Book Synopsis Fine Sediment Dynamics in the Marine Environment by : Johan C. Winterwerp
Download or read book Fine Sediment Dynamics in the Marine Environment written by Johan C. Winterwerp and published by Elsevier. This book was released on 2002-06-05 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cohesive sediment, or mud, is encountered in most water bodies throughout the world. Often mud is a valuable resource, synonymous with fertile land, enriching the natural environment and used as an important building material. Yet mud also hinders navigation and consequently, dredging operations have been carried out since ancient times to safeguard navigation. Unfortunately, many mud deposits are now contaminated, endangering the eco-system and increasing the costs of dredging operations. The transport and fate of mud in the environment are still poorly understood and the need for basic research remains. This text contains the proceedings of the INTERCOH-2000 conference on progress in cohesive sediment research. It was the sixth in a series of conferences initially started by Professor Ashish Mehta in 1984 as a "Workshop on Cohesive Sediment Dynamics with Special Reference to the Processes in Estuaries". During these conferences the character of the first workshop has always been maintained, that is, small scale and dedicated to the physical and engineering aspects of cohesive sediments, without parallel sessions, but with ample time for discussions during and after the presentations, and followed by a book of proceedings containing thoroughly reviewed papers. INTERCOH-2000 was integrated with the final workshop of the COSINUS project. This project was carried out as a part of the European MAST-3 programme, and almost all European cohesive sediment workers were involved. INTERCOH-2000 focused on the behaviour and modelling of concentrated benthic suspensions, i.e. high-concentrated near-bed suspensions of cohesive sediment. Special attention was paid to: sediment - turbulence interaction; flocculation and settling velocity; high-concentrated mud suspensions; processes in the bed - consolidation; processes on the bed - erosion; field observations on mud dynamics; instrumentation; and numerical modelling.

Book Synopsis Fine Sediment In Open Water: From Fundamentals To Modeling by : Johan C Winterwerp
Download or read book Fine Sediment In Open Water: From Fundamentals To Modeling written by Johan C Winterwerp and published by World Scientific. This book was released on 2021-11-08 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fine Sediment in Open Water is mainly written for professional engineers working in estuaries and coastal systems. It provides the basis for a fundamental understanding of the physical, biological and chemical processes governing the transport and fate of fine sediment in open water and explains how this understanding can steer engineering studies with numerical models. This is a unique treatment of processes at a variety of spatial and temporal scales, from the micro-scale (colloid scale) to system-wide scales, and from intra-tidal time periods to decades.Beginning with the processes governing the transport and fate of fine sediment in shallow open water, the first eight chapters are dedicated to the hydrodynamic, soil mechanics and biological processes which determine fine sediment concentrations in the water column, in/on the bed and the exchange of sediment between bed and water column. The next two chapters treat the net fluxes of fine sediment as a function of asymmetries in forcing and sediment properties. These fundamental processes form the basis for the subsequent chapters on modeling in which the governing equations are presented, and tools are provided to aggregate and parameterize the various processes elaborated in the first eight chapters. Further, any numerical model study should be based on a conceptual model, as illustrated in the final five chapters, which provide examples of numerical modeling studies on the transport and fate of fine sediment in a coastal sea, an estuary, a tidal river, a lake, and around and within a harbor basin.Related Link(s)
Book Synopsis Introduction to the Physics of Cohesive Sediment Dynamics in the Marine Environment by : Johan C. Winterwerp
Download or read book Introduction to the Physics of Cohesive Sediment Dynamics in the Marine Environment written by Johan C. Winterwerp and published by Elsevier. This book was released on 2004-08-20 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to the physical processes of cohesive sediment in the marine environment. It focuses on highly dynamic systems, such as estuaries and coastal seas. Processes on the continental shelf are also discussed and attention is given to the effects of chemistry, biology and gas.The process descriptions are based on hydrodynamic and soil mechanic principles, which integrate at the soil-water interface. This approach is substantiated through a classification scheme of sediment occurrences in which distinction is made between cohesive and granular material. Emphasis is also placed on the important interactions between turbulent flow and cohesive sediment suspensions, and on the impact of flow-induced forces on the stability of the seabed. An overview of literature on cohesive sediment dynamics is presented and a number of new developments are highlighted, in particular in relation to floc formation, settling and sedimentation, consolidation, bed failure and liquefaction and erosion of the bed. Moreover, it presents a summary on methods and techniques to measure the various sediment properties necessary to quantify the various parameters in the physical-mathematical model descriptions. A number of examples and case studies have been included.
Book Synopsis An Introduction To Hydraulics Of Fine Sediment Transport by : Ashish J Mehta
Download or read book An Introduction To Hydraulics Of Fine Sediment Transport written by Ashish J Mehta and published by World Scientific Publishing Company. This book was released on 2013-09-30 with total page 1060 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents observations on the phenomena of fine sediment transport and their explanations under process-related divisions such as flocculation, erosion, and deposition.The text is a compilation of the author's lecture notes from nearly four decades of teaching and guiding graduate students in civil and coastal engineering. Illustrations of fine sediment transport processes and their complexities given in the book are taken from field and laboratory-based observations by the author and his students, as well as numerous investigators.The wide-ranging composition of particles (of inorganic and organic matter), their universal presence and their complex interactions with hydraulic forces make this branch of science a difficult one to deal with in a single treatise. It is therefore essential to study fine sediment transport as an independent subject rather than cover it in no more than a single chapter as many texts on coarse sediment transport have done.Even though the entire coverage is “introductory”, the twelve chapters collectively include more material than what can be reasonably dealt with in a one semester, three-credit course.The book includes an extensive description of the components of fine-grained — especially cohesive — sediment transport. It covers the development of the subject in scientific and engineering applications mainly from the 1950s to its present state. Solved examples and chapter-end exercises are also included.This text is aimed at senior civil engineering undergraduates and graduate students who, in the normal course of their study, seldom come across the subject of fine sediment transport in their curricula. Interested students should have a basic understanding of the mechanics of fluid flow and open channel hydraulics.
Book Synopsis Riverine Ecosystem Management by : Stefan Schmutz
Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Book Synopsis Sediment Transport by : Andrew Manning
Download or read book Sediment Transport written by Andrew Manning and published by BoD – Books on Demand. This book was released on 2013-03-13 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment Transport Processes and their Modelling Applications is a book which covers a wide range of topics. The effective management of many aquatic environments, requires a detailed understanding of sediment dynamics. This has both environmental and economic implications, especially where there is any anthropogenic involvement. Numerical models are often the tool used for predicting the transport and fate of sediment movement in these situations, as they can estimate the various spatial and temporal fluxes. However, the physical sedimentary processes can vary quite considerably depending upon whether the local sediments are fully cohesive, non-cohesive, or a mixture of both types. For this reason for more than half a century, scientists, engineers, hydrologists and mathematicians have all been continuing to conduct research into the many aspects which influence sediment transport. These issues range from processes such as scour, erosion and deposition, to how sediment process observations can be applied in sediment transport modelling frameworks. This book reports the findings from recent research in applied sediment transport which has been conducted in a wide range of aquatic environments. The research was carried out by researchers who specialise in the transport of sediments and related issues.
Book Synopsis Introduction To Hydraulics Of Fine Sediment Transport, An (Second Edition) by : Ashish J Mehta
Download or read book Introduction To Hydraulics Of Fine Sediment Transport, An (Second Edition) written by Ashish J Mehta and published by World Scientific. This book was released on 2022-11-22 with total page 1054 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book expounds the hydraulics of fine sediment which is almost ubiquitously found in coastal and estuarine waters, and in rivers, lakes, and reservoirs. Although the basic subject may be categorized as applied marine physics in shallow waters, several physicochemical and biological effects on particulate transport have been addressed.In this second edition most of the chapters have been substantially updated, rewritten, and expanded. Overall, a significant change has also been made throughout by replacing sediment concentration, a unit dependent quantity at the heart of numerous descriptions, measurements, and calculations, with the nondimensional sediment volume fraction. It marks a divergence in the manner in which fine sediment transport data and calculations are conventionally presented.The book is mainly written for civil engineering seniors and graduate students, to offer a comprehensive foundation in hydraulics of fine sediment. The book is also a useful reference for researchers interested in the effects of physical chemistry and biology on fine sediment transport in water and to an extent on coastal and estuarine morphodynamics, sediment transport, port and harbor engineering, and applied shallow watwer marine physics. The book is also recommended reading for those interested in understanding particle transport in water.Related Link(s)
Book Synopsis Sedimentation and Sediment Transport by : A. Gyr
Download or read book Sedimentation and Sediment Transport written by A. Gyr and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is evident, that for a number of ecological and technical problems in rivers and lakes a better knowledge of sediment transport and sedimentation is needed together with the ability to predict and simulate sediment behaviour. On the other hand, a stagnation of research in these topics could be observed in the last decades. At the Symposium an attempt was made to present new results in mathematics and natural sciences relevant for the sediment problem. New strategies were discussed to tackle the complexity of the problem. Basic theoretical research and laboratory experiments alone are incomplete without a feedback from field observations and measurements. For that reason well-known researchers from both basic and engineering sciences were invited. Turbulence, non-local phenomena, stability, interaction, feedback systems, self-organization, two-phase flow and chaotic processes, numerical simulations as well as measurement techniques and field results were the keywords of the Symposium. This proceedings are a good source for those interested in the state of the art.
Book Synopsis Sediment Transport Research - Further Recent Advances by : Andrew J. Manning
Download or read book Sediment Transport Research - Further Recent Advances written by Andrew J. Manning and published by BoD – Books on Demand. This book was released on 2024-08-21 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effective governance and administration of many aquatic and terrestrial environments requires a detailed understanding of sediment transport and its behavioral dynamics. This has both environmental and economic implications, especially where there is any anthropogenic involvement. Sedimentary processes such as erosion, scour, deposition, and consolidation can fluctuate depending on whether their compositional matrix is purely cohesive, noncohesive, or a combination of both types. With many contributing factors, the prediction of sedimentary movement is often made using numerical modeling tools, as they can estimate the various spatial and temporal fluxes. However, due to the complex behavior of natural sediments, scientists and other specialists continue to conduct research into the many aspects that influence sediment transport. Sediment Transport Research - Further Recent Advances is a book that draws on the most recent world-class scientific research on sediment transport topics, including computational fluid dynamics, numerical modeling, particle properties and characteristics, beach morphology, soil erosion, flocculation processes, sand nourishment, geomorphology, water quality aspects, sedimentary-related legislation, and many more. The research was carried out by researchers who specialize in sediment transport and related processes.

Book Synopsis Integration of Computer Modeling and Field Observations in Geomorphology by : J.F. Shroder
Download or read book Integration of Computer Modeling and Field Observations in Geomorphology written by J.F. Shroder and published by Gulf Professional Publishing. This book was released on 2003-09-26 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of classic field-gathered data with new computer models has allowed many new advances in geomorphology, which the 31st Binghamton Millennium Symposium 2000 presents in this latest of the well-known Binghamton book series, the Integration of Computer Modeling and Field Observations in Geomorphology. Conceptual models have been most commonly inferred from analyses of topography and investigator perspectives derived from fieldwork. The main stumbling blocks to understanding surface processes, their interactions, temporal changes, and resulting landforms are the difficulty of observation, geological timescales involved, spatial-scale dependencies, and the inability to attribute differences to either process or age. Physically based computer models have thus become essential tools, primarily because of their ability to explore spatial and temporal trends and to determine the sensitivity of physical inputs to change without the difficulties of identification and generalization associated with the complexity of field studies. Thus, the combination of both methods, or the integration of field methods with computer modeling become a very powerful mechanism for robust understanding. This new book presents topics on fluvial processes of overland and channelized flow in arid, humid, and periglacial areas of high and low relief, as well as work on interlinked biogeographic and geomorphic fluctuations in alpine terrain, and ground penetrating radar of coastal geomorphology. Issues of long-term evolution of drainage networks are addressed in natural systems, as well as stream-table environments, and terrain analyses characterize surficial and subsurface geomorphic features by using GIS and remote sensing. Botanical and biogeomorphologic controls of landforms are assessed, along with issues of scientific visualization, cartographic representation, DEMs, spatial analyses, and scale dependencies.
