During the last ten years a number of ground subsidence events have occurred in the northwest part of Reading. Many of the subsidence events resulted in structural damage to existing properties (see Plates 1 and 2). On the basis of the properties inspected to date it appears that the local housing has been constructed mostly upon conventional strip footings bearing onto naturally occurring soils. The increasing number of recorded subsidence events is of concern to planners, developers and insurers. Consequently the aim of the survey was to identify the nature and extent of subsidence hazard in the local area.

This volume presents a collection of papers on techniques and case studies in land surface evaluation for engineering practice written by specialist practitioners in the field. The volume arose out of deliberations by the Second Working Party on Land Surface Evaluation set up by the Engineering Group of the Geological Society in January 1997 and chaired by Dr. J. S. Griffiths. The book examples of cost-effective methods for collecting land surface and near surface data prior to carrying further detailed ground investigations of engineering geologist, geotechnical engineers, geomorphologist and planners who have the responsibility for planning a designing investigations of potential sites of development.
