Nitrate isotopic values are often used as a tool to understand sources of contamination in order effectively manage groundwater quality. However, recent literature describes that biogeochemical reactions may modify these values. Therefore, data interpretation is difficult and vague. We provide discussion on this topic complement the study using halides comparative tracers assessing an aquifer underneath sub-humid humid region NE Mexico. Hydrogeological information stable water isotopes...
Zona Citrícola is an important area for Mexico due to its citriculture activity. Situated in a sub-humid humid climate adjacent the Sierra Madre Oriental, this valley hosts aquifer system that represents sequences of shales, marls, conglomerates, and alluvial deposits. Groundwater flows from mountainous recharge areas basin-fill deposits provides base supply drinking water metropolitan Monterrey. Recent studies examining groundwater quality study urge mitigation pollution. The objective was...
Non-perennial rivers and streams are ubiquitous. Nonetheless, our understanding of their hydrological patterns is minimal. Hydrological models powerful tools to study characterize patterns, but few can simulate extremes such as non-flow events. We aimed capture accurately the flow intermittency spatial temporal in a Mediterranean river basin with restructured Soil Water Assessment Tool (SWAT+). calibrated model using multi-objective optimization algorithm data from two gauging stations...
Global Climate Models (GCMs) are the main tools used to assess impacts of climate change. Due their coarse resolution, with cells c. 100 km × km, GCMs dynamically downscaled using Regional (RCMs) that better incorporate local physical features and simulate a smaller region, e.g. country. However, RCMs tend have systematic biases when compared observations, such as deviations from day-to-day measurements, mean extreme events. As result, confidence in model projections decreases. One way...
This study is developed in three catchments located Denmark, France and Spain, covering different climate physical conditions Europe. The simulation skill of hydrological models under contrasting evaluated using a Differential Split Sample Test (DSST). In each catchment, are given weight based on their according to robustness considering the DSST results for traditional purpose-specific metrics. Four weighting approaches used, including set evaluation weights applied obtain reliable future...
Abstract. Various methods are available for assessing uncertainties in climate impact studies. Among such methods, model weighting by expert elicitation is a practical way to provide weighted ensemble of models specific real-world impacts. The aim decrease the influence improbable results and easing decision-making process. In this study both hydrological analysed, result research experiment presented using with participation six experts experts. For experiment, seven priori selected from...
Two large-scale catchments in Denmark: Ringkøbing fiord and Mid-Zealand catchments. Future changes hydrological regime, extremes, groundwater levels ecological quality ratio (EQR) for fish were assessed. Based on an ensemble of 17 bias-corrected regional climate models forced by the emission scenario RCP8.5, a dry, medium wet model identified future period 2071–2100. Changes water balances catchments, impacts level ration (fish EQR) evaluated. The impact based integrated, transient, coupled...

In AQUACLEW (Advancing the QUAlity of CLimate services for European Water), a project funded by JPI Climate and ERA-NET Consortium 'European Research Area Services (ERA4CS), we examined different ways improving usability existing across Europe tackling key aspects in improvement: user engagement, lack resolution, uncertainties, need an evaluation. The rationale is based on interactive process between service developers users seven study cases assessing implications Service' advancement...
Evapotranspiration is an important process in the water balance. It accounts for transported from surface of Earth to atmosphere. For practical applications, estimation evapotranspiration limited by potential (PET), which maximum that occurs when availability on unlimited. PET can be estimated based different climate variables. When assessing change projections, models often project directions such Furthermore, reliability model projections varies each variable. Therefore, uncertainty...

<p>It is common practice to apply some form of bias correction climate models before use in impact modelling, such as hydrology. The standard method evaluate the based on a cross validation procedure with two or more sub-periods. This allows be assessed data not previously seen calibration step. However, split-sample setups, most likely similar regime data. In effect, evaluated same it calibrated, and informs little about performance outside current...
<p>Commonly, the analysis of climate change impacts on hydrology involves a series steps that begin with General Circulation Model followed by application downscaling or bias correction method and then coupling outputs to hydrological model. Nevertheless, frequently models employed in these analyses are not tested assess their skill simulate catchment under changing regimes. We evaluate such applying Differential Split Sampling Test (DSST) using available observations. The...
