Coastal Landslide and Bluff Retreat Monitoring for Climate Change Adaptation and Targeted Risk Assessment

The goal of this research for Oregon Department of Transportation (ODOT) is to develop a more comprehensive data-driven framework for prioritizing coastal asset management. This is new research for ODOT, building upon recent smaller-scale, foundational efforts and recommendations. The objectives of this project are to: 1) Evaluate five representative sites reflecting a combination of coastal geologic terrains, landslide types, and coastal bluff erosion activities. 2) Determine current geotechnical and hydrological data, as well as landslide and bluff geometry and movement using traditional and advanced three dimensional (3D) technologies (LIDAR and real-time remote in-place Micro-Electro-Mechanical Systems (MEMS) sensors). 3) Quantify changes in landslide movement, groundwater change, and bluff erosion rates over an extended 7 year timeline to fully capture the episodic nature of sea cliff erosion in the context of climate change events. 4) Develop GIS/LiDAR based management framework for targeted risk assessment and climate change adaptation planning including guidelines for future evaluations of coastal infrastructure sites.
