We analysed the runoff sensitivity of 547 watersheds in Great Britain (GB) using data from 2000 to 2015, considering 14 driving factors, including climate, terrain and soils. Using interquartile ranges of daily discharge at annual and seasonal scales, we applied generalised additive models to quantify the influence of each factor. Partial dependence analysis was used to rank driver importance, and perturbation experiments simulated runoff responses under different change levels. Our results reveal strong spatial and temporal variability in runoff sensitivity across GB. Sensitivity is higher in central-east and southwest Scotland as well as southern England. Relative runoff sensitivity, defined as runoff response normalised by precipitation variability, is especially elevated in northwest Scotland and southwest England. On an annual scale, key drivers include evergreen woodland cover, soil saturated hydraulic conductivity and mean daily potential evapotranspiration (PET). In contrast, seasonal sensitivity is shaped by varying combinations of PET, temperature, precipitation, evergreen woodland cover and terrain slope, with precipitation influence differing most across seasons. For relative sensitivity, PET and evergreen woodland are consistently dominant, while temperature, precipitation and soil permeability also contribute seasonally. Perturbation analysis highlights urban, shrub and evergreen woodland cover as having the greatest effects on runoff sensitivity. These findings provide a basis for identifying which land management practices, catchment properties and climate change factors might be most important influencers of riverflow change in different regional settings in GB, thereby supporting evidence-based catchment management and water resources planning under changing environmental conditions.</p>","PeriodicalId":13189,"journal":{"name":"Hydrological Processes","volume":"40 9","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/hyp.70696","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942859","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}

Despite the importance of groundwater flow, its hidden nature makes it difficult to observe and quantify, which results in a poor understanding of its spatiotemporal dynamics from the uplands to the coast. We combine a storage-discharge approach with a long-term (7+ years) water balance to quantify the relationship between catchment storage and stream discharge in 11 (USGS-gaged) watersheds across the Hawaiian Islands. We then use each watershed's storage-discharge relationship to resolve daily estimates of catchment storage and the ‘groundwater leakage’ flux emanating from the watersheds. The resolved mean specific daily leakage is consistent with compiled measurements of submarine groundwater discharge (SGD) at the coast downstream of the 11 watersheds and upland leakage appears to be hydraulically connected to head responses in a basal aquifer. Example groundwater leakage hydrographs from Hālawa (Oʻahu) and Waiākea (Hawaiʻi) watersheds resolve temporal dynamics of groundwater flowing beneath the urban centres of Honolulu and Hilo, where contaminants enter aquifers, threaten drinking water supply, and degrade coastal environments. Although additional data are needed to validate results across space and time, resolving the groundwater leakage flux reveals a previously hidden portion of the hydrologic cycle that can inform modelling of water resources and water quality in leaky watersheds in Hawaiʻi and beyond.</p>\u0000 </div>","PeriodicalId":13189,"journal":{"name":"Hydrological Processes","volume":"40 9","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942974","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}

However, the roles of land use/land cover and soil attributes in shaping post-fire hydrological processes under varying wildfire severities remain insufficiently studied. This study applied the Soil and Water Assessment Tool (SWAT) to characterise and quantify wildfire-induced changes in the water balance across different realistic post-fire scenarios. The Gudgenby River catchment in temperate Australia was selected as the case study area. The following scenarios describe catchment hydrologic conditions: (1) baseline (pre-fire) of 2019–20 wildfires, (2) post-fire Scenario 1 (immediately after the event, March 2020), (3) Scenario 2 (1 year after, March 2021), (4) Scenario 3 (2 years after, March 2022), and (5) Scenario 4 (5 years after, March 2025). The SWAT model was calibrated for the baseline (pre-fire) scenario using observed streamflow to enable detailed sub-catchment-level analysis of post-fire changes. The model performed well, with <i>R</i><sup>2</sup> values of 0.83 and 0.78 for the calibration and validation periods, respectively, with corresponding NSE values of 0.79 and 0.74. Immediately after a wildfire (Scenario 1), surface runoff increased by an average of 34.7% across the sub-catchment. In Scenarios 2 and 3, runoff increased slightly (0.96%), but in Scenario 4, it increased by 1.04% and then decreased relative to Scenario 1 as vegetation began to resprout. Evapotranspiration showed the opposite response: it decreased by 10.3% immediately after the wildfire, then increased by 1.6%, 0.3%, and 0.8% for Scenarios 2, 3, and 4, respectively, as vegetation recovered. Similarly, groundwater recharge declined by 17.7%, 9.1%, and 1.4% in Scenarios 1, 2, and 3, respectively, but increased significantly (22.2%) in Scenario 4, indicating delayed subsurface recovery. These findings offer valuable insights for developing realistic post-fire water management plans and support the design of adaptation strategies and policies for sustainable water management in Australia's temperate zones.</p>","PeriodicalId":13189,"journal":{"name":"Hydrological Processes","volume":"40 9","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/hyp.70676","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942973","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}

Here, we conducted field soil column experiments under natural rainfall using three fracture-filling particle size gradations (C0: 3–5 mm; C1: 6–13 mm; C2: 10–30 mm), coupled with PRA and RSS threshold identification. Medium-sized fractures (C1) achieved the most favourable water retention through a hydraulic conductivity–capillary retention balance: although surface runoff increased relative to C0, the combined runoff and deep leakage loss was lowest in C1 (14.49 mm) versus C0 (16.45 mm) and C2 (16.43 mm). Runoff initiation thresholds consistently ranked C0 &gt; C1 &gt; C2 under both precipitation (124.68, 113.60, 103.27 mm) and antecedent soil moisture (14.79, 10.71, 8.70 mm), with precipitation as the stronger predictor, indicating that coarser fillings lower the activation threshold for preferential flow by enhancing network connectivity. A nitrogen transformation paradox emerged in C1: despite the highest leachate nitrate concentrations (18.34 μg mL<sup>−1</sup>), total nitrogen leaching was ~30% lower than C0, reflecting coupled nitrification–denitrification within its intermediate pore architecture. Runoff thresholds acted as switches for nitrogen loss: leaching increased stepwise only after threshold exceedance, creating nitrogen export hot moments that alternated with safe operating spaces wherein nitrification proceeded without connected leaching pathways. These findings establish fracture-filling particle size as a structural control valve governing water–nitrogen dynamics through threshold-mediated mechanisms, providing a mechanistic foundation for precision water and nitrogen management in karst regions.</p>\u0000 </div>","PeriodicalId":13189,"journal":{"name":"Hydrological Processes","volume":"40 9","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942482","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}

However, because SF<sub>6</sub> concentrations readily equilibrate with the atmosphere upon air contact, the reliability of SF<sub>6</sub>-based age estimates can be strongly influenced by groundwater flow pathways. In this study, we identify groundwater flow systems by exploiting the sensitivity of SF<sub>6</sub> to recharge and flow processes. By integrating SF<sub>6</sub> characteristics with stable oxygen isotopes, we delineate two major groundwater flow pathways in the Matsumoto Basin, a large intermontane basin in central Japan. One pathway involves recharge in mountainous catchments followed by direct subsurface flow into the basin aquifer and is characterised by older, chemically evolved groundwater influenced by cation exchange and reducing conditions. The other involves recharge within the basin lowlands by surface water derived from the mountains and is characterised by relatively young, oxygenated groundwater associated with carbonate and sulphate mineral dissolution. Intermediate hydrochemical signatures indicate hydraulic connectivity and mixing between these flow systems, reflecting differences in groundwater residence time, flow dynamics and water–rock interaction histories. These pathways are supported by elevated SF<sub>6</sub> concentrations exceeding atmospheric equilibrium and by the behaviour of fluoride and lithium ions, indicating anthropogenic influences at the land surface. The systematic relationships among hydrochemical parameters, stable isotopes and environmental tracers demonstrate that the contrasting signatures primarily reflect distinct groundwater flow regimes and their mixing processes. Identifying these dominant pathways is critical for developing effective recharge strategies to mitigate long-term groundwater-level declines in the Matsumoto Basin. More broadly, recognition of such flow-path structures is fundamental for designing sustainable recharge practices and supporting water-resource management and environmental protection in intermontane basins with similar geographic, geological and climatic settings.</p>\u0000 </div>","PeriodicalId":13189,"journal":{"name":"Hydrological Processes","volume":"40 9","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942366","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}

Using multi-decadal observations from 18 streamflow gauging stations and four meteorological stations, we analyse basin behaviour through (i) Budyko and Fu curves fitting, (ii) detection of regime shifts using time-series segmentation and (iii) attribution of streamflow changes via both decomposition and sensitivity methods. A common hydrological regime shift was detected in 1984, after which streamflow consistently declines across most streamflow gauges. Post-change periods exhibit elevated Fu parameters and increased evaporation ratios, indicating reduced runoff and intensified aridity. A high majority of gauging stations align closely with Budyko expectations, while deviations—particularly in high-altitude headwaters—are attributed to karst geomorphology, snowmelt processes and data limitations. Attribution analysis reveals that climate variability, especially declining precipitation, accounts for 50%–75% of the total streamflow change, though local anthropogenic drivers also contribute significantly in specific sub-basins. These findings mirror regional hydroclimatic patterns across the Mediterranean Basin and reinforce the Gediz River Basin's sensitivity to both climate stress and water management practices. The well-established knowledge that humans are the main factor creating the streamflow decrease has been softened with our data-limited results showing that the climate-driven change in Western part of Turkey could be higher than the human effect. The study is a detailed basin-scale understanding, rather than implying a methodological breakthrough or a definitive proof of persistent Budyko conformance. It emphasises that the hydrological character of Gediz River Basin provides an opportunity to develop Budyko-based practical methodologies for the river basin-scale water resources planning and management strategies that could potentially be transferable to data-scarce, semi-arid regions facing escalating water insecurity.</p>","PeriodicalId":13189,"journal":{"name":"Hydrological Processes","volume":"40 9","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/hyp.70657","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942153","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}
