It is of great significance to study their hydrological processes. Based on the stable isotope values of precipitation, soil water and groundwater in the subalpine shrub zone of the eastern Qilian Mountains from May to October 2019, their stable isotope characteristics as well as the recharge and infiltration of soil water were analyzed by the lc-excess method and the lc-excess balance equation. The results showed that stable isotopes of precipitation showed significant enrichment in spring and depletion in summer and autumn, characterized by large fluctuations. Stable isotopes of soil water were enriched in summer and depleted in spring, appearing a tendency of gradual decrease with the increase of soil layer depth. However, stable isotopes of groundwater had the smallest fluctuations. Soil water was obviously recharged by precipitation in summer, but lower recharge was observed in spring and autumn. The main contributors to soil water recharge were precipitation events with the intensities of 10–20 mm/day and 20–30 mm/day. In subalpine shrub zone, both piston flow and preferential flow patterns coexisted in the infiltration of soil water, with a relative contribution rate of 76% from plug flow and 24% from preferential flow to groundwater recharge. The results are of theoretical value and practical significance for understanding hydrological processes and evaluating groundwater quantity in the subalpine shrub zone.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"84 11","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to estimate soil erodibility for various land uses using the K-factor from the Wischmeier equation, assess indicators such as the structural stability index, clay ratio, and dispersion ratio, and develop a predictive model for erosion risk using artificial neural networks (ANN) and geospatial technologies. High-resolution spatial maps of erosion risk were created to inform land management and conservation efforts. An ANN model in MATLAB R2024a predicted soil erodibility as well as indicators such as the dispersion ratio, crust formation, and clay ratio. Statistical analyses, including principal component analysis (PCA) and correlation assessment, were performed with OriginPro 2021b to explore relationships between soil properties. Spatial maps of observed and predicted erodibility were created using ArcGIS 10.7.1.

Even though soil pollution around collieries stands in the shadow of greenhouse gas emissions, the anthropogenic geochemical impact of coal mining will persist for decades to centuries after the coal phaseout. Soils are of paramount significance when assessing the pollution of mining sites. This analysis provides a reference dataset for evaluating soil transformation in coal minescapes. Identification, screening, eligibility check, and extraction of data from articles published in peer-reviewed journals between 2000 and 2022 yielded a comprehensive dataset on the chemical composition of 13,925 soil samples from 55 mined coal fields in 32 countries of Eurasia, Africa, Australia, and the Americas. These carefully handpicked records allowed the calculation of mean concentrations for 41 chemical elements, alongside total organic carbon and a total of 15 rare-earth elements. The resulting dataset is of both fundamental geochemical and policy-relevant significance. The maximum enrichment of contaminated soils with As, Bi, Hg, Sb, and Se reveals the role of coals as the source of highly coalphile elements. Remediation guidelines can benefit from the dataset, e.g., for arsenic whose world average contents fall below the standards of Canada, Russia, and the USA. Regional soil quality criteria may incorporate these figures to update threshold levels for mining sites.

The map was generated through four subindices: lithological, geomorphological, pedological, and hydrological. The quantification method involved overlaying a regular grid (2,5 × 2,5 km grid cells) onto thematic maps representing the subindices, which is the most common method to generate geodiversity index maps. This resulted in five maps: geodiversity index, and the four subindex maps.

Therefore, attention should be given both to the methodological procedures for their creation and to the generated results. The manuscript discusses the selection of subindices; potential errors for counting a single element more than once; the notion that a geodiversity index map may hide areas that are important due to specific components; and the importance of using subindex maps as relevant results and not only as secondary products.

However, soil properties influencing the K factor typically vary smoothly with terrain morphology and the soil catena pattern. Terrain morphology should therefore be taken into account, and it will lead to a more precise spatial distribution of K-factor values, significantly refining soil loss calculations and erosion control planning. For this purpose, the Czech Soil-Morphological Geospatial Database containing 1,417 soil samples was created. All soil samples were analyzed in the laboratory, and their K values were linked to morphometric characteristics (MMCH) based on geographical coordinates. The correlation dependences of the MMCH and spatial changes of K values, as deviations from the average values for the drainage areas within the closed erosion units, were calculated. The results of the methodology validation show a statistically high significant dependence between the K values obtained from field measurements and the values generated by the K-terrain model, created to automate the calculation.

Gushing induced sand inrush in semi-diagenetic surrounding rock under high water pressure is one of the most difficult worldwide disasters during tunnelling. In the construction of Wangjiazhai Tunnel in Lincang-Qingshuihe expressway, gushing and sand inrush disasters in semi-diagenetic surrounding rock occurred numerous times under high water pressure causing serious economic loss, environment influence and construction delay. Conventional grouting reinforcement and drainage measures in tunnel cannot effectively solved the disaster problem resulting in repeated gushing and sand inrush, rescue and re-excavation without confidence construction period. In order to solve the surge and sand inrush disaster problem of the tunnel, this study proposed a surface ultra-deep pumping well dewatering method. The pumping well exceeding 250 m deep was designed and sequentially pumping scheme was adopted adapted to the progress of the excavation face. Three deep wells were successfully installed, and pumping experiments was carried out which inversed hydraulic parameters and confirmed the feasibility of well structure. The pumping capacity of these wells exceeding 700 m<sup>3</sup>/d and a maximum drawdown of 70 m. Based on the field experiments, a sequential dynamic dewatering scheme was proposed. The sequential dynamic dewatering scheme was verified by numerical simulation. The results show that this scheme can reduce the groundwater level above the tunnel by more than 50 m and effectively reduce the groundwater level in front of the tunnel excavation face. The design ideas and results of this study provide a reliable solution for the control of tunnel surge and sand inrush disasters under similar challenges.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"84 11","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12665-025-12245-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
