The hydraulic dataset is derived from multiple pumping tests at the Hydroscan observatory in Normandy, aiming to map the transmissivity heterogeneity of the gravel aquifer along the Seine riverbanks, which is critical for understanding and optimising hydrological processes. Two distinct inversion methodologies are addressed to decipher the piezometric data: a process-based approach—QLGA—widely recognised for its effectiveness in depicting aquifer hydraulic properties, and a data-driven approach based on Convolutional Neural Networks (CNNs). The QLGA method relies on iterative linearisation with calculations of the Jacobian matrix to minimise an objective function, while the CNN approach directly approximates operators through a novel circular architecture that allows for determining heterogeneity and evaluating its response within a single solver. Results from both methods demonstrate their efficacy in capturing subsurface heterogeneity where the resolution of local details is constrained by the limited number of piezometric measurements. While QLGA achieves a better fit between simulated and observed data, the CNN method effectively handles complex features while reducing smoothing in inversion solutions. When applied to real cases, both methods show strong agreement with observations from synthetic studies, emphasising their accuracy and comparability. The choice between QLGA and deep learning approaches thus depends on problem-specific requirements, data availability, and interpretability needs, providing valuable insights for advanced subsurface characterisation.</p>\u0000 </div>","PeriodicalId":13189,"journal":{"name":"Hydrological Processes","volume":"39 3","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689229","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}

Such projects primarily affect vegetation cover, which in turn influences soil moisture dynamics. This study investigates the changes in surface soil moisture and total soil moisture in the Yellow River Basin before and after the implementation of the Grain for Green Project, thereby assessing its impact on soil moisture conditions. By calculating the trends of soil moisture and NDVI for the periods 1982–1998 and 1999–2014, the effects of the Grain for Green Project on soil moisture were evaluated. We employed partial correlation analysis to obtain the relationship between soil moisture and NDVI. Additionally, an Long Short-Term Memory (LSTM) network model and the SHapley Additive exPlanations (SHAP) values were used to identify the key factors influencing soil moisture. The results indicated that the areas with a significant increase in vegetation are mainly concentrated in the middle reaches of the Yellow River Basin. Moreover, the Grain for Green Project has resulted in a decreasing trend in surface soil moisture and total soil moisture across more than 60% of the Yellow River Basin, with an average reduction of 0.016 m<sup>3</sup>·m<sup>−3</sup>·decade<sup>−1</sup> in the trend of surface soil moisture and 0.021 m<sup>3</sup>·m<sup>−3</sup>·decade<sup>−1</sup> in the trend of total soil moisture.

They vary strongly in response to climatic, hydrologic, and other drivers and are affected by different flow paths. Water residence and travel time distributions carrying information about sources of streamflow can potentially provide a basis for modelling nitrate and TP dynamics. In this study, we use a travel time model coupled with age—concentration relationships to simulate nitrate and TP concentrations in the Duck River catchment, NW Tasmania, Australia. A modified version of the Tran-SAS model was used with time-varying beta storage selection functions, calibrated against high-frequency electrical conductivity (EC) observations. Concentrations of TP and nitrate were then modelled using the water TTDs coupled with age-concentration relationships for TP and nitrate. This approach separated biogeochemical effects from water travel time and ensured consistent TTDs underpinning the transport of different nutrients. Two years (2008 and 2009 water years) of high-frequency nutrient concentrations were used for model calibration and validation. It was initially hypothesised that the age-concentration relationships for nitrate and TP could be temporally fixed, with the seasonal variation in residence time distribution capturing any seasonality in nutrient behaviour. The models performed moderately under this hypothesis; however, residual analysis clearly demonstrated seasonal declines in the concentrations of TP and nitrate during events across the high flow season. Simulations of TP and nitrate were markedly improved by using different source concentrations: one for the early high flow season and the other for the remainder of the year. Both Nash-Sutcliffe Efficiency and the combined seasonal and event dynamics of nitrate and TP were markedly improved by using different source concentrations for these two different periods. This suggests that land management and biogeochemical processing are important influences on the temporal dynamics of nutrients in streams. The study informs future developments of TTD-based water quality modelling and demonstrates the need to include temporally dynamic nutrient source concentrations for young water.</p>","PeriodicalId":13189,"journal":{"name":"Hydrological Processes","volume":"39 3","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/hyp.70104","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638910","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}

These flow pathways can be largely altered through road deformation caused by heavy traffic, with one of the most common types of deformation being ruts. Historically, rut development has been studied using cross-sectional analyses. More recently, remote sensing techniques, such as structure-from-motion (SfM) or terrestrial LiDAR scanning (TLS), have demonstrated their utility in mapping ruts on forest roads. However, applications of these data are limited, especially with respect to flow pathways on the road surface. Here we used SfM, with validation from TLS, to examine the spatially comprehensive development of ruts and their effects on forest road flow pathways and relative sediment transport potential. We carried out a small-scale experiment at two field sites in western Washington using unoccupied aerial vehicles (UAVs) to obtain digital elevation models (DEMs) of mainline logging road surfaces over 3 seasons. These UAV-derived DEMs were used in an elevation change analysis and a simple flow routing model to examine the evolution of ruts and the impacts thereof. We found that: (1) the relationship between measures of rut incision and time since grading was nonlinear at both sites for all seasons with sufficient data; (2) as ruts developed, the flow pathways on the road surface were altered; (3) the relative transport potential of the road surfaces increased overall as ruts developed; and (4) drainage system metrics reveal a threshold rut incision depth for increased transport potential and flow network change. Our results demonstrate that a great deal of useful information can be extracted by using SfM DEMs for the analysis of rut evolution.

As global climate change accelerates, understanding its effects on phenology and WUE is essential for comprehending ecosystem dynamics and carbon–water cycles. Northwest China (NWC), one of the driest regions at similar latitudes, is experiencing a rapid shift from a warm-dry to a warm-wet climate, posing significant challenges to its fragile ecosystem. In this study, we used reanalysis and satellite remote sensing datasets to analyse the changes in the start of the growing season (SOS), the end of the growing season (EOS) and the length of the growing season (LOS) for various vegetation types in the NWC from 1982 to 2015. The focus was on how temperature and precipitation variations influenced phenological dynamics and their subsequent impacts on Gross Primary Productivity (GPP), evapotranspiration (ET) and WUE. Our results show that NWC has experienced a significant warming and wetting trend, with the SOS advancing by 0.04 days per year and the EOS delaying by 0.04 days per year, leading to a notable extension of the LOS by 0.08 days annually. Temperature primarily drives the SOS advance, while precipitation changes in croplands and grasslands and temperature shifts in forests and shrublands dictate the EOS delays. WUE increased at a rate of 0.005 gC m<sup>−2</sup> mm<sup>−1</sup> year<sup>−1</sup>, with temperature and precipitation influencing GPP and ET both directly and indirectly through phenological changes. The findings underscore the cascading effects of warming and wetting on vegetation phenology and WUE in the fragile NWC ecosystem. Changes in the vegetation growing season have had significant impacts on carbon and water fluxes, with varying effects across different vegetation types.

Baseflow typically occurs year-round in perennial streams, though the characteristics and stability of dynamic storage are often most important to instream processes during extended dry periods (without precipitation and snowmelt) when runoff and quickflows are minimised. The term ‘baseflow resilience’ is defined for this review as the tendency of baseflow in streams to maintain a consistent volume and water quality year to year while under stress from climate variability and extremes, along with anthropogenic stressors such as water withdrawals, land use change, and water quality degradation. ‘Baseflow resilience’ has, in part, a user-defined meaning spanning water supply and water quality variables of primary interest. Watershed characteristics that directly impact resilience can often produce non-intuitive feedbacks that enhance some attributes of baseflow while simultaneously impairing others. For example, permeable stream corridor geology creates strong stream-groundwater hydrologic connectivity, yet fast groundwater drainage via preferential high-permeability flowpaths can lead to streamflow not being sustained during extended dry periods. Also, shallow groundwater sources are generally more immediately vulnerable to extreme events, warming, salinization, transpiration, and precipitation drought, compared to deeper groundwater. Yet baseflow drought in streams influenced by deeper groundwater can lag precipitation drought by years, and contaminant legacies may propagate through deep groundwater flowpaths to receiving waters for decades to centuries. Finally, irrigation withdrawals can intercept groundwater that would have drained to streams, and the application of irrigation may leach contaminants from the soil zone by unnaturally raising water tables, yet irrigation return flows can sustain baseflow and groundwater-dependent habitats in semiarid areas. This review covers the concept of hydrologic resilience in the context of stream baseflow processes and summarises the common hydrogeological controls on, and multiscale stressors of, dynamic groundwater storage.

The primary goals of this study were to provide dynamic storage volume estimates, inferred from streamflow recession analysis, for baseflow regimes within seven gaged catchments within the Neversink Reservoir Watershed (NRW), a critical municipal water source for New York City. Additionally, geomorphological properties, surficial geology and hydro-meteorological processes were quantified and described in relation to time and spatially variable recession behaviour and storage estimates across the NRW. To explore these relationships, we (1) evaluated seasonal trends in streamflow recession behaviour in relation to modelled potential evapotranspiration (PET) and catchment runoff rates, (2) derived empirical streamflow models for cool-season runoff using both linear and nonlinear reservoir assumptions for baseflow and (3) calculated metrics related to the geology and geomorphology of each catchment and compared these metrics to area normalised baseflow dynamic storage estimates. Results show that baseflow recession behaves as a nonlinear reservoir, and applying linear groundwater reservoir assumptions may underestimate the total dynamic storage volumes compared to what would be predicted for a nonlinear reservoir. Increases in PET caused decreases in storage conditions that resulted in increased recession rates and nonlinearity in streamflow recession during the growing season. Additionally, we found that while no single physical catchment characteristic solely predicted catchment storage dynamics, sediment volume and stream gradients were stronger predictors of normalised storage volumes than catchment surface area or surface topography alone. Within the NRW, catchments with the highest sediment volume exhibited the lowest recession rates and higher dynamic storage volumes, while the smallest catchment, mostly devoid of sediment, had the fastest recession rate and lowest dynamic storage volume.</p>\u0000 </div>","PeriodicalId":13189,"journal":{"name":"Hydrological Processes","volume":"39 3","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629844","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}
