Profile

Elisabeth Bowman is a graduate of the University of Cambridge and spent several years in consulting practice in between her studies in general (civil) engineering and geotechnical engineering. She received her PhD in 2002 for research on the mechanics of creep and ageing of freshly disturbed granular materials. She then spent a three year Royal Academy of Engineering postdoctoral Fellowship at the University of Cambridge exploring the mechanics of large and catastrophic landslides via physical modelling. This led to her joining the academic staff at the University in Canterbury in Christchurch, New Zealand, where she gained valuable field experience in investigating landslide and earthquake behaviour as well as continuing with experimental research and numerical modelling of slope stability / landslide mechanics. She returned to the UK and joined the University of Sheffield in May 2013.

Elisabeth’s research interests lie in understanding the micro-mechanisms of geomaterials undergoing deformation, leading observed macro-scale behaviour. This has led to her current research into the following topics:

  • Creep of granular soils leading to observed ageing effects (as exhibited as increases in strength with time of freshly deposited sands, as displacement pile “set up” in granular soils, and as an increased resistance of older deposits to seismically-induced liquefaction)
  • Mechanisms behind the extraordinary spreading of large and catastrophic rock avalanches
  • Mechanics of the motion of debris flows with a view to better modelling of their runout behaviour
  • Behaviour of granular flows within geotechnical centrifuge physical model experiments (influences of Coriolis and other induced effects)
  • Internal erosion of susceptible soils (such as glacial tills), which may lead to internal instability in embankment dams, levees and canals
  • Local deformation modes of model geosynthetic reinforced soil walls under seismic loading

Recent activities and achievements

  • Associate Editor for Canadian Geotechnical Journal (2013 - ) 
  • Editorial Panel Member for Proceedings of ICE – Geotechnical Engineering (2009 - 2012)
  • Secretary of International Society of Soil Mechanics and Geotechnical Engineering Technical Committee (TC) 208: “Slope Stability in Engineering Practice” (2010 - )
  • Recipient of the 2013 Casimir Gzowski Medal, Canadian Society for Civil Engineering, for the paper “Physical models of rock avalanche spreading with dynamic fragmentation”
  • Recipient of a 2013 Telford Premium Prize, Institution of Civil Engineers, for the paper “Internal imaging of saturated granular free surface flows”

Research project(s)

An EPSRC collaboration between Imperial College London and the University of Sheffield - SEEPAGE INDUCED GEOTECHNICAL INSTABILITY

This research will exploit recent developments in modelling and imaging technologies to improve understanding of the mechanisms that underlie deformations and failures caused by seepage induced soil instability. This research will improve understanding of internal instability by studying the fundamental particle scale mechanisms involved. Two research teams with complementary expertise...
