Clive Edmonds to give keynote lecture at Chalk 2018 Conference

The Chalk 2018 Conference Committee is pleased to announce that Dr Clive Edmonds will deliver a Keynote Lecture at the conference in September 2018.

Clive Edmonds is a partner at Peter Brett Associates LLP. He has 30 years’ experience in geological, geomorphological and geotechnical issues, particularly relating to instability in Chalk. Through academic studies and commercial experience he has developed geomorphological modelling, mapping, monitoring and risk assessment techniques for unstable land. He has been involved in a national study of natural cavity instability in Great Britain and the development of national land stability databases. He has authored more than 40 technical papers/articles/books and has lectured widely.

Dr Edmonds’ keynote will be entitled Review of Collapse Events on Chalk Since 2000 and the Opportunity for Improvement.

It will discuss major collapse events across the Chalk outcrop since 2000, many of which have resulted in damage to buildings, infrastructure and risks to people followed by expensive remedial works. The collapse events include both naturally formed sinkholes and man-made crown holes. The majority of collapses have been triggered by water inundation, either as a result of particularly heavy rainfall or leaking utility services.

Compilation of natural cavity and mining cavity databases for the Chalk outcrop over more than 30 years has provided a useful archive for spatial analysis concerning the nature of cavity occurrence patterns and causal factors. Reviewing the geo-spatial setting of collapse events shows that there are several common characteristics. They can be used to identify areas of higher geo-hazard potential.

Learning from review of spatial patterns of collapse events provides opportunities to de-risk all forms of new development by incorporating improved resilience into design and construction for both new, and renewal of, existing development and infrastructure. The role of planners, developers and water utility owners is crucial to reduce the risks and impacts upon urban development and communities.
