The dataset includes five files of UK physical river characteristics including four files of gridded data at 1km × 1km resolution and one comma separated table. The data includes:
- Outflow drainage directions (D8)
- Catchment areas (km2)
- Widths of bankfull rivers (m)
- Depths of bankfull rivers (m)
- NRFA gauging station locations (easting (m), northing (m))

The comma separated NRFA (National River Flow Archive) gauging station locations table provides the best locations of 1499 river flow gauging stations on the 1km grids, together with the approximate error in the 1km × 1km gridded delineation of the upstream catchment area. All datasets are provided on the British National Grid.

Provenance & quality

The 1km × 1km outflow drainage direction and catchment areas datasets are generated from a 50m × 50m resolution digital terrain: IHDTM (Integrated Hydrological Digital Terrain Model). Bankfull river widths on a 1km × 1km grid are generated using the OS MasterMap Water Network Layer width data in a regression relationship with geomorphic and rainfall characteristics. The 1km × 1km gridded bankfull river depth dataset is generated using observed measurements from a range of sources in a regression relationship with geomorphic and rainfall characteristics. Finally, the NRFA gauging station location dataset on a 1km × 1km grid is generated by identifying the location (easting, northing) on the catchment areas dataset that best represents the true gauging station location. An indication of the quality of these data is provided by the % error between the 1km-derived and the IHDTM catchment areas. See supporting information for more details.
