Download or read book The Origin and Extent of Earth Fissures in Escalante Valley, Southern Escalante Desert, Iron County, Utah written by William R. Lund. This book was released on 2005-08. Available in PDF, EPUB and Kindle. Book excerpt: This CD contains a 30-page report and 37-photo appendix of an investigation by the Utah Geological Survey of five recently discovered earth fissures in southwestern Utah. The earth fissues, which likely resulted from aquifer compaction due to ground-water withdrawal, were revealed after floodwater infiltrated into and enlarged the fissures during January 2005. This study discusses the geology and hydrology of the Escalante Valley where the fissures formed, includes maps of the fissure traces, discusses the most probable cause of fissure formation, and presents recommendations for future study. 30 pages + 37 page appendix

Book Synopsis Investigation of land subsidence and earth fissures in Cedar Valley, Iron County, Utah by : Paul Inkenbrandt

Download or read book Investigation of land subsidence and earth fissures in Cedar Valley, Iron County, Utah written by Paul Inkenbrandt. This book was released on 2014-03-12. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis 2016GUIDELINES FOR INVESTIGATING GEOLOGIC HAZARDS AND PREPARING ENGINEERING-GEOLOGY REPORTS, WITH A SUGGESTED APPROACH TO GEOLOGIC-HAZARD ORDINANCES IN UTAH by : Steve D. Bowman

Download or read book 2016GUIDELINES FOR INVESTIGATING GEOLOGIC HAZARDS AND PREPARING ENGINEERING-GEOLOGY REPORTS, WITH A SUGGESTED APPROACH TO GEOLOGIC-HAZARD ORDINANCES IN UTAH written by Steve D. Bowman. This book was released on 2016-09-21. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of these guidelines for investigating geologic hazards and preparing engineering-geology reports, is to provide recommendations for appropriate, minimum investigative techniques, standards, and report content to ensure adequate geologic site characterization and geologic-hazard investigations to protect public safety and facilitate risk reduction. Such investigations provide important information on site geologic conditions that may affect or be affected by development, as well as the type and severity of geologic hazards at a site, and recommend solutions to mitigate the effects and the cost of the hazards, both at the time of construction and over the life of the development. The accompanying suggested approach to geologic-hazard ordinances and school-site investigation guidelines are intended as an aid for land-use planning and regulation by local Utah jurisdictions and school districts, respectively. Geologic hazards that are not accounted for in project planning and design often result in additional unforeseen construction and/or future maintenance costs, and possible injury or death.
