CRSP-3D Application for Remediating a Rockfall at Yosemite National Park

A novel rockfall simulation program, CRSP-3D, successfully replicated a 2012 rockfall event at Yosemite National Park involving a 500-ton granite boulder, demonstrating its potential for accurate hazard mitigation. By leveraging discrete element modeling and field data, the program calibrated critical parameters such as slope material properties, rock size, and geological conditions to simulate complex rockfall dynamics—including bouncing, sliding, rolling, and launching. This case study highlights CRSP-3D's ability to provide reliable data for designing remediation strategies, including barriers and catchment areas, addressing a longstanding challenge in numerical modeling validation.
