The 20th century brought an exponential increase in bioassessment methods for rivers and estuaries. In Europe, bioassessment methods and classification systems were improved by the publication of the Water Framework Directive (WFD), which also led to the investigation of new biological and more complex indices. As the WFD influenced the development of new methods across the world, European tools were also influenced by methods developed in the USA, Canada, and other parts of the world. In Europe, this progress resulted in the need for an intercalibration process to compare assessments of water bodies. Yet, development of assessment tools for rivers/estuaries and their implementation in national monitoring programs is far from being a reality across the world, even in temperate regions, but specifically in tropical or dry climates. It is not clear how unsatisfactory classifications of rivers/estuaries have led to restoration and mitigation measures and to the improvement in water bodies. Official monitoring programs are still mostly based on structural aspects of communities, i.e., in the taxonomic composition and abundance, whereas the functional assessments are not conducted. Finally, the last years have witnessed an impressive effort to find tools based on molecular data (DNA, eDNA) with the aim of reducing costs and time and obtaining more complete overviews of the ecosystems, including rare or cryptic species that could be neglected by morphological evaluations. All these aspects are included within the scope of this Special Issue.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
