Prof. John Reynolds will give a presentation on "The role of engineering geophysics during economic austerity". He will describe the benefits of using geophysical techniques in ground investigations through case studies. Integrating modern technology in data acquisition and analysis has revolutionized geophysics over the last decade by allowing 3D ground models to be exported to various software formats. Several examples will show where geophysics has not been used effectively and guidance will be provided on better survey design. The presentation will conclude with case studies of how geophysics informed major tunnel construction strategies.
