TL;DR: Browney et al. as mentioned in this paper developed an index for monitoring the trophic status of rivers based on diatom composition ('trophic diatom index', TDI) in response to the National Rivers Authority (England & Wales)'s needs under the terms of the Urban Wastewater Treatment Directive of the European Community.

TL;DR: The principles and practice of sampling are described in relation to the main habitat types encountered in Europe, and it is hoped that these provide a framework that can be adapted to most river types in Europe.

TL;DR: This analysis highlights that there is great potential to enhance assessment schemes through strategic design of monitoring networks and innovation, such as earth observation, and further integrate with other sectoral policies.

TL;DR: Overall, suitability of DNA-based identification is particularly high for fish, as eDNA is a well-suited sampling approach which can replace expensive and potentially harmful methods such as gill-netting, trawling or electrofishing.

TL;DR: The trophic diatom index (TDI) as discussed by the authors is a new index for assessing eutrophication in rivers, which was developed to evaluate the effect of organic pollution on the index.
