Fluvius is a real-time streamflow forecasting tool developed by AIAQUA. It combines numerical weather prediction (ICON model) with machine-learning hydrological models to produce 24-hour discharge forecasts for catchments in South Tyrol.

For each basin and release time, the system provides:

• Mean streamflow forecast with ensemble uncertainty band (p10–p90)
• Bias-corrected precipitation forecast per weather station
• Bias-corrected temperature forecast per weather station

Forecasts are updated every day, aligned with ICON model release 06.
