Gridded (1km) physical river characteristics for the UK v2
The dataset includes six files of UK physical river characteristics including five files of gridded data at 1 km x 1 km resolution and one comma separated table. The data includes: • Drainage directions (D8 flow method), ESRI coding • Drainage directions (D8 flow method), unifhy (python hydrology framework) coding • Catchment areas (km2) • Widths of bankfull rivers (m) • Depths of bankfull rivers (m) • NRFA gauging station locations (easting (m), northing (m)) Two versions of drainage directions

Useful for
- Use cases llm-inferred
- FRA baseline catchment area lookup at a site from the 1 km catchment-area grid · Nearest NRFA gauge location and upstream catchment area check for flow transfer · Drainage direction input for catchment delineation in hydrological modelling · Indicative bankfull width and depth estimates for river baseline assessments
- Audience llm-inferred
- flood consultants · hydrologists · drainage engineers · GIS analysts
Limitations
- Constraints llm-inferred
- Gridded at 1 km, coarser than the 50 m source terrain model used for drainage and catchment areas · Catchment areas on the grid carry an approximate delineation error versus the source terrain model · Bankfull width and depth are regression-based estimates, not direct site measurements · Dataset only; no API or MCP tools listed · No update schedule stated; version 2 published 2022-11-08
