Sample sizes by study reach and their altitude (as metres above sea level, MSL), river flow (as Q values, m3 s−1; CEH, 2016), and average score per taxon (ASPT, as a measure of biological water quality), mean concentrations of ammonia (mg N L−1), nitrate (mg L−1) and phosphates (mg L−1) in 2009 (Environment Agency, 2009).
|Reach||n||MSL (m)||Q10||Q50||Q95||ASPT||NH3||Nitrates||Phosphates||Mean width||Mean depth (m)|
Data presented for the River Severn section of the reach, rather than the River Teme (Fig. 1).
