Journal Article
Smith, G., Rowley, P., Williams, R., Giordano, G., Trolese, M., Silleni, A., …Capon, S. (2020). A bedform phase diagram for dense granular currents. Nature communications, 11(1), Article 2873. https://doi.org/10.1038/s41467-020-16657-z

Pyroclastic density currents (PDCs) are a life-threatening volcanic hazard. Our understanding and hazard assessments of these flows rely on interpretations of their deposits. The occurrence of stratified layers, cross-stratification, and bedforms in... Read More about A bedform phase diagram for dense granular currents.

Investigation of variable aeration of monodisperse mixtures: implications for pyroclastic density currents (2018)
Journal Article
Smith, G. M., Williams, R., Rowley, P., & Parsons, D. R. (2018). Investigation of variable aeration of monodisperse mixtures: implications for pyroclastic density currents. Bulletin of volcanology, 80(8), Article 67. https://doi.org/10.1007/s00445-018-1241-1

The high mobility of dense pyroclastic density currents (PDCs) is commonly attributed to high gas pore pressures. However, the influence of spatial and temporal variations in pore pressure within PDCs has yet to be investigated. Theory suggests that...
