Estimates of daily river flows for 95 catchments in Great Britain from the GR6J model under present and future climate scenarios, using large ensemble climate m
This dataset contains GR6J (which stands for modèle du Génie Rural à 6 paramètres Journalier) modelled daily river flow time series for 95 river catchments in Great Britain and driving data (precipitation and potential evapotranspiration calculated from temperature) from the EC-Earth Single Model Initial Condition Large Ensemble (SMILE) climate model. The large ensemble is based on the EC-Earth Global Climate Model (GCM) v2.3 and is run for present day (equivalent to present day climate with obs

What's in it
- Data offered docs-verified
- daily modelled river flow (GR6J), 95 GB catchments · precipitation driving data (EC-Earth SMILE) · potential evapotranspiration driving data (EC-Earth SMILE)
- Coverage docs-verified
- Great Britain (95 river catchments) · 2030-01-01 to 2154-12-25
- Resolution docs-verified
- Daily time step, per catchment (95 catchments), tabular rather than gridded
- Formats docs-verified
- CSV
- Access docs-verified
- Open Government Licence (OGL). Download via the EIDC catalogue; scripted (wget/curl) download needs a personal access token sent as an Authorization: Bearer header.
Useful for
- Use cases llm-inferred
- Baseline daily flow series for FRA or water resources assessments at the 95 modelled catchments · Flow sensitivity under pre-industrial +2°C and +3°C warming for climate change risk assessments · Low-flow and drought frequency analysis using the pooled 2000-year synthetic record
- Audience llm-inferred
- hydrologists · flood consultants · water resources engineers · climate risk analysts
Limitations
- Constraints llm-inferred
- Covers only 95 catchments, not national coverage · Modelled flows, not observed gauge records; each catchment uses its best-performing model run · Driven by a single climate model (EC-Earth SMILE), so climate uncertainty is limited to one GCM · Stated temporal extent (2030 to 2154) does not obviously match the 'present day' scenario; check before use · Scripted download requires a personal access token
