“…To overcome the limitations posed by traditional hydrological techniques in these environments, tracer approaches can be of high value. Stable isotopes of water (18O/16O, 2H/1H) are considered as ideal tracers of hydrological processes due to their presence within all parts of the hydrosphere and the simplicity and rapidity of sample collection and analysis (Bajjali, Clark, & Fritz, ; Bhat & Jeelani, ; Clark & Fritz, ; Hao et al, ; Yi et al, ). The ability of stable water isotopes, resulted from a temperature‐based fractionation, to quantify evaporation has been asserted in several studies as effective hydrological tracers (Longinelli & Selmo, ; Euliss, Ned, & Mushet, ; Price, Swart, & Willoughby, ; Vreča, Bronić, Horvatinčić, & Barešić, ).…”

Understanding the hydrologic connectivity between kettle holes and shallow groundwater, particularly in reaction to the highly variable local meteorological conditions, is of paramount importance for tracing water in a hydro(geo)logically complex landscape and thus for integrated water resource management. This article is aimed at identifying the dominant hydrological processes affecting the kettle holes' water balance and their interactions with the shallow groundwater domain in the Uckermark region, located in the north-east of Germany. For this reason, based on the stable isotopes of oxygen (δ 18 O) and hydrogen (δ 2 H), an isotopic mass balance model was employed to compute the evaporative loss of water from the kettle holes from February to August 2017.Results demonstrated that shallow groundwater inflow may play the pivotal role in the processes taking part in the hydrology of the kettle holes in the Uckermark region.Based on the calculated evaporation/inflow (E/I) ratios, most of the kettle holes (86.7%) were ascertained to have a partially open, flow-through-dominated system. Moreover, we identified an inverse correlation between E/I ratios and the altitudes of the kettle holes. The same holds for electrical conductivity (EC) and the altitudes of the kettle holes. In accordance with the findings obtained from this study, a conceptual model explaining the interaction between the shallow groundwater and the kettle holes of Uckermark was developed. The model exhibited that across the highest altitudes, the recharge kettle holes are dominant, where a lower ratio of E/I and a lower EC was detected. By contrast, the lowest topographical depressions represent the discharge kettle holes, where a higher ratio of E/I and EC could be identified. The kettle holes existing in between were categorized as flow-through kettle holes through which the recharge takes place from one side and discharge from the other side.

“…When precipitation occurs, however, they are less affected by non-equilibrium fractionation caused by sub-cloud secondary evaporation. The slopes and intercepts of equations (7) and (8) are higher than those of equations (5) and (6), respectively, indicating that the LMWL is related to the scale of precipitation and that small-scale precipitation tends to have lower slopes and intercepts. This occurs because during a small precipitation event, it is difficult for the atmosphere to reach saturation; therefore, the atmosphere is susceptible to sub-cloud secondary evaporation, making the fractionation ratio of D and 18 O lower than 8:1.…”

“…Although the ratio of stable isotopes in water is small, it is sensitive to environmental change and is widely used in hydrology, meteorology, ecology, and paleoclimatology [1][2][3][4]. In the study of the modern water cycle, stable isotope technology plays an important role in tracing the moisture sources of atmospheric precipitation, determining the sources of rivers and lakes, distinguishing groundwater recharge sources, indicating evapotranspiration, and separating runoffs [5][6][7][8][9].…”

Samples of hydrogen and oxygen stable isotopes in precipitation collected and analyzed during the summer monsoon in 2017 and 2018 in Chengdu are reported in this paper. Increasing (decreasing) trends of isotope values (δD and δ 18 O) occur from May to June (September to October), and the valleys occur from July to August. The correlation between δD and δ 18 O for both precipitation events and monthly average precipitation is significant, with high R 2 values (≥0.98). The differences in regression lines may be due to the comprehensive influence of moisture sources, transport path and sub-cloud processes. Combining the d-excess values of precipitation and air mass trajectories generated by the HYSPLIT model, precipitation with a low (high) d-excess value and a more (less) negative δ 18 O corresponds to moisture from ocean (inland) sources. The δ 18 O-temperature (T) and δ 18 O-precipitation (P) correlations are not significant and vary greatly among different periods, which may be attributed to the mutual masking of different effects and the influence of atmospheric circulation processes. The results imply that the negative values in biological and geological proxies may be related to warmer climate, higher precipitation and a larger contribution of oceanic monsoon precipitation, but cannot indicate the changes in temperature and precipitation quantifiably.

“…The linear distribution of δ 2 H and δ 18 O in river water along the Global Meteoric Water Line (GMWL) is considered as evidence of the meteoric origin [23]. Consequently, the isotopic composition of river water can be associated with precipitation, temperature, altitude, and snow/glacier melting [24][25][26]. Also, the interaction between groundwater and surface water can be traced by H and O isotopes [27,28].…”

Climate changes and other human activities have substantially altered the hydrological cycle with respect to elevation. In this study, longitudinal patterns in the stable isotopic composition (δ2H and δ18O) of Lancang River water, originating from the Qinghai–Tibetan Plateau, are presented, and several controlling factors in the wet season are hypothesized. Lancang River water δ2H (−145.2‰ to −60.7‰) and δ18O (−18.51‰ to −8.49‰) were low but close to those of the Global Meteoric Water Line. In the upper reaches of the river, δ2H decreased longitudinally, potentially due to groundwater inputs and melting ground ice in the headwater zone and to an increasing proportion of glacier meltwater with decreasing elevation. In the middle reaches of the river, δ2H values increased slowly moving downstream, likely due to shifts in precipitation inputs, as evidenced by the isotopic composition of tributaries to the main stream. In the lower reaches of the river, the isotopic composition was relatively invariant, potentially related to the presence of large artificial reservoirs that increase the water resident time. The results reveal different hydrological patterns along an alpine river in central Asia associated with both natural and anthropogenic processes. Understanding the degree and type of human interference with the water cycle in this region could improve water management and water security.
