Applied to 94 snow-dominant watersheds from the CAMELS dataset over a 30-year period, our approach first implements a multivariate calibration strategy that optimizes Snow-17 model parameters using observed snow water equivalent (SWE) and SACSMA model parameters using observed streamflow. This calibration strategy improved SWE prediction while maintaining streamflow performance. Following this calibration, we implemented a multivariate data assimilation using the Evolutionary Particle Filter with Markov Chain Monte Carlo (EPFM) algorithm. This system simultaneously integrates both SWE and streamflow observations with the models, enhancing prediction accuracy according to multiple performance measure. The framework demonstrates exceptional seasonal performance, with peak SWE prediction skill in winter and improved accuracy in predicting peak flow during spring snowmelt. Over 90 % of the basins showed improved peak flow prediction, critical for water resources planning and management. A comprehensive assessment across diverse geographic regions, hydroclimatic conditions, and multiple metrics confirms the framework's robustness and versatility.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"207 ","pages":"Article 105192"},"PeriodicalIF":4.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145689886","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 employs a synergistic approach, combining Particle Image Velocimetry (PIV) with numerical modeling to quantitatively link interlayer attributes to disturbances in the brine flow field. The effects of interlayer collapse on brine flow field dynamics, including range, thickness, number, spacing, and tubing position, are systematically analyzed. The results indicate that the interlayer collapse range, rather than its thickness, is the dominant control on flow segmentation. For a single interlayer, a high overhanging degree (<em>η</em> &gt; 0.4) combined with positioning the tubing string above the interlayer results in severe partitioning of the flow field, confining over 80% of the convective energy to the lower cavern. This partitioning effect is significantly mitigated when the tubing is placed below the interlayer or when the overhanging ratio is reduced below a critical threshold of 0.3. Furthermore, we demonstrate that multi-interlayer structures correct the primary flow deviation but induce localized, high-vorticity recirculation zones between layers, explaining the formation of wall irregularities. Mechanistically, we identified a dual-scale erosion process: a global turbulent flow drives bulk dissolution, while localized deflected jets sculpt the deep cavities. These findings provide critical theoretical guidance for optimizing the construction and ensuring the morphological stability of salt caverns in complex, bedded salt formations.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"207 ","pages":"Article 105183"},"PeriodicalIF":4.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145657973","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}

These interactions are modulated by the spatial distribution and density of the vegetation. We conducted idealised numerical simulations using a depth-averaged hydrodynamic model to explore how circular gaps (of diameters 0.4 to 9 m) within otherwise continuous beds of emergent aquatic vegetation alter in-canopy horizontal flow patterns. Our findings indicate that gaps reroute and concentrate horizontal flow, creating areas of accelerated flows within the canopy. As gap size increases, horizontal flow speeds also increase, though the rate of increase diminishes substantially for gap diameters larger than 5 m. In cases with paired gaps, two distinct interaction modes were identified, one occurring when the gaps were aligned with the flow, leading to mutually reinforced flow intensification within the gaps, and another when they were positioned side by side, resulting in diminished flow acceleration associated with each bare gap. The maximum flow change within the canopy occurred at streamwise gap separations of three gap diameters, with minimal changes for gap separations of greater than four diameters. The increase in horizontal flow speeds was directly proportional to the percentage of bare bed cover. For a given percentage of bare bed cover ranging from 8 to 40 %, flow changes were also modulated by the fragmentation level, which is determined by the number and size of gaps. The results reveal that fragmentation levels control in-canopy flow speeds, whereby fewer, larger gaps exerted a more pronounced impact on in-canopy horizontal flow speeds compared to numerous smaller gaps. The interconnected nature of vegetation coverage and gap distribution underscores the role of fragmentation levels in ecohydrological dynamics.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"207 ","pages":"Article 105182"},"PeriodicalIF":4.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145611783","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 dam has a vertical cutoff wall, placed at an arbitrary distance between the head water and tail water. Evaporation from the reservoir horizontal water surface, as well as pumping (or injection) are contributing to the mass balance in the head water that gives an ODE, which is solved either exactly (if no pumping or a constant rate pumping that gives either a linear or the Abel ODE, solved two centuries ago), or by a computer algebra routine of numerical integration (as the Cauchy problem with a “time front” indicating a complete depletion of the reservoir).

Results show that waves alter the hydraulic gradient to modify groundwater flow and drive water circulation in the lakeshore zone. Waves enhance water exchange between the lake and inland, while suppressing the net discharge of groundwater into the lake. Waves also alter subsurface solute pathways, shifting discharge zones toward the lake and increasing solute travel time. Sensitivity analysis reveals that the circulation zone extent and the lacustrine groundwater discharge rate are sensitive to wave height, wave period and inland groundwater level. Larger waves expand circulation areas and increase lacustrine groundwater discharge, whereas higher inland groundwater levels reduce circulation zones.

To address these limitations, the enriched-embedded discrete fracture model (nEDFM) is proposed. The core idea of nEDFM lies in defining the local shape function that approximates the pressure distribution within the interaction region (IR). This function can capture discontinuities in pressure and its gradient across both conductive and blocking fractures and is applicable to media with isotropic or anisotropic matrix permeability. Nonetheless, the original local shape function is limited to cases with at most one fracture in the IR and cannot represent the complex discontinuous pressure fields arising from multiple intersecting fractures. This paper extends nEDFM to fracture intersection scenarios through two key innovations: 1) based on two modification criteria for local shape functions under multiple-fracture configurations, enriched degrees of freedom are reallocated to intersecting fracture cells, and corresponding discontinuous functions are designed to construct new local shape functions that can handle arbitrary intersections of conductive/blocking fractures; 2) to address the inaccuracy of the star-delta transformation in computing flow interaction between fractures with large permeability contrast, the permeability of the intersection area between conductive/blocking fractures is incorporated to establish an improved star-delta formulation. Four numerical cases involving intersecting or closely spaced fractures are conducted to evaluate the relative error and computational cost of nEDFM in comparison with EDFM, projected EDFM, and other non-conforming grid-based methods. The results show that nEDFM can accurately capture the pressure distribution within both conductive and blocking fractures, and effectively represent discontinuities when these fractures intersect or are in close proximity. Overall, nEDFM achieves an excellent balance among accuracy, computational efficiency, and general applicability, demonstrating strong potential for further development and practical implementation.</div></div>","PeriodicalId":7614,"journal":{"name":"Advances in Water Resources","volume":"207 ","pages":"Article 105198"},"PeriodicalIF":4.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145785703","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 is supported by our observation of periodic pressure fluctuations associated with intermittent fluid connectivity for hydrogen and methane. In conclusion, our findings suggest that the fundamental flow properties of fractured rocks are complex but relatively similar for hydrogen and natural gas.
