Abstract Local cubic law (LCL) is one of the most commonly applied physical laws for flow in single fractures (SF) and fractured media. The foundation LCL Darcian flow. This experimental study examines if valid a rough fracture how roughness Reynolds number ( Re ) affect Similar to Moody diagram pipes, has been generated relate friction coefficient with roughness. Under condition this study, appears be substantially different from q ∝ e n J m describing scheme where , are unit width flux,...
Abstract Although numerous studies have been paid much attention to rainfall-induced instability of multilayered slopes, the interface between layers is generally considered be “zero thickness”, and layer transition zone neglected. In this study, influence on slope was investigated. A model developed simulate rainfall infiltration process, distribution pore water pressure, stability by coupling unsaturated seepage analysis method. Based slopes with different thickness ratios zone, a method...
Three-dimensional numerical simulation of subsurface flow dynamics in karst conduits at dam sites represents a pivotal component hydrogeological research, essential for unraveling the intricate behavior water movement within karstified terrains. This study introduces novel approach accounting presence and presents comprehensive three-dimensional site Jingxian Pumped Storage Hydropower Plant. method reduces mesh division, simplifies calculations, improves model convergence. The findings...
Accurate prediction of the contaminant plumes in groundwater systems are critical for effective pollution management and risk assessment. Effective simulations reliable predictions require two key pieces information. The first is detailed knowledge aquifer system, including subsurface structures hydrogeological heterogeneity hydraulic parameters. second data about plume, its source, spatial distribution, concentration. However, acquiring analyzing this often costly labor-intensive due to...
The complex structure of the fractured media and non-Darcy flow may result in non-Fickian lower-than-expected reactant concentrations for reactive solute transport. To explain effects fracture roughness characteristics on transport, a three-dimensional (3D) rough model was constructed, simulations irreversible bimolecular transport under Darcy/non-Darcy conditions were performed. results showed that fluid linear (following Darcy's law) when Reynolds number (Re) approximately less than 10...
The precise prediction of water inflow in tunnels is a key aspect civil engineering. It directly related to the progress construction, stability caverns and safety construction personnel. Currently widely used calculation methods include empirical formula method, analytical method numerical simulation method. In situations where geological conditions are complex boundary irregular, have clear advantages. However, there still discussions about rationality, accuracy applicability definition...
Abstract Fluid flow in single fractures with non‐uniform apertures is an important research subject many disciplines. The abruptly changing aperture a special case of such non‐uniformity. This paper simulates water fracture (SF‐ACA) using the Lattice Boltzmann Method (LBM) and Finite Volume (FVM). occurs Reynolds number ( Re ) ranging from 5 to 900 ratio change E 3 = D/d , where D d are larger smaller apertures, respectively). For values between 100, both LBM FVM can successfully simulate...
Understanding solute transport through macroscopic interfaces is essential to understand the effects of geological heterogeneity on contaminant in porous media. Studies compartmental media have noted asymmetry breakthroughs (BTCs) movement across material interfaces, indicating presence discontinuous concentration that makes directionally dependent. Transition are more common nature than sharp interfaces. To transition well-controlled laboratory experiments were performed. A numerical model...
Understanding solute transport in fractured rocks is of particular importance many applications. Aperture values ranging from 4.7 to 8.7 mm and Reynolds number (Re) at 9.38~1743.8 were set for investigating fluid flow through synthetic horizontal single smooth rough fractures. The Brilliant Blue FCF dye was chosen as the tracer visualize process. This paper focuses on dispersion process fractures under non-Darcian conditions. Non-Darcian existed both average velocity–hydraulic gradient (V–J)...
Ecological problems such as coastal damage and hardening are prominent can be influenced by human activity. It is necessary to carry out ecological restoration tailored specific conditions. To obtain comparable evaluation results for coast level analyze the influencing factors, this study presented an method based on scenarios of sub-parts according structural heterogeneity cross-sections. An empirical nine typical artificial coasts Tianjin, China, determined that under unified assessment...
