This book provides an overview of the SNMR method and a cost-benefit analysis of SNMR against other geophysical methods applied to groundwater study. It assesses the methodology of field measurements and gives examples of real data interpretation, and deals with some of the most pervasive problems faced by the SNMR methodology. Based on the author's extensive teaching experience, this book is designed to acquaint a wide but specialist audience of researchers and professionals in hydrogeology and geophysics with the SNMR method.Universities and research institutions.Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.Anatoly Legchenko graduated from the Electrotechnical Institute of Novosibirsk (USSR), as an engineer in computer sciences and electronics. His PhD diploma in physics and mathematics was awarded by the Computing Center of the Siberian Branch of the Russian Academy of Sciences after presentation of the thesis 'Inverse problems in geophysical NMR tomography'. In 2001, the diploma Habilitation ?a Diriger les Recherches in geophysics was awarded by the University Paris XI (France).Currently, Anatoly is a senior scientist in IRD attached to the Universit?e Grenoble Alpes (UGA, France).Title from PDF title page (viewed on December 6, 2021).
