This book was released on 2013-10-15 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 43-page report presents new Interferometric Synthetic Aperture Radar (InSAR) analysis of ground water subsidence in Cedar Valley in Iron County, Utah. This analysis is based on InSAR data from the ERS-1/2 satellites from 1992 to 2000, and the Envisat satellite from 2004 to 2010. A stack of five consecutive interferograms from the 1992-2000 time period and a stack of four consecutive interferograms from the 2004-2010 time period are included in this report; however, decorrelation in the vicinity of the Enoch graben makes an estimate of total deformation impossible using the stacks. In total, surface deformation has impacted approximately 256 km² (100 mi²) in Cedar Valley. Subsidence rates in the vicinity of the Enoch graben increased from approximately 0.5-1.0 cm/yr to roughly 1-2 cm/yr after 1999. Similarly, rates in central Cedar Valley show a general increasing trend after 1999, but rates appear to be more erratic than the other two sites. The spatial distribution of deformation in Cedar Valley correlates well with both the location of observed fissuring as well as the location of both municipal and private groundwater production wells. The fissuring observed near Quichapa Lake, as well as within the Enoch graben, is likely a direct result of groundwater pumping in these areas.

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 and published by Utah Geological Survey. This book was released on 2016-09-21 with total page 217 pages. 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.

Bawden and published by CreateSpace. This book was released on 2012 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Houston-Galveston region—comprising Harris and Galveston Counties and adjacent parts of Brazoria, Chambers, Fort Bend, Grimes, Liberty, Montgomery, San Jacinto, Walker, and Waller Counties (fig. 1)—is one of the largest areas of subsidence in the United States (Galloway and others, 1999). Most of the subsidence in the Houston-Galveston region (which includes the greater Houston metropolitan area) has occurred as a direct result of groundwater withdrawals for municipal supply, industrial use, and irrigation that depressured and dewatered the major aquifers in the area, thereby causing compaction of the clay layers of the aquifer sediments (Kasmarek and others, 2010; Johnson and others, 2011). Groundwater has historically been the principal source of water for municipal, industrial, and agricultural uses, and groundwater use in the Houston-Galveston region had increased rapidly for many decades to meet the water needs of the rapidly growing population (Seifert and Drabek, 2006). Since the 1990s, surface water has been increasingly used to meet these water needs and reduce reliance on groundwater resources in the Houston-Galveston region (Kasmarek and Robinson, 2004).

Download or read book Investigation of land subsidence and earth fissures in Cedar Valley Iron County Utah written by Paul Inkenbrandt and published by Utah Geological Survey. This book was released on 2014-03-12 with total page 122 pages. 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.
