| Summary: | Early warning systems (EWSs) are increasingly applied as preventive measures
within an integrated risk management approach for natural hazards. At
present, common standards and detailed guidelines for the evaluation of
their effectiveness are lacking. To support decision-makers in the
identification of optimal risk mitigation measures, a three-step framework
approach for the evaluation of EWSs is presented. The effectiveness is
calculated in function of the technical and the inherent reliability of the
EWS. The framework is applicable to automated and non-automated EWSs and
combinations thereof. To address the specifics and needs of a wide variety
of EWS designs, a classification of EWSs is provided, which focuses on the
degree of automations encountered in varying EWSs. The framework and its
implementation are illustrated through a series of example applications of
EWS in an alpine environment. |
