Great Britain River Flow Estimates on a 1km Grid (1980-2011)

Gridded hydrological model estimates of river flow on a 1km grid over Great Britain for the period December 1980 to November 2011. The dataset includes monthly mean flow, annual maxima of daily mean flow, and annual minima of 7-day mean flow, produced as part of the UK-SCAPE project. Data are provided in netCDF format with supplementary spatial datasets for catchment areas and flow gauging station locations.

Use Cases

• Modeling long-term hydrological trends based on 31 years of monthly mean river flow data.
• Assessing flood risk based on annual maxima of daily mean river flow.
• Analyzing drought conditions based on annual minima of 7-day mean river flow.
• Spatial analysis of water resources using the provided 1km gridded data and catchment area maps.

Strengths

• Covers a 31-year period from December 1980 to November 2011.
• Provides data on three key hydrological variables: monthly mean, annual maxima, and annual minima flow.
• Spatial resolution is 1km x 1km across Great Britain.
• Includes supplementary spatial datasets for catchment areas and gauging station locations to aid interpretation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified as the last update date is 2026-03-19, which may be a placeholder.
