“…Given the high population density in this area and the significant rates of groundwater extraction, the shift from surface water to groundwater becomes more pronounced. The soluble ions within the red-layered soil easily undergo dissolution, which results in a notable increase in groundwater TDS in this particular region [31][32][33][34][35][36][37]. A more in-depth examination of the findings revealed that TDS progressively increases in the upper stretches of Chihuai Creek and Majin Creek.…”

The Qujiang River Basin is a significant water system located in Zhejiang Province, China, that serves as a primary water source for Quzhou City. For this research, we collected and examined water samples from the Qujiang River Basin. In this study, we collected and analyzed water samples from the Qujiang River Basin and employed a combination of methods, including water balance analysis; Piper trilinear diagram; Gibbs diagram; and environmental tracer techniques, such as hydrochemical and isotopic analysis. These techniques helped us to analyze the spatial distribution patterns and evolutionary trends of surface water and groundwater hydrochemistry, along with the stable isotopes of hydrogen and oxygen, as well as to determine the sources of surface water and groundwater by calculating the conversion ratio between surface water and groundwater. (1) The findings of our study indicate that the primary hydrochemical types in the study area are Ca-HCO3 and Ca-HCO3·Cl, with the ion composition of water primarily influenced by rock weathering and precipitation. (2) Similar spatial variations in hydrochemical indicators were observed between surface water and groundwater in the study area, with frequent transitions between the two. (3) The hydrogen and oxygen isotope content increases downstream, signifying that both groundwater and surface water in the study area are replenished by atmospheric precipitation, as supported by the relationship between hydrogen and oxygen isotopes and the meteoric water line. (4) We determined that groundwater predominantly replenishes surface water in the upstream area. The average contribution rate of groundwater to surface water is 19.67%, with an annual average recharge volume of 1.23 × 106 m3. Midstream and downstream, surface water mainly recharges groundwater, with an average contribution rate of 22.77% and an annual average recharge volume of 1.59 × 106 m3.

“…Groundwater is not only an essential guarantee of water for human production and life (Huang et al, 2022; Shi et al, 2021) but also has an irreplaceable role in the oasis (Lozano et al, 2013). In the arid zone of northwest China, vegetation in artificial and natural oases is strongly dependent on groundwater (Gries et al, 2003; Martinetti et al, 2021; Tamea et al, 2009), providing vegetation water demand (Wang, Wang, et al, 2018; Wang, Yu, et al, 2018), regulating soil water content (Cao et al, 2021), salinity (Wang et al, 2013), and balancing water use in abundant and dry years (Gao et al, 2020; Wada et al, 2012; Wang et al, 2023). However, climate change (Devkota & Gyawali, 2015; Shrestha et al, 2017; Tan et al, 2017) enhanced the impacts of human activities (Riley et al, 2019; Scanlon et al, 2005), turning groundwater evolution more complex.…”

To accurately obtain the spatial distribution characteristics of groundwater level in an extremely arid zone and its dynamic change patterns under the influence of human activities, based on the data of 55 groundwater observation wells in the middle and lower reaches of the Kriya River, spatial interpolation of regional groundwater level data were performed using the inverse distance weight, spline function, trend surface, and the ordinary kriging methods. The optimal interpolation method was selected by its accuracy to spatially interpolate the groundwater level data in the study area from 2019 to 2021. The results show that: (1) the ordinary kriging method has the highest interpolation accuracy (MAE = 7.1393, MRE = 0.0058, RMSE = 9.4314) and reflects the spatial and temporal variability and distribution characteristics of groundwater levels with great accuracy. (2)The relationship between surface water–groundwater recharge and discharge in different areas of the river channel in the desert section varies depending on geological structure, surface water seepage, and other elements. (3) Groundwater in the Taklamakan Desert has little effect on groundwater recharge in the Dariyabui Oasis, and changes in groundwater dynamics in the oasis are predominantly influenced by surface runoff. (4) Monthly changes in groundwater levels in the Yutian Oasis are continuous, with ‘V’ shaped fluctuations, a declining trend in the southern part, no significant change in the central part, and a slight increase in the northern part. These results contribute to the sustainable management of water resources in the Kriya River Basin, provide a basis for groundwater prediction, and offer a reference for studies of other, similar extreme desert area basins.
