Summary: This study investigates the impact of non-Darcian flow on solute plume distributions within fractures and faults. It reveals that non-Darcian models result in smaller flow line refraction and specific discharge in preferential flow features, leading to larger peak solute concentrations and narrower plumes compared to Darcian models. The study also shows that non-Darcian flow effects are more pronounced with smaller matrix hydraulic conductivity, larger PFF aperture, and larger incidence angle at the matrix-PFF interface.

Summary: This study focused on the non-Darcian flow characteristics of the interlayer shear weakness zone (ISWZ) and its impact on the stability of hydropower station projects. Two analytical methods for studying non-Darcian flow permeability parameters were proposed and validated through in situ tests. The results showed significant differences in equivalent permeability coefficients before and after destruction, suggesting the importance of considering non-Darcian flow when evaluating ISWZ characteristics for engineering stability.

Summary: In this paper, a new semianalytical solution is proposed to investigate the mechanism of transient confined-unconfined flow under the non-Darcian condition in a fully penetrated confined aquifer. The acceptability of the proposed solutions was verified by comparisons with numerical solutions by COMSOL Multiphysics and an analytical solution. The effects of the non-Darcian index, hydraulic conductivity, and the storativity ratio on developments of drawdown and the transient unconfined region were especially investigated. The result offers important insights in the field of mine dewatering and the application of geological and hydrological conditions.

Summary: This study investigated the impact of various geometric and hydraulic parameters on flow behavior and hydraulic conductivity in an artificial fracture. It was found that non-Darcian flow characteristics were observed at different flow rates, and both the Forchheimer and Izbash models were suitable for describing the flow behavior. The study also revealed that hydraulic conductivity was influenced by flow length in fractures with different apertures and surface roughness.

Summary: This article analyzes the convective boundary layer flows of radiating thixotropic nanofluids over a horizontal stretching surface. By considering the retardational influences of Darcy-Forchheimer and Lorentz forces and the contributions of Brownian and thermophoresis diffusions, the study reveals that the thixotropic feature reinforces the nanofluid motion.

Summary: The goal of this research is to improve heat transmission by providing a novel conceptual base for ternary hybridity nanofluids. The ternary hybridity nanofluid, composed of TiO2, Al2O3, and SiO2 nanoparticles suspended in ethylene glycol, offers benefits such as hazardous compound decomposition, environmental cleansing, and equipment cooling. The study examines the thermal and electrical conductivity, specific heat capacitance, viscosity, and density of the ternary hybrid nanofluids. Using the Keller box method, the researchers found that the tri-hybrid nanofluid transferred more heat compared to the hybrid nanofluid, with velocity and temperature field diminishing under specific parameters.

Summary: Compared to single layer porous media, fluid flow through layered porous media with contrasting pore space structures is more complex. This study constructed three-dimensional pore-scale layered porous media and analyzed the influence of interfaces on non-Darcy flow behavior. The results indicate that existing correlations based on single layer porous media fail to accurately predict the flow behavior of layered porous media.

Summary: Motivated by the thermal importance of feeble electrically conducting nanofluids and their flow controls in many industrial and engineering applications, this study comprehensively investigates the electro-magneto-hydrothermal and mass aspects of convective non-homogeneous flows of alumina-based pure water nanofluids Al2O3-H2O over a horizontal flat surface. The study adopts the Buongiorno's approach with the inclusion of Brownian motion and thermophoresis diffusive phenomena, and the numerical results show that the nanofluid temperature is significantly enhanced with porosity factors, nanoparticles' loading, convective heating strength, and thermophoresis process. However, the porosity factors and nanoparticles' loading exhibit a slowing-down impact on the nanofluid motion. Importantly, the nanoparticles' loading and porosity factors contribute to an improvement in the strength of the surface viscous drag forces, while the induced electromagnetic field shows a reverse viscous frictional impact.

Summary: Machine learning algorithms have shown better performance in streamflow prediction compared to traditional hydrological models. In this study, researchers proposed a methodology to test and benchmark ML algorithms using artificial data generated by physically-based hydrological models. They found that deep learning algorithms can correctly identify the relationship between streamflow and rainfall in certain conditions, but fail to outperform traditional prediction methods in other scenarios.

Summary: This study developed a N-cycling model for lowland rural rivers covered by macrophytes and investigated the N imports, exports, and response to sediment dredging. The findings showed a considerable N retention ability in the study river, with significant N imports from connected rivers and surrounding polders. Sediment dredging increased particulate nitrogen resuspension and settling rates, while decreasing ammonia nitrogen release, denitrification, and macrophyte uptake rates.

Summary: High-resolution climate data is crucial for predicting regional climate and water environment changes. In this study, a two-step downscaling method was developed to enhance the spatial resolution of GCM data and improve the accuracy for small basins. The method combined medium-resolution climate data with high-resolution topographic data to capture spatial and temporal details. The downscaled climate data were then used to simulate the impacts of climate change on hydrology and water quality in a small basin. The results demonstrated the effectiveness of the downscaling method for spatially differentiated simulations.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.

Summary: This study investigated the distribution and transformation of dissolved organic nitrogen (DON) in riverbed sediments impacted by effluent discharge. The authors found that the spectral characteristics of dissolved organic matter (DOM) in surface water and sediment porewater could be used to predict DON variations in riverbed sediments. Random forest and extreme gradient boosting machine learning methods were employed to provide accurate predictions of DON content and properties at different depths. These findings have important implications for wastewater discharge management and river health.
