Abstract:

Ground movement was monitored using Interferometric Synthetic Aperture Radar (InSAR) coupled with on-site corner reflector technology for an area where the General's Highway in the Sequoia National Park, California crossed over an unstable slope. As part of proposed roadway improvements for this section, one corner reflector was placed on a known stable rock outcrop, and two corner reflectors were placed in known unstable locations on the slope above and below the roadway. This study found some minimal InSAR deformation at the corner reflector locations over a four month period of 1.7 to 2.5 mm vertical movement. and 2.3 to 3.4mm on the flow line.
