Subsidence Induced by Fossil Fuel ExtractionThis book covers a range of topics that are of increasing importance in engineering practice: natural hazards, pollution, and environmental protection through good practice. The first half of the book deals with natural risk factors, of both natural and human origin, that should be considered: subsidence, accidental infiltration, soil instability, rockslides and mudslides, debris flow, and degradation of buildings and monuments due to pollution and climactic effects, for example. These problems are highlighted and it is shown that a combination of sophisticated numerical techniques and eISTEEnvironmental geotechnologySoil pollutionEnvironmental geotechnology.Soil pollution.628.5/5Schrefler B.
