While previous studies have investigated the remote influence of atmospheric circulation on the Eurasian climate, the impacts of snow–hydrological processes on near-surface temperature over the snow-sensitive regions have not been fully understood and require further investigation. In the present study, we examined the role of snow–hydrological processes on near-surface temperature variability over the Eurasian continent during the period 1980–2020. Results from Liang–Kleeman information flow analysis revealed that a region of strong snow water equivalent–soil moisture–temperature coupling (called cold spot) is located over the Western Siberia in June, where fluctuations in snow water equivalent and soil moisture tend to modulate near-surface temperature significantly. A composite analysis indicated that a significant decrease (increase) in soil moisture by ∼ 12 % (∼10 %) in response to a decrease (increase) in snow water equivalent by ∼ 6 mm (∼5 mm) during June tends to enhance warm (cold) temperature anomalies over Western Siberia by ∼ 2–3 °C (∼2 °C) through the modulation of surface energy partitioning. In addition, persistent high (low) pressure anomalies, anticyclonic (cyclonic) circulation anomalies, and clear sky (cloudy) conditions associated with the so-called British–Baikal Corridor pattern further favour to maintain the extremely hot (cold) temperature conditions over Western Siberia through land–atmosphere feedback processes.</div></div>","PeriodicalId":362,"journal":{"name":"Journal of Hydrology","volume":"658 ","pages":"Article 133187"},"PeriodicalIF":5.9,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past three decades, China has experienced an extensive vegetation greening trend, raisng great concern about understanding the response of blue water (BW) and green water (GW) resources to vegetation change. To explore this, we employed a process-based distributed hydrological model coupled with a remotely-sensed evapotranspiration module. By conducting hydrological simulations with different vegetation change scenarios for 1982–2012, we observed that the increase in LAI led to a rise in GW by about 1.5 mm year^-1 decade^-1 (0.3 % decade^-1, p &lt; 0.01), close to the decrease in BW [-1.4 mm year^-1 decade^-1 (−0.4 % decade^-1, p &lt; 0.01)]. The enhancement of transpiration was the primary driver of GW increase, while concurrent reductions in soil evaporation partially counteracted these effects, resulting in small overall changes in GW. Strong positive spatial correlations (r = 0.59 ∼ 0.93, p &lt; 0.01) between trend of vegetation-induced changes in the green water coefficient (GWC) and trend in LAI across China suggest that vegetation greening promotes the transition from BW to GW.

Multiple anthropogenic and natural stressors are responsible for driving changes in stream temperatures that can alter ecosystems and degrade water quality. These stressors are variable spatially and temporally, which can be challenging for prioritizing monitoring and research. In this study, an evaluation of variables related to stream temperature was performed for 163 candidate basins of the contiguous United States to highlight potential focal areas. Thirty variables were combined in six components: anthropogenic forcing, natural forcing, climate change, ecological sensitivity, socioeconomic sensitivity, and data availability. The components were incorporated into three themes: vulnerability of streams to thermal change, vulnerability of ecosystems, and vulnerability of communities. By evaluating each theme separately, patterns of vulnerability and potential resiliency were identified as well as consistency in ranks within the themes. For example, results of the national scale ranking indicated the Southern California Coastal basin (within California-Nevada region) was the highest-ranking priority in vulnerability of streams to thermal change and vulnerability of ecosystems. The analysis also identified vulnerable basins with gaps in monitoring. For example, the Missouri-Oahe basin (within the Northern High Plains region) was the highest-ranking priority for vulnerable communities with limitations in data availability. The ranking approach provides insight into basins that are resilient and are ideal candidates for monitoring and research.</div></div>","PeriodicalId":362,"journal":{"name":"Journal of Hydrology","volume":"658 ","pages":"Article 133163"},"PeriodicalIF":5.9,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alluvial fans, significant geomorphological features in hydrogeology, are widely distributed globally, especially in arid and semi-arid regions, and often serve as vital sources of groundwater recharge. This study investigates the hydrological and hydrogeological dynamics of an alluvial fan in the North China Plain, focusing on the impact of the most intense rainfall in 140 years, which delivered a total of 381.1 mm of precipitation in a three-day period. Utilizing field monitoring data, isotopic analysis, and GIS-based modeling, we analyzed runoff generation, groundwater table fluctuations, and groundwater recharge. Results show that the extreme rainfall activated ephemeral river channels, substantially influencing surface runoff. We ultimately identified three different groundwater response patterns: quick responses based on rapid infiltration in the proximity to the mountains, delayed responses based on slow infiltration farther from the mountains, and specific confined aquifer responses characterized by a rapid increase, stabilization, decline, and subsequent gradual increase in groundwater level, possibly influenced by pore-water pressure changes. In addition, we identified stratified groundwater recharge processes based on isotope data and water table fluctuations, with shallow aquifers being rapidly recharged from local precipitation and deeper aquifers receiving slower, lateral recharge from mountainous regions. Our study underscores the important roles of topography and geological stratification in shaping hydrological processes. Further, the findings enhance understanding of groundwater recharge process in alluvial fans in response to extreme precipitation events, providing new insights into sustainable water resource management and flood mitigation strategies.</div></div>","PeriodicalId":362,"journal":{"name":"Journal of Hydrology","volume":"657 ","pages":"Article 133157"},"PeriodicalIF":5.9,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent monitoring in tributaries of the Three Gorges Reservoir (TGR) has identified hypoxic zones, yet the mechanisms underlying hypoxia in these systems remain poorly understood. This study investigates the drivers of hypoxia in the Pengxi River (PXR), a major tributary of the TGR. Field measurements reveal a significant hypoxic zone extending approximately 20 km, with dissolved oxygen concentrations nearing 0 μmol/L. The unique inflow dynamics of the PXR, characterized by warm, slow-moving waters that exacerbate stratification, provide new insights into hypoxia mechanisms in reservoir systems. Further analysis, including the ΔCO₂/ΔO₂ ratio, δ¹³C, and C/N values, indicates that microbial respiration of organic matter—primarily due to algal blooms—is a major contributor to hypoxia in the PXR. The sediment oxygen demand (SOD) was measured at an average of 14.90 ± 4.12 mmol O₂ m⁻² d⁻¹, while the vertical diffusive oxygen flux across the thermocline was 1.59 ± 1.61 mmol O₂ m⁻² d⁻¹, accounting for approximately 10 % of the oxygen consumed by sediments. By quantifying SOD and vertical oxygen flux, this study provides a comprehensive understanding of oxygen dynamics. Furthermore, this study explores potential strategies for mitigating hypoxia through optimizing upstream reservoir management in cascade systems, particularly by adjusting outlet elevations to enhance oxygen supply to the hypolimnion. These strategies offer a scalable approach to alleviating downstream hypoxia.

At the same time, these regions are predominantly underlain by high-grade metamorphic rocks with limited water storage capacity. Widespread chronic kidney disease of unknown etiology (CKDu), which is considered to be influenced by groundwater geochemistry and related factors, is reported in this part of the island. This study, therefore aimed to investigate the geochemical composition and seasonal variations of groundwater in metamorphic aquifers to elucidate possible relationships with the occurrence of CKDu in the dry climatic region. For this study, samples from sixty-six groundwater wells, five surface water sources and one natural spring were analyzed for major anions, cations, trace elements and stable isotopes (δ²H and δ¹⁸O) during pre- and post-monsoon periods. The results showed that the major ions in groundwater mainly derived from the weathering of silicate and carbonate minerals, while seasonal fluctuations significantly influence the geochemical composition. High ionicity in groundwater was found in the pre-monsoon period compared to the post-monsoon. Groundwater isotope compositions confirmed extensive evaporation and possible mixing with surface water during the dry period. Compared to non-CKDu clusters, EC, HCO₃^– and TH were significantly higher in CKDu hotspots, where over 70 % of samples exceeded safe drinking water limits in both sampling seasons. The co-occurrence of significantly high dissolved-Si (mean = 44 mg/L) and F⁻ (mean = 0.90 mg/L) levels in hard water (mean = 340 mg/L) showed the potential risk of their combined effect for CKDu incidence in hotspots. The study showed that groundwater in CKDu hotspots is not suitable for direct consumption due to exceeding geochemical contaminants compared to their standards. Therefore, it is recommended to improve groundwater quality and make it suitable for consumption, possibly through artificial aquifer recharge and water treatment methods. This study highlights the potential groundwater-related risk factors for CKDu in the dry zone, demonstrating that groundwater geochemistry is significantly influenced by seasonal fluctuations and underlying geological characteristics in the region.</div></div>","PeriodicalId":362,"journal":{"name":"Journal of Hydrology","volume":"657 ","pages":"Article 133154"},"PeriodicalIF":5.9,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143696959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
