Book Description
This 116-page report presents the results of an investigation by the Utah Geological Survey of land subsidence and earth fissures in Cedar Valley, Iron County, Utah. Basin-fill sediments of the Cedar Valley Aquifer contain a high percentage of fine-grained material susceptible to compaction upon dewatering. Groundwater discharge in excess of recharge (groundwater mining) has lowered the potentiometric surface in Cedar Valley as much as 114 feet since 1939. Groundwater mining has caused permanent compaction of fine-grained sediments of the Cedar Valley aquifer, which has caused the land surface to subside, and a minimum of 8.3 miles of earth fissures to form. Recently acquired interferometric synthetic aperture radar imagery shows that land subsidence has affected approximately 100 mi² in Cedar Valley, but a lack of accurate historical benchmark elevation data over much of the valley prevents its detailed quantification. Continued groundwater mining and resultant subsidence will likely cause existing fissures to lengthen and new fissures to form which may eventually impact developed areas in Cedar Valley. This report also includes possible aquifer management options to help mitigate subsidence and fissure formation, and recommended guidelines for conducting subsidence-related hazard investigations prior to development.

Land Subsidence Mitigation
Author: Frank R. SpellmanPublisher: CRC Press
ISBN: 1351617567
Category : Science
Languages : en
Pages : 425
Book Description
This book examines the process of injecting treated wastewater into wells to replenish aquifers, and thereby slow the process of land subsidence, and help to mitigate coastal flooding. It explains how up to fifty percent of sea-level rise may be due to land subsidence, and up to fifty percent of land subsidence may be due to aquifer compaction. The concepts covered discuss replenishing aquifers with clean water to reduce nutrient discharges into out-falled waterways; providing a sustainable supply of groundwater; reducing the rate of land subsidence; and protecting the groundwater from saltwater intrusion. Practical case studies from Virginia and California will be included.

Book Description
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.

Book Description
This book is one out of six IAEG XIII Congress and AEG 61st Annual Meeting proceeding volumes, and deals with topics related to geologic hazards, such as earthquakes, land subsidence, coastal hazards, and the emergency response. The theme of the IAEG/AEG Meeting, held in San Francisco from September 17-21, 2018, is Engineering Geology for a Sustainable World. The meeting proceedings analyze the dynamic role of engineering geology in our changing world. The meeting topics and subject areas of the six volumes are: Slope Stability: Case Histories, Landslide Mapping, Emerging Technologies; Geotechnical and Environmental Site Characterization; Mining, Aggregates, Karst; Dams, Tunnels, Groundwater Resources, Climate Change; Geologic Hazards: Earthquakes, Land Subsidence, Coastal Hazards, and Emergency Response; and Advances in Engineering Geology: Education, Soil and Rock Properties, Modeling.
