| Zusammenfassung |
| Inland water management agencies of the German "Länder" address flood forecast and
prevention in order to mitigate flood risks. Additionally their risk management
activities also address assessment of low flow situations (droughts) and freshwater
resources availability. Hydrometeorological services for these hydrological applications
are operationally provided by the Deutscher Wetterdienst (DWD) and comprise:
High spatially and temporally resoluted observational monitoring products and
quantitative predictions of precipitation, evaporation and snow cover (storage and
melting).
The DWD hydrometeorological services processing chain spans from in situ and remotely
sensed observations via numerical weather forecast to runoff models. The best
precipitation analysis for Germany is achieved by combining weather radar and in situ
observations; this QPE product ’RADOLAN’ is available near-realtime on an hourly
basis. It is currently being spatially extended to cover transboundary river basins in
the hydrological catchment area of Germany and will also be used in nowcasting
mode.
The NWP model COSMO-DE uses RADOLAN precipitation analysis products and
provides precipitation forecasts in 2.8 km spatial resolution. Ensemble based weather
predictions providing forecast uncertainty information are more and more accepted by
hydrological users. The model SNOW uses precipitation observations in order to improve
snow melt forecasts. Time series of precipitation and extreme value statistics complete the
hydrometeorological services supporting risk management and climate change assessment in
Germany. |
