Source apportionment of annual nutrient and sediment loads to rivers in England and Wales, from the SEPARATE framework
Estimates of discharged loads of nitrogen, phosphorous and fine-grained sediments to rivers in England and Wales from multiple sector sources, reported at Water Framework Directive catchment scale, from the SEctor Pollutant AppoRtionment for the AquaTic Environment (SEPARATE) modelling framework [1]. The SEPARATE framework integrates information on pollutant emissions from multiple sources to provide apportionment and summarises these estimates on the basis of the WFD cycle 2 waterbodies for Eng

Useful for
- Use cases llm-inferred
- Catchment-scale attribution of diffuse vs point-source nutrient and sediment loads for WFD waterbody assessments · Baseline pollutant load context for river diffuse pollution options appraisal · Screening agricultural, urban and sewage/CSO contributions when scoping river quality constraints for a drainage or outfall project
- Audience llm-inferred
- water quality scientists · environmental consultants · hydrologists · catchment planners
Limitations
- Constraints docs-verified
- Individual waterbodies with areas <25 km2 should be treated with caution (about 43% of waterbodies) · Input data dates from 2010 to 2012 · Agricultural and regionally averaged inputs limit accuracy at small waterbody scale · No update frequency stated; dataset is a static 2010-2012 estimate
