Sinkholes and crown holes in Hertfordshire from 2000 to 2019

A spatial review of the PBA Natural Cavity and Mining Cavity databases shows that ground subsidence problems are widespread across Hertfordshire. 

In recent years a number of ever larger collapses have occurred at intervals. The impacts of climate and man-made factors over time will be presented. The history of subsidence activity will be supported with reference to a series of case studies in relation to Hatfield, Hemel Hempstead, Hertford and St Albans which will look at the investigations into the causes and stabilisation.

Speaker

Clive Edmonds, BSc, MSc, PhD, DIC, FGS, CGeol, EurGeol, CSci

Clive joined Peter Brett Associates in 1997 and became a partner in 2006. He has about 30 years’ experience having worked throughout the UK and in parts of Europe and Asia.

He typically leads projects with significant geological, geomorphological and geotechnical issues, particularly instability. He is a leading UK expert in the investigation and solving of ground instability problems especially relating to natural cavities (karst)and mining cavities.  

Through academic studies and commercial experience he has developed geomorphological modelling, geohazard mapping and risk assessment techniques for sites underlain by karst and mines. 

Major projects include:  

  • a national study of natural cavity instability in Great Britain; 
  • development of national databases for natural cavities and mining cavities; 
  • large scale investigations and remedial stabilisation works (up to values of £12 million) for subsidence damaged properties in Reading, Hatfield, Hemel Hempstead and elsewhere; 
  • and numerous subsidence insurance claims.

Clive has acted as expert witness for public inquiries, ruling court and litigation cases, has been interviewed on TV and radio, and has authored more than 30 technical papers/books and lectured widely.
