Sediment Transport Technology


Book Description




Sediment Transport


Book Description

This book provides a broad perspective of sediment transport in rivers, reservoirs, estuaries, and coastal areas. It deals with the related fundamentals of sediment transport, computational modelling of cohesive and non-cohesive sediments transport, and sedimentation engineering management. Topics include river morphological changes after dam removal, local scour and its monitoring, marsh edge erosion, turbidity dynamics in a bay surrounded by marshes, effects of harbour construction on hydrodynamic and morphodynamic processes in a coastal area, and impact of climate change on sediment yield from a watershed, are discussed. The breath of the topics covered will be of interest to researchers and practising engineers alike. This book contains twelve chapters.




Sediment Transport


Book Description

Sediment transport is a book that covers a wide variety of subject matters. It combines the personal and professional experience of the authors on solid particles transport and related problems, whose expertise is focused in aqueous systems and in laboratory flumes. This includes a series of chapters on hydrodynamics and their relationship with sediment transport and morphological development. The different contributions deal with issues such as the sediment transport modeling; sediment dynamics in stream confluence or river diversion, in meandering channels, at interconnected tidal channels system; changes in sediment transport under fine materials, cohesive materials and ice cover; environmental remediation of contaminated fine sediments. This is an invaluable interdisciplinary textbook and an important contribution to the sediment transport field. I strongly recommend this textbook to those in charge of conducting research on engineering issues or wishing to deal with equally important scientific problems.




Fluvial Sediment Transport


Book Description

Provides guidance on selected techniques for the measurement of particles moving in the fluvial environment. The potential user is directed in the selection of an appropriate technique through the presentation of operating principles, application guidelines and estimated costs.




Coastal Bottom Boundary Layers And Sediment Transport


Book Description

This book is intended as a useful handbook for professionals and researchers in the areas of Physical Oceanography, Marine Geology, Coastal Geomorphology and Coastal Engineering and as a text for graduate students in these fields. With its emphasis on boundary layer flow and basic sediment transport modelling, it is meant to help fill the gap between general hydrodynamic texts and descriptive texts on marine and coastal sedimentary processes. The book commences with a review of coastal bottom boundary layer flows including the boundary layer interaction between waves and steady currents. The concept of eddy viscosity for these flows is discussed in depth because of its relation to sediment diffusivity. The quasi-steady processes of sediment transport over flat beds are discussed. Small scale coastal bedforms and the corresponding hydraulic roughness are described. The motion of suspended sand particles is studied in detail with emphasis on the possible suspension maintaining mechanisms in coastal flows. Sediment pickup functions are provided for unsteady flows. A new combined convection-diffusion model is provided for suspended sediment distributions. Different methods of sediment transport model building are presented together with some classical models.




Hydraulics of Sediment Transport


Book Description

This book is divided into four parts: Part 1 is entitled "A Short History of Sediment Transport"; Part 2 deals with the "Hydrodynamics of Fluid-Particle Systems"; Part 3 is concerned with the "Sediment Transport in Open Channels"; and Part 4 describes the "Sediment Transport in Closed Pipes." The intent of this book was to make each part as self-contained as possible which has made this an exceptional and successful textbook. The brief introduction preceding each part will help the reader become familiar with the topic. This book has been used successfully both as a classroom textbook and as a reference book by consultants involved with sediment transport.







Estuarine and Coastal Hydrography and Sediment Transport


Book Description

A practical guide to the latest techniques to measure sediments, seabed, water and transport mechanisms in estuaries and coastal waters. Covering a broad range of topics, enough background is included to explain how each technology functions. A review of recent fieldwork experiments demonstrates how modern methods apply in real-life scenarios.




Fluvial Hydrodynamics


Book Description

The state-of-the-art in fluvial hydrodynamics can be examined only through a careful exploration of the theoretical development and applied engineering technology. The book is primarily focused, since most up-to-date research findings in the field are presented, on the research aspects that involve a comprehensive knowledge of sediment dynamics in turbulent flows. It begins with the fundamentals of hydrodynamics and particle motion followed by turbulence characteristics related to sediment motion. Then, the sediment dynamics is analysed from a classical perspective by applying the mean bed shear approach and additionally incorporating a statistical description for the role of turbulence. The work finally examines the local scour problems at hydraulic structures and scale models. It is intended to design as a course textbook in graduate / research level and a guide for the field engineers as well, keeping up with modern technological developments. Therefore, as a simple prerequisite, the background of the readers should have a basic knowledge in hydraulics in undergraduate level and an understanding of fundamentals of calculus.




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.
