In this paper, the lattice Boltzmann method (LBM) and discrete element (DEM) are coupled to simulate interaction between fluid phase irregularly shaped solid particles. For purpose, geometry of realistic particle shapes is represented as clumps overlapping spheres then simulated through a multi-sphere model in DEM with LBM using two open-access codes, LIGGGHTS Palabos. The accuracy coupling demonstrated by simulating several benchmark cases comparing them results from literature. LBM-DEM used collapse transport submerged granular particles spherical shape irregular shape, respectively, highlight influence grain morphology solid–fluid interaction. Compared previous for highly idealized non-spherical shapes, research provides more computational framework capture complex geomaterials clumps/multi-spheres, which useful studying underlying effect on geotechnical issues such internal erosions.

Investigating the failure mechanisms of cascade landslide dams under overtopping conditions: an experimental approach

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Фев. 18, 2025

Under strong earthquakes and extreme rainfall conditions, landslide clusters near rivers may block incoming water flows, forming cascade dams. When subjected to hydrological these dams can experience overtopping, which erodes entrains material from the dam surface, compromising stability, potentially lead outburst flooding. Although existing research provides valuable insights into failures, it falls short in addressing complexities of cascading failures groups. The influence various factors on this intricate process is still only partially understood, highlighting need for a comprehensive understanding surface evolution flood flow dynamics specifically within context In study, we conduct physical model experiments categorize stages failure, identify typical failure modes, investigate mechanisms affecting breach morphology development during failures. Our findings reveal that amplify floods breaches, with peak rates increasing progressively upstream downstream. systems, downstream accelerated processes, where layer erosion becomes predominant. Significant fluctuations river levels between cascades slope both Specifically, exhibit more rapid widening, fewer instances collapse at compared dams, earlier timing, making breaches challenging emergency response. These observations highlight notable differences single Based findings, provide developing mathematical models improve physical-based predictions, will assist early warning strategies floods.
