| Zusammenfassung |
| Many works have shown that the relation between rock fall frequency and
volume is well fitted by a power law. Based on this relation, a new method
is presented which allows estimating the fall frequency and probability for
a wall section in a homogenous cliff, considering all possible rock fall
volumes. The hazard for an element located at the foot of the cliff, with a
minimal energy, is also estimated. The method has been applied to an
itinerary, for which the human risk has also been estimated. Rock fall
inventories featuring the location, date, and volume of the falls and the
dimensions of the fallen compartments (width, length, and thickness) are
needed for better estimating of hazard and risk. |
