The app “Flood DangerST” serves to inform the population about the risk of flooding in the state of Saxony-Anhalt. It also provides information on flood protection and what to do in the event of flooding. Since the app serves to provide citizen information, it is free.
The “Flood DangerST” app visualizes the flood risk maps of the state of Saxony-Anhalt in the map area. The classified water depths of areas that are flooded during a flood event are shown. The representation can be selected for 3 defined scenarios with different probabilities of occurrence. In addition to HQ100, which statistically occurs once in 100 years, the effects of the flood probabilities HQ10 and HQ200 can be illustrated. The areas therefore do not show past events, but rather represent calculation results with a defined statistical probability of occurrence.
Within the map display, current water levels at each gauge location can be accessed in the app by touching the level symbols. Alternatively, further level information can be found on the website of the state's flood forecast center. In the event of flooding, the level symbols are colored according to the flood alarm levels currently reached.
