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 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 River Variability and Complexity written by Stanley A. Schumm and published by Cambridge University Press. This book was released on 2007-08-27 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers differ among themselves and through time. An individual river can vary significantly downstream, changing its dimensions and pattern dramatically over a short distance. If hydrology and hydraulics were the primary controls on the morphology and behaviour of large rivers, we would expect long reaches of rivers to maintain characteristic and relatively uniform morphologies. In fact, this is not the case - the variability of large rivers indicates that other important factors are involved. River Variability and Complexity presents an interesting approach to the understanding of river variability. It provides examples of river variability and explains the reasons for them, including fluvial response to human activities. Understanding the mechanisms of variability is important for geomorphologists, geologists, river engineers and sedimentologists as they attempt to interpret ancient fluvial deposits or anticipate river behaviour at different locations and through time. This book provides an excellent background for graduates, researchers and professionals.

Available in PDF, EPUB and Kindle. Book excerpt: Disasters by Design provides an alternative and sustainable way to view, study, and manage hazards in the United States that would result in disaster-resilient communities, higher environmental quality, inter- and intragenerational equity, economic sustainability, and improved quality of life. This volume provides an overview of what is known about natural hazards, disasters, recovery, and mitigation, how research findings have been translated into policies and programs; and a sustainable hazard mitigation research agenda. Also provided is an examination of past disaster losses and hazards management over the past 20 years, including factorsâ€"demographic, climate, socialâ€"that influence loss. This volume summarizes and sets the stage for the more detailed books in the series.
