Download or read book Guidelines for the Geologic Evaluation of Debris flow Hazards on Alluvial Fans in Utah written by Richard E. Giraud and published by Utah Geological Survey. This book was released on 2005-06 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Utah Geological Survey (UGS) developed these guidelines to help geologists evaluate debris-flow hazards on alluvial fans to ensure safe development. Debris-flow hazard evaluations are particularly important because alluvial fans are the primary sites of debris-flow deposition and are also favored sites for development. The purpose of a debris-flow-hazard evaluation is to characterize the hazard and provide design parameters for risk reduction. The UGS recommends critical facilities and structures for human occupancy not be placed in active debris flow travel and deposition areas unless the risk is reduced to an acceptable level. These guidelines use the characteristics of alluvial fan deposits as well as drainage-basin and feeder-channel sediment-supply conditions to evaluate debris-flow hazards. The hazard evaluation relies on the geomorphology, sedimentology, and stratigraphy of existing alluvial fan deposits. Analysis of alluvial-fan deposits provides the geologic basis for estimating frequency and potential volume of debris flows and describing debris-flow behavior. Drainage-basin and feeder-channel characteristics determine potential debris-flow susceptibility and the volume of stored channel sediment available for sediment bulking in future flows.

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.

Download or read book Debris flow Hazards and Related Phenomena written by Matthias Jakob and published by Springer Science & Business Media. This book was released on 2007-12-26 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: With climate change and deforestation, debris flows and debris avalanches have become the most significant landslide hazards in many countries. In recent years there have been numerous debris flow avalanches in Southern Europe, South America and the Indian Subcontinent, resulting in major catastrophes and large loss of life. This is therefore a major high-profile problem for the world's governments and for the engineers and scientists concerned. Matthias Jakob and Oldrich Hungr are ideally suited to edit this book. Matthias Jakob has worked on debris flow for over a decade and has had numerous papers published on the topic, as well as working as a consultant on debris flow for municipal and provincial governments. Oldrich Hungr has worked on site investigations on debris flow, avalanches and rockfall, with emphasis on slope stability analysis and evaluation of risks to roads in built-up areas. He has also developed mathematical models for landslide dynamic analysis. They have invited world-renowned experts to joint them in this book.

Frary Peak, the island’s highest point, is 6,597feet (2,010 m) above sea level and about 2,400 feet (730 m) above the lake’s historical average level. Although the island is perhaps best known for its wildlife and relatively pristine condition, the island is also fascinating from a geological standpoint.
Download or read book Characteristics Causes and Implications of the 1998 Wasatch Front Landslides Utah written by Francis X. Ashland and published by Utah Geological Survey. This book was released on 2003 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of the 1998 Wasatch Front landslides were likely triggered following a cumulative rise in ground-water levels resulting from four or more successive years of above-normal precipitation. Triggering of landslide movement likely coincided with a transient ground-water-level rise associated with the spring snowmelt and contemporaneous above-normal precipitation. In most Wasatch Front areas, 1998 was the wettest as well as the last year of the precipitation period. An increase in landslide activity began in 1997, following two to four successive years of above-normal precipitation. This study examines the relation between the 1998 landslides and the 1995-98 precipitation period (1993-98 in Spanish Fork Canyon). Accordingly, this study investigates the significance of the most recent precipitation period in relation to the historical precipitation record, and compares it with the 1980-86 period. In addition, other causes of the 1998 landsliding are explored, most importantly hillside modification related to residential development. This study also examines several issues, and their implications, related to the 1998 Wasatch Front landslides including the susceptibility to reactivation of pre-existing landslides, consideration of the state of landslide activity, and the possibility of developing landslide-movement prediction tools based on an instability threshold concept. The majority of the landslides discussed occurred near urbanized areas of the Wasatch Front and consisted of either translational or rotational earth slides in pre-existing landslide areas. The discussion and conclusions are limited to these landslides and locations. The case histories presented provide new data intended to further the understanding of landslide hazards in the Wasatch Front.
Download or read book Geologic Evaluation and Hazard Potential of Liquefaction induced Landslides Along the Wasatch Front Utah written by Kimm M. Harty and published by Utah Geological Survey. This book was released on 2003 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to evaluate the potential for future movement of the landslides during earthquakes to determine the hazard these features may pose. Goals of the study were to: (1) determine when landslide movement occurred, (2) determine the failure mode (lateral spread versus flow failure), (3) determine if recurrent movement has occurred, (4) correlate, where possible, through radiocarbon dating, the timing of landslide movement(s) with the paleoseismic record from fault studies along the Wasatch Front, and (5) assess the current hazard from liquefaction-induced landslides along the Wasatch Front. Once the study was underway, it became evident that not all 13 landslides were liquefaction induced, or even landslides at all. Thus, an additional goal of the study became determining which of the 13 mapped landslides were liquefaction induced, which were not liquefaction induced, and which were formed by other processes. 40 pages + 16 plates

Download or read book Alluvial Fan Flooding written by National Research Council and published by National Academies Press. This book was released on 1996-10-07 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alluvial fans are gently sloping, fan-shaped landforms common at the base of mountain ranges in arid and semiarid regions such as the American West. Floods on alluvial fans, although characterized by relatively shallow depths, strike with little if any warning, can travel at extremely high velocities, and can carry a tremendous amount of sediment and debris. Such flooding presents unique problems to federal and state planners in terms of quantifying flood hazards, predicting the magnitude at which those hazards can be expected at a particular location, and devising reliable mitigation strategies. Alluvial Fan Flooding attempts to improve our capability to determine whether areas are subject to alluvial fan flooding and provides a practical perspective on how to make such a determination. The book presents criteria for determining whether an area is subject to flooding and provides examples of applying the definition and criteria to real situations in Arizona, California, New Mexico, Utah, and elsewhere. The volume also contains recommendations for the Federal Emergency Management Agency, which is primarily responsible for floodplain mapping, and for state and local decisionmakers involved in flood hazard reduction.
Download or read book Geologic Hazards of Moab Spanish Valley Grand County Utah written by Michael D. Hylland and published by Utah Geological Survey. This book was released on 2003 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Moab Valley and the contiguous Spanish Valley comprise a popular residential and recreational area in east-central Utah. Geologic processes that created the rugged and scenic landscape of Moab-Spanish Valley are still active today and can be hazardous to property and life. To address development in areas with geologic hazards, the Utah Geological Survey (UGS) conducted a geologic-hazards investigation to provide information to Moab City and Grand County to help guide development and reduce losses from geologic hazards. This report includes maps of Moab Valley and the northern and central parts of Spanish Valley that provide information on geologic hazards to assist homeowners, planners, and developers in making informed decisions. The maps show areas where hazards may exist and where site-specific studies are advisable prior to development. The maps are for planning purposes only, and do not preclude the necessity for site investigations. Site-specific studies by qualified professionals (engineering geologists, geotechnical engineers, hydrologists) should evaluate hazards and, if necessary, recommend hazard-reduction measures. Because of the small scale of the maps, some hazard areas are not shown; hazard studies are therefore recommended for all critical facilities (for example, hospitals, schools, fire stations), including those outside the mapped hazard areas.
