Baseline Rockfall Rates and Rockfall Protection in Virginia [PDF]
, 2010 Current approaches to rockfall hazard and risk mitigation have been dominated by a model in which rockfall is treated as a global slope stability phenomenon which is mainly triggered by precipitation, freeze-thaw, or root wedging. The methods implemented

From rockfall source area identification to susceptibility zonation: a proposed workflow tested on El Hierro (Canary Islands, Spain) [PDF]
Natural Hazards and Earth System SciencesRockfall modelling is a common topic in the landslide literature, but a comprehensive workflow for rockfall susceptibility zonation remains a challenge.

Counting scars on tree stems to assess rockfall hazards: A low effort approach, but how reliable? [PDF]
, 2013 Rockfall is a widespread and hazardous process in mountain environments, but data on past events are only rarely available. Growth-ring series from trees impacted by rockfall were successfully used in the past to overcome the lack of archival records ...

Numerical Simulation of Pipeline Deformation Caused by Rockfall Impact
The Scientific World Journal, 2014 Rockfall impact is one of the fatal hazards in pipeline transportation of oil and gas. The deformation of oil and gas pipeline caused by rockfall impact was investigated using the finite element method in this paper.

Hybrid barrier systems for rockfall protection
, 2008 This study examines hybrid barrier systems, incorporating field performance, limited rockrolling tests, and finite-element modeling. A hybrid barrier is a passive rockfall protection system consisting of a flexible fabric suspended from a top horizontal ...

Methods for predicting rockfall trajectories and runout zones
Rockfall hazard assessment without the use of rockfall trajectory and runout zone models is unthinkable in the 21st century. Such rockfall models have existed since the sixties, but nowadays an almost confusing palette of rockfall trajectory and runout ...
