Abstract The EU Commission published on the 26th of October 2022 its proposal for amending three central water management Directives, Water Framework Directive, Groundwater and Directive Environmental Quality Standards. introduces a series amendments changes to remedy shortcomings that were identified in previous fitness check European legislation align legal framework with scientific technical...
RATIONALE Trace levels of natural and synthetic steroid estrogens estrone (E1), 17β-estradiol (E2) and 17α-ethynyl estradiol (EE2) have been demonstrated to exert adverse effects in exposed organisms. E2 and EE2 have been proposed for inclusion in the Water Framework Directive (WFD) list of priority pollutants; however, the detection and accurate quantification of these compounds provide signif...
Maintaining and improving water quality is key to the protection and restoration of aquatic ecosystems, which provide important benefits to society. In Europe, the Water Framework Directive (WFD) defines water quality based on a set of biological, hydro-morphological and chemical targets, and aims to reach good quality conditions in all river bodies by the year 2027. While recently it has been ...
The implementation of the Water Framework Directive (WFD), requires Water Resource Managers to characterise and assess the status of surface water bodies and apply management practices in order to achieve Good Ecological Status (GES), at a national scale. GES is assessed by considering the biological, hydromorphological and physico-chemical characteristics of a water body. There is a need for a...
High spatial resolution hyper-spectral imagery (CASI) and light detection and ranging (LiDAR) imagery acquired for the tidal River Carron and Forth estuary, Scotland, were used in conjunction with field surveys to assess the feasibility of monitoring hydromorphology and human alterations with satellite and airborne remote sensing data. The study was undertaken in the context of the European Uni...
This research examines the emerging role of 'planning for sustainability' in the context of river catchment management. The overall aim is to test the SuNstainable Pathways Design process, with a view to developing a tool kit that encourages stakeholder participation in integrated catchment planning. The recently enacted European Union Water Framework Directive (WFD) offers an unparalleled oppo...
Water authorities are currently preparing the second river basin management plans to improve water status in Europe according to the Water Framework Directive (WFD). The on-going efforts of wetland constructions are related to historical efforts in draining land and lakes for agriculture. In Sweden, one of the major problems for surface water is eutrophication caused by diffuse pollution of nit...
The multiple protocols that have been developed to characterize river hydromorphology, partly in response to legislative drivers such as the European Union Water Framework Directive (EU WFD), make the comparison of results obtained in different countries challenging. Recent studies have analyzed the comparability of existing methods, with remote sensing based approaches being proposed as a pote...
