Action plan in case of dike failure

The methodology will include a framework for action plans and illustrations of the methodology in one or more study cases. The action plan will include: description of conditions (hydrological, topographic, geotechnical data), potential causes of dike failure, and hypotheses about possible damages to dikes. The hypotheses will be based on the size of the flood, the area in which the dike is prone to failure and the size of the breach.
Technology validated in lab.
Basic technological components are integrated to establish that they will work together. This is relatively “low fidelity” compared with the eventual system. Examples include integration of “ad hoc” hardware in the laboratory.
The methodology is currently being developed and will be tested in case studies. These case studies are considered as "lab tests". Future ambitions for operational testing include validating the methodology through flood emergency excersises with involvement of authorities and the population.

How does it work?

Flood protection dikes can be subject to increased failure probabilities during floods, especially for floods that may last for months (such as the Danube River). The methodology underlying the action plan provides a clear structure to include information such as the possible failure mechanisms (the breaches that can be formed and the time of their formation), their propagation in the exposed area, the maximum flood extent for different failure mechanisms, and the effective actions that can be taken by responsible authorities. The action plan will be used when probability of dike failure increases. Depending on the real situation (the size of the flood, zone were possible failure of dike, the breach/ brake mode, etc.), the authorities will have the possibility to choose from the presented options in the plan, which increases the effectiveness of disaster management and reduces flood damages.
