National River Flow Archive Catchment Boundaries
Download/Access
Catchment boundaries for all the National River Flow Archive (NRFA) gauging stations. The National River Flow Archive provides access to flow data for 1500 gauging stations across the UK, as well as information on the gauging stations and their catchments, including catchment statistics on land cover, geology, rainfall and altitude. Catchment boundaries can be downloaded individually for each station, or a bulk extraction can be requested from the NRFA help desk via email.

Provenance & quality
The catchments have been derived from CEH's Integrated Hydrological Digital Terrain Model (IHDTM). The outlet points (i.e. gauging station) used to define the catchments do not correspond precisely with the locations of the NRFA Gauging Stations, as they have been snapped to the closest IHDTM flow accumulation grid cell. The catchments were derived using the TSTCD program, an in-house algorithm also used to generate the catchments in the FEH CD-ROM.
