This online seminar from the Association of Geotechnical and Geoenvironmental Specialists will focus on ground risk, in particular landslide risk reduction.
This event will see three expert speakers; Professor Mike Winter, (Winter Associates), Ian Nettleton, (Coffey Geotechnics Limited, A Tetra Tech Company) and Dr Andrew Ridley, (Geotechnical Observations), share their expertise on landslide hazards and risk assessment, monitoring and mitigation.
This webinar will be of interest to all those in the ground engineering sector who deal with the mitigation of ground instability risks and all those in the profession who wish to learn more about landslide risk identification, assessment and impacts.
Landslide Risks to Road Users, Road Infrastructure and Socio-economic Activity
Presented by Professor Mike Winter, Director at Winter Associates Limited
Fast-moving, rainfall-induced debris flow events are relatively common in the mountainous areas of the UK. Their impacts encompass the economic and social as well as the physical risk to infrastructure and people. The assessment of such landslide hazards and risks forms an essential precursor to landslide risk reduction whether via management and mitigation. This is particularly the case when an authority is responsible for an infrastructure or building portfolio that may be affected by multiple hazards and/or hazard types.
Debris flows often sever (or delay) access to and from relatively remote communities for services and markets for goods; employment, health and educational opportunities; and social activities.
Semi-quantitative risk assessment, at the regional scale, and quantitative risk assessment, at the site scale, of the risks that debris flow hazards pose to road users will be described. Specific risks include road user fatality, road infrastructure damage and the socio-economic activities that road networks facilitate. Economic impacts will be quantified and the way in which their extent can be defined by the vulnerability shadow will be described along with emerging approaches to understanding infrastructure vulnerability.
If time allows, the effects of climate change on debris flow hazard and risk will also be considered in the context of likely changes to hazard frequency and/or magnitude and changes to risk.
A strategic approach to risk reduction allows a clear focus on the overall goal of risk reduction before homing in on the desired outcomes and the generic approach to achieving those outcomes.
AGS Chair Elect and Regional Manager & Associate at Coffey Geotechnics Limited, A Tetra Tech Company
Sally has 30 years’ experience in the ground engineering industry and has responsibility for the delivery and management of geotechnical risk on a wide range of projects.
She has worked in the site investigation field for specialist contractors and for design consultancies on many major transport and energy infrastructure schemes, on earthworks design schemes and asset management in the road, rail and energy sectors.
Sally has more recently concentrated on business development and technical management of geotechnical operations within Coffey in the UK and has been the AGS Business Practice Working Group Leader since 2019.
Managing Director at Geotechnical Observations Limited
Andrew Ridley is the Managing Director of Geotechnical Observations Ltd (GeO), which he founded in 2000. GeO specialise in the installation, reading, reporting and interpretation of geotechnical instrumentation.
Andrew obtained his first degree in Civil Engineering from the University of Nottingham in 1984, followed it with a Master’s Degree in Soil Mechanics from Imperial College London in 1988 and was awarded a PhD by Imperial College in 1993 for his work on “the measurement of soil moisture suction.”
He has served on the Editorial Panel of Geotechnical Engineering (the proceedings of the ICE), the Editorial Panel of Géotechnique for the 2011 Symposium in Print on Partial Saturation in Compacted Soils, the Steering Committee for CIRIA 550 Infrastructure Embankments – Condition Appraisal and Remedial Treatment and represents FMGM (Field Measurements in Geomechanics) on the BGA (British Geotechnical Association) committee. He is also the UK representative on ISO/TC182/WG2, which is drafting International Standards for geotechnical instrumentation and monitoring and is Chair of ISSMGE TC220 on Field Measurements in Geomechanics.
In 2016 he was awarded the John Mitchell Gold Medal by the Institution of Civil Engineers in recognition of his contributions to geotechnical engineering.
Director at Winter Associates Limited
Mike is Director of Winter Associates Limited, the company that he started in 2019 after 30 years in applied research and specialist consultancy at TRL.
His areas of expertise include landslides and their hazard and risk assessment, and management and mitigation; soil materials, compaction and earthworking; and the use of waste materials in geo-structures. His work has been widely-adopted in teaching and practice from his near-300 publications.
Former Chief Scientific Editor of QJEGH, he led the organisation of XVI ECSMGE, the largest UK Civil Engineering event, and Executive Member of the ISSMGE TC202 on Transportation Geotechnics. He is Visiting Industrial Professor of Engineering Geology and Geotechnics at the University of Portsmouth, and Visiting Professor in the UNESCO-Chair Programme on Geoenvironmental Disaster Reduction at Shimane University, Matsue, Japan.
Mike has lectured and worked in 35 countries and on each of the world’s continents, with the major exception of Antarctica – in this respect Mike remains open to offers.
