Resumen
Flood risk management requires the analysis of flood defense strategies, which is a complex decision-making process involving many uncertainties. Here, we present a case study where a cost-based methodology is carried out in the Village of Navaluenga (Ávila, Spain). With this aim, a semi-distributed hydrological model, as well as a 1D/2D hydraulic model, have been used, based on different flood hazard scenarios. Flood damages have been assessed by means of depth-damage functions. We have reduced and incorporated into the decision-making process estimation of flood frequency uncertainties by means of dendrogeomorphological analysis of riparian trees. In addition, we also have taken into account observed uncertainties as a result of applying different empirical depth-damage functions. Expected losses associated to each different defense strategy were compared by means of a cost-benefit procedure, where both epistemologies and random uncertainties were incorporated by means of a stochastic approach.
