“…Piper diagrams, correlation analysis diagrams and ion proportion diagrams were drawn by Origin 2021 software. Through conversion of a single evaporation sample back to the local meteoric water line (LMWL) along the assumed evaporation line, a reasonable estimate of the average source water was obtained, and the estimate of the composition before evaporation was used to obtain an accurate evaporation line (EL) for the water body (Shi et al 2018). The evaporation line slope was calculated based on the Craig-Gordon model (formula) (Benettin et al 2018, Gibson et al 2008:…”

Large-area subsidence lakes in coal mining areas with high phreatic levels in eastern China play a very important role in regulating water resources and improving the ecological environment. These coal mining-related subsidence lakes vary in formation time and connectivity with rivers. These factors may influence the hydrogeochemistry and hydrogen and oxygen stable isotope characteristics of the lake water. This study assessed the hydrogeochemical and hydrogen and oxygen stable isotope characteristics and the influencing factors of the subsidence lake water, surface river water and shallow groundwater in the Huainan coal mine area in eastern China. The results showed that the hydrochemical types of the subsidence lake water and river water are Cl-Na and HCO3•Cl-Na and that the hydrochemical types of the shallow groundwater are mainly HCO3•Cl-Na and HCO3•Cl-Ca. There are no significant differences in the hydrochemical characteristics of subsidence lakes with different subsidence ages and types. The major ions in each water body mainly come from evaporite dissolution and silicate weathering, and ion exchange occurs. Reverse ion exchange occurs in some shallow groundwater samples. The hydrogen and oxygen isotopic compositions of the subsidence lake water, river water and shallow groundwater plot below and to the right of the LMWL and are distributed along a straight line, indicating that these water bodies have a common source, namely, precipitation. With increases in the formation time of the subsidence lakes, the heavy isotopes in the lake water gradually become depleted, and the d value gradually increases, mainly driven by precipitation dilution, weakening evaporation, river recharge and groundwater recharge. The isotopic values of different types of lakes with the same subsidence time differ little. The research results are of great significance for understanding the water cycle and water resource evaluation of coal mining subsidence lakes.

“…Further, with vegetation restoration, the areas of deep‐rooted plants have largely increased and led to a severe depletion in soil water and groundwater (Wang et al ., 2010; Huang et al ., 2013). However, with vadose zones of tens of meters, the deep soil water and groundwater can only be recharged by EPE with great intensities (Liu et al ., 2010; Li et al ., 2017c; Shao et al ., 2018; Xiang et al ., 2020; Ji et al ., 2021; Shi et al ., 2021). From this perspective, EPE is helpful in recharge of subsurface water and sustain vegetation construction in this region.…”

The intensive and frequent extreme precipitation events (EPE) greatly contribute to the severe soil loss in China's Loess Plateau, and it is thus essential to understand how and why EPE varies with space and time. Particularly, the combined influence of multiple factors on EPE has rarely been explored. This study analysed the spatiotemporal variability of EPE for 1961-2017 after defining six indices for intensity, frequency, and duration of EPE (R5d, SDII, R90t, R90n, CDD, CWD). We employed 12 atmospheric circulation factors to determine their combined effects on EPE on different time scales over time by the multiple wavelet coherence. The EPE indices spatially varied with obvious southeast-northwest gradients. Averaged across the whole plateau, SDII, R90t, and R90n increased insignificantly, while R5d, CDD, and CWD decreased insignificantly. In addition, the change trend had spatial variations with most wet EPE indices increasing in the north and the southernmost areas and decreasing in the middle-south areas. SDII, R90t, and R90n at 68%, 66%, and 53% of stations tended to increase, respectively, and R5d, CDD, and CWD decreased at 66%, 70%, and 77% of stations, respectively. The temperature had a greater correlation with the duration of EPE in summer and on the intensity and frequency of EPE in winter. El Niño-Southern Oscillation (ENSO), Pacific North American teleconnection pattern (PNA), ENSO-Arctic Oscillation (AO), and ENSO-AO-PNA were found to be the main factors influencing EPE individually or simultaneously. This study provides technical support for the identification of combined effects of multiple factors, and the results are helpful for regional environmental management. Specific to the Loess Plateau, the identified individual or multiple factors can be used to project future changes in EPE, and the more frequent and intensive EPE in some regions may increase the difficulty in future soil loss control.

“…The properties of subsurface materials regulate the infiltration and run‐off of surface waters (Fan et al., 2020; Lana‐Renault et al., 2007), and affect both river base‐flow (Hector et al., 2015) and water table depth (Wang et al., 2021). The development of ecosystems also strongly depends on this deep compartment, as it controls exchanges in the hyporheic zone (Floury et al., 2019), rooting depth (Shi et al., 2021), diversity of microorganisms (Stumpp & Hose, 2013), and organic matter accumulation or leaching (Jeanneau et al., 2020).…”

Weathering and erosion processes are crucial to Critical Zone (CZ) evolution, landscape formation and availability of natural resources. Although many of these processes take place in the deep CZ (∼10–100 m), direct information about its architecture remain scarce. Near‐surface geophysics offers a cost‐effective and minimally intrusive alternative to drilling that provides information about the physical properties of the CZ. We propose a novel workflow combining seismic measurements, petrophysical modelling and geostatistical analysis to characterize the architecture of the deep CZ at the catchment scale, on the volcanic tropical island of Basse‐Terre (Guadeloupe, France). With this original workflow, we are for the first time able to jointly produce maps of the water table and the weathering front across an entire catchment, by means of a single geophysical method. This integrated view of the CZ highlights complex weathering patterns that call for going beyond “simple” hillslope CZ models.
