LAND SUBSIDENCE: CASE STUDIES AND CURRENT RESEARCH edited by James W. Borchers. Land Subsidence is a worldwide problem. Under the auspices of the Association of Engineering Geologists, carefully selected experts contributed papers to this comprehensive compendium The contributors, from the United State & 10 other countries include practitioners, researchers, planners & attorneys -- experts that you can depend upon. Current & historically significant research: Innovative theory & monitoring equipment. Case histories describing site exploration & evaluation. Predictive modeling. Damage to infrastructure. Engineering of remedial construction. Topics include: Migration or removal of subsurface fluid such as brine, salt water, hydrocarbons. Hydrocompaction of moisture deficient sediments: debris flow deposits, artificial fill. Oxidation of peat deposits. Collapse of underground ad solution mine voids. Tunneling. Karst terrain. Going beyond engineering geology & hydrology, this timely resource includes insight into political & legal issues. Offers an understanding of the public policy decision making processes related to land subsidence. Property rights & land use. Regulatory issues. Topics critical to consulting engineers, planners, developers, attorneys & geologists. Hardcover. 8 1/2 by 11 inches. Extensive illustrations! 576 pages.

Land subsidence (LS) is a gradual settling or sudden sinking of the Earth's surface owing to subsurface movement of earth materials. More than 80% of the identified LS in the nation is due to our exploitation of underground water (UW). This report illustrates the 3 basic mechanisms by which human influence on UW causes land subsidence: compaction of aquifer systems, dewatering of organic soils, and mass wasting through dissolution and collapse of susceptible earth materials. Also examines the role that water-management groups play in mitigating subsidence damages. Color and B&W photos, maps, and drawings.
