In this study, a transboundary, collaborative, physically based groundwater modelling approach has been developed for the Limpopo River Basin (LRB), which is highly vulnerable to floods and droughts. Monitoring data and model results consistently suggest that prolonged wet periods and floods significantly raised groundwater levels, whereas prolonged droughts decreased them, particularly in the upstream and central regions of the basin characterized by low-storage fractured bedrock aquifers. Groundwater-surface water interactions are greater downstream, where water tables are shallower in unconsolidated superficial materials, and intensify during floods, especially in the central region. Modelling results also suggest that baseflow is less responsive to extremes than groundwater recharge across the LRB, highlighting the groundwater system's attenuation capacity. The model was subsequently used to assess and discuss a series of co-created management scenarios focused specifically on improving groundwater storage during wet periods for use during dry periods. They included: (1) managed aquifer recharge (MAR), using (1a) injection well(s) next to large dams, (1b) rainwater and runoff harvesting (RRH) and infiltration through local wells, (1c) RRH through local ponds and (1d) small reservoirs (e.g. sand dams); (2) deforestation; (3) afforestation; and (4) increased groundwater abstraction. Scenarios suggest that strategy (1b), when widely applied across the basin, may be the most effective to reduce the risk and impact of floods, droughts, and groundwater depletion by supporting the maintenance of groundwater levels and baseflow, while reducing storm runoff.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at https://doi.org/10.1007/s10040-026-03143-x.</p>","PeriodicalId":13013,"journal":{"name":"Hydrogeology Journal","volume":"34 6","pages":"1817-1846"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13562358/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148955843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The predominant physicalist ontology of modernity has created such a powerful conceptual representation of groundwater, that seemingly incredible benefits have accrued to society globally via our ability to understand and relate to it in this mode. However, this modern ontological lens goes unnoticed and unannounced in most groundwater research. This study aims to broaden existing narratives about what groundwater was, is and could be, by exploring how groundwater has come to be perceived, understood and defined by WEIRD (Western, educated, industrialised, rich, democratic) societies in which the author is embedded. By considering the co-evolution of four fields of human-groundwater development, namely - behaviour, systems, psychology, and culture - this paper explores how originally participatory ways of perceiving and knowing groundwater gave way to increasingly abstracted propositional modes of knowledge. Eventually many humans came to believe that the abstract symbols and modelled quantities which they used to represent reality were actually reality itself. Thus 'modern groundwater' is now commonly defined and related to as a resource, a 'thing' devoid of inherent meaning or value, separate from ourselves, which can be manipulated to our own ends. Greater epistemic reflectivity, and a pivot to working metaphysically with groundwater as a relational process, may lead to more effective responses to some of the global predicaments we currently face.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at https://doi.org/10.1007/s10040-026-03056-9.</p>","PeriodicalId":13013,"journal":{"name":"Hydrogeology Journal","volume":"34 6","pages":"1679-1699"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13562177/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148955836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on recent work in critical water studies and socio-hydrology, this paper calls for 'situating' socio-hydrogeology by advancing a transdisciplinary understanding of groundwater monitoring practices in the western Indian state of Maharashtra. The paper is based upon a qualitative inquiry into practices of groundwater knowledge production with groundwater officials and farming communities. The paper's findings demonstrate the interplay and integration between scientific practices of groundwater monitoring and alternative, place-based ways of knowing groundwater. It underlines the value of 'being in the field' over technological, distant forms of monitoring that are being mobilised by international, national and regional agencies. It reveals how groundwater officials navigate challenges in everyday practices of monitoring to move 'beyond hydrogeology'-involving decisions made 'off the record' that are shaped by concerns of avoiding bureaucratic burdens. Lastly, groundwater understanding in farming communities is embedded in their cultural and material relationships with groundwater and agriculture, thus offering alternative forms of knowing groundwater.

However, quantifying and identifying their temporally dominating recharge components, as well as delineating their hydrological catchment, can be challenging. The present study makes use of a lumped-parameter rainfall-runoff model (GR4J-CemaNeige) to tackle these issues, applied at a test site in the Ötztal Alps (northern Italy). The model relies on gridded precipitation and air-temperature data and is calibrated using discharge data. Three different catchment scenarios varying in size and glacier coverage extent were modeled to determine the most likely catchment. The model's outcome was validated using oxygen and hydrogen stable isotopes and electrical conductivity analyses. Three dominant recharge components were quantified by the rainfall-runoff model for the 2012-2021 period: snowmelt (607 mm/year, 56%), rainfall (443 mm/year, 42%), and glacial ice melt (25 mm/year, 2%). The rock glacier permafrost ice melt contributes less than 1% of the total annual discharge, falling within the model uncertainty range. The study demonstrates that a simple rainfall-runoff model helps to identify individual recharge components. It gives a crucial indication for the most likely delineation of a rock glacier spring catchment in a complex periglacial and glacial environment. This provides the basis for quantitatively predicting climate change impact on such highly sensitive environments.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10040-025-03005-y.</p>","PeriodicalId":13013,"journal":{"name":"Hydrogeology Journal","volume":"34 3","pages":"687-705"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13083443/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147722559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a workflow was developed to characterise heterogeneous unconsolidated glaciofluvial sediments in Northwest Cumbria (UK), which involved: (1) field sampling; (2) lithofacies classification; (3) in situ porosity measurements using the sand-replacement method; (4) determination of the particle size distribution (PSD); (5) hydrofacies definition via K-means cluster analysis using PSD data; (6) evaluation of empirical equations for predicting porosity using field measurements and regression analysis; and (7) estimation of hydraulic conductivity (<i>K</i>) using the Kozeny-Carman equation. Nine lithofacies were identified, including glaciofluvial silts, sands and gravels, and local till deposits. Three clusters were defined on the basis of PSD: fine-dominated (cluster-1), sand-dominated (cluster-2) and gravel-dominated (cluster-3). Cluster-1 exhibited the highest porosities (average 44%); cluster-2 showed intermediate to high porosities, with an average porosity of 40%; and cluster-3 had the lowest porosities (average 27%).

Measured porosities were higher than previously reported, while estimated <i>K</i> values were consistent with those from hydraulic tests.

A ~100-m-thick Silurian dolostone sequence provides a bedrock aquifer supplying the city of Guelph, Canada. Here, fracture network characteristics and associated influences on hydraulic head were examined using several data types obtained from 24 cored holes in a study that is novel for the quantity and quality of data. High (50–90°) angle joint orientations, heights, and terminations relative to bedding features were determined from acoustic televiewer logs and outcrop scanlines. These data were compared to high-resolution hydraulic head profiles showing head loss over depth-discrete intervals identifying zones with lower vertical hydraulic conductivity. This study reveals that the marl-rich Vinemount Member, traditionally considered the principal aquitard, corresponds to head loss in only 62% of the 24 boreholes. The vertical position of head loss varies across the 90-km² study area and occurs in any of the lithostratigraphic units of the Lockport Group. Within this sedimentary sequence, aquitards are laterally discontinuous or “patchy” at variable depths and relate to: (1) the frequency of the high-angle joints; (2) shorter joint height; and (3) the type of joint terminations. The head loss occurs in thin (2–2.5 m) intervals where the frequency of the high-angle joints is low. Where a large proportion of small joints cross-cut marl bedding planes, head loss is negligible, suggesting that the vertical hydraulic conductivity is not reduced.

Maximum recharge to the central core of the mountain occurs at high elevations, which provides recharge to two overlapping karst aquifers constituting a groundwater storage zone at a lower elevation break in slope. Both karst aquifers are associated with three springs arising from the upper part of the permeable formations. The climate is characterized by long and intense periods of drought and short periods of rainfall, which trigger discharges from the springs. Spring flow recession curve analysis, cross-correlation and monitoring of groundwater temperature and electrical conductivity have demonstrated contrasts observed in the hydrodynamic and physicochemical response of the three springs during flood events. One spring records floods with narrow and short peaks of high discharge accompanied by sharp drops in temperature and electrical conductivity. Another spring records floods with somewhat wider peaks and sharp increases in temperature and electrical conductivity (piston effect), whereas the third spring shows great consistency in all monitored characteristics. It is concluded that the absence of a piston effect in the spring with the highest flow rates is due to the contribution of rapidly circulating water that is expelled by semi-active karst networks (overflow) before reaching the saturated zone, which does not occur in the other springs due to the absence of overflow hydrological pathways. The most regular spring owes its functioning to the contribution of infiltrated water in the bed of an upstream riverbed, which explains this regularity.</p>","PeriodicalId":13013,"journal":{"name":"Hydrogeology Journal","volume":"26 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
