Beaver dam analogs (BDAs) offer a process‐based alternative to conventional gray or hard‐engineered stormwater infrastructure to slow flow, promote sediment deposition, and enhance channel‐floodplain connectivity, but their hydrologic and geomorphic performance in stormwater‐driven, mixed land use watersheds is not well understood. This study describes the geomorphic and hydrologic responses 1 year after installing eight BDAs in an ephemeral, stormwater‐driven stream within a mixed‐land use watershed (68% agricultural, 28% developed, 4% forested) in Selinsgrove, Pennsylvania. Water‐level loggers showed significantly longer retention time in upstream BDA pools than downstream pools ( p < 0.01), suggesting that BDAs moderate flow during storm events along the downstream gradient. Cross‐sectional surveys showed net sediment deposition in upstream BDAs 1–5 and net erosion at BDAs 6–8, with the most upstream BDAs accumulating up to 10–20 cm of vertical sediment. Substrate analyses revealed a shift from coarse to finer materials, with median grain size declining from 27 to 14 mm ( p < 0.0001) and fine earth content (<2 mm) increasing by 6.7% post‐installation ( p < 0.05), consistent with reduced stream energy and enhanced deposition upstream of BDAs. Together, these results document how BDAs alter hydrologic retention and sediment transport in a flashy, human‐impacted stream, suggesting that process‐based restoration responses commonly reported in perennial systems can also emerge under episodic, storm‐driven flow conditions.","PeriodicalId":23799,"journal":{"name":"Water Resources Research","volume":"81 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148932560","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}

Accurate mapping of GDEs is essential for improving water resource management and ecosystem conservation. The distribution of GDEs remains largely unknown across contiguous China. In this study, remote sensing data, soil data, and modeled groundwater depth (GWD) data are integrated to map GDEs across both arid and humid regions of contiguous China. The mapping framework utilizes long‐term remote sensing data combined with drought‐related climatic data to characterize vegetation responses under selected hydroclimatic conditions. These conditions are selected to highlight the differences in vegetation responses between GDEs and non‐GDEs. By integrating vegetation temporal dynamics with hydroclimatic indicators, this approach enables systematic mapping of GDEs. The results indicate that high‐, moderate‐, and low‐potential GDEs account for 1.6%, 7.7%, and 22.1% of the mapped area, respectively. Assuming a vegetation rooting depth within 10 m, the GDE map shows a commission error of 13.6% against observed GWD. The reliability of the GDE map is further supported by vegetation responses to drought and the characteristic topographic settings of GDEs.","PeriodicalId":23799,"journal":{"name":"Water Resources Research","volume":"6 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148932880","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}

We enhanced the PFLOTRAN model by developing an ET module and validated it against HYDRUS simulations. Using the calibrated model, we analyzed tile drainage effects on hydrological dynamics at an Iowa corn site during a critical vegetative‐stage period and assessed the influence of tile depth and spacing. Simulations showed that tile drainage produced distinct spatiotemporal soil moisture patterns, with topsoil moisture aligned with the pipe layout. Compared to an undrained scenario, the tile drainage system at the experimental site increased ET by approximately 16% and significantly altered surface–subsurface water partitioning. Design experiments further showed that compared to the baseline depth (1.2 m), shallower drains (0.76 m) reduced tile flow by about 78%, decreased ET by approximately 10%, and substantially increased surface runoff. In contrast, tile spacing has a limited impact on ET (<2%) across the tested range (10.8–27 m) and exerts a secondary influence relative to tile depth, with consistently smaller variations across other water budget components. Using these findings, we proposed a framework to evaluate drainage design using ET deficit (Potential ET–ET) and economic cost, identifying 1.2 m depth and ≥18 m spacing as optimal at the study site. These findings contribute to a site‐adaptable digital twin framework for tile drainage design, offering a tool to optimize water management.","PeriodicalId":23799,"journal":{"name":"Water Resources Research","volume":"171 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893698","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}

Thus, rainforest loss in these areas can reduce evaporation as well as subsequent rainfall in the wider forested region. During dry periods, a dampened water cycle may potentially aggravate rainforest water stress. However, few studies have investigated dry‐period moisture recycling statistics within rainforests over longer records and consistently compared the rainforest moisture recycling in both continents. Here, we analyze dry‐season anomalies of moisture recycling for mean‐years and dry‐years, in the South‐American (Amazon) and African (Congo) rainforests over the years 1980–2023. We find that dry‐season rainfall reliance on rainforest moisture increases slightly, but statistically significantly, by 5% (from a mean annual of 21% to 22%) in the Amazon and up to 12% (from 24% to 27%) in the Congo. At the same time, a lower fraction of rainforest evaporation stays within the rainforest during the dry season: 21% less from the Amazon (from 41% to 32%) and 22% less from the Congo rainforest (from 32% to 25%), which further decreases with increasing dryness. In response, areas downwind of the rainforests gain a higher dependency on rainforest moisture during dry seasons, amplified during dry years. For example, rainforest‐sourced rainfall in Ecuador increases from annually to in the dry season. The findings highlight the critical role of rainforests in maintaining rainfall during periods when water is already scarce.","PeriodicalId":23799,"journal":{"name":"Water Resources Research","volume":"137 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893697","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}

Under prolonged drought, dominant shrubs self‐organize into two typical spatial configurations: scattered with separated individuals and clumped with clustered individuals. How the coordination between root water uptake and leaf physiological traits drives water use strategies of self‐organized shrubs for adapting to drought remains poorly understood. To address this gap, soil moisture, morphological and root traits, leaf‐level physiological traits, and stable isotope ( δ 2 H, δ 18 O, and δ 13 C) of scattered and clumped Vitex negundo were observed during 2022–2024 in the semi‐arid Loess Plateau. The scattered shrubs primarily utilized middle and deep soil water (62.3 ± 7.8%), associated with isolated canopies that promote infiltration into deep soil layers. In contrast, clumped shrubs relied on shallow and middle soil water (82.0 ± 6.5%), linked to aggregated canopies and shallow roots. Scattered shrubs showed tight stomatal regulation with high midday leaf water potential and intrinsic water use efficiency (iWUE) during dry season, whereas clumped shrubs exhibited relaxed stomatal regulation, with declines in midday leaf water potential and iWUE. In rainy season, scattered shrubs constrained gas exchange, while clumped shrubs enhanced stomatal conductance and photosynthesis. These findings indicate that scattered shrubs adopt an active deep‐water acquisition with conservative water utilization strategy, enhancing drought resistance, while clumped shrubs exhibit an opportunistic shallow‐water acquisition with acquisitive water utilization strategy, improving water capture efficiency for drought adaptation. This study reveals the ecohydrological processes of self‐organized vegetation in drylands and provides basis for vegetation allocation in ecological restoration.","PeriodicalId":23799,"journal":{"name":"Water Resources Research","volume":"48 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148932603","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}

GNSS‐Reflectometry (GNSS‐R), which exploits reflected satellite navigation signals, has emerged as a rapidly growing alternative for soil moisture retrieval, increasingly positioned as a low‐cost path to global observation. The two approaches, however, differ fundamentally in how they sense the surface, and the hydrological science community should weigh these differences carefully before decisions are made that could compromise the continuity of this essential climate variable's data record. In this study, we compared soil moisture products from these two systems across seven perspectives: (a) observation characteristics, (b) spatial resolution, (c) coverage and frequency of observations, (d) vulnerability to radio frequency interference, (e) complementarity potential, (f) performance, and (g) cost considerations. Our assessment suggests that GNSS‐R is better understood as a complement to SMAP than as a replacement. A GNSS‐R constellation can deliver sub‐daily observations, and lower upfront costs, capabilities that genuinely extend what single‐platform missions can offer. At the same time, GNSS‐R retrievals exhibit variable spatial sampling and canopy attenuation, and the highest‐performing products are typically trained, calibrated, or benchmarked against SMAP (an implicit cost that the low‐cost framing of GNSS‐R does not fully capture). Taken together, these findings underscore the need for sustained investment in both SMAP‐class L‐band missions and the expanding GNSS‐R constellation, each contributing complementarity strengths to a resilient global soil moisture observing system.","PeriodicalId":23799,"journal":{"name":"Water Resources Research","volume":"36 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148932604","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}

This study presents a framework to investigate how the number and location of observation depths used in calibration influence temperature prediction accuracy and parameter equifinality. We leverage a computationally efficient one‐dimensional physics‐based model (GLM; General Lake Model), and apply probabilistic parameter estimation within a Generalized Likelihood Uncertainty Estimation framework. Using 7 years of hourly water temperature data from Lake Mendota (WI, USA), we quantify parameter equifinality and assess predictive performance using multiple metrics across single‐depth, dual‐depth, and full‐profile observation. Results show that single‐depth deep‐water observations consistently outperform shallower depths and sometimes even full‐profile observations, significantly reducing equifinality and achieving accurate match throughout the water column. Contrary to expectations, full‐profile data do not consistently yield superior predictive performance across the water column. Instead, they dilute the influence of deep‐water observations on parameter selection. Dual‐depth scenarios show that single‐depth surface mixed layer observations can be vastly improved by adding a second observation depth. These findings provide practical examples for optimizing observational strategies and advancing lake hydrodynamic modeling. In particular, this work supports the management of drinking water reservoirs by informing the strategic selection of fewer, well‐placed deep‐water observations. In doing so, it focuses model development toward critical depths—for example, for drinking water reservoirs that commonly rely on deep‐layer intakes.","PeriodicalId":23799,"journal":{"name":"Water Resources Research","volume":"141 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148932605","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}

Many vastly underestimate snow water storage, and guidelines regarding which products are more accurate are crucial for using these products in any scientific analysis. Here, we review existing products and compare them to each other and to SWE derived from 26 aerial LiDAR acquisitions in Colorado, California, and Washington mountains of the western U.S. Products that match well with observations include (a) resolution of 9 km or finer, (b) reliance on observations of either fractional snow‐covered area or in situ SWE measurements, and (c) a well‐calibrated model framework that includes both quality precipitation estimates and accurate snowmelt. Many of the energy balance models reviewed had too much melt, likely from too much incoming radiation. Over all three regions, for the 14 flights that occurred close to peak SWE (March–April), the Western U.S. SWE Reanalysis (WUS‐SR) is least biased in reproducing near‐peak SWE (bias of 1.6%) and also best represented the spatial distribution of SWE (smallest mean absolute error).

A deeper understanding of these micro‐scale dissolution mechanisms is therefore essential for the safety of geological CO 2 sequestration. To address this challenge, we develop a multi‐field coupled simulation framework that integrates the Lattice Boltzmann Method (LBM) with the Finite‐Discrete Element Method (FDEM) to model solute transport and mineral micro‐structure dissolution. The framework incorporates a geometric mapping detection scheme and an improved momentum exchange algorithm to capture fluid‐solid interactions. Furthermore, a novel updating scheme for dissolution rates and solute concentrations is proposed, explicitly accounting for mass conservation and complex mineral morphology. A dynamic geometric topology updating algorithm is also proposed to track the morphological evolution of mineral grains. The accuracy and capability of the LBM‐FDEM framework are validated through several numerical benchmarks, including particle settling, solute release from a moving particle, dissolution of polymorphic particles, and reactive transport within a non‐uniform channel, yielding excellent agreement with existing solutions. Finally, this proposed method is applied to investigate the spatiotemporal evolution of fracture dissolution under varying Péclet numbers. The numerical results reveal that under diffusion‐dominated low Péclet regimes, product accumulation restricts dissolution to the upstream inlet, yielding a typical face dissolution pattern. Conversely, strong advection under high Péclet conditions drives rapid reactant penetration, triggering a uniform channelized widening along the entire fracture. Ultimately, this framework demonstrates significant potential for investigating complex hydro‐mechanical‐chemical couplings in subsurface engineering.","PeriodicalId":23799,"journal":{"name":"Water Resources Research","volume":"53 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2026-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893647","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}
