Water level information system FLYS

”What will the water level be at a random place of a water body depending on the run-off?“ In order to answer this classic hydrologic question, the Federal Institute for Hydrology (BfG) has developed the river hydrology software FLYS. FLYS is not a hydraulic flow regime but processes model results as well as the geographical data and the geo specialist data which formed the basis for the modeling. FLYS unites various modules under a common user interface:

• WINFO: WINFO can derive the water levels for each run-off at any point of the course of the river on the basis of known water levels of previous modeling projects.

• DIAGRAM: The module offers the possibility to show data and results from WINFO in different views (e.g. longitudinal section, cross profile, discharge curves, continuous curves).

• FLOOD MAP: With the GIS-tool, water levels produced in WINFO can be rendered as areas and flooding boundaries can be compared.

• FIXATION ANALYSIS: The change of the water level - run-off relationship over time along the course of the river can be evaluated with this expert tool.

Thus, FLYS constitutes a comprehensive system for information and analysis for different groups of users which is still easy to operate. In the scope of the LABEL projects the user requirements shall be taken better into account. Some of the goals of the project are making FLYS available to a wider range of users as web application, improving the functions and implementing new modules. The expansion of the database for the Elbe catchment area will also be realized.
