Rockfall Mitigation: Project Life Cycle
This webinar focuses on the rockfall mitigation project life cycle for the flexible rockfall barriers installed above the Hell Hole Dam spillway. The webinar summarizes the project activities from the initial slope investigation utilizing SPRAT rope access techniques and in-field/computerized rockfall simulations to the selection, design, and construction of the flexible rockfall barrier system. The webinar includes an overview of the post-rockfall barrier damage and repairs, a summary of LiDAR change detection following the rockfall events, and back-analysis rockfall simulations used to estimate the energy absorbed by the 5-meter-tall 2,000 kJ barrier during the 2022 rockfall strike that was initiated during the 2022/2023 winter when California was hit with multiple atmospheric rivers that caused widespread damage due to flooding, landslides, and rockfalls.
