9 QUAL I TÉ GÉOPHYSIQUEAPPLIQUÉE Foreword 1 J.-L. Mari, M. Mendes Based on their experience in geophysics as applied to the oil and gas industry, and in the geotechnical field, the authors have set out to explain how conventional seismic methods used in deep exploration geophysics for imaging can be applied to certain geotechnical and hydrogeological surveys, and to site characterizations in the framework of seismic hazard studies. After reviewing the current state of knowledge in seismic wave propagation, refraction and reflection seismic methods, the book aims to describe how seismic tomography and full waveform inversion methods can be used to obtain seismic images of the subsurface. The book highlights the benefit of combining different seismic methods through various synthetic and field examples. In addition to these examples, the authors provide readers with guidelines to carry out these operations, in terms of acquisition, as well as processing and interpretation. The authors thank Hervé Chauris, Béatrice Yven and Michel Hayet for their contributions to this book.
