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), doi: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... Read More

Fracture and damage localization in volcanic edifice rocks from El Hierro, Stromboli and Tenerife (2018)
Journal Article
Harnett, C. E., Benson, P. M., Rowley, P., & Fazio, M. (2018). Fracture and damage localization in volcanic edifice rocks from El Hierro, Stromboli and Tenerife. Scientific reports, 8(1), doi:10.1038/s41598-018-20442-w. ISSN 2045-2322

We present elastic wave velocity and strength data from a suite of three volcanic rocks taken from the volcanic edifices of El Hierro and Tenerife (Canary Islands, Spain), and Stromboli (Aeolian Islands, Italy). These rocks span a range of porosity a... Read More

Morphological and Mechanical Biomimetic Bone Structures (2016)
Journal Article
Parwani, R., Curto, M., Kao, A. P., Rowley, P. J., Pani, M., Tozzi, G., & Barber, A. H. (2017). Morphological and Mechanical Biomimetic Bone Structures. ACS Biomaterials Science and Engineering, 3(11), (2761-2767). doi:10.1021/acsbiomaterials.6b00652. ISSN 2373-9878

Cortical bone is an example of a mineralized tissue containing a compositional distribution of hard and soft phases in 3-dimensional space for mechanical function. X-ray computed tomography (XCT) is able to describe this compositional and morphologic... Read More

Key future directions for research on turbidity currents and their deposits (2015)
Journal Article
Felletti, F., Hill, P. R., Covault, J. A., Girardclos, S., Hansen, E., Hiscott, R. N., …Xu, J. (2015). Key future directions for research on turbidity currents and their deposits. Journal of Sedimentary Research, 85(2), (153-169). doi:10.2110/jsr.2015.03. ISSN 1527-1404

Turbidity currents, and other types of submarine sediment density flow, redistribute more sediment across the surface of the Earth than any other sediment flow process, yet their sediment concentration has never been measured directly in the deep oce... Read More

Experimental study of dense pyroclastic density currents using sustained, gas-fluidized granular flows (2014)
Journal Article
Rowley, P. J., Roche, O., Druitt, T. H., & Cas, R. (2014). Experimental study of dense pyroclastic density currents using sustained, gas-fluidized granular flows. Bulletin of volcanology, 76(9), (1-13). doi:10.1007/s00445-014-0855-1. ISSN 0258-8900

We present the results of laboratory experiments on the behaviour of sustained, dense granular flows in a horizontal flume, in which high-gas pore pressure was maintained throughout the flow duration by continuous injection of gas through the flume b... Read More

Conditional frequency mapping of move reservoir sedimentation models for improved play assessment (2012)
Presentation / Conference
Waltham, D. A., Rowley, P. J., Burgess, P. M., & MacLean, S. (2012, February). Conditional frequency mapping of move reservoir sedimentation models for improved play assessment. Paper presented at Petroleum Play Assessment, Malaga, Spain

Stratigraphic forward models encode what we know about dynamic stratigraphy in the form of a numerical model that can make various types of predictions of stratal geometries and facies distributions. Unfortunately, limited knowledge of the physical l... Read More

Shear-derived mixing in dense granular flows (2011)
Journal Article
Rowley, P. J., Kokelaar, P., Menzies, M., & Waltham, D. (2011). Shear-derived mixing in dense granular flows. Journal of Sedimentary Research, 81(12), (874-884). doi:10.2110/jsr.2011.72. ISSN 1527-1404

In flume experiments, granular avalanches run onto loose substrates develop 3-D architectures that record shear-derived mixing between the flow and the substrate. Spherical silica beads 0.250 mm diameter are run onto stratified substrates of various... Read More
