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.
Download or read book Turbulence and Flow Sediment Interactions in Open Channel Flows written by Roberto Gaudio and published by MDPI. This book was released on 2021-06-04 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main focus of this Special Issue of Water is the state-of-the-art and recent research on turbulence and flow–sediment interactions in open-channel flows. Our knowledge of river hydraulics is deepening, thanks to both laboratory/field experiments related to the characteristics of turbulence and their link to erosion, transport, deposition, and local scouring phenomena. Collaboration among engineers, physicists, and other experts is increasing and furnishing new inter-/multidisciplinary perspectives to the research of river hydraulics and fluid mechanics. At the same time, the development of both sophisticated laboratory instrumentation and computing skills is giving rise to excellent experimental–numerical comparative studies. Thus, this Special Issue, with ten papers by researchers from many institutions around the world, aims at offering a modern panoramic view on all the above aspects to the vast audience of river researchers.
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.
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)

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)

Download or read book Geology for Nongeologists written by Frank R. Spellman and published by Government Institutes. This book was released on 2009-07-16 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geology for Nongeologists introduces basic concepts in geology: how rocks, minerals, and fossils are classified, how wind, ice, and water have shaped the earth, how mountains are formed, and how volcanoes, geysers, earthquakes, glaciers, and groundwater work to modify the physical structure of Earth. Primarily designed as an information source, and intended to be a non-technical survey for those with little background in science, this book is presented in a reader-friendly style. Written in straightforward and accessible English, this book provides a broad look at a multidisciplinary field that incorporates aspects of biology, chemistry, physics, ecology, geography, meteorology, pedology, and many other areas of science. This book fills the gap between general introductory science texts and advanced environmental science books. Books on the subject are typically geared toward professionals in these fields. This makes undertaking a study of geology daunting to those without a specific background in science. However, this complexity also indicates geology's broad impact. Because geology so widely affects us, sometimes in profound ways, it is important to understand its basic concepts. This book presents information that everyone needs to know about geology and about how science and scientists work. The author uses illustrative problems in terms of commonly used geological parameters, and each chapter ends with a chapter review test. Readers discover a new appreciation for their surroundings and a broader outlook on their environment.
