Supplementary Data for Fine Sediment Impact Study on 29 River Sites in England and Wales

Supplementary files for a 2026 study evaluating seven fine sediment measurement methods across 29 river sites in England and Wales. The research, authored by Morwenna Mckenzie, investigates how sediment method, substrate composition, and spatial scale influence the detection of ecological impacts on benthic invertebrate communities. The files are published under a CC-BY 4.0 license.

Use Cases

• Comparing the performance of rapid resuspension-based sediment monitoring methods versus more resource-intensive techniques.
• Analyzing associations between fine sediment and invertebrate metrics at different spatial scales (reach vs. patch).
• Evaluating the influence of substrate composition (cobble, pebble, granule) on sediment-invertebrate relationships.
• Assessing the sensitivity of functional diversity metrics versus taxonomic indices to fine sediment pressure.

Strengths

• Study design includes 29 river sites, providing a multi-site comparison.
• Evaluates seven different fine sediment measurement methods, allowing for methodological comparison.
• Explicitly tests variables including spatial scale, substrate type, and taxonomic resolution.

Limitations

• Data is provided as supplementary PDF files; column-level documentation and raw data structure are absent.
• Row count and specific data formats beyond PDF are unknown, limiting suitability assessment.
• The dataset is small (472.7 KB), indicating limited scope, likely containing summary tables or figures.
