Description: Das Projekt "EWASE - Effectiveness and Efficiency of Early Warning Systems for Flash Floods" wird vom Umweltbundesamt gefördert und von Universität für Bodenkultur Wien, Institut für Wasserwirtschaft, Hydrologie und konstruktiven Wasserbau (IWHW) durchgeführt. The overall objective of the proposal is the evaluation of the effectiveness and efficiency of Earla warning systems (EWS) for medium sized river basins prone to flash floods. A cross sectional and interdisciplinary approach is pursued to relate the concept of risk analysis to the development of strategies for flood damage prevention through early warning in flash flood regions. The performance of existing structural protection schemes in the Besòs (Spain) and Traisen (Austria) river basins are reviewed and the potential improvement through the use of EWS will be investigated. Within this scope, the efficiency of the EWS will be analysed and assessed by comparison of two basic factors: the reliability of the provided forecasts and the economic benefit of this information, e.g. in terms of avoided damages. Therefore, on the one hand, the basin specific requirements concerning forecast lead-time and accuracy will be determined through an assessment of flooding risks in the basin. On the other hand, the reliability and value of the provided forecast will be quantified based on the applied forecast methods and modelling approaches taking into account the inherent sources of uncertainty. Eight work packages (WP) are defined. They include the analysis of uncertainties of rainfall forecasts and flood forecasts as well as risk analysis and economic evaluation. In addition to these technical aspects a subjective element is addressed by analyzing the expert's behaviour and role in translating the modul output into warnings and subsequent actions in the case of failures in system operation. The methods are applied in two pilot studies. Finally, the findings are synthesised for generalisation of the approach. An important outcome of the project will be a deliberate and proved concept for the assessment of EWS. Furthermore, the results will concretely contribute to the improvement of the examined EWS in the pilot basins as well as models and software tools of the partners. Also general conclusions and guidelines for the assessment of other operational or projected EWS in similar basins will be provided. The results will be integrated to the FLOODSite project and other current European and national research activities.
