Flood risk analysis comprises the three basic analyses: reliability analysis, hydrodynamical analysis, and analysis of the consequences. Within the analysis of the consequences the quantification of the failure probability for coastline`s structures is determined. Therefore, failure probabilities due to external loads are used, which have been developed successfully for sea dikes. Within the hydrodynamical analysis numerical flooding areas as well as water levels and flow velocities are determined. In the final step, the hydraulic factors are transformed into consequences for people and property (damage potential). These three basic analyses are combined within the self-developed software ProMaIDes (Protection Measure against Inundation Decision Support). Up to now the software has been applied and verified successfully for many places at the German North Sea and Baltic Sea Coast.
The WP4 objective is the development of a flood simulation for flooding scenarios and damage potentials as a real-time function. Therefore, the existing modules of the software package PROMAIDES should be implemented in the GeoPortal. Furthermore, it should be adjusted and extended to process the real-time data from WP 1 – 3. To identify site-specific hazards, issue early warnings, and implement disaster preparedness activities, it has to be ensured that the flooding simulator meets the following requirements:
