Available in PDF, EPUB and Kindle. Book excerpt: Using numerical simulations of meandering rivers and adjacent sediments, I develop new length, velocity, and time scales based on planform dynamics of meandering rivers, allowing researchers to estimate the storage time of sediments in the absence of simulation or geochronologic measurements. I derive an equation which fits the sediment storage time distribution remarkably well and combines aspects of an exponential distribution with a truncated Pareto distribution. The truncation of the Pareto distribution is obscured if the oldest few percent of sediments are omitted. Storage time distributions have heavier tails in wider valleys. Storage time distributions are not at steady state: a) because the timescale to reach steady state in a broad floodplain exceeds the land use or climate timescale of constant external forcing, and b) due to heterogeneity in alluvial deposit ages and removal, even in a simulation under constant forcing conditions. Median storage times range from 330 to 750 years with an average of 497 years, while mean storage times (residence times) range from 540 to 20,300 years with an average of 2,490 years. 'Flood' deposits (deposited on top of point bars) are stored 1.2-2x longer than point bar deposits. The highest fraction (5.7%) of eroding point bar sediment has been stored for 90 years which is how long it takes for the channel to migrate 2.5 channel widths. There is significant variability in storage time distributions: Correlations between the median storage times decreases quickly through time, for distributions 180 years apart R2 is only 0.5. Most of the time, the oldest eroding sediment is younger than 10 kyr; occasionally, 20% of eroding sediment is older than 25 kyr. Flood deposits have less variability and preserve significantly more temporal signal than point bar deposits, but older deposits of both types are rarely included in the 'sampled' eroding sediment. Visually apparent patterns in the graphical presentation of the distributions suggest that variability is occurring at longer time scales than individual bend dynamics. Storage time distributions of sediment eroded today are poor estimates for the eventual storage time distribution of sediment deposited today.

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.

This book was released on 2019-01-22 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sinuous form and peculiar evolution of meandering rivers has long captured the imagination of people. Today, meandering rivers exist in some of the most densely populated areas in the World, where they provide environmental and economic wealth and opportunities, as well as posing hazards. Through geological time, the ancestors of these modern meanders built deposits that are now host to mineral resources, groundwater, and hydrocarbons. This Special Publication illustrates the breadth of current research on meandering rivers and their deposits. The collection of research papers demonstrates the state of science on fluvial process–product relationships. The articles cover fundamental and applied studies of both modern and ancient rivers, are based on state-of-the-art technology, include complementary philosophical approaches, and span a wide range of spatial and temporal scales. This book includes some of the most recent advances in the study of the morphodynamics and sedimentology of meandering rivers, and is an important resource for those who want to investigate fluvial systems and their deposits.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 194. Stream Restoration in Dynamic Fluvial Systems: Scientific Approaches, Analyses, and Tools brings together leading contributors in stream restoration science to provide comprehensive consideration of process-based approaches, tools, and applications of techniques useful for the implementation of sustainable restoration strategies. Stream restoration is a catchall term for modifications to streams and adjacent riparian zones undertaken to improve geomorphic and/or ecologic function, structure, and integrity of river corridors, and it has become a multibillion dollar industry. A vigorous debate currently exists in research and professional communities regarding the approaches, applications, and tools most effective in designing, implementing, and assessing stream restoration strategies given a multitude of goals, objectives, stakeholders, and boundary conditions. More importantly, stream restoration as a research-oriented academic discipline is, at present, lagging stream restoration as a rapidly evolving, practitioner-centric endeavor. The volume addresses these main areas: concepts in stream restoration, river mechanics and the use of hydraulic structures, modeling in restoration design, ecology, ecologic indices, and habitat, geomorphic approaches to stream and watershed management, and sediment considerations in stream restoration. Stream Restoration in Dynamic Fluvial Systems will appeal to scholars, professionals, and government agency and institute researchers involved in examining river flow processes, river channel changes and improvements, watershed processes, and landscape systematics.

Book excerpt: The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field. A host of noted international geomorphologists have contributed state-of-the-art chapters to the work. Readers can be guaranteed that every chapter in this extensive work has been critically reviewed for consistency and accuracy by the World expert Volume Editors and by the Editor-in-Chief himself No other reference work exists in the area of Geomorphology that offers the breadth and depth of information contained in this 14-volume masterpiece. From the foundations and history of geomorphology through to geomorphological innovations and computer modelling, and the past and future states of landform science, no "stone" has been left unturned!

This book was released on 2018 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment transport in rivers plays multiple key roles within every watershed. Fine sediments transported by rivers carry with them vital nutrients that are essential to riverine and estuarine life, when not in excess. Floodplain storage of these same fine sediments is of interest to parties attempting to mitigate downstream sediment and nutrient pollution. However, historic methodological and technological limitations have limited fine-scale studies of floodplain storage. This exploratory study, utilizing modern multi-temporal high-resolution topography and advanced geospatial analysis tools, sought to overcome these limitations and comprehensively assess floodplain sediment dynamics and the conditions governing them. Our findings suggest that in addition to geometric measures, flow conditions across a floodplain during the falling limb are strong predictors of floodplain-scale sedimentology. Further results suggest modern high-resolution topography is capable of adequately modeling fine-scale sediment dynamics from single storms, accurately characterizing low-relief landforms, and providing detailed terrains for hydraulic models.
