Analogue modelling of pyroclastic density current deposition
2010A series of analogue flume experiments are used to investigate initiation, flow and deposition of static piles of polymict materials, the sorting during transport, and the three dimensional geometry of the resulting deposits. Sequential charges are used to investigate the effects and extent of reworking.

Multiphase flow dynamics of stratified pyroclastic density currents
2013We have simulated the dynamics of pyroclastic density currents to quantify the influence of the vertical stratification of particle concentration on their propagation and runout. The polydisperse pyroclastic mixture is described by discretizing the grain-size distribution into N particle classes and by adopting a non-equilibrium Eulerian transport ...
