Periphyton' benthic macroinvertebrates and fish arte common indicators in river biomonitoring, which can be used separetely oor contemporaneously. Their importance in the ecosystem and advantages for biomonitoring have been described in ref. below. The commonly used biomonitoring approaches include diversity, biotic indices' multimetric approaches' multivariate approaches' functional feeding groups ( 9FFGs ) and multiple biologicaal trials.. Among these techniques' biotic indices and multimetric approaches are most frequently used to evaluate the environmental health of streams and rivers.

Here are a few papers that deal with assessment of lakes and rivers in Europe. In short, primary producers (phytoplankton and benthic algae) are good indicators of elevated nutrients, benthic invertebrates (general degradation, e.g. land use and associated stressors like nutrients, fine sediments, loss of riparian habitat), macrophytes (nutrients, water level fluctuations) and fish (connectivity).
I can help you wit our sotver Water Quality Index (Canadian) to evaluate the quality of rivers waters! And i wish contribute in your scientific works!
Do not hesitate to ask for any help about QWI, bicose this for me is a common professional thing. I want to help you with that!
I wish you a beautiful sunny day!

Thank you for the offer, but I do not need help.
Assessment of the ecological state of the Lower Section of the Dnieper River and the Lower Section of the Ingulets River was performed on the Integrated index of the ecological state (IIES) in accordance with the fishery standards, as the most sensitive to changes in the ecological state of the river.
Integrated index of the ecological state (IIES) is formed on the basis of existing standards and also includes maximum permissible concentrations (MPS).
From the blocks of water quality indices, the first includes indices that don’t have the effect of total action (summation), the remaining blocks include indices that have this effect. According to the sanitary norms, the effect of total action is possessed by substances of the first and second classes of danger with the equal limiting indices of harmfulness (LIH). According to the fishery norms substances with the equal LIH without taking into account the classes of danger are analyzed.
