Presentation Abstract:         

Light detection and ranging technology, or lidar, is a promising tool for assessing unstable ground due to its resolution, accuracy, and the ability to process away visual obstacles, such as vegetation. In particular, laser scanning has significant utility when applied repeatedly over time, quantifying changes in terrain that may not be easily discernable to the eye. This presentation will touch on some ongoing research that employs lidar for (1) regional landslide inventorying and landslide susceptibility, and (2) quantifying coastal retreat and its influence on landslide movements. A semi-automated approach that uses lidar to recognize geomorphic features and supplement manual landslide inventorying is presented. Thereafter, an approach that uses landslide inventories to leverage region-specific, shallow landslide susceptibility is considered. An ongoing collection of lidar along the Oregon Coastline is used to better capture coastal erosion and its influence on slope instability. The increasing availability of lidar presents us with a unique opportunity to better assess the risk stemming from geohazards, enhance asset management, and understand geomorphic and geologic processes at a more refined level.

Speaker Bio:

Ben Leshchinsky is an associate professor in geotechnical engineering at Oregon State University. The primary focus of Bens research is on basic and applied geomechanics, soil reinforcement, slope stability, and in recent years, use of remote sensing technologies applied towards assessment of natural hazards. Ben received his BS from the University of Delaware in 2007, and his MS and PhD from Columbia University in 2008 and 2012, respectively. Ben is a registered professional engineer in Oregon, an editorial board member of both the ASCE Journal of Geotechnical and Geoenvironmental Engineering and Geotextiles and Geomembranes. He is the recipient of 2018 International Geosynthetics Society Young Member Achievement Award, the 2016 International Landslide Symposium Young Paper Award, among other awards for research and teaching.
