The nature of the subsurface is important to humans for a number of reasons. We build our houses and infrastructure on the surface thus the structural integrity of the subsurface is important. A substantial percentage of our drinking water comes from groundwater aquifers and contamination of these aquifers by effluent or leachate from landfill sites is a major concern for many individuals, states and even countries. In addition, most of our energy resources and virtually all our mineral and aggregate resources are obtained from the subsurface. Geophysical techniques provide the tools we require in order to obtain useful information about the subsurface. Geophysics is a science that transcends the usual disciplinary boundaries and thus this book will also be beneficial for engineers, planners, archaeologists, hydrologists, geographers and environmental scientists. Aims and scope of the book are: to explain the theoretical basis behind the main geophysical techniques used in environmental investigations; to discuss the equipment used in such investigations and to provide case studies of the use of the techniques.

This new edition of the well-established Kearey and Brooks text is fully updated to reflect the important developments in geophysical methods since the production of the previous edition. The broad scope of previous editions is maintained, with even greater clarity of explanations from the revised text and extensively revised figures. Each of the major geophysical methods is treated systematically developing the theory behind the method and detailing the instrumentation, field data acquisition techniques, data processing and interpretation methods. The practical application of each method to such diverse exploration applications as petroleum, groundwater, engineering, environmental and forensic is shown by case histories. The mathematics required in order to understand the text is purposely kept to a minimum, so the book is suitable for courses taken in geophysics by all undergraduate students. It will also be of use to postgraduate students who might wish to include geophysics in their studies and to all professional geologists who wish to discover the breadth of the subject in connection with their own work.

The full potential of geophysics in engineering investigations is still to be realised. The many available techniques can provide important information about the ground, its mass properties, its small-scale variations, and its anomalies of structure or content. The advantage of a geophysical survey is that it enables information to be obtained for large volumes of ground that cannot be investigated by direct methods due to cost. The applications of geophysics in the characterisation of contaminated land are still developing, but have great potential for example in the distribution and migration of pollutants in the ground and groundwater. Geophysics is still insufficiently or inappropriately used in engineering and the newer capabilities are not appreciated, so there is a need for up-to-date guidance about how to apply geophysical investigations.This report is published in co-operation with the Geological Society and presents a logical guide through the process of using geophysical investigation methods in site characterisation. It explores the roles of geophysical methods and provides the background to geophysics as an investigative tool. The procurement, management and reporting frameworks for a geophysical investigation are set out, and the importance of the involvement of a recognised geophysics specialist adviser with the work is emphasised. The report explains the need for a conceptual ground model to enable appropriate investigative methods to be chosen. The underlying science and current practices of the main techniques are explained as well as the processes of data acquisition, handling and presentation. The different targets determinable by geophysical methods are considered in separate sections for geological, geotechnical, geo-environmental and structural engineering applications. The report concludes with recommendations for practice. The guide is aimed at geotechnical and civil engineers, geologists and engineering geologists, specialist geophysics contractors, contractors, consultants and clients.

"The self-potential method is a simple yet innovative process, enabling non-intrusive assessment and imaging of disturbances in electrical currents of conductive subsurface materials, by measuring the electrical response at the ground's surface or in boreholes. It has an increasing number of applications, from mapping fluid flow in the subsurface of the Earth, to understanding the plumbing systems of geothermal fields, and detecting preferential flow paths in earth dams and embankments"--

This scholarly text provides an introduction to the numerical methods used to model partial differential equations, with focus on atmospheric and oceanic flows. The book covers both the essentials of building a numerical model and the more sophisticated techniques that are now available. Finite difference methods, spectral methods, finite element method, flux-corrected methods and TVC schemes are all discussed. Throughout, the author keeps to a middle ground between the theorem-proof formalism of a mathematical text and the highly empirical approach found in some engineering publications. The book establishes a concrete link between theory and practice using an extensive range of test problems to illustrate the theoretically derived properties of various methods. From the reviews: "...the books unquestionable advantage is the clarity and simplicity in presenting virtually all basic ideas and methods of numerical analysis currently actively used in geophysical fluid dynamics."
