Classic (polybromodiphenyl ethers, PBDEs) and emerging halogenated flame retardants (HFRs) such as decabromodiphenyl ethane (DBDPE) norbornenes, well organophosphate (OPFRs) were analysed in 52 sediments 27 fish samples from three European river basins, namely the Evrotas (Greece), Adige (Italy) Sava (Slovenia, Croatia, Bosnia Herzegovina Serbia). This is first time that FR levels have been reported these basins. The highest contamination was found rivers, whereas lower values obtained for...
Abstract. The European Alps stretch over a range of climate zones which affect the spatial distribution snow. Previous analyses station observations snow were confined to regional analyses. Here, we present an Alpine-wide analysis depth from six Alpine countries – Austria, France, Germany, Italy, Slovenia, and Switzerland including altogether more than 2000 stations 800 used for trend assessment. Using principal component k-means clustering, identified five main modes variability regions...
Study region: The region of interest is the South-Tyrol in southeastern Alps, Italy. A comparison meteorological forcing performed with reference to this while hydrological simulations are conducted Passirio river basin. focus: objective work evaluate suitability ERA5-Land reanalysis product as a dataset for modelling topographically complex Alpine regions. compared observational gridded dataset, obtained by means Kriging interpolation, available at two contrasting spatial resolutions coarse...
This study analyses how indicators of water quality (thirteen physico-chemical variables) and drivers change (i.e., monthly aggregated air temperature streamflow, population density, percentage agricultural land use) coevolve in three large European river basins Adige, Ebro, Sava) with different climatic, soil use conditions. Spearman rank correlation, Principal Component Analysis, Mann-Kendall trend tests were applied to long-term time series data during the period 1990-2015 order...
Abstract. Water temperature in lakes is governed by a complex heat budget, where the estimation of single fluxes requires use several hydro-meteorological variables that are not generally available. In order to address this issue, we developed Air2Water, simple physically based model relate lake superficial layer (epilimnion) air only. The has form an ordinary differential equation accounts for overall exchanges with atmosphere and deeper (hypolimnion) means simplified relationships, which...
Temperature of the surface layer temperate lakes is reconstructed by means a simplified model on basis air temperature alone. The comparison between calculated and observed data shows remarkable agreement (Nash–Sutcliffe efficiency indices always larger than 0.87, mean absolute errors approximately 1°C) for all 14 investigated (Mara, Sparkling, Superior, Michigan, Huron, Erie, Ontario, Biel, Zurich, Constance, Garda, Neusiedl, Balaton, Baikal, in west‐to‐east order), which present wide range...
River ecosystems are subject to multiple stressors that affect their structure and functioning. Ecosystem refers characteristics such as channel form, water quality or the composition of biological communities, whereas ecosystem functioning processes metabolism, organic matter decomposition secondary production. Structure respond in contrasting complementary ways environmental stressors. Moreover, assessing response is critical understand effects on services produce direct benefits humans....
Abstract River water temperature is a key physical variable controlling several chemical, biological and ecological processes. Its reliable prediction main issue in many environmental applications, which however hampered by data scarcity, when using data‐demanding deterministic models, modelling limitations, simpler statistical models. In this work we test suite of models belonging to air2stream family, are characterized hybrid formulation that combines derivation the equation with...
Transport of hydrophobic pollutants in rivers such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and heavy metals is often facilitated by suspended sediment particles, which are typically mobilized during high discharge events. Suspended sediments thus represent a means transport for particle related within river reaches may suitable proxy average pollutant concentrations estimation reach or catchment. In this study, multiple discharge/turbidity events were...
Water resources are under pressure from multiple anthropogenic stressors such as changing climate, agriculture and water abstraction. This holds, in particular, for the Mediterranean region, where substantial changes climate expected throughout 21st century. Nonetheless, little attention has been paid to linkages between long-term trends streamflow quality river basins. In present study, we perform a comparative analysis of recent hydroclimatic parameters nitrate pollution three...

Abstract Assessing the accuracy of gridded climate data sets is highly relevant to change impact studies, since evaluation, bias correction, and statistical downscaling models commonly use these products as reference. Among all studies those addressing hydrological fluxes are most affected by errors biases plaguing data. This paper introduces a framework, coined Hydrological Coherence Test (HyCoT), for assessing coherence with observations. HyCoT provides framework excluding meteorological...
This work introduces a general multi-objective parameter estimation framework to exploit MODIS-based snow cover maps reduce predictive streamflow uncertainty in snow-dominated catchments. The well-known GLUE methodology is applied with approach, combining observations recorded at the outlet section and satellite-derived maps, aggregated fractional values of catchment area. hydrological model used this study includes snowpack routine which exploits statistical representation distribution...
The ongoing transformation of the electricity market has reshaped hydropower production paradigm for storage reservoir systems, with a shift from strategies oriented towards maximizing regional energy to aimed at revenue maximization individual systems. Indeed, producers bid their scheduling 1 day in advance, attempting align operational plan hours where expected prices are higher. As result, accuracy 1-day ahead forecasts started play key role short-term optimization This paper aims...
Water quality is a concern in most river basins worldwide due to the widespread release of pollutants which impacts freshwater ecosystems. Exploring relationships between drivers and water parameters at regional scale key identification appropriate actions for reduction pollution. Regional models are tool achieve this, though their development poses relevant challenges because complexity non-linearity such relationships. Among available approaches, Machine Learning (ML) promising its...
Abstract. Climate change impact studies on hydrological extremes often rely models with parameters inferred through calibration procedures using observed meteorological data as input forcing. We show that this procedure can lead to a biased evaluation of the probability distribution high streamflow when climate are used. As an alternative approach, we introduce methodology, coined “Hydrological Calibration eXtremes” (HyCoX), in which model, driven by model output, is carried out maximizing...
