The modelled interaction between BOD and channel resectioning in relation to the Average Score Per
Taxon, showing (a) the relationship between ASPT and resectioning at three different BOD levels, and (b) the ASPT
versus BOD under different degrees of channel resectioning. Other variables in the model were held constant at their
median values in the dataset.

causal mechanisms or involving taxa outside core
monitoring (e.g. hyporheic fauna). Conclusions
are severely limited where monitoring data can
only provide rudimentary information, such as
determining the impact of fine sediments from
RHS data. Conversely,
statistical power afforded by some monitoring
data open up a range of opportunities, the
extent of which is not yet clear. Nevertheless,
a growing number of river studies are using
monitoring data and this trend is likely to increase
