Coastal flood risk: Integration of intangible losses in flood risk analysis

Flood risk is generally defined as the product of the flooding probability and the possible losses associated with the flood event. Flood losses are categorized as tangible and intangible depending on whether or not the losses can be assessed in monetary values. Up to date, intangible loses are not or only partially incorporated in flood risk analysis due to the lack of appropriate methodologies for their evaluation and integration with tangible losses in the overall risk analysis. Therefore, within this research study, methodologies for the evaluation of intangible losses due to flooding and their integration with tangible economic losses in risk analysis were developed .This paper focuses on the integration methodology which was developed within the framework of a GIS based multi-criteria analysis, including the results of a spatial analysis which was exemplarily performed for the different flood losses and integrated losses for a selected pilot site in Hamburg, Germany

XtremRisK: integrated flood risk analysis for extreme storm surges at open coasts and in estuaries: key results and lessons learned

A brief overview of the joint research project XtremRisK is given. The project has been focusing on developing/improving/expanding the knowledge, methods and models with respect to (i) physically possible extreme storm surge for current conditions and scenarios for climate change, (ii) failure mechanisms of flood defenses, (iii) assessment of intangible losses (social and ecological) and their integration with direct/indirect economic losses, (iv) reliability analysis of flood defense systems and (v) source-pathway-receptor (SPR)-based integrated flood risk analysis involving both tangible and intangible losses and its implementation for two selected pilot sites (representative for an open coast and an urban estuarine area in Germany). The key results are briefly summarized and the lessons learned for future flood risk studies are finally drawn
