Description In comparison to the classical inundation maps, flood risk maps generate more information about the flooding event because they bring into account the effects of flooding. Risk maps are generated as a mathematical combination of damage maps with different return periods. These maps can be usefull to evaluate policy alternatives and they are an important input for social cost benefit analysis. In this paper, the advantages of the new methodology – an objective comparison between alternatives and between different hydrographical catchments-, the state of the art of the methodology and the opportunities for applications are described. The applications are diverse but, dealing with water management, a diagnose of the current situation and the knowledge of the effects of planned infrastructure and/or land use changes before the intervention is the most important. The basic model, with land use maps as a main input, is refined by introducing important line elements and discrete objects in landscape whose potential damage or damage function is significantly different from their environment.
