Available in PDF, EPUB and Kindle. Book excerpt: While floods have been widely studied, quantifying or predicting their impacts remains challenging for geomorphologists. Often the spatial or temporal scales of analysis prevent robust analytics: spatially, studies typically have been done on the cross section scale or temporally by comparing pre- to post-flood geospatial datasets. In this study, to capture the response and recovery process following a catastrophic flood generated by Tropical Storm Irene, we use high-resolution ({u2264}lm) lidar data from before the flood (2010), one year after the flood (2012), and four years after the flood (2015) to build a predictive model of erosion and deposition, as well as assess the changes in the variability of the channel's unit stream power curve, which we use as a proxy for reach-scale equilibrium. Findings suggest that the downstream gradient in unit stream power is a powerful predictor of erosion and deposition, but where the two-year flow exceeds 150 W/m2, erosion is the dominant response. The result of this is the reduction of variation in the unit stream power curve over the ~l km scale, which we argue to be a change in the direction of reach-scale equilibrium.

Book Synopsis An Investigation of the Geomorphology and Flooding Characteristics of a Small Stream in the Upper Big Walnut Creek Watershed, Ohio by : Beth Ellen Fry
Download or read book An Investigation of the Geomorphology and Flooding Characteristics of a Small Stream in the Upper Big Walnut Creek Watershed, Ohio written by Beth Ellen Fry and published by . This book was released on 2006 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The objectives pertaining of this study were to 1) characterize the geomorphology of the headwaters of Sugar Creek (a tributary of the Upper Big Walnut Creek), 2) evaluate methods for relating recurrence intervals to discharge on the ungaged stream, and 3) to determine the frequency and magnitude of annual out of bank discharge at various locations along the stream. The bankfull discharge characteristics of Sugar Creek were analyzed with a regional curve analysis; the Rosgen Classification System, and an analysis of the threshold particle size. The three methods for estimating recurrence interval discharges of ungaged streams included two uncalibrated landscape models and estimates calibrated with USGS data from a downstream gage. HEC-HMS and HECRAS modeling programs were used to develop discharge recurrence interval relationships for selected locations along Sugar Creek. The frequencies associated with recurrence interval discharges, in times per year, were estimated with a time duration analysis and the average annual volume of overbank flows, as a percent of the total flow, utilized a combination of the generated flow hydrographs and the frequencies associated with recurrence interval discharges. Sugar Creek was a stable system, or in dynamic equilibrium, and had an extensive floodplain with entrenchment ratios ranging from 2 to 18. A calibrated method for estimating recurrence interval discharges was selected and used to estimate the average annual frequency and volume of overbank flows. Among eight locations focused on in the study, 38% experienced bankfull or larger discharges an average of 12 times per year, with about a 0.2-year recurrence interval for the bankfiill discharge. Seventy-five percent of the locations experienced bankfull or larger discharges an average of at least 3 times per year, with about a 0.8-year recurrence interval. Eighty-eight percent the locations, experienced out of bank flows at least 1 time per year, with about a 1.6-year recurrence interval. All of the locations experienced out of bank flows an average of at least 1 time per year, with the 2-year recurrence interval discharge. Out of bank flows ranged from 0.4% to 13% of the average annual flow volume. Based on the results of this study, it was recommended that further research be conducted in the Sugar Creek watershed to quantify the water quality benefits within the floodplain, as well as the benefits of a stable stream.
Download or read book River Dynamics written by Bruce L. Rhoads and published by Cambridge University Press. This book was released on 2020-04-29 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.

Book Synopsis Alluvial Fan Flooding by : National Research Council
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.

Book excerpt: This is a discount Black and white version. Some images may be unclear, please see BCCampus website for the digital version.This book was born out of a 2014 meeting of earth science educators representing most of the universities and colleges in British Columbia, and nurtured by a widely shared frustration that many students are not thriving in courses because textbooks have become too expensive for them to buy. But the real inspiration comes from a fascination for the spectacular geology of western Canada and the many decades that the author spent exploring this region along with colleagues, students, family, and friends. My goal has been to provide an accessible and comprehensive guide to the important topics of geology, richly illustrated with examples from western Canada. Although this text is intended to complement a typical first-year course in physical geology, its contents could be applied to numerous other related courses.
Book Synopsis The Fluvial System by : Stanley Alfred Schumm
Download or read book The Fluvial System written by Stanley Alfred Schumm and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1977, this is a classic of the geomorphology literature. Erosion, transport, and deposition of sediment within river catchments concern a wide range of earth scientists and profoundly affect land management. Upland soil removal engages the attention of soil conservationists, hydraulic engineers deal with fluvial sediment transport and river channel morphology, and patterns of sediment deposition in riverine and coastal lowlands affect navigability, the habitability of valley floors and the distribution of groundwater and minerals. The author argues persuasively that fluvial geomorphology, sedimentology and stratigraphy provide insights into each of these components of the river basin. "This volume, with its generous illustrations will be welcomed by earth scientists generally. It fills an important niche in the fluvial literature and its lucid style and clear exposition place it well within the range of students in any form of higher education." Nature "As a synthesis of the fluvial system and its effects on the landscape, as a primer in fluvial geomorphology and sedimentation for the planner, engineer and economic geologist, and as a stimulator of geomorphic thought, this book is most valuable." American Scientist Dr. Schumm is an internationally recognized geomorphologist who has published 150 papers and authored and edited 11 books. His primary experience has been in the investigation and analysis of fluvial systems. He has applied the concepts of geomorphology, fluvial hydraulics and geology to analyze alluvial river form and shape, sediment transport and effects of man-induced changes on river systems throughout the United States and in numerous foreign countries. He has also been involved in the interpretation of lunar and Martian landforms. Dr. Schumm is a past Chairman of the Geopmorphology Division of the Geological Society of America, has served on technical and committees of the National Research Council, the Geological Society of America, the American Geophysical Union, International Geographic Union, the National Science Foundation and NASA. He has performed research, lectured and advised government agencies around the world.
