فعالیتهای صنعتی و شهری منجر به تولید فاضلابهایی میشوند که حاوی مقادیر قابل توجهی ترکیبات آلاینده هستند. تخلیه این فاضلابها به محیط زیست بهصورت تصفیه نشده پذیرفته نیست و لازم است تخلیه مطمئن و عملیات تصفیه روی این فاضلابها انجام گیرد. اما این تخلیه مطمئن گاهی محدود به کمیتها و اعدادی کلی است که صرفا در قالب حداکثر مقادیر مجاز استاندارد بروز مینماید و گاهی مبتنی بر استانداردهای معقولی است ...
As the WFD requires carrying out regular quality assessment of fish population, in the frame of this study sampling was done in 3 sites along Lumebardhi i Pejes river. A list of species composition is completed. Altogether 9 fish species and lamprey (Eudontomyzon stankokaramani) were present in catch. The classification of the ecological status is done by using EFI index. The Lumebardhi i Pejes...
The implementation of the EU Water Framework Directive (EU-WFD) forms the background of the WAgriCoproject (Water Resources Management in Cooperation with Agriculture). WagriCo concentrates on the development of nitrogen management options adapted to hydrological and agro-economic site conditions and at demonstrating new participation approaches and technologies suitable for settingup programme...
Recent metabarcoding work in European rivers, including our own studies of Mediterranean rivers Catalonia (Pérez-Burillo et al. 2020), has shown promising agreement between morphology- (LM) and DNA-based (HTS) assessments diatom periphyton for the Water Framework Directive. However, 10 out 164 Catalan sites we analysed, ecological status class was downgraded from “Good”/ “High” with LM to “Mode...
This work intended to assess the adaptability of bioassay with Raphidocelis subcapitata be used as a complement water quality assessment parameters reservoirs imposed by European Water Framework Directive (WFD). Thus, samples Portuguese (Miranda, Pocinho, Aguieira, and Alqueva) were analyzed in three sampling periods (spring autumn 2019, spring 2020). A physical chemical report waters was also ...
Abstract Airborne LiDAR bathymetry offers low cost and high mobility, making it an ideal option for shallow-water measurements. However, due to differences in the measurement environment laser emission channel, received waveform is difficult extract using a single algorithm. The choice of suitable processing method thus extreme importance guarantee accuracy bathymetric retrieval. In this study,...
Based on historical and WFD-compliant data, the recent inter-annual ecological status long-term chemical-physicochemical quality trends of eighteen characteristic Greek rivers have been assessed interpreted in view implementing EU environmental policies evolution human pressures. Considering predominating poor most river outflows, strengths weaknesses WFD implementation highlighted. The decreas...
The European Union Water Framework Directive (WFD) encourages water managers to implement active stakeholder involvement achieve sustainable management. However, the WFD does not describe in detail how member states should operationalize participation. need for local experience and understanding of collaborative governance (co-governance) processes remains. WaterCoG project evaluated 11 pilot s...
The European Union adopted the Water Framework Directive (WFD) in year 2000 to tackle rapid degradation of freshwater systems. However, biological, hydromorphological, and physico-chemical water quality targets are currently not met, identifying successful policy implementation management actions is key importance. We built a joint species distribution model for riverine fish Flanders (Belgium)...
To combat the persistent eutrophication in coastal waters, sustainable sea-based measures are recommended. Yet, they subject of controversial stakeholder discussion, which hampers implementation and planning process. The aim this study is to evaluate if a participatory mapping (PM) approach ecosystem service assessments (ESA) can be suitable tools within Water Framework Directive (WFD) support ...
