The adoption of the European Directive on Flood Risk Management (Directive 2007/60/EC), has meant a change concerning how to address the mitigation studies of damage. In this regard, until 2007 fragmented approaches of the problem, mainly founded on partial analysis of the hazardousness, and in which risk management was mainly based on the design of structural measures (e.g. flood control channels, levees and floodwalls, reservoirs) were put into practice. The transposition into Spanish law of the Floods Directive (RD 903/2010) has led to the adoption of integrated systems of risk management, in which the premise that there is zero risk is assumed. As a result, the measures to be applied should have as ultimate goal partial mitigation of risk. In connection with the above, resilience provides a convenient framework for this purpose.
To this end, it is essential:
Reduce the uncertainty of the flood risk analysis and flood.
Develop non-structural measures of risk management that complement the structural ones.
Assessment of resilience.
Based on this background, this project has as overall objective to improve the resilience of urban areas against the occurrence of floods. To do this, new methodological approaches will be applied in order to enable realistic characterization of uncertainty in risk analysis. Likewise, during the risk assessment process the subjective component of the analysis will be considered, which is as a result of the perception that society has about risk. To ensure the reduction of vulnerability, while improving resilience of urban areas, management measures will be developed both structural and nonstructural, and based on cost-benefit analysis.
To carry the overall objective out, will be combined methods:
1. Analysis of hazard and risk.
2. Risk management.
3. Characterization of resilience. To this end, we have designed a work plan that includes 18 tasks or activities:
- Use of meteorologic radar information to improve knowledge of the spatiotemporal variability of rainfall that trigger flood events.
- Improving of the frequency analysis using dendrogeomorphologic and historical methods.
- Analysis in regions with lack of hydrometeorologic data.
- Characterization of factors that amplify the magnitude of flooding.
- Post-event analysis.
- Hydrological modelling.
- Hydrodynamic modeling.
- Incorporating floating solid load in the hazard analysis.
- Analysis of social vulnerability.
- Analysis of economic vulnerability.
- Risk mapping.
- Risk mitigation.
- Uncertainty analysis.
- Cost-benefit analysis.
- Qualitative / quantitative analysis of the social perception of risk.
- Analysis of contents in media.
- Development of guidelines for an effective risk communication.
- Quantification of resilience.
To test and validate these methodologies several study sites ubicated at various locations in the upper basins of the Alberche and Tiétar rivers (Sierra de Gredos), Eresma river (Sierra de Guadarrama) and Tagus river (Iberian System), as well as Spanish Mediterranean area (Barranc de Carraixet, Rambla de Poyo, Rambla de Castellana, Rambla de Gallinera and Río Vernissa) will be used. Additionally, post-event campaigns will be carried out in the geographical context of the Iberian Peninsula.
