LIDAR & SASW technologies for geotechnical earthquake engineering LIDAR & SASW technologies for geotechnical earthquake engineering
Geotechnical engineering methods are validated through comparison of field‐data of surface deformations and sub‐surface state properties. Recent advances in non‐invasive surface imaging and sub‐surface stiffness characterization allow us to rapidly and inexpensively map these spatial and physical properties in two and three dimensions. In this paper, we discuss new technologies used at...

The internal structure of sand bars on the Colorado River, Grand Canyon, as determined by ground-penetrating radar The internal structure of sand bars on the Colorado River, Grand Canyon, as determined by ground-penetrating radar
High-resolution, subsurface imagery from ground-penetrating radar (GPR) has revealed the internal structure of sand bars at seven sites on the Colorado River, Grand Canyon. Based on reconnaissance-level surveys, we recognized three stratigraphic units and several intervening unconformities. Unit A, which exhibits hyperbolic reflections and always occurs at the base of the section, is...
