Grid-to-Grid model simulations of daily anthropogenically influenced river flows for England and natural flows for Great Britain, 1961-2021
The datasets provide Grid-to-Grid (G2G) hydrological model estimates of daily mean river flow (m3s-1) on a 1 km x 1 km grid. The river flows provided here are generated using the G2G model for Great Britain driven by observation-based meteorological data. They provide spatially consistent simulations of natural and anthropogenically influenced daily mean river flows. The natural flows are for the period 1st January 1961 to 31st December 2021, the observed-anthropogenically influenced flows are f

Useful for
- Use cases llm-inferred
- Natural baseline flow series from 1 km grid cells for FRA at ungauged catchments · Quantifying abstraction and discharge influence by comparing natural and anthropogenically influenced flows (England) · Long-term (1961-2021) daily flow inputs for water resources and drainage outfall assessments
- Audience llm-inferred
- flood consultants · hydrologists · water resources engineers · GIS analysts
Limitations
- Constraints docs-verified
- Anthropogenically influenced flows exist only for England, with observed-influenced flows only for 1999-2014 · Natural flows exclude Orkney and Shetland · Modelled data on a 1 km grid, not gauge observations · Entry licence field says 'Non-Open government licence' but DOCS state Open Government Licence; verify before reuse · No update frequency stated; file download only, no API in DOCS
