My research is aimed at understanding fundamental physical processes in geotechnical systems in order to improve the resilience of infrastructure such as embankment dams and subsurface pipe networks and to reduce the risk of geotechnical hazards such as landslides.
Dr Elisabeth (Lis) Bowman
I am a Chartered geotechnical engineer (CEng MICE) and researcher working at the interface of geotechnical engineering, geology, granular physics and fluid mechanics.
I took my Bachelors degree at the University of Cambridge, then worked for four years as a civil engineer for consultants Gifford in Southampton and London before returning to study for a PhD in geotechnical engineering at Cambridge, focused on the ageing of granular soils and set up of displacement piles. I was subsequently awarded a Royal Academy of Engineering Postdoctoral Fellowship to study the mechanics of rapid landslides at Cambridge, then spent eight years at the University of Canterbury in New Zealand experiencing geology in real time (read: landslides and earthquakes) before returning to the UK to the University of Sheffield.
My research is focused on understanding, thereby mitigating, processes that destabilise soil and enhancing processes that improve soil behaviour, thereby reducing risk for subsurface and near-surface civil infrastructure. Example applications include: measuring and modelling internal erosion in embankment dams and under pipe leakage, quantifying the particulate processes that lead to rapid landslides and developing new models for complex processes such as soil creep and ageing that affect the behaviour of buried infrastructure.
Such diverse problems follow a central theme of investigating the localization of soil constitutive behaviour through material change at the fluid-particle level, informed by experiments and observation at the field scale. Investigative methods include advanced element testing and development of new equipment, physical modelling (via the geotechnical centrifuge and using 1g models) with novel imaging techniques, and field mapping. An important aspect of this approach is assembling and working in multidisciplinary technical teams to tackle problems from a diversity of perspectives particulate, fluid and structural. My group have developed a number of experimental innovations including:
- transparent soil (refractive index matching) experimental techniques to examine internal erosion and debris flow mechanisms towards improved model outcomes
- centrifuge methods to handle high speed motion (Coriolis effects) to develop new understanding of rock avalanche and debris flow motion
- a stress path permeameter and centrifuge permeameter to examine seepage related problems under complex stress states
My work branching into granular physics has been recognised by invited keynote contributions to multidisciplinary events including the Gordon Research Conference on Particulate Systems, USA (2022 & 2024), Salamina Grains Workshop, Italy (2024), Lorentz Center Workshop Image is Everything Netherlands (2023) and GeoFlow2016 on two-phase continua, Max Planck Institute (MPIPKS), Germany (2016). I have been an Associate Editor for Canadian Geotechnical Journal since 2013 and previously sat on the Royal Academy of Engineerings Industrial Fellowship Steering Committee (2016-2020) and Research Committee (2020-2023). On the engineering practice side, I currently act as the Geotechnical Lead on the Reservoir Safety Research Advisory Group (ResRAG) under the aegis of the British Dam Society and I am also the university liaison for the Yorkshire Geotechnical Group.
I currently teach the final year Meng / MSc Geotechnical Infrastructure module focused on putting soil mechanics into practice for design and appraisal of dams, levees and tunnels. I previously taught the second year geotechnical module, for which I received the 2022 Vice-Chancellor's Award for Teaching Practice in the Faculty of Engineering.

Particle-Scale Investigation of Seepage Induced Geotechnical Instability
Awareness is growing that seepage forces imparted on individual particles can preferentially erode the smaller particles in sandy soils. There can be significant internal erosion of the soil under scenarios that are considered safe according to the classical continuum calculations used in engineering practice; this phenomenon is called internal instability.
The Rosetta Stone Network: Physical testing towards a common unstanding of debris flow
This project aims to create a Rosetta Stone of communication between the disciplines through physical tests undertaken with common material characteristics, informed by monitored field events, leading to improved numerical models.
