Grid-to-Grid model estimates of river flow for Great Britain driven by UK Climate Projections 2018 (UKCP18) Regional (12km) data (1980 to 2080) v2

Gridded hydrological model river flow estimates on a 1 km grid over Great Britain for the period Dec 1980 - Nov 2080. The dataset includes monthly mean river flow, annual maxima of daily mean river flow (water years Oct to Sept), along with the date of occurrence, and annual minima of seven-day mean river flow (years spanning Dec-Nov), along with the date of occurrence (units: m3/s). The data are provided in gridded netCDF files. There is one file for each variable and ensemble member. To aid in

Useful for

Use cases llm-inferred
FRA climate-change flow context: modelled monthly and annual flows for a site's 1 km cell under UKCP18 RCP8.5 · Low-flow assessment for water resources or abstraction: 7-day annual minima and their timing from 1980-2080 · Peak-flow trend evidence for drainage and flood-risk climate allowances: annual maxima by ensemble member · Catchment flow time series for ecological or water quality impact screening where gauge records are absent
Audience llm-inferred
flood consultants · hydrologists · water resources engineers · drainage engineers · GIS analysts

Limitations

Constraints llm-inferred
Modelled rather than observed flows; validate against gauge records before design use · Single emissions pathway (RCP8.5) in this record · Twelve-member perturbed parameter ensemble of one regional climate model, so ensemble spread is the main uncertainty · Covers Great Britain only; Northern Ireland is a separate related dataset, though catalogue regions list United Kingdom · Requires netCDF-capable tools; no API or MCP access · Scripted download needs a personal access token
