FLOOD RISK ASSESSMENTS - RESULTS, APPLICATIONS AND FUTURE REQUIREMENTS

[摘要] This paper summarises and discusses the key results of two research projects one of which was a 4-year joint research project in Germany (XtremRisK) and the other comprised applications of the XtremRisK results to selected cases in Denmark (HARIMA-DK) within the framework of the European Flood Directive on the generation of hazard and risk maps for preselected areas. The former project focused on improving and expanding the existing knowledge, methods and models on flood risk assessments for extreme storm surges with respect to (a) extreme storm surge for current conditions and scenarios for climate change, (b) failure mechanisms of flood defences, (c) assessment of tangible and intangible losses, (d) integrated flood risk analysis involving the aforementioned developments and its implementation for two selected pilot sites (representative for an open coast and an urban estuarine area in Germany). The HARIMADK project used these results, applied it and produced flood risk maps for selected coastal areas in Denmark. The key results of both projects are briefly summarised, lessons learned are discussed and some conclusions for future flood risk studies are finally drawn.
