Flood simulator
Work Package 4

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:

  • For this purpose there is a need to set up a robust system, which operates stable and requires little maintenance.
  • To provide up-to-date data, it should be the aim to achieve low computational complexities obtaining a highly efficient system.
  • Despite all mathematical simplifications the results to be obtained should be sufficiently detailed and all uncertainty factors should be determined.
  • For the operative use and the human operation, a high user-friendliness for non-numerical experts in terms of a clearly arranged presentation of the information is needed.
  • The possibility to modify data format or implement further components requires a system with high flexibility.
  • For end user acceptance it is recommendable to apply on existing models and corresponding programs.
