At each impact, the slope angle is randomly varied from the nominal value input by the user within the limit set by the maximum probable variation in the slope. Spherical, cylindrical and disk shaped rocks can be simulated. The model takes into account, slope profile, rebound and friction characteristics of the slope, and spinning energy of the rocks. 'This rockfall computer program, which simulates rocks tumbling down a slope, predicts the statistical distribution of speed and bounce height, and can be used for locating and designing rockfall mitigation.

It seems the Colorado Rockfall Simulation Program. Which are the best open/free softwares for debris flow and. The Colorado Rockfall Simulation Program (CRSP) was developed to model rockfall behavior and provide a statistical analysis of probable rockfall events at any given site. This Colorado Rockfall Simulation Program revision. All recovered files should be validated for the integrity of the recovered data.Ħ Colorado Rockfall Simulation Program, Version 4.
Support for the ZFS file system and RAID-Z (single and double parity).E-mail Message: I thought you might be interested in this item at Title: Colorado rockfall simulation program: version 3.0 user's manual Author: Timothy J Pfeiffer Jerry D Higgins Richard D Andrew Robert K Barrett Robert B Beck Colorado. The results confirmed common assumptions on ideal properties of a protective forest stand against rockfalls.The E-mail message field is required. For the profile discussed in this paper, the largest effect upon falling 3 m 3 blocks was obtained with a high forest containing 350 trees per ha. Furthermore, a completely forested slope reduces velocity and energy of the falling blocks much better than a sparsely forested slope.
Results showed that the actual rockfall event can be well simulated. Rockfalls into different forest scenarios were also modelled for the site. An actual rockfall trajectory was measured, recorded, analysed and simulated with a rockfall model. Therefore, in this study the question was assessed of how mountainous forests may influence rockfalls of single boulders. Although the general protective effect of forests against rockfalls is currently not questioned, little is known about the ideal properties of a forest stand that provides good protection. Rockfalls are a major threat to settlements and transportation routes in many places.
