Spatial modelling of tangible and intangible losses in integrated risk analysis—results of the XtremRisK project

XtremRisK — Integrated Flood Risk Analysis for Extreme Storm Surges at Open Coasts and in Estuaries: Methodology, Key Results and Lessons Learned

“…1 and Oumeraci, 2004] for the two pilot sites by considering the selected storm surge scenarios determined in SP1 for present (2010) and future climate conditions (2100). For this purpose, however, a proper methodology for the assessment of intangible losses (social, cultural and environmental losses), their GIS-based spatial modeling and their integration with the economic losses obtained from SP3 into integrated risk maps is required [Dassanayake and Oumeraci, 2010;Burzel et al, 2012]. Therefore, a consistent GIS-approach (cellbased risk assessment (CRA)) for the spatial modeling of risk needs to be developed [Burzel et al, 2012.…”

Therefore, a consistent GIS-approach (cellbased risk assessment (CRA)) for the spatial modeling of risk needs to be developed [Burzel et al, 2012. The CRA approach is also applied for the modeling of direct and indirect economic damages resulting from SP3, for the GIS-based mapping of the risk related to each damage category, and finally for the integration of all risk categories in an integrated risk map for the two pilot sites.…”

“…Moreover, the results have particularly contributed to identify the lack of appropriate methodologies for the evaluation of both cultural and environmental losses as well as for their integration with other losses in risk analysis. Therefore, a systematic framework and methods for the assessment of intangible losses and their integration with tangible losses have been developed and implemented for the two pilot sites [Dassanayake et al, 2012a;Burzel et al, 2012].…”

“…The results are then integrated in a cultural loss assessment matrix (CLAM) by using a five-point score scale varying from very low (1) to very high (5). The spatial analysis of intangible social losses (loss of life, injuries and cultural losses) was successfully performed for the pilot site in Hamburg [Burzel et al, 2012].…”

Danish risk management plans of the EU Floods Directive

“…Here, in close collaboration between the DCA and the German Leichtweiß-Institute for Hydraulic Engineering and Water Resources at TU Braunschweig (LWI), the XtremRisk 'cellbased risk assessment' (CRA) method and mapping based on a 'Source -Pathway -Receptor' (S-P-R) approach [9][10][11] was further developed for Danish conditions [8,[12][13]. Subsequently, hazard, vulnerability and risk maps have been incorporated into risk reduction and risk management plans by the involved 22 municipalities in the 10 risk areas in 2014-2015 (Denmark is divided into 98 municipalities of which 76 have a coastline).…”
