| Zusammenfassung |
| Risk assessments for natural hazards are becoming more widely used and
accepted. Using an extended definition of risk, it becomes obvious that
performant procedures for vulnerability assessments are vital for the success
of the risk concept. However, there are large gaps in knowledge about
vulnerability. To alleviate the situation, a conceptual extension of the
scope of existing and new models is suggested. The basis of the suggested
concept is a stadardization of the output of hazard assessments. This is
achieved by defining states of the target objects that depend on the impact
and at the same time affect the object's performance characteristics. The
possible state variables can be related to a limited set of impact
descriptors termed generic impact description interface. The concept suggests
that both hazard and vulnerability assessment models are developed according
to the specification of this interface, thus facilitating modularized risk
assessments. Potential problems related to the application of the concept
include acceptance issues and the lacking accuracy of transformation of
outputs of existing models. Potential applications and simple examples for
adapting existing models are briefly discussed. |
