Sedimentary Structures and Their Relation to Bedforms and Flow Conditions


Book Description

Sedimentary structures that show up in outcrops and cores tell us about physical, biological and sometimes also chemical conditions at the time they were formed. Varying hydraulic or aerodynamic conditions result in assemblages of structures that often bear diagnostic features of sedimentary environments. Therefore an understanding of the origin of sedimentary structures and their assemblages is a prerequisite for sedimentologists and petroleum geologists involved in core description and interpretation. The main objective of this book is to bring together the present basic knowledge on the relation between sedimentary structures, bedforms and hydraulic conditions. The book is part of post-graduate Short Courses in Advanced Sedimentology and Stratigraphy for the petroleum industry offered by ENRES International. In these courses much attention is given to the recognition of sedimentary environments from diagnostic features of sedimentary structures and assemblages of structures. For this purpose practicals are given using a selection of lacquer peels and cores representing typical fluvial to estuarine, coastal and eolian environments. This material including its interpretation is published as a regularly updated stand-alone document that can be obtained from ENRES. One of the pioneering publications on this subject was a series of SEPM symposium papers published in 1965 (Middleton, 1965b). A more comprehensive publication on sediment movement by fluid flow and the resulting sedimentary structures was followed in 1972 (Blatt, Middleton and Murray, 1972). After that many excellent publications and textbooks were published (e.g. Allen, 1984, 1985; Bridge and Demicco, 2008; Collinson and Thompson, 1989; Harms et al., 1982; Hs?, 1989; Leeder, 1999; Reineck and Singh, 1980). These publications are partly covering a much wider scope as presented in this book, but are at some points not going into the desired details and are partly outdated. We have no intention to offer a new comprehensive textbook. The main goal of this book is to introduce the terminology and fundamental concepts that are necessary for the description and interpretation of the hydraulic background of sedimentary structures in siliciclastic deposits. Another objective of this book is to put this topic within the newly developed framework of modern stratigraphy (e.g. sequence stratigraphy and climate stratigraphy). Also some important new insights from recent research at the University of Utrecht and unique data of sedimentary structures from outcrops up to 15m below mean sea level have been added. A specially-designed Core Simulation software has been developed in cooperation with Statoil which will be used during the course and the practicals. Bron: Flaptekst, uitgeversinformatie.







Treatise on Geomorphology


Book Description

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!













River Dynamics


Book Description

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.
