ABSTRACT
This case presents integrated geophysical surveys carried out as part of a ground investigation for the proposed widening of an existing road. The work was designed to provide detailed information on the geology and ground conditions with particular concern for potential landslips. The geophysical survey consisted of an integrated approach utilising electromagnetic ground conductivity, electrical resistivity tomography (ERT), and P- and S-wave refraction and multichannel analysis of surface waves (MASW) along all ERT lines. The case includes practical survey and planning considerations along with examples of interpretations and results.
