A Comprehensive Technology Assessment for Avalanche Hazard Management: Developing and Applying an Avalanche Hazard Technology Optimization Process to a Case Study on US Route 189-191 in Hoback Canyon, Wyoming

The primary value of this research will be the development of decision support metrics that will allow WYDOT and other state DOT transportation facility planners to make these decisions in a structured and near optimal way. To test the value of this research in a practical setting, the capabilities arising from this research will be utilized as transportation facility planning decision support in a case study to determine the optimal methodology and technology for the problematic Cow-of-the-Woods avalanche path on US Route 189-191 in Hoback Canyon, Wyoming. WYDOT and InterAlpine Associates will be utilizing the TAS O'BELLX Avalanche Initiating Blaster in this portion of the research project to test avalanche control at the Cow-of-the-Woods site. The assessment of the O'BELLX will be used as an active avalanche control. This is a constructive/passive avalanche defense that will be used to preclude the onset of avalanching and will allow WYDOT to take proactive actions to reduce the exposure of motorists to this evolving hazard. It is hoped that WYDOT will be able to bring down the offending avalanche while the roadway is temporarily closed, working from the premise that once it has avalanched, that the site is unlikely to avalanche again until the next severe storm.
