The role of deuterium excess in determining the water salinisation mechanism: A case study of the arid Tarim River Basin, NW China

Hydrogeochemical contrasts between low and high arsenic groundwater and its implications for arsenic mobilization in shallow aquifers of the northern Yinchuan Basin, P.R. China

“…6). A slope of 4.81 for lake water indicates that the evaporation occurs at climatic conditions of 50% relative humidity (Huang and Pang, 2012). It is in good agreement with the average annual humidity of 55% in the Yinchuan Basin (Wu et al, 2008).…”

“…6a). However, the relation between groundwater TDS and d 18 O (or dD) cannot directly be used to examine hydrogeochemical processes because the isotopic compositions of rain water exhibit seasonal variation (Huang and Pang, 2012). For example, it showed the lightest isotopic composition in December (d 18 O and dD: À20.0‰ and À148‰, respectively), and the heaviest values in May (d 18 O and dD values: À3.1‰ and À12.6‰, respectively) in the study area (GNIP, IAEA).…”

Hydrochemical processes in a shallow coal seam gas aquifer and its overlying stream–alluvial system: implications for recharge and inter-aquifer connectivity

“…Following recent work by Huang and Pang (2012) and Guo et al (2014), the d-excess values are presented together with TDS contents to further document the processes driving groundwater salinisation (Fig.4). Two distinctive trends can be observed in Fig.4 Fig.4).…”

Salt dynamics in soil profiles during long-term evaporation under different groundwater conditions

“…Groundwater salinization in coastal wetland is usually caused by the effects of climate change, sealevel rise, and anthropogenic interferences (Pauw et al 2012), while in arid and semi-arid areas evaporation is one of the main factors controlling either groundwater or soil salinity (Huang & Pang 2012;Ohrtman et al 2012). Our experimental setup simulated the typical groundwater conditions in the Yangtze River estuary under the influence of the Three Gorges Project, and thus the results obtained not only illuminate the processes of salt transport in the soil profile, but also provide some reliable theoretical references to build up a countermeasure system against the negative effects of the project.…”
