Modelling water and sediment chemistry in urban canals using chironomid pupal exuviae
… were suitable to classify canals in terms of water and sediment chemistry. The fourth was to analyze potential boundaries between Water Framework Directive (WFD) classes and develop a method to calculate ecological quality ratios that will support the objectives of the WFD. Calibrated …

Environmental impact of mine drainage and its treatment on aquatic communities
… mine drainage is used to discern the effects of water and sediment related variables and elucidate the most important variables in the impact of mine pollution on freshwater macroinvertebrate communities. The implications of this are to be considered for improving mine water remediation …

Spatial and temporal water quality in the River Esk in relation to freshwater pearl mussels
… to river environments. This work addresses the water quality in the River Esk (North York Moors National Park) and its impact on biodiversity, namely the rare, declining population of freshwater pearl mussels (Margaritifera margaritifera). Water quality parameters were monitored both spatially …

Outcomes of river rehabilitation on instream hydraulics and fish communities
… biota present. Following the emergence of the EC Water Framework Directive (WFD) and EC Habitats Directive (HD), there has been an increase in river rehabilitation schemes to ameliorate anthropogenic pressures of rivers and augment ecological status to meet specific obligations. However, despite …

Investigation of bacterial community composition and abundance in a lowland arable catchment
… and abundance. Bacterial abundance increases as water moves downstream, while bacterial diversity decreases as water moves downstream. Some operational taxonomic units (OTUs) become commoner as the water moves downstream (3rd and 4th order streams). This presumably reflects the fact that these …

Using seaweed assemblages on intertidal rocky shores to assess the ecological status of Andalusian coasts. Biogeographical implications.
According to the Water Framework Directive (WFD), the ecological status of European coastal waters must be assessed using different biological quality elements (BQE). One of the four proposed BQE is based on the composition and abundance of the marine macroalgae. Because of the biogegraphical …

A water quality model for shallow river-lake systems and its application in river basin management
… basin management. TRAM aims at describing the water quality of individual water bodies, using problem- and scale-adequate approaches for representing their hydrological and ecological characteristics. The need for such flexible water quality analysis and prediction tools is expected to further …

Multimetric assessment of freshwater macroinvertebrate communities in Flanders, Belgium
One of the objectives of the European Water Framework Directive (WFD; EU, 2000) is to attain a good status for all surface waters in the European Union by the end of 2015. To this end, the ecological status of natural surface waters should be assessed, based on a number of biological quality …

The water framework directive, paradigm shift or unrealized promises? A critical evaluation of its implementation from a boundary, economic and socio-political perspective
The approval of Directive 2000/60/EC, better known as the Water Framework Directive (WFD), resulted from efforts to create a coherent approach to water policy at the European scale. It requires surface waters (rivers, lakes, wetlands and transitional and coastal waters) to attain good ecological …
