| Zusammenfassung |
| The development and implementation of a real-time flood forecasting system in
the context of the Piemonte Region's hydro-meteorological operational alert
procedure is described. The area of interest is the Upper Po River basin
(north-west Italy) of approximately 37000 km2 and its river network of about
3000 km and three big lakes. FloodWatch, a GIS-based decision support system
for real-time flood forecasting, has been developed and used operationally at
the Piemonte Region's Room for the Situation of Natural Hazards in Torino,
Italy, since January 2000. The system is linked directly to the telemetric
gauges system, uses daily quantitative precipitation and temperature
forecasts issued by the Regional Meteorological Service and automatically
supplies operational forecasts of water-level and discharge at about 30
locations for up to 48 hours. Strengths and limits of the system and its link
with operational flood alert and management are discussed. The case study
presented is the October 2000 flood event, when the north-west of Italy
experienced one of the largest floods on record. Results highlight how the
uncertainty linked to the use of meteorological forecasts greatly influences
the quality of the hydrological forecasts. The proposed alert procedure,
based on coded risk levels, can help effectively in facing forecast
uncertainties. |
