Abstract:This report documents the research project “Support for Avalanche Sensing and Communications.” The primary goal of this research was the continued support of avalanche sensing and detection in a key Caltrans District 10 avalanche zone. The impending availability of this system will support avalanche start zone characterization and modeling, real-time avalanche detection and alerting, and optimal avalanche control operations. These capabilities will lead to safer winter roads with higher mobility and save the Department of Transportation money. The original avalanche-sensing system was developed under a previous research project. The current research continued support for this system; developed updates to the system design, hardware, and software; and prepared for the final installation of the system. Sensing regimes include snow depth across an avalanche start zone, camera imaging, temperature, and wind speed and direction. The District 10 site (chute 4 of Carson Spur on State Route 88) is fully prepared for instrumentation with the bench-tested prototype.
