Unmanned Aircraft System Assessment of Landslide Safety for Transportation Corridors
An assessment of unmanned aircraft systems (UAS) concluded that current, off-the-shelf UAS aircraft and cameras can be effective for creating the digital surface models used to evaluate rock-slope stability and landslide risk along transportation corridors. The imagery collected with UAS can be processed using a photogrammetry ...
A Platform for Proactive Risk-Based Slope Asset Management - Phase I
Unstable slopes, including landslides, rock falls, and debris flows, present significant risk to safety and regional commerce, and present a chronic concern for highway managers. Due to the widespread spatial and temporal distribution of these hazards, most states, have, or are taking, measures to manage slopes along their ...
A Platform for Proactive Risk-Based Slope Asset Management - Phase II
The lidar visualization technique developed by this project enables highway managers to understand changes in slope characteristics along highways. This change detection and analysis can be the basis of informed decisions for slope inspection and remediation. Mitigating unstable slopes and their associated hazards reduce ...
Transportation Corridor Resiliency in the Face of a Changing Climate
The effects of a changing climate on transportation corridor slopes are poorly understood, but several recent studies have suggested that landslide activity, especially rockfall, is likely to increase as a consequence of the increased occurrence of intense precipitation events. Effects from climate change such as extreme ...
