Due to the complexity of the hydraulic-head distribution associated, several practical design issues arise if the exploitation of the resource is to be ensured. Transient and steady-state semi-analytical solutions, based on the method of fundamental solutions, are proposed for evaluating the hydraulic-head distribution caused by a semi-permeable rectangular barrier that fully penetrates an infinite, homogeneous and sloping aquifer, with or without a pumping well. Based on hundreds of simulations with different aquifer, pumping and barrier characteristics, a set of type curves was produced for evaluating <em>i</em>) the duration of equilibrium of the water-table, <em>ii</em>) the length of the barrier to optimize the pumping rate of a given well or its location, and <em>iii</em>) the hydraulic conductivity and width of the barrier. Type curves are used to explain the time-variations in water-table induced by the construction of a railway station basement, and to design a hypothetical underground barrier to raise the water-table level at the location of a pumping well. The variability of barrier characteristics introduced by uncertainty in hydrogeological parameters is also addressed. The analysis of developed solutions includes sensitivity tests and satisfactory comparisons with numerical modelling. Solutions and type-curves can be implemented as operational tools for improving the design of such structures and are meant to supplement existing hydrogeological models.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"205 ","pages":"Article 105091"},"PeriodicalIF":4.2,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144900102","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}

Residual trapping – CO₂ immobilized by capillary forces – contributes significantly to the overall storage. Earlier findings at field conditions have indicated a delayed remobilization – a safety enhancing phenomenon – of residually trapped CO₂ under pressure depletion. The present study investigates the underlying processes of this phenomenon by means of detailed pore-level analysis. We first compare our pore network model predictions against experimental data from high-resolution 3D X-ray imaging. General agreement is found, and in both the experiment and the model, remobilization occurs at a higher saturation value – called the critical saturation (<em>S_gc</em>) – than the residual saturation (<em>S_gr</em>). A significant reduction in the relative permeability of the gas is also predicted. The model is then applied to different rocks. The results show that the <em>S_gc</em> is not a simple function of porosity, permeability or residual saturation. Instead, complex pore scale phenomena related to pore connectivity govern the behavior and case-specific studies are required to determine the exact value. For practical purposes, the difference between residual saturation and critical saturation is approximately between 2–4%. The reduction in gas relative permeability varies between 60–90 % compared to that for drainage with no expansion.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"205 ","pages":"Article 105092"},"PeriodicalIF":4.2,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144900076","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}

Cartesian cell-based anisotropic refinement (CCAR) grids facilitate this process by adaptively refining grid cells in regions of significant heterogeneity or complex flow dynamics. This study proposes a novel mixed hybrid finite element (MHFE) method for solving flow equations on CCAR grids. The method employs hypothetical triangulation, subdividing each CCAR grid element based on the number of surrounding faces. This enables the elimination of internal face unknowns through flux conservation and pressure continuity rules, enhancing computational efficiency without increasing the degrees of freedom. The proposed method was validated using four models, including synthetic and highly heterogeneous domains with various boundary conditions. The accuracy of the proposed method is evaluated against a fine-grid reference solution and a standard finite volume (FV) method applied to uniformly coarsened grids. Across all test cases, the MHFE method demonstrates significantly improved velocity accuracy. Grid convergence analysis revealed consistent monotonic convergence with rates of α  ≈  0.38 for pressure error and α  ≈  0.32 for velocity error. Computational efficiency analysis demonstrated speedup factors of 30–40 x compared to fine-grid simulations while maintaining superior accuracy relative to conventional coarse-grid approaches. Results also demonstrated the ability of the proposed method to accurately compute velocity and pressure fields, as well as streamlines, without distortions or discontinuities, even in complex configurations. By assigning permeability at the hypothetical triangulation level, the method preserved fine-scale heterogeneity and produced a more accurate equivalent permeability field compared to conventional approaches. Additionally, the method imposes no restrictions on the number of neighbors per element, addressing challenges inherent to CCAR grids. These features establish the proposed MHFE method as a robust and efficient tool for advanced upscaling applications in porous media, offering accurate and reliable solutions for complex groundwater systems and geological formations.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"205 ","pages":"Article 105089"},"PeriodicalIF":4.2,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144893003","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}

This study examined how particle density and size influence the distribution of particles in a curved open-channel flow, based on Stereoscopic Particle Image Velocimetry and Discrete Phase Model. Numerical simulations demonstrate that the flow within the bend shows significant mainstream deviation and secondary circulation, which are consistent with the measured results. The research indicates that particle density and size have a significant impact on particle migration trajectories and aggregation in the bend. Particles with low density tend to remain near the central region or upper layers of the flow, whereas those with higher density and larger diameter, owing to their greater inertia and gravitational settling, are more likely to accumulate near the outer bank and bottom layers. The interplay between inertial forces and secondary flow structures gives rise to distinct horizontal and vertical distribution patterns. Considering particle size distribution, particles with larger Stokes numbers tend to concentrate in the outer region of the bend, particularly on the outer side of the 90° ∼ 180° cross-section. These results contribute to a deeper understanding of particle transport behavior in curved channels and offer support for the modeling of particle-laden flows.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"205 ","pages":"Article 105088"},"PeriodicalIF":4.2,"publicationDate":"2025-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896289","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}

The existing physics-informed neural operators struggle with heterogeneous parameter fields due to challenges in automatic differentiation, thus their applicability to parametric learning of subsurface flow remains limited. To address these limitations, FV-PIFNO integrates finite volume method (FVM) discretization of governing equations into the physics-informed loss function, bypassing automatic differentiation (AD) related issues and ensuring flux continuity across heterogeneous domains. A gated Fourier neural operator (Gated-FNO) with space-frequency cooperative filtering is developed to enhance feature extraction and noise suppression. The framework is validated through 2D and 3D heterogeneous reservoir models, demonstrating superior performance in scenarios involving sparse data, variable permeability ratios, and diverse correlation lengths. Results show that FV-PIFNO achieves higher accuracy and robustness compared to data-driven counterparts, particularly under extreme data scarcity. The method’s ability to generalize across untrained parameter spaces and maintain physical consistency in velocity fields highlights its potential as an efficient surrogate model for subsurface heterogeneous flow applications.

In this study, the settling mechanism of sediment from marine outfalls is investigated to quantify its deposition profile through physical experiments, numerical modelling, and dimensional analysis for various source and surface wave conditions. The results show that the sediment undergoes an up-and-down oscillatory motion caused by the orbital motion of water molecules in waves, causing the sediment concentration at the nozzle to vary at different wave phases. Unlike the jet in still water, the wave induces additional turbulence together with the jet flow turbulence which exerts a substantial impact on the average speed of sediment movement, which ultimately determines the pattern of sediment accumulation on the bottom. The sediment turns to settle more slowly under stronger wave momentum intensity (i.e., smaller jet-to-wave velocity ratio <em>R_w</em>). To complement the experimental findings, a 3D Computational Fluid Dynamics (CFD) model was developed using ANSYS Fluent, incorporating a realizable <em>k</em>-<em>ε</em> turbulence model for the fluid phase and a Lagrangian Discrete Phase Model (DPM) for sediment tracking.

The numerical model used OpenFOAM® to solve the Reynolds-averaged Navier-Stokes equations and the stabilized <em>k</em>-<em>ω</em> SST turbulence model, which was adjusted to account for the influence of vegetation. The accuracy of the model was verified using experimental data. Then, the maximum wave run-up height (<em>R</em>_u) and its variations with slopes (<em>m</em>), vegetation density (<em>N</em>_v), vegetation zone length (<em>L</em>_v), and seaward horizontal distance of the vegetation zone (<em>b</em>) under different wave types were analyzed. The results show that the vegetated slopes can significantly reduce wave height along the sloping beach. In most scenarios, vegetated slopes contribute to reducing <em>R</em>_u. Specifically, an increase in <em>N</em>_v generally leads to decreased <em>R</em>_u on the slope, with a maximum reduction of up to 70.3% observed at <em>N</em>_v = 590 elm/m².

The maximum increase in wave run-up height is observed to be 17.9% at <em>L</em>_v = 0.8 m and <em>b</em> = 0.5 m. Changes in slope <em>m</em> and the position of vegetation on the slope effect wave-breaking characteristics, which in turn affect wave run-up. The reduction in <em>R</em>_u is most significant when waves break within the vegetated zone. Finally, a prediction formula for <em>R</em>_u as a function of the surf similarity parameter, wave, and vegetation parameters was developed using the multivariate non-linear regression method.
