PhD Student “Interplay between rheology, topography, and deposition in debris flow mechanics” (m/w/d)
Debris and mud flows pose a considerable global hazard, resulting in numerous fatalities and causing substantial damage to infrastructure. These flows consist of a mixture between solid particles of different sizes and a viscous interstitial fluid. Due to their destructive nature, detailed field measurements are difficult. On the other hand, the presence of water renders small-scale flume analyses prone to scale effects. Hence, numerical models can represent very useful tools to bridge the gap between the laboratory and field scales as well as better understand debris flow mechanics and mitigate their impacts.
In this PhD work, you will develop a multi-method and multi-scale framework for the analysis of debris and mud flow mechanics. On the basis of recent work in our group, a SPH-DEM model will be further improved to simulate different solid / fluid mixtures. Calibration and validation of the model will be performed based on existing documented data, and will involve fluid and solid stresses homogenization. In a second step, laboratory experiments will be performed in a new 3D printed flume setting with strong focus on the interplay between rheology and topography, affecting flow mechanisms (e.g., thickness and velocity profiles-evolution along and across the flow, superelevation, overflow and landing upon terrain jumps, deposition patterns) and boundary forces. Particular attention will be devoted to the analysis of the fluid to solid transition (deposition) and the effect of the interstitial fluid on the granular stress (force chains). The SPH-DEM model will be applied to this small-scale complex topographical setting and then upscaled to simulate real documented debris flow events at Mira Bova, GR and Illgraben, WS, in collaboration with Dr. Brian Mc Ardell. Finally, the effectiveness of existing mitigation strategies will be tested and on the basis of the results, some proposals for improved measures will be formulated. You will intensively participate in laboratory and experimental studies (flume and Mira Bova). You will publish your results in high-ranked scientific journals, present them at international conferences and contribute to teaching activities at ETH Zurich.
