Component

The Colorado Rockfall Simulation Program (CRSP) was developed in 1987 to estimate the velocity, energy, and bounce heights of rockfall, which in turn forms a basis for selection of designs for mitigation. Several revisions were issued in the following years, and the program has been widely used for rockfall design. The new version of CRSP has been written based on a combination of Particle Flow Code and the Discrete Element Method for dynamic model simulation. This approach provides a more accurate approximation to the equations of motion for rock and slope interaction than employed by previous CRSP versions.
