Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive overview of the alluvial fan phenomena, including all terminology, morphology, sedimentology, controlling factors, processes and the human impact. It combines the knowledge dispersed widely in existing literature with regional case studies, color figures and photographs. The chapters provide a useful basis to understand alluvial fans and a selection of papers attached to each chapter offers additional, more focused reading. This volume is aimed at engineers, planners and especially students in earth sciences.

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 Alluvial Fans written by Adrian M. Harvey and published by Geological Society of London. This book was released on 2005 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alluvial fans are important sedimentary environments. They trap sediment delivered from mountain source areas, and exert an important control on the delivery of sediment to downstream environments, to axial drainages and to sedimentary basins. They preserve a sensitive record of environmental change within the mountain source areas. Alluvial fan geomorphology and sedimentology reflect not only drainage basin size and geology, but change in response to tectonic, climatic and base-level controls. One of the challenges facing alluvial fan research is to resolve how these gross controls are reflected in alluvial fan dynamics and to apply the results of studies of modern fan processes and Quaternary fans to the understanding of sedimentary sequences in the rock record. This volume includes papers based on up-to-date research, and focuses on three themes: alluvial fan processes, dynamics of Quaternary alluvial fans and fan sedimentary sequences. Linking the papers is an emphasis on the controls of fan geomorphology, sedimentology and dynamics. This provides a basis for integration between geomorphological and sedimentological approaches, and an understanding how fluvial systems respond to tectonic, climatic and base-level changes.

Download or read book Geology and Geomorphology of Alluvial and Fluvial Fans written by D. Ventra and published by Geological Society of London. This book was released on 2018-07-04 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alluvial and fluvial fans are the most widespread depositional landform bordering the margins of highland regions and actively subsiding continental basins, across a broad spectrum of tectonic and climatic settings. They are significant to the local morphodynamics of mountain regions and also to the evolution of sediment-routing systems, affecting the propagation and preservation of stratigraphic signals of environmental change over vast areas. The volume presents case studies discussing the geology and geomorphology of alluvial and fluvial fans from both active systems and ancient ones preserved in the stratigraphic record. It brings together case studies from a range of continents, climatic and tectonic settings, some introducing innovative monitoring and analysis techniques, and it provides an overview of current debates in the field. This volume will be of particular interest to geologists, geomorphologists, sedimentologists and the general reader with an interest in Earth science.

Download or read book Hydraulic Processes on Alluvial Fans written by R.H. French and published by Elsevier. This book was released on 1987-06-01 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alluvial fans are among the most prominent landscape features in the American Southwest and throughout the semi-arid and arid regions of the world. The importance of developing a qualitative and quantitative understanding of the hydraulic processes which formed, and which continue to modify, these features derives from their rapid and significant development over the past four decades. As unplanned urban sprawl has moved from valley floors onto alluvial fans, the serious damage incurred from infrequent flow events has dramatically increased.This book presents a concise, coherent discussion of our current and rapidly expanding knowledge of hydraulic processes on alluvial fans. It addresses the subject from a multidisciplinary viewpoint, acquainting the geologist with engineering principles, and the civil engineer and planner with geological principles pertinent to the analysis of hydraulic processes on alluvial fans. The book thus provides much of interest to geologists, civil engineers and planners involved in floodplain management and drainage design in arid and semi-arid regions.
