This has been extensively investigated at the mesoscale or field scale. However, at a small scale (centimetres), the nonequilibrium partitioning can also be triggered by varying the local Péclet number even in homogeneous porous media. The effects of the nonequilibrium partitioning, induced by changes in the Péclet number, on moment and model-based analyses of breakthrough curve data are not yet fully understood. This study employs pore- and continuum-scale numerical simulations to investigate the nonequilibrium partitioning and transport of partitioning tracers at various Péclet numbers, residual saturations, and partitioning coefficients. The results suggest that the moment analysis is more accurate for the tests at small Péclet numbers, large distances between the injection and measurement locations, and small residual saturations. The characteristics of the breakthrough curves for the partitioning tracer strongly depend on the Péclet number. In non-equilibrium conditions, early concentration peaks, representing the fraction of the tracer that travels only in the aqueous phase, are observed. Moreover, the continuum-scale model-based analysis performs well for low partitioning coefficient conditions, with the partitioning mass transfer coefficient being linearly correlated to the Péclet number. In contrast, for high partitioning coefficients, the models are only matched by applying an effective partitioning coefficient, which depends on the residual saturation, the Péclet number, and the actual partitioning coefficient.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"206 ","pages":"Article 105142"},"PeriodicalIF":4.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145324348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies on optimizing groundwater contaminant remediation systems (GCRSs) have not adequately accounted for these multi-source uncertainties, thereby compromising the reliability of remediation schemes and increasing the risk of remediation failure. In this study, a novel Bayesian model averaging-probabilistic multi-objective simulation-optimization (BMA-PMOSO) model is developed to optimally design GCRSs under multi-source uncertainties. In the new model, the BMA theory is employed to calculate the mean and variance values of objective functions. The Arithmetic Mean Estimator (AME) method is used to determine the marginal likelihoods of each conceptual models and subsequently calculate their posterior weights. The Differential Evolution Adaptive Metropolis (DREAM) algorithm is applied to analyze the parameter uncertainty for each conceptual model, thereby obtaining the posterior distribution of parameters. The PMOFHS-GA is adopted to identify Pareto solutions. Furthermore, a new final decision-making strategy, the objective reliability based improved decision strategy (OR-IDS), is developed to assist decision-makers in selecting the final best remediation scheme. The proposed model is applied to a 2-dimensional synthetic problem and a 3-dimensional field problem. Results demonstrate that uncertainties in both model structure and parameters will cause significant impacts on optimization results. The BMA-PMOSO model can effectively optimize GCRSs under complex uncertainties, offering decision-makers highly reliable remediation schemes.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"206 ","pages":"Article 105153"},"PeriodicalIF":4.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145462596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fernández-Nieto ,&nbsp;Jose Garres-Díaz ,&nbsp;Jorge Moya","doi":"10.1016/j.advwatres.2025.105178","DOIUrl":"10.1016/j.advwatres.2025.105178","url":null,"abstract":"<div><div>The Saint-Venant–Exner (SVE) model is widely used for the description of sediment transport including bedload, erosion, and deposition processes. A modified version of the SVE model, which includes sediment concentration, incorporates exchange of sediment between the fluid and an erodible bed and a non-hydrostatic pressure for the fluid along with non-equilibrium entrainment and deposition velocities, is introduced. Gravitational effects on erosion are described by an effective shear stress formulation. This modified SVE model is derived from a general approach with density variations. It preserves the mass of both the sediment and the fluid, and satisfies a dissipative energy balance. On the other hand, well-balanced finite volume schemes adapted for SVE models are derived since standard well-balanced schemes for the Saint-Venant system with fixed bottom are in general no more well-balanced when applied to the SVE model. The latter property is due to the uncontrolled numerical diffusion associated with the bed evolution equation. Two novel techniques to achieve the well-balanced property for the modified SVE model are proposed. The first is a new polynomial-viscosity-matrix-based (PVM) scheme, denoted “PVM-2I”, that modifies the numerical approximation of the bed evolution equation according to its related characteristic speed. The second is a physically motivated correction of the numerical diffusion term for the Rusanov and Harten–Lax–van Leer (HLL) schemes. The proposed schemes are positivity-preserving for the water height. Numerical solutions are compared with exact solutions with gravitational effects, with a novel exact solution in non-equilibrium conditions, and with experimental data. It is illustrated how the use of standard non-well-balanced schemes leads to a large artificial (unphysical) erosion and completely degraded solutions. This undesirable behaviour is avoided by the proposed well-balanced schemes. Moreover, it is demonstrated that for dam-break flows the inclusion of non-hydrostatic pressure improves the prediction of the water surface and sediment evolution, while for overtopping flow erosion tests, accounting for erosion–deposition exchanges between the bedload and suspended sediment layers leads to better agreement with experimental data.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"206 ","pages":"Article 105178"},"PeriodicalIF":4.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145598733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a computational example, we train a deep convolutional neural network (CNN) to reconstruct permeability fields from saturation maps derived from a multiphase flow model.

Quantifying the fluctuations in soil moisture in response to variations in rainfall events is crucial for understanding the effects of climate change on regional water availability. Therefore, the purpose of this article is to generalize the previous results presented in the literature on quantifying temporal variability of soil moisture, which only apply to temporal stationarity in the random rainfall perturbation field. In this article, a general solution for the theoretical soil moisture semivariogram is derived to quantify the temporal variability of the nonstationary soil moisture perturbation field driven by the temporal nonstationary rainfall perturbation field. The use of the Fourier-Stieltjes spectral representation and the representation theorem enables the development of the theoretical soil moisture semivariogram expressed in the Fourier frequency domain. In addition, an approximate solution of the soil moisture semivariogram is given for the case that the temporal fluctuations in the rainfall field can be characterized by long-range power-law correlations.
