Managing volcanic disasters demands swift and accurate information on the behaviour and evolution of lava flows, particularly regarding their extension, displacement, and trajectory. This study addresses numerical and laboratory modelling to understand the dynamics of a lava flow and its frontal advancement. Laboratory experiments of a lava flow analogue, exhibiting a non-Newtonian Herschel–Bulkley fluid behaviour, have been conducted. The fluid parameters at varying temperatures have been determined on the basis of the rheometer and thermal camera measurements. A flow of the Herschel–Bulkley fluid (the lava flow analogue with the fluid parameters determined from the laboratory experiments) is then simulated numerically using the Abaqus software, where a smoothed particle hydrodynamics method has been implemented. A run-out distance, frontal flow displacement, and flow velocity have been determined during laboratory and numerical modelling. When the fluid parameters measured at a constant temperature of 80°C are used, the numerical results diverge from the experimental results over time. To mimic closely the dynamics of the lava flow analogue inferred from the laboratory experiment with its dynamics in the numerical modelling, time-dependent adjustments to the Herschel–Bulkley fluid parameters determined at lower temperatures have been introduced by changing their values during a numerical simulation. This study underscores the importance of constraining parameters of numerical models by the values obtained from laboratory measurements.

TI - Numerical Simulation of Geophysical Models to Detect Mining Tailings' Leachates within Tailing Storage Facilities JF - WATER J2 - WATER-SUI VL - 16 PY - 2024 IS - 5 PG - 18 SN - 2073-4441 DO - 10.3390/w16050753 UR - https://m2.mtmt.hu/api/publication/34908860 ID - 34908860 AB - The effective detection and monitoring of mining tailings' leachates (MTLs) plays a pivotal role in environmental protection and remediation efforts. Electrical resistivity tomography (ERT) is a non-invasive technique widely employed for mapping subsurface contaminant plumes. However, the efficacy of ERT depends on selecting the optimal electrode array for each specific case. This study addresses this challenge by conducting a comprehensive review of published case studies utilizing ERT to characterize mining tailings. Through numerical simulations, we compare the imaging capabilities of commonly used electrode configurations, six ERT arrays, aiming to identify the optimal array for MTLs' detection and monitoring. In addition, field surveys employing ERT were conducted at the El Mochito mine tailings site to detect zones saturated with leachates within the tailing storage facilities (TSFs). The findings indicate that the "Wenner-Schlumberger" array exhibits superior data resolution for MTL detection. However, the choice of the optimal electrode array is contingent on factors such as survey location, geological considerations, research objectives, data processing time and cost, and logistical constraints. This study serves as a practical guide for selecting the most effective electrode array in the context of pollutant penetration from mining tailings, employing the ERT technique. Furthermore, it contributes valuable insights into characterizing zones saturated with mining tailing leachates within the TSFs, providing a solid foundation for informed environmental management and remediation strategies.
