WFD River Water Body Catchments: Cycle 3 Classification 2019

2019 classification data for Water Framework Directive (WFD) River Water Body Catchments, including coastal catchments for areas draining directly to the sea. The polygon dataset defines land areas where surface run-off flows to a specific point in a watercourse or coastal water. It provides attribution for the 2019 classification results and was created using hydrological models based on Environment Agency LiDAR data.

Use Cases

• Assessing water body ecological status based on 2019 classification results.
• Modeling pollutant runoff pathways using defined catchment boundaries.
• Identifying coastal drainage areas for small streams and beaches via the 'water_body_type' field.
• Planning river basin management measures for specific water bodies referenced by 'water_body_id'.

Strengths

• Includes both river and coastal catchments, with coastal areas defined for streams under 10km2.
• Based on detailed hydrological models informed by high-resolution EA LiDAR data.
• Contains specific attribution for the 2019 WFD Cycle 3 classification.

Limitations

• Key metadata such as row count, column names, and license details are unavailable across all sources.
• The shapefile format is noted to have unspecified limitations.
• The 'last updated' date conflict (2026-04-07 vs. null) suggests potential metadata inconsistency.
