Modelled Headwater Stream Quality Across Great Britain

Modelled estimates of Biological Monitoring Working Party (BMWP) scores for freshwater streams across Great Britain. Data pools observations from two survey years, 1998 and 2007, to model relationships between stream quality and catchment characteristics using a Boosted Regression Tree approach.

Use Cases

• Analyze spatial patterns of BMWP scores across Great Britain to identify regions with high or low water quality.
• Model relationships between stream quality and catchment characteristics using the Boosted Regression Tree methodology described.
• Assess changes in water quality by comparing modelled estimates derived from the 1998 and 2007 survey years.

Strengths

• Data covers headwater streams across the entire geography of Great Britain.
• Modelling integrates observations from two distinct survey years, 1998 and 2007.
• Based on the Biological Monitoring Working Party index, a recognized metric for river biological quality.

Limitations

• Dataset contains modelled estimates, not direct field measurements, introducing uncertainty.
• Temporal coverage is limited to two specific years, 1998 and 2007.
• Original row count, column details, and sample data are unavailable for verification.
