Multi-model seasonal forecasts of river discharge for Europe from January 2021 to present
This dataset provides hydrological seasonal forecasts of monthly mean river discharge across Europe. Two hydrological model ensembles are provided. The first is an E-HYPE multi-model system comprising eight model realisations using a catchment-based resolution. The second comprises the E-HYPEgrid, VIC-WUR and EFAS (LISFLOOD) hydrological models at a 5km gridded resolution. The initialisation of the hydrological seasonal forecast uses the European Flood Awareness System (EFAS) daily gridded meteo

Useful for
- Use cases llm-inferred
- Seasonal low-flow and drought outlook for water resources screening in European catchments · Monthly flow tercile context for flood risk assessment background · Seasonal discharge scenarios for reservoir or water-supply planning studies
- Audience llm-inferred
- hydrologists · water resources engineers · flood risk consultants · environmental consultants
Limitations
- Constraints llm-inferred
- Monthly means only; no daily or sub-monthly discharge · Europe-wide; no UK-specific coverage stated in the docs · Two model ensembles with different resolutions (catchment vs 5 km grid) need comparison before use · Bias-adjusted for E-HYPE and VIC-WUR only · NetCDF-4 output needs processing for GIS or spreadsheet workflows · Login required to access the data on the platform
