In this report we develop a GIS-based multicriteria flood risk assessment and mapping approach. This approach has the ability a) to consider also flood risks which are not measured in monetary terms, b) to show the spatial distribution of these multiple risks and c) to deal with uncertainties in criteria values and to show their influence on the overall assessment. The approach is tested for a pilot study at the River Mulde in Saxony, Germany. Therefore, a GIS-dataset of economic as well as social and environmental risk criteria is built up. Two multicriteria decision rules rare used to come to an overall assessment and mapping of flood risk in the area.
