Flood losses might be divided in tangible and intangible losses. Tangible losses are evaluated in monetary values and hence commonly incorporated in flood risk analyses. To date, intangible losses are not or only partially incorporated in flood risk analysis due to the lack of appropriate and generally accepted evaluation and integration methods. This study focuses, therefore on the development of suitable methods to evaluate intangible losses and to incorporate them in flood risk analyses. For this purpose, five categories of intangible losses are considered: loss of life, physical injuries, mental health impacts, cultural losses and environmental losses. For the non-monetary evaluation of loss of life and physical injuries, the method of Penning-Rowsell (2005), initially proposed for river and coastal floods, is selected and further developed in this study for application in spatial analysis. For the non-monetary evaluation of mental health impacts, a novel method based on the main causes for mental disorders of flood victims and exposure to flooding is proposed. However, no recorded data and relationships on mental health impacts associated with other losses and flood conditions are yet available for validation. For the non-monetary evaluation of cultural losses, a new method is developed to consider both physical damage of cultural assets and their cultural values. As no specific methods are available to estimate the level of physical damages of cultural assets or their cultural values, methods are developed based on several assumptions. For the non-monetary evaluation of environmental losses, the ecosystem services approach is adopted and a new ecosystem services damage assessment (ESDA) tables are developed for the estimation of the level of losses of ecosystem services based on ecosystem damages. For the integration of losses within a Multi-Criteria Analysis (MCA) framework, a hybrid MAUT-AHP (Multi-attribute Utility Theory-Analytic Hierarchy Process) approach is selected, which includes the development of value functions. The proposed methods are applied in two pilot sites in Germany, which were selected in the frame of the Joint Research Project ‘XtremRisK’. For several flooding scenarios developed in ‘XtremRisK’, flood losses are estimated, and an integrated flood risk analysis is performed.
