developed. (Read more)

Concept Planning

Planning for large multi-phased projects with the project's viability not determined until a future date. (Read more)

Ski Area-Based Avalanche Assessments

DHA is at the forefront of producing concept and implementation plans for conversion from military artillery to Remote Avalanche Control Systems (RACS). (Read more)

Urban Risk Reduction

Recent trends highlight the difficulty of implementing avalanche zoning laws on the interface between wild and urban settings. (Read more)

Project Management

Providing support in many forms for your capital construction efforts related to implementing an avalanche program or modifying an existing program. (Read more)
