Literature provides only a few examples of contamination groundwater with microplastics, mainly investigated using chemical approach. Little importance is given to the hydrogeological processes able affect contamination, such as river–groundwater interactions. This study was carried out two aims. The first aim formulation method high result-to-cost ratio, based on aspects area. Microplastics we...

With the growing population and adverse effects of climate change, pressure on coastal aquifers is increasing, leading to a larger risk saltwater intrusion (SI). SI often complex difficult characterize from well data only. In this context, electrical resistivity tomography (ERT) can provide high-resolution qualitative information lateral vertical distribution salinity. However, quantitative int...

Introduction Dense non-aqueous phase liquids (or DNAPLs) are liquids that are water immiscible and at the same time are heavier than water. When a spill occurs, these liquids can migrate into aquifers and become trapped in the pores. Some techniques proved to be efficient for the recovery of DNAPLs from the aquifers. One method is the injection of fluids through injection wells, for example, co...

Background: Anthropogenic activities release high concentrations of heavy metals into the aquatic ecosystems, which can be absorbed by the aquatic organisms. In this study, the accu-mulation of cadmium (Cd) and arsenic (As) was compared in liver, gill and muscle tissues of toothed carp (Aphanius sophiae) in fresh and salt water. Methods: A total of 175 fish samples were collected from the Sh...

We have developed a method for analytically solving the porous medium flow equation in many different geometries for horizontal (two-dimensional), homogeneous and isotropic aquifers containing impermeable boundaries and any number of pumping or injection wells located at arbitrary positions within the system. Solutions and results are presented for rectangular and circular aquifers but the meth...

The calculation of base flow rates in rivers is complex since hydrogeological and hydrological studies should be performed. estimation storm hydrograph associated to various return periods even more challenging compared other events. This research provides a novel methodology compute gaged for extreme events based on statistical correlations daily flows. current does not require aquifers analys...

High nutrient discharge from groundwater (GW) into surface water (SW) have multiple undesirable effects on river quality. With the aim to estimate impact of anthropic pressures and river–aquifer interactions nitrate status in SW, this study integrates two hydrological simulation quality models. PATRICAL models SW–GW RREA streamflow changes due human activity. The were applied Júcar River Basin ...

Assessing water travel times in hyporheic and adjacent alluvial sediments is important to quantify exchange rates, biogeochemical turnover, pollution dynamics across groundwater-surface interfaces floodplain aquifers. Heat 222Rn are useful natural tracers for this purpose. While heat transport commonly simulated via the convection-conduction equation, of often assuming purely advective a homoge...

Aquifers are ubiquitous, and their water is easy to obtain with low extraction costs. On many occasions, these characteristics lead overexploitation due important level declines, reduction of river base flows, enhanced seawater intrusion, wetland affection. The forecasted increase in demands global warming will impact the future availability resources. Conjunctive use surface subsurface waters ...
