Based on monitoring data from 2007 to 2019, the responses characteristics of typical metal ions (i.e., Fe, Mn, and Ba) in the phreatic aquifer of the recharge area were investigated. After two years of recharge, the groundwater within 150 m from the riverbank was completely replaced by reclaimed water. With increasing groundwater level and the input of organic carbon, a reductive zone was formed within 50 m from the riverbank and the intensity of sulfate reduction became steady in this zone after 2010. Within the reductive zone, reductive dissolution of Mn in minerals and the desorption of adsorbed Ba in the solid phase resulted in the concentrations of both being significantly higher than those in reclaimed water during the period 2008–2010. After 2010, the concentrations of both decreased significantly and tended to stabilize. With regard to Fe, the combined effects of reductive dissolution of Fe in minerals and FeS precipitation caused the Fe concentration to approach that of reclaimed water. Beyond the reductive zone, Fe, Mn, and Ba concentrations exhibited no significant spatial variations along the groundwater flow path. In the optimized electron trapping capacity (<i>ETC</i>), the variation of sulfate makes the greatest contribution. In the reductive zone, <i>ETC</i> effectively indicated the concentration changes of Fe, Mn, and Ba in groundwater.

Statistical analysis, Piper diagrams, Gibbs diagrams, and ion ratio methods were applied to investigate the hydrochemical features of the river and analyze the sources of water ions.

In general, a downstream increase of ion concentrations was apparent, alongside with human pressures. However, the ion concentrations were merely influenced by seasonal variations. The hydrochemical signature of surface water is principally controlled by rock weathering processes, in which silicate weathering is the dominant source of major ions, with carbonate weathering co-contributing.

The formation of landslide dams, or landslide deposits, functions as a part of cascading geohazards. Recent studies have revealed the effects of landslide deposits on aquatic geochemistry and ecosystems. However, the role of landslide deposits in shaping subsurface redox conditions, closely linked to biogeochemical element cycles, remains unexplored. Herein, we applied electrical resistivity tomography (ERT) and self-potential (SP) surveys to investigate the subsurface structure, groundwater flow patterns, and redox conditions of a landslide deposit formed by shallow landslides that occurred during the 2018 Hokkaido Eastern Iburi earthquake in Japan (M_w 6.6). The ERT results revealed the soil–bedrock interface as a zone of 20–40 Ω·m with an abrupt spatial change. The soil zone had a maximum thickness of ~ 8 m and a groundwater table at ~ 2 m below ground. The measured SP values ranged from − 28.4 to 15.4 mV. The SP trend surface, which represents the linear trend in the spatial distribution of SP values, showed that SP values increase with decreasing elevation and in the downstream direction, suggesting a gaining-stream condition. Positive SP anomalies were primarily attributed to streaming potential driven by the hydraulic gradients, whereas negative SP anomalies were associated with redox gradients induced by a biogeobattery system with reducing soil zones. These results suggest that landslide deposits host spatially heterogeneous redox environments. Such environments facilitate the mobilization of redox-sensitive metals such as Mn and Fe, thereby posing risks to downstream hydrochemistry and aquatic ecosystems. To our knowledge, this is the first application of geophysical methods to estimate the spatial patterns of redox conditions within a landslide deposit, providing insights into freshwater resource management and ecosystem functioning in landslide-prone catchments. Integrating geophysical, hydrochemical, and microbiological approaches will enable us to reveal the underexplored environmental impacts of landslide deposits.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"85 9","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12665-026-12961-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829290","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}

An integrated study comprising seismic hazard modeling (along these two prominent active faults), site amplification, empirical vulnerability functions, and geospatial building inventory data in the Delhi-NCT region, has been conducted to propose the possible damage potential ratio, aiding disaster preparedness and risk mitigation. The seismic hazard has been estimated using stochastic finite fault modeling technique, considering moderate earthquake along multiple ruptures along MDF and DSRF, respectively, incorporating the parametric uncertainty.
