Key outputs
What Rockyfor3D delivers
Design impact energy
Return-period based design impact energy at any defined location or structure.
Exceedance & intensity curves
Key data for exceedance-rate and intensity-frequency curves.
Spatial hazard maps
Spatial maps of reach probability, trajectory density and bounce height.
Impacts per source zone
Number of impacts per source zone — identifying which source areas drive risk.
Rockfall protection structures
Design parameters for protection structures and infrastructure
Rockyfor3D calculates and provides key data for the design of protection structures and infrastructure — such as the 100-year impact energy and jump heights on bridge piers, dam faces, rockfall nets or barriers.
Scales with your needs
From regional hazard mapping to site-specific design.
Applicable from regional hazard mapping to specific structural design and risk analysis.
