A rockfall protection embankment is an earthwork built in elevation with respect to the ground to intercept falling rock fragments before elements at risk such as roads and buildings are reached. This term is widely used in the rockfall community but the terms bunds and walls are sometimes used as alternatives.
The rockfall still takes place but an attempt is made to control the outcome. In contrast, active mitigation is carried out in the initiation zone and prevents the rockfall event from ever occurring. Some examples of these measures are rock bolting , slope retention systems, shotcrete , etc.
Talus cones produced by mass moving, north shore of Isfjord, Svalbard, Norway Mass wasting at Palo Duro Canyon, West Texas (2002) A rockfall in Grand Canyon National Park. Mass wasting, also known as mass movement, [1] is a general term for the movement of rock or soil down slopes under the force of gravity.
Protection forests are forests that mitigate or prevent the impact of a natural hazard, including a rockfall, avalanche, erosion, landslide, debris flow or flooding on people and their assets in mountainous areas. A protection forest generally covers the sloping area between a hazard potential (e.g. an unstable rock cliff or an avalanche ...
Rockfall simulators determine travel paths and trajectories of unstable blocks separated from a rock slope face. [36] Analytical solution method described by Hungr & Evans [37] assumes rock block as a point with mass and velocity moving on a ballistic trajectory with regard to potential contact with slope surface. Calculation requires two ...

Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards. [ a ] It is a widely accepted system promoted by numerous safety organizations.
