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.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the contributions of several authors and attempts to describe the roles human activities play in causing geohazards either directly or indirectly through man-made climate change. The risk of these man-made geohazards and the risk assessment are also discussed in this book. Each chapter keeps the authors' notations that vary from chapter to chapter. These authors' notations have been maintained to reduce unintended confusion and errors. Readers should be aware of this variation.
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 and published by Utah Geological Survey. This book was released on 2005-08 with total page 34 pages. 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

Download or read book Tectonic Geomorphology written by Douglas W. Burbank and published by John Wiley & Sons. This book was released on 2011-11-02 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tectonic geomorphology is the study of the interplay between tectonic and surface processes that shape the landscape in regions of active deformation and at time scales ranging from days to millions of years. Over the past decade, recent advances in the quantification of both rates and the physical basis of tectonic and surface processes have underpinned an explosion of new research in the field of tectonic geomorphology. Modern tectonic geomorphology is an exceptionally integrative field that utilizes techniques and data derived from studies of geomorphology, seismology, geochronology, structure, geodesy, stratigraphy, meteorology and Quaternary science. While integrating new insights and highlighting controversies from the ten years of research since the 1st edition, this 2nd edition of Tectonic Geomorphology reviews the fundamentals of the subject, including the nature of faulting and folding, the creation and use of geomorphic markers for tracing deformation, chronological techniques that are used to date events and quantify rates, geodetic techniques for defining recent deformation, and paleoseismologic approaches to calibrate past deformation. Overall, this book focuses on the current understanding of the dynamic interplay between surface processes and active tectonics. As it ranges from the timescales of individual earthquakes to the growth and decay of mountain belts, this book provides a timely synthesis of modern research for upper-level undergraduate and graduate earth science students and for practicing geologists.

Download or read book The Geology of Kane County Utah written by Hellmut H. Doelling and published by Utah Geological Survey. This book was released on 1989-01-25 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kane County, with its 4105 square miles, lies along the south-central margin of Utah and is found in the western part of the Colorado Plateaus physiographic province. It is famous for scenic beauty displayed in its colorful rock formations and other geologic features such as faults, folds, arches, monoclines, joints, cross beds, cliffs, lava fields, and canyons. Kane County contains parts of Bryce and Zion National Parks, the Glen Canyon Recreation Area, and it is home to the Coral Pink Sand Dunes and Kodachrome Basin State Parks. The county area has had an interesting geologic history and important fossil finds have added much to our knowledge of world geology. The total value of the mineral production of Kane County, Utah through 1985 is estimated at $21,854,000, of which more than 95 percent is attributed to construction materials, mined or quarried to build and maintain highways. Sand and gravel, crushed stone, coal, gemstones, pumice and volcanic ash, manganese ore, gold, uranium, silver, copper and lead were or have been produced, with the most important current commodities being construction and gem materials. The annual rate of production of these items is erratic, but the value averages a few hundred thousand dollars annually. The production of the construction materials is dependent on the schedules of the Utah Department of Transportation and other road building agencies. Gem materials are mined intermittently to supply the tourist trade. Currently, there are no large, regularly producing mining operations in the county. Other mineral deposits reported in Kane County include titanium and zirconium, gypsum and anhydrite, limestone and dolomite, clay, and vanadium. About 29 tests for petroleum have thus far been drilled without significant success. However, many had interesting shows of oil and gas and the potential for discovery remains high. 192 pages + 10 plates
