HochwassergefahrST

The "HochwasserhazardST" app is used to inform the public 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 a flood. Since the app is for citizen information, it is free.

The flood risk maps of the state of Saxony-Anhalt are visualized in the map area with the "HochwasserhazardST" app. The classified water depths of areas that are flooded during a flood event are shown. The display can be selected for 3 defined scenarios with different probabilities of occurrence. In addition to the HQ100, which statistically occurs once every 100 years, the effects of the flood probabilities HQ10 and HQ200 can be illustrated. Accordingly, the areas do not show any past events, but instead represent calculation results with a defined statistical probability of occurrence.

Within the map display, current water levels can be called up at the gauge location in the app by touching the gauge symbols. Further level information can alternatively be found on the website of the state's flood forecasting center. In the event of flooding, the level symbols are colored according to the alarm levels currently reached for the flood notification levels.

The flood protection dikes that are the responsibility of the state can also be displayed. Touching the dyke line opens the relevant master data for the respective dyke section. Either topographical maps or satellite images can be set as the background (base map).

The "Location view" and "Country view" buttons can be used to switch between the specific location of the user and the country overview. There is also a legend at the bottom of the sidebar that explains what is shown on the map. The sidebar is scrollable.
