Develop a Greater Understanding of How and Why Surface Wave Testing Works
Using examples and case studies directly drawn from the authors’ experience, Surface Wave Methods for Near-Surface Site Characterization addresses both the experimental and theoretical aspects of surface wave propagation in both forward and inverse modeling. This book accents the key facets associated with surface wave testing for near-surface site characterization. It clearly outlines the basic principles, the theoretical framework and the practical implementation of surface wave analysis. In addition, it also describes in detail the equipment and measuring devices, acquisition techniques, signal processing, forward and inverse modeling theories, and testing protocols that form the basis of modern surface wave techniques.
Review Examples of Typical Applications for This Geophysical Technique
Divided into eight chapters, the book explains surface wave testing principles from data measurement to interpretation. It effectively integrates several examples and case studies illustrating how different ground conditions and geological settings may influence the interpretation of data measurements. The authors accurately describe each phase of testing in addition to the guidelines for correctly performing and interpreting results. They present variants of the test within a consistent framework to facilitate comparisons, and include an in-depth discussion of the uncertainties arising at each stage of surface wave testing.
- Provides a comprehensive and in-depth treatment of all the steps involved in surface wave testing

"… understanding the philosophy behind near surface site characterization surveys using surface waves, associated error analysis, and limitations in data interpretation may appear excessively complicated for students, or for researchers from different fields. The authors aim to fix this problem by providing a complete overview of surface wave methods and by describing every single step of data analysis including the field equipment and data acquisition in detail. … this book will be a very good source of knowledge for graduate students and engineers, but also for researchers from different fields who want to study site characterization using surface waves."

"Overall, the book reads as a single unified treatment of the subject area and avoids the common pitfall of appearing to be a collection of separate but related topic areas written by different authors. … for both those researchers interested in the detailed physics and mathematics underlying the method as well as for practitioners interested in proper application of the SWMs to real-world site characterization, this book is highly recommended."

"At last a definitive book on the acquisition of ground properties by surface waves! In the past, geotechnical engineers have lacked a readily accessible guide and body of knowledge in one state-of-the-art volume to give them the confidence to use this hugely important method of site characterization. Now engineers can have this guide on how to quickly and non-invasively test large volumes of soil to give overall dynamic (small strain) soil properties used in the prediction of static surface settlements and lateral ground movements. The increasingly wide-spread use of the method must surely follow the publication of this book that will become a standard on the bookshelves of academics and practitioners alike."

"This book gives an excellent overview of surface wave methods as well as detailed and rigorous insights on various aspects of such methods. It is thus an invaluable source of information for practitioners, students and researchers."

"Simple, clear and objective… In this book the techniques for useful geotechnical engineering applications are explained with rigor and detail, namely for ground profiling and characterization, soil improvement, characterization of pavements and detection of anomalies. In addition to outlining these problems, a chapter with case histories allows the reader to understand how the topics covered in the book can be applied to practical design. This book will be an excellent base for teaching in undergraduate and post-graduate level, and will be very useful for geophysical and geotechnical engineering practitioners."
