4.8. Conclusion
Boulders fall as a result of the failure mechanisms of rocky cliffs and bring
dynamic phenomena into play that can be described in a simplified way by applying
the principles of general mechanics and the mechanics of geomaterials.
It is necessary to turn to numerical models to simulate the behavior of real sites
in two or three dimensions (see Figure 4.13).
Currently these models show a relatively high performance, particularly when it
is possible to calibrate them with on-site observations from previous events that
have left traces and damage, which must be surveyed in detail.
