The Water Framework Directive 2000/60/EC (WFD) requires Member States of the European Union (EU) to use a pool bioindicators, that is, Biological Quality Elements (BQEs), including fish species and each State shall, in fact, certify compliance with ecological quality goals WFD. New Italian Index Ecological Fish Communities (NISECI) is WFD-compliant index for analysis BQE river water bodies, bot...

The classification according to the Water Framework Directive (WFD) includes numerous challenges in contrast with the previously applied water qualification standards. The most important element of the ecological status, the biological one, is based on five groups of living organisms: phytoplankton, phytobenthon, macrophytes, macro-invertebrates and fish. The results of a three-year research pr...

This paper is the second part of the study. In Part I, self-similar solutions of a weighted fast diffusion equation (WFD) were related to optimal functions in a family of subcritical Caffarelli-Kohn-Nirenberg inequalities (CKN) applied to radially symmetric functions. For these inequalities, the linear instability (symmetry breaking) of the optimal radial solutions relies on the spectral proper...

Enrichment of nutrients and metals in seawater associated with anthropogenic activities can threaten aquatic ecosystems. Consequently, nutrient and metal concentrations are parameters used to define water quality. The European Union's Water Framework Directive (WFD) goes further than a contaminant-based approach and utilises indices to assess the Ecological Status (ES) of transitional water bod...

River restoration is becoming a priority in many countries because of increasing the awareness of environmental degradation. In Europe, the EU Water Framework Directive (WFD) has significantly reinforced river restoration, encouraging the improvement of ecological status for water bodies. To fulfill the WFD requirements, the Spanish Ministry of the Environment developed in 2006 a National Strat...

By now, all European freshwater and coastal marine ecologists should be familiar with the European Directive 2000/60/EC establishing a framework for Community action in the field of water policy, which is commonly referred to as the Water Framework Directive (WFD). The purpose of the directive is to establish a framework for the protection of inland surface waters, transitional waters, coastal ...

The proposed EC Water Framework Directive (WFD) incorporates some new concepts in the field of water protection. Most of these concepts rely on the use of applied ecology of water ecosystems. The most important feature is that the classification of water quality is to be based on direct biological measurements of ecosystem health. It means that real biological communities should be sampled and ...

The implementation of the European Union Water Framework Directive (WFD) requires nationally generalizable estimates of the benefits of protecting inland and coastal waters. As an alternative to benefit transfers and meta-analyses, we utilize national recreation inventory data combined with water quality data to model recreation participation and estimate the benefits of water quality improveme...

Through implementing environmental Directives, Europe has moved towards coordinated and integrated catchment-to-coast management, following the most novel legislation on ecosystem-based approaches worldwide. The novel joint synthesis of this direction reviewed here allows us to regard the Water Framework Directive (WFD) as a 'deconstructing structural approach' whereas the Marine Strategy Frame...
