This is the first book of its kind on seismic amplitude inversion in the context of reflection tomography. The aim of the monograph is to advocate the use of ray-amplitude data, separately or jointly with traveltime data, in reflection seismic tomography.
The emphasis of seismic exploration is on imaging techniques, so that seismic section can be interpreted directly as a geological section. In contrast it is perhaps ironic that, in decades of industrial seismology, one major aspect of waveform data that potentially is easier to measure and analyse has generally been ignored. That is, the information content of seismic amplitudes. Perhaps the potential complexity has deterred most researchers from a more thorough investigation of the practical use of seismic amplitude data. The author of this volume presents an authoritative and detailed study of amplitude data, as used in conjunction with traveltime data, to provide better constraints on the variation of seismic wave speed in the subsurface.
One of the fundamental problems in conventional reflection seismic tomography using only traveltime data is the possible ambiguity between the velocity variation and the reflector depth. The inclusion of amplitude data in the inversion may help to resolve this problem because the amplitudes and traveltimes are sensitive to different features of the subsurface model, and thereby provide more accurate information about the subsurface structure and the velocity distribution. An essential goal of this monograph is to make the amplitude inversion method work with real reflection seismic data.

Groundwater: Modelling, Management and Contamination
Author: Luka F. Konig (Editor) and Jonas L. Weiss (Editor) | Size: 12.3 MB | Format:PDF | Publisher: Nova Science Pub Inc | Year: 2008 | pages: 404 | ISBN: 1604568321 & 9781607413950
Product Description:
Groundwater (GW) is one of the most valuable natural resources and for that reason, the GW protection and management is vital for human evolution, socio-economic development and ecological diversity. During the last decades, the continuously increasing need of water has led to a rapidly growing awareness in the field of GW management. At the same time over exploitation and pollution of water resources are threatening the ecosystems. The combination of these two problems which have acquired world-wide dimensions has forced many scientists working in relative fields to search new, multidisciplinary approaches to address them. Effective management and protection of groundwater resources require detail knowledge and quantitative/qualitative characterisation of aquifers. Thus, modelling and planning of the GW through the use of modern technologies and approaches have become of high priority towards this direction. This book provides leading-edge research on this field.

This Springer Handbook of Metrology and Testing presents the principles of Metrology – the science of measurement – and the methods and techniques of Testing – determining the characteristics of a given product – as they apply to chemical and microstructural analysis, and to the measurement and testing of materials properties and performance, including modelling and simulation.
The principal motivation for this Handbook stems from the increasing demands of technology for measurement results that can be used globally. Measurements within a local laboratory or manufacturing facility must be able to be reproduced accurately anywhere in the world. The Commission of the European Union has expressed this as follows:
There is no science without measurements, no quality without testing, and no global markets without standards.
The Handbook is organized in five parts. Part A: Fundamentals of Metrology and Testing. Part B: Chemical and Microstructural Analysis. Part C: Materials Properties Measurement. Part D: Materials Performance Testing. Part E: Modeling and Simulation Methods.
