Lithium and Boron isotope are number of the "non-traditional stable isotopes", which have become one of the most popular fields and frontiers of isotope geochemistry in recent years (He et al., 2020). large mass differences between Li isotopes and B isotopes lead to large isotope fractionation during geological processes …

The existing studies on water age in alpine catchment focused on investigating the impacts of topography, vegetation, and snow on water age using short-term isotope data, and did not consider the effects of glacier and permafrost changes on hydrological processes (Ceperley et al., 2020, Song et al., 2017, Yang et al., 2021).

Stable isotopes in water of oxygen (16 O and 18 O) and hydrogen (1 H and 2 H) are typically inert and conservative in mixing relationships and used as a tracer to investigate hydrogeological and hydrological processes including groundwater recharge and groundwater–surface-water interaction [14,15].Accordingly, the deuterium excess (D ex) …

The Upper Brahmaputra (UB) and Upper Yangtze (UYA) basins are selected as the study area (Fig. 1).The UB basin is located in the southern Tibetan Plateau (TP) and extends in the ranges of 27-32°N and 82-97°E with an elevation extent of 2900–6900 m a.s.l. (above sea level) (Fig. 1 b).The mean annual precipitation in the UB basin is around …

Meanwhile, the water stable isotopes (δ 2 H, δ18 O) in J 2 z and J 2 y groundwater show obviously consistent depletion in June 2018 (e.g., borehole J17 and SK16).

Stable isotopes provide a useful tool to assess water sources as well as mixing fractions in mine-related environments. For …

Using stable isotope tracers to assess hydrological flow paths, residence times and landscape influences in a nested mesoscale catchment. Hydrol. Earth Syst. Sci. 9, 139–155.

The slope and intercept of LMWL are smaller than those of GMWL (Global Meteoric Water Line: δD = 8δ 18 O + 10), indicating the aridity of the plain area (Craig, 1961). The stable isotopes values of snowmelt water in the mountainous areas are from −84.18 to −37.00 ‰ for δD and from −11.90 to −7.10 ‰ for δ 18 O with the average ...

Here, we constrained a Bayesian mixing model with stable isotope data (2018–2019) in rainfall (N = 704), spring water (N = 96), and surface water (N = 94) with seasonal isotope sampling (wet and ...

central, eastern, and western areas of the basin from July, 2017 to July, 2018 for stable isotope tests; whereas, three of these samples were also used for hydrochemical tests. The samples were filtered through 0.45 μm membranes on Fig. 2 Hydrogeological cross-section (along line A–A′ in Fig. 1) of the study area

Stable and radioisotopes isotopes of water in and around mine complexes can be used to help fingerprint and trace the origin, age, flow, transport and all the complex hydrological phenomena involving water availability and quality. ... for the use of environmental isotope techniques to assess hydrological processes in mining areas …

Here, we explore and evaluate the feasibility of using the stable isotopes of oxygen and hydrogen (18 O, 2 H) to track hydrological processes at an operating oil …

Highlights Stable isotope assessment was performed to evaluate sulfur transformations. Significant enrichment of δ 34 S and δ 18 O in sulfate strongly demonstrated bacterial sulfate reduction. Re-oxidation and disproportionation of reduced sulfur compounds are potential processes. Stable isotope assessment leads to a …

The research results may provide scientific guidance for the rational development and utilization of water resources in coal mining subsidence areas, enrich the study of the hydrological cycle in the area, and are of great significance for the protection of the local water balance and water environment.

Here, we constrained a Bayesian mixing model with stable isotope data (2018-2019) in rainfall ( N = 704), spring water ( N = 96), a … From mountains to cities: a novel isotope hydrological assessment of a tropical water distribution system ... Low δ 18 O rainfall compositions corresponded to the western boundary of the study area, whereas ...

Coal mining may cause considerable environmental problems (Gomo and Vermeulen 2014) including the excessive decline in the elevation of the water table, the drying up of springs near mine sites, the reduction of river levels, and the contamination of groundwater and nearby surface water bodies (Howladar et al. 2017).Consequently, coal …
