The Engineering Group will be hosting a one day meeting themed on Buried Hollows in the London Basin and surrounding areas. The presentations will address the possible modes of origin of these features, the challenges they present in ground investigation and their risk mitigation through ground engineering solutions, all illustrated with case studies
Catherine Cripps, Jonathan Lee (BGS) Evolution of the terminology associated with buried hollows.
Vanessa Banks, Don Aldiss, Stephanie Bricker, Claire Dashwood, Richard Ellison, David Entwisle, Richard Haslam, Jonathan Lee, Kate Royse (BGS) BGS contributions to the mapping and modelling of buried hollows in London.
Stephen Dixon, Richard Ghail (Imperial College), Richard Ball (CGL) Geological Control of Drift Filled Hollows: a case study at St. James's Square, London.
