A suite of techniques which seek to determine the location and arrangement of materials and features in the subsurface by remotely detecting their physical properties and/or contrasts in their physical properties with the surrounding ground.
Geophysical surveying is just one set of tools available to investigate the subsurface. Normally, the acquisition and interpretation of geophysical data are planned as part of an integrated ground investigation to obtain representative information across large continuous areas of the site and/or to provide specific targeted information on areas of concern highlighted by desk study information or previous phases of ground investigation.
When considering the use of geophysics as part of the investigation, the engineer should consult a qualified professional geophysicist to advise on the likelihood or otherwise of the survey returning the information required by the client and also establish the accuracy and resolution that is...
