Ground-based Interferometric Radar for Rockfall Hazard Monitoring

Rockfall events along transportation corridors are a major public safety hazard and can result in significant economic costs due to traffic delays and road repairs. Transportation agencies are in need of innovative technologies to help them deal effectively with rockfall hazards. Ground-based interferometric radar (GBIR) is an emerging remote-sensing technology that can be used to scan large structures or natural sites and detect sub-millimeter scale surface deformations. The work supported by this grant will supplement a larger research project funded by the Colorado Department of Transportation to study implementation and application of GBIR for rockfall hazard monitoring. The larger project will include: (1) full-scale monitoring of an active rockfall site in Glenwood Canyon, Colorado and (2) a controlled field study monitoring rock movements. The study supported by this grant will focus on quantifying the detection limits of GBIR for rock fall monitoring. A controlled field study will be performed where rocks of various sizes and located over a range of offset distances will be moved and measured. The GBIR will be used to scan the site and study the detection limits of the technology as well as the accuracy of the GBIR measurement.
