“…The high standard deviations of parameter values for subcluster B1 and B2 explain that multiple sources and complex hydrochemical processes have played a role in generating the water chemical composition (Ma et al, 2014). The samples of subcluster B4 showed the maximum concentration of Ca 2+ , HCO 3 -, and Si, demonstrating strong water-rock interactions (Kim et al, 2020) and weak hydraulic exchange with lake water. In the Piper diagram (Figure S2), the aquitard in reclaimed farmland does not overlap with the lake water, only the aquifer was distributed closer to the lake water.…”

“…Groundwater represents the third most abundant component in the global water cycle, along with oceans and snow/glaciers. Groundwater and snow/glaciers comprise more than 97% of all fresh water on Earth (Kim et al 2020). Moreover, they are one of the most important sources of drinking water, used for various purposes such as agriculture, industry, water supply to the population, etc.…”

The study investigates an interaction of groundwater flow and foundation piles located in the vicinity of the Danube River. The piles represent an obstacle to the groundwater flow, causing the backwater effect upstream, whilst increasing the local flow velocity. On the other hand, high flow velocity around the piles can cause the suffusion of the surrounding soil in the long term, thus significantly reducing the shaft resistance of the piles. A 3D model of groundwater flow and its impact on the piles was developed in the software package GMS.9.2 based on MODFLOW 2005. It was calibrated by comparing the water level values obtained as a result of the simulations with varying filtration coefficient inputs with the observed values in the monitoring well. After the calibration process, piles were implemented into the model and the underground flow was simulated at the study area location for the calibrated year 2006. The impact analysis was carried out by comparing the groundwater level change over time in the pile zone in three control points, in cases with and without the piles, along with the flow net analysis at the location of the piles themselves. The obtained results indicate an absence of the influence of piles on the groundwater flow at the study area location, both in terms of critical flow velocities and in terms of a possible backwater effect upstream.

“…Revealing the geochemical records of mafic rock weathering in particularly cold and dry regions such as Continental Antarctica and the sub-Antarctic has been the focus of intensive research (Marra et al 2015, Kim et al 2020), as they have implications for the effects of changing climatic conditions on the global carbon cycle on Earth and for sedimentary processes on Mars dominated by a basaltic crust (Rutledge et al 2018, Thorpe et al 2019).…”

We used a multidisciplinary approach integrating major, trace and rare earth element geochemistry, mineralogy of rocks and sediments along with the ionic composition of water reservoirs of Admiralty Bay, King George Island, to evaluate the record of water-rock interactions under Maritime Antarctic conditions. Our results showed that the ionic compositions of the streams and meltwaters predominantly reflect the atmospheric inputs, while lake waters have higher Na/Cl, Ca/Mg and HCO3/Cl ratios related to chemical weathering in lake sediments, but this did not allow for distinguishing purely silicate sources. Consistent with the trace and rare earth element data, various alteration indices and Index of Compositional Variability values denote the low degree of chemical weathering in the lake sediments. The records from the previously unexplored Mud Lake and Upper Lake suggest that the lakes of Admiralty Bay are better places to trace the impacts of a succession of environmental changes that have occurred in the watershed, while the stream channel sediments, when accompanied by water chemistry data, may provide a more representative composition of the source rocks than the lake sediments. These findings may help revealing the intensity of contemporary weathering in a colder climate with relatively few mineralogical changes accompanied by a lesser degree of elemental loss.
