Monitoring the qualitative status of freshwaters is an important goal international community, as stated in Sustainable Development Goal (SDGs) indicator 6.3.2 on good ambient water quality. data are, however, lacking many countries, allegedly because capacity challenges less-developed countries. So far, relationship between human development and for quality monitoring have not been analysed systematically. This hinders implementation fine-tuned programmes monitoring. Against this...
Abstract Stream water temperature is an important factor used in quality modeling. To estimate monthly stream on a global scale, simple nonlinear regression model was developed. It applied to temperatures recorded over 36-yr period (1965–2001) at 1659 globally distributed gauging stations. Representative air were obtained from the nearest grid cell included new meteorological forcing dataset—the Water and Global Change (WATCH) Forcing Data. The reproduced with efficiency of fit 0.87. In...
Abstract A methodology for estimating the loading of pollutants to water courses across all pan‐Europe, an area reaching River Don in east and including some Mediterranean rim countries near North Africa is presented. Loadings come from point (domestic effluent, manufacturing discharge urban runoff) diffuse (scattered settlements land use) sources. The loads have been calculated on a countrywide basis using readily available data held by national international bodies. These are downscaled...
Ensuring ecosystem resilience is an intuitive approach to safeguard the functioning of ecosystems and hence future provisioning services (ES). However, a multi‐faceted concept that difficult operationalize. Focusing on mechanisms, such as diversity, network architectures or adaptive capacity, has recently been suggested means operationalize resilience. Still, focus mechanisms not specific enough. We suggest conceptual framework, trinity, facilitate management based in three distinctive...
Meeting ecological and water quality standards in lotic ecosystems is often failed due to multiple stressors. However, disentangling stressor effects identifying relevant stressor-effect-relationships complex environmental settings remain major challenges. By combining state-of-the-art methods from ecotoxicology aquatic ecosystem analysis, we aimed here disentangle the of chemical non-chemical stressors along a longitudinal land use gradient third-order river Germany. We distinguished...
Abstract To address the continental and large‐scale aspects of water quality assessments, new modelling approaches are required. This paper describes development a continental‐scale model river – WorldQual. Simple equations, consistent with availability data on continental‐scale, used to simulate response biochemical oxygen demand (BOD 5 ) total dissolved solids (TDS) anthropogenic loadings flow dilution. A methodology is developed that appropriate for scenario analysis global scale. Average...
Abstract The sustainable development goals (SDGs) constitute an ambitious comprehensive global framework including monitoring mechanisms and indicators to evaluate progress towards precise targets of development. Most European countries have adapted their national sustainability indicator systems conform the UN Agenda 2030 for development, introducing new frameworks governance processes in which these are embedded. What do we know about political struggles implementing this important...
A mathematical simulation model (ICECREAM), describing the phosphorus cycle in soil and its losses fromsoil to water, was developed applied clayey soils Finland. The is based on CREAMS GLEAMS model,with some modifications adapt it local (climatic) conditions. original erosion submodel (USLE) highly overestimatederosion for Finnish agricultural with relatively steep slopes (i.e., 7%8%). calibration of poorly knownand/or spatially varying input parameters, such as Mannings n, erodibility,...
Climate change and increasing electricity production affect future freshwater requirements for thermoelectric power plants in Europe. This paper explores the reasons shows ‘hot spots’ further analysis. A scenario simulation approach was selected to estimate water availability uses Europe up 2050. Depending on scenario, withdrawals thermal would increase by 64% or decrease 92% between 2005 At same time, average summer is expected because of climate southern south-eastern parts In these...
Abstract An export coefficient model of diffuse pollution at large scales has been developed as part a larger study investigating and mapping the present future patterns quantity quality European water resources. The was to provide reasonable estimates across whole Europe based on readily accessible datasets, that would be amenable application within gridded loadings surface waters. models for biochemical oxygen demand (BOD), total nitrogen (TN) phosphors (TP) were fitted data from Union...
Purpose The aim of this study is to analyze future changes freshwater needs in the electricity production sector and identify hotspots where cooling water may not be fulfilled. Design/methodology/approach To address goals study, a scenario simulation approach was selected estimate availability uses Europe up 2050. Two SCENES scenarios were cover wide range water‐related driving forces including developments population, GDP, production, technological structural changes, as well climate...
Reservoirs regulate water flow and pollutant transport in catchments. However, climate change can significantly impact their ability to perform this function. This study analysed a multi-decadal time series of data examine the complex relationship between nutrient pollution trends Möhne reservoir catchment. The aimed at understanding effect on downstream face changing climate. analysis revealed that upstream concentrations were higher than downstream, indicating general nutrient-trapping...
Our objective was to incorporate the effects of gypsum on phosphorus (P) losses into field-scale ICECREAM model and simulate treatment 93 ha clayey soil with in a catchment located southern Finland. In addition effects, macropore flow description added ICECREAM. First, sensitivity analysis performed for new parameters, retrieved from literature survey. After this, calibrated reference period by setting parameters correspond P observed experiment. Next, effect line laboratory field...
