“…The decrease in water inflow upstream (Wuwei basin) has forced downstream residents to over‐draw shallow groundwater, and the promotion of water‐saving irrigation has also reduced groundwater recharge in the MO area. Irrigation recharge is a major way to recharge groundwater in oasis areas, although groundwater resources are effectively replenished only when the irrigation water utilized is surface water (Crosbie et al, 2013; Hanson et al, 2012; Satish et al, 2020; Stanton et al, 2011; Taylor et al, 2009). The decrease in the groundwater table in the MO area have therefore been significant within this evolving environment (Xu et al, 2006).…”

In order to implement sustainable management of water resources in the Desert Oasis, it is necessary to quantify the changes in the groundwater recharge process. Using the Cl−, stable hydrogen and oxygen isotope datasets extracted from 113 groundwater samples in the years of 2000 and 2020, and combining these with the MixSIAR model, changes in the groundwater recharge process and recharge source contributions in the Minqin Oasis (MO) in northwestern China area before and after ecological treatment were quantitatively analysed. Overall, confined groundwater was the greatest contributor to the recharge of shallow groundwater in the MO area in 2000. However, after 10 years of ecological rehabilitation, surface water has become the most important recharge source of shallow groundwater, with its contribution increasing by 10.6% between 2000 and 2020 ~ 2021. River water diversion projects have reversed falling groundwater levels in the MO area. Of these projects, that in the MO has seen groundwater levels rise at a rate of 0.09 m·year−1 from 2008 to 2019. This coincides with the increase in the contribution of surface water to groundwater recharge in 2020. In addition, insignificant changes were observed in the contributions made by lateral groundwater flow to groundwater recharge in the MO area in the years of 2000 and 2020 ~ 2021, indicating that groundwater in the upper and middle reaches of the MO area have contributed very little to the restoration of groundwater levels in the area's lower reaches. All these factors would appear to indicate that regional ecological management has had a lasting impact, and that the exploitation of groundwater in this desert oasis area in an inland river basin should be based upon rational planning and integrated, comprehensive management strategies.

“…The motions observed by GPS represent the combined response to the entire water column of both local/regional spatial trends and short-/long-term temporal trends. Thus, the geodetic observations of surface loading provide an opportunity to isolate signals associated with specific hydrologic changes that exhibit trends at different temporal scales [e.g., reservoir storage varies at shorter drainage-basin time scales than groundwater, which varies based on a combination of aquifer characteristics (Skøien et al, 2003) and anthropogenic effects (Laveti et al, 2021;Wu et al, 2020)].…”

Drought intensity is commonly characterized using meteorologicly-based metrics that struggle to provide insight into water deficits within deeper hydrologic systems. In contrast, Global Positioning System (GPS) displacements are sensitive to both local and regional hydrologic-storage fluctuations. While a few studies have leveraged this sensitivity to produce geodetic drought indices, hydrologic drought characterization using GPS is not commonly accounted for in drought assessment and management. To motivate this application, we produce a new geodetic drought index (GDI) and quantify its ability to characterize hydrologic drought conditions in key surface and sub-surface hydrologic reservoirs across California. In northern California, the GDI exhibits a strong regional association with reservoir storage at the 1-month time scale (correlation coefficient: 0.83) and groundwater levels at the 3-month time scale (correlation coefficient: 0.87), along with moderate associations with stream discharge at the daily (instantaneous) time scale (correlation coefficient: 0.50). Groundwater in southern California is best characterized with a 12-month GDI (correlation coefficient: 0.77), and reservoir storage is optimized with the 3-month GDI (correlation coefficient: 0.72). Differences between northern and southern California reveal that the GDI is sensitive to unique aquifer and drainage basin characteristics. In addition to capturing long-term hydrologic trends, rapid changes in the GDI initiate during clusters of large atmospheric river events that closely mirror fluctuations in traditional hydrologic and meteorological observations. We show that GPS-based hydrologic drought indices provide a significant opportunity to improve drought assessment, in California and beyond, by improving our understanding of the hydrologic cycle.

“…Thus, the quantity and quality of karst groundwater are very sensitive issues worldwide, affected by meteorological factors and geological factors. However, anthropogenic activity, such as excessive groundwater exploitation, water conservation structure, and alterations in land use/landcover patterns, have significantly altered the hydrogeochemical processes of karst groundwater with the increase in population, the expansion of cities and the development of industry and agriculture [2][3][4]. In China, karst aquifers are widely distributed in the north and south of China, providing abundant good-quality groundwater for living, agricultural irrigation, and ecology [5,6].…”

“…Groundwater's hydrogeochemical evolution in the karst area has the characteristics of complexity, fuzziness, and uncertainty due to the heterogeneity and anisotropy of carbonate strata, which largely depend on natural processes, such as hydrogeological conditions, lithology, the mineral composition of the aquifer and water-rock interactions when anthropogenic activity is less intrusive [4,[8][9][10][11]. However, at present, anthropogenic activity and climate change have obviously affected the hydrogeochemical evolution of groundwater around the world [2,3,12,13]. There are numerous techniques for evaluating the evolution processes of groundwater with the development of the hydrogeochemical research field.…”

Karst groundwater is an important water supply, especially in northern China. With the rapid development of China’s economy, anthropogenic activities have had a significant impact on karst groundwater formation, circulation and other processes. In this paper, the Baotu spring basin, which is closely related to anthropogenic activities, was selected as the research object to carry out a study of water chemical characteristics and evolutionary processes. And, mathematical statistics, Piper trilinear diagram, Gibbs diagram, and ion ratio methods were used to analyze the characteristics and evolution processes of groundwater. The results of this study show that the hydrogeochemical components of karst groundwater are mainly controlled by the weathering of rocks, mainly by the dissolution of carbonate rocks and silicates with the dominant cation of Ca2+ and the dominant anion of HCO3−. Considering the role of anthropogenic activities, including agricultural and industrial activities, the evolution process of karst groundwater is mainly controlled by hydrogeochemical effects such as mineral dissolution and filtration, the mixing of multiple water bodies, anthropogenic activities (domestic sewage, industrial and agricultural wastes), oxidation–reduction and cation alternating adsorption. Moreover, the influence of anthropogenic activities on the formation and evolution of karst groundwater gradually increases, leading to the rise in nitrate content in karst groundwater and accelerating carbonate rock dissolution. The research results of this paper can provide a favorable reference for environmental protection and research on karst groundwater in areas of intensive anthropogenic activity.
