Special Issue Information

Dear Colleagues,

Water is crucial for the existence of nearly all life on earth. Although our planet is known as the blue planet and water storage seems large enough for human community consumption and eco-environment maintenance, many parts of the world are experiencing a water crisis due to the aftermath of climate change, precipitation decrease, excessive exploitation and serious pollution. It is estimated that approximately 1.8 billion people in the world may face severe water scarcity in the near future. The availability of water resources is constrained by the quantity and quality of water. A deep understanding of these two aspects underpins the sustainable management of water resources.

With the rapid development of isotope and tracer techniques, great achievements have been made in hydrology and hydrogeology in the past few decades. This progress has greatly supported communities in understanding the behaviors and evolutions of the hydrosphere on Earth under dramatically anthropogenic and natural disturbances and contributes to the rational management and sustainable exploitation of water resources around the world. Studies on the application of isotope techniques in hydrology and hydrogeology are essential for tackling challenging water issues in the future.

This Special Issue aims to publish high-quality studies on the application of isotope techniques in hydrology and hydrogeology. Isotope tools, coupled with other approaches such as laboratory and field experiments, and numerical modeling to understand physical and chemical processes of the hydrosphere, are highly welcome in this Special Issue, as are original research articles and reviews. Research areas may include (but are not limited to) the following:

  • Application of isotope techniques in hydrology and hydrogeology
  • Physical and chemical processes related to water movement;
  • Understanding water cycle via isotopes;
  • Surface water and groundwater interaction;
  • Watershed hydrology;
  • Water contamination;
  • Hydrology and hydrogeology in arid region;
  • Multiple approaches for tackling water issues of various environments;
  • Thermal water circulation;
  • Sustainable water management;
  • Tracing water and substance circulation.

We look forward to receiving your contributions.

Geothermal resources have been a source of significant clean energy in the world. The Sichuan Province is famous for its abundant geothermal resources in China, especially in western Sichuan. The Aba area is a significant minority region in northwestern Sichuan with abundant geothermal resources. In this study, hydrochemical and D-O analyses were conducted on the eight collected geothermal springs to investigate the genetic mechanism of the geothermal resource in the Aba area. The exposed temperatures and pH values of the geothermal springs ranged from 23 °C to 48 °C and from 6.6 to 9.5, respectively. Based on the hydrochemical characteristics, the eight geothermal springs were classified into two types: class A and class B. The class A geothermal springs belonged to the hydrochemical type of Ca-Mg-HCO3-SO4 and Ca-Mg-HCO3 and were affected by the weathering and dissolution of carbonate and silicate. The class B hydrochemical type of geothermal spring was Na-HCO3, which was determined by the weathering and dissolution of evaporite and silicate. A Na-K-Mg triangle diagram revealed that the geothermal springs belonged to immature water. A chalcedony geothermometer indicated that the temperature of the class A shallow geothermal reservoir in the Aba area was 59.70–73.00 °C and 70.65–120.91 °C for class B. Silicon enthalpy approaches showed that the initial reservoir temperature for class A was 181.36–203.07 °C (mixed by 85.76–89.44% cold water) and 271.74–295.58 °C (mixed by 87.39–87.54% cold water) for class B. The recharge elevation of the geothermal spring was 3415–3495 m as calculated by the D-O isotopes. We have proposed these genetic models of the two typical geothermal springs. The achievements provide a vital reference for the further development of geothermal water and the sustainable utilization of geothermal resources in the Aba area. Full article

Vegetation root water uptake is one of the most central water transport processes along the soil-vegetation-atmosphere interface particularly in (semi-)arid ecosystems. The identification and quantification of root activities and water uptake patterns of arid vegetation remain challenging. This paper aims at the quantitative examination of water uptake behaviors of Nitraria, a prevalent desert species in arid environments, during the growth phase via a multivariate linear mixed model based on water stable isotopes, with a main focus on the time interval from a precipitation pulse. The observations indicate that the precipitation events exert periodic significant pulse-effects on vegetation water uptake through direct absorption (contribution of almost 75%) and activation of deep root activity at a certain depth. While in most occasions without rainfall, Nitraria relies on its extremely extensive shallow roots in surface-near lateral zone (contribution of about 60%) to extract massive soil as well as the hydraulic lifting mechanism to survive drought. Achievements would be beneficial to enhancing the understanding of entangled water transport processes and eco-hydrological feedbacks along soil-vegetation interface in arid ecosystems and contribute to a scientific allocation to water resources with the consideration of ecological protection.

Currently, there is a contradiction between coal mining and protection of water resources, meaning that there is a need for an effective method for discriminating the source of mine gushing water. Ningtiaota Coal Mine is a typical and representative main coal mine in the Shennan mining area. Taking this coal mine as an example, the self-organizing feature map (SOM) approach was applied to source discrimination of mine gushing water. Fisher discriminant analysis, water temperature, and traditional hydrogeochemical discrimination methods, such as Piper and Gibbs diagrams, were also employed as auxiliary indicators to verify and analyze the results of the SOM approach. The results from the three methods showed that the source of all the gushing water samples was surface water. This study represents the innovative use of an SOM in source discrimination for the first time. This approach has the advantages of high precision, high efficiency, good visualization, and less human interference. It can quantify sources while also comprehensively considering their hydrogeochemical characteristics, and it is especially suitable for case studies with large sample sizes. This research provides a more satisfactory solution for water inrush traceability, water disaster prevention and control, ecological protection, coal mine safety, and policy intervention.
