Headwater stream erosion data from the Environment and Rural Affairs Monitoring & Modelling Programme, Wales, 2021-2023
This dataset consists of headwater erosion process data for sites across Wales between 2021 and 2023, collected as part of the Environment and Rural Affairs Monitoring and Modelling Programme (ERAMMP) National Field Survey. Data include the classification and extent of erosion features. Headwater stream survey data was collected from 101 x 1km squares across Wales, collected as part of the Environment and Rural Affairs Monitoring and Modelling Programme (ERAMMP) National Field Survey.

Useful for
- Use cases llm-inferred
- Headwater erosion baseline for Welsh catchment diagnostic and land-management reports · Sediment and erosion source context for diffuse pollution or water quality assessments in Wales · Upland erosion evidence for flood risk and drainage assessments in headwater catchments
- Audience llm-inferred
- hydrologists · ecologists · environmental consultants · planners · GIS analysts
Limitations
- Constraints llm-inferred
- Wales only · Survey window is 2021-2023 only; no ongoing or later update is stated · Site and square locations are generalised to 10 km grid square centres for landowner confidentiality, so not suitable for site-level precision · Stratified random sample of 1 km squares; not all squares contained headwater streams, so the stream sample is smaller than the square count · Only CSV is listed; no GIS-native format is stated · Licence conflict between ENTRY metadata and DOCS; confirm licence before reuse
