Mediterranean basins face significant water scarcity which demands examining long-term data to prospect their trends in availability and quality. This study focuses on The Onyar River (Inner Catalan basins, NE Spain), explore its historical streamflow changes, the influencing climatic land-use factors, consequential impacts We analyse key hydro-climatic variables—streamflow, precipitation, temperature, evapotranspiration (both PET AET)— across a 60-year span (1960 -2020) relationship with recent stream chemistry (2007-2020). compare these patterns changes land use, variations demand according urban livestock, crop production estimates. Our findings highlight consistent decline streamflow, most pronounced over last two decades, accompanied by an increase PET, probable decrease groundwater recharge. Notably, co-occurred higher concentrations of river ammonium nitrate. attribute use such as afforestation intensive fertilization, well increased withdrawal, particularly during irrigation seasons. Additional factors include growing discharges treated wastewater back into system. offers comprehensive overview declining quantity quality River, attributing interplay anthropogenic factors. underscore need for integrated resource management strategies mitigate implications changes.

Abstract In this contribution we quantify the potential to reduce discharge of excess nutrients with European wastewater, by modelling pollution, greenhouse gas emissions and costs measures under various scenarios. We analyse two types strategies, namely extending requirement nutrient removal broader areas increasing efficiency nitrogen phosphorus. As former strategy usually entails some infrastructural investment while latter an optimization existing processes, imply different costs, shows a better cost–benefit ratio. any case, actions are expected pay for themselves in terms benefits they bring abating water pollution (for nitrogen) emissions. Nitrogen becomes even more attractive whenever investments that assume may be avoided, thanks possibility optimized use infrastructure. Phosphorus become progress technologies its recovery from wastewater sludge, increase demand fertilizers other industrial uses.

Nitrate pollution and eutrophication remain pressing issues in Europe regarding the quality of aquatic ecosystems safety drinking water. Achieving water goals under Water Framework Directive (WFD) has proven to be particularly challenging agricultural catchments, where high nitrate concentrations are main reason for failure many bodies meet a good ecological status. Canals ditches common man-made features irrigated drained landscapes and, when vegetated, have recently been identified as denitrification hotspots. By combining experimental data GIS-based upscaling estimation, potential capacity canal network reduce loads was quantified several scenarios differing level extent length conservative management practices implemented. The analysis carried out lowlands Po River basin, which is largest hydrographic system Italy global hotspot nitrogen inputs eutrophication. Scenario simulations showed that maintaining vegetation at least 25 % length, selecting sites with availability (>2.4 mg N L-1), would promote greater permanent removal. increased load reduction target required achieve WFD status waters draining into Adriatic Sea during spring-summer months, risk higher. Promoting by postponing mowing in-stream end growing season could an effective mitigation strategy improve basins contribute achieving goals.

Abstract The deterioration of superficial water quality is a significant concern in management. Currently, most European rivers do not achieve qualitative standards defined by Directive 2000/60/EC (Water Framework Directive, WFD), while the health status many surface bodies remains unknown. Within this context, we propose new methodology to perform semi-quantitative analysis pressure state river, starting from easily accessible data related anthropic activities. proposed approach aims address endemic scarcity monitoring records. This study proposes procedure (i) evaluate relative different human activities, (ii) identify allocation points pollutant sources along river using raster-based approach, and (iii) determine spatial biochemical index. developed index expresses overall induced that may simultaneously impact single segment. includes establishments under so-called Seveso activities subjected IPPC-IED discipline, wastewater treatment plants, contaminated sites. has been tested over three Northern Italy, each exposed industrial anthropogenic pressures: Reno, Enza, Parma. A comparison with monitored yielded convincing results, proving consistency reproducing variability quality. While additional investigations are necessary, can serve as valuable tool support decision-making processes predictive studies areas lacking or having limited data.
