Fine Sediment In Open Water From Fundamentals To Modeling

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)

The World of Discovery Collection is a specially curated selection of children's books that focus on discovering Asia and discovering STEM (Science, Technology, Engineering and Maths). Under the guidance of Dr Ruth Y L Wong, these books aim to promote reading for pleasure, while exciting kids through discovery. With 51 books in this inaugural batch, and with more to come, the books are divided into three levels depending on the child's reading ability: A (Achieving), B (Blooming) and C (Confident). Level B Set 2 features nine titles, exploring themes of science, imagination, nature and global stories. Intended outcomes of Level B include teaching children to be able to: - follow a text when it is being read aloud - turn the page at the right time - sound out at least 70% of the words in the book - read simple sentences - enjoy being read to Each book includes a story-based activity at the end of the books to help parents and educators get children to engage with the story.

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)

This monograph aims at presenting a unified approach to numerical modeling of tsunami as long waves based on finite difference methods for 1D, 2D and 3D generation processes, propagation, and runup. Many practical examples give insight into the relationship between long wave physics and numerical solutions and allow readers to quickly pursue and develop specific topics in greater depth. The aim of this book is to start from basics and then continue into applications. This approach should serve well the needs of researchers and students of physics, physical oceanography, ocean/civil engineers, computer science, and emergency management staff. Chapter 2 is particularly valuable as it fully describes the application of finite-difference methods to the study of long waves by demonstrating how physical properties of water waves, especially phase velocity, are connected to the chosen numerical algorithm. Basic notions of numerical methods, i.e. approximation of the relevant differential equations, stability of the numerical scheme, and computational errors are explained through application to long waves. Finite-difference methods are further developed in major chapters to deal with complex problems that arise in the study of recent tsunamis.

Coastlines, like many things around us, are constantly evolving. Keeping pace with the changes and their development is necessary to ensure their stability and to maintain eco-equilibrium for nearshore hydrodynamics and morphodynamics. Supported with field measurements for model validation, several numerical and analytical tools are available to us to understand the physical processes in the vicinity of these water bodies.This book encompasses the engineering principles involved in field data observation, measurement, collection, and processing; the prediction of wave climate and sediment transport using measured field data; numerical modelling involving calibration and validation of the hydrodynamic and morphodynamic processes; and the study of the underlying physical processes and the application of sustainable engineering measures to combat coast- and estuary-related problems.The book has three sections: The first section is an elaboration on the need for and framework of the existing management and engineering notions. The second section details the measurement of the various parameters such as wave climate (offshore and nearshore), shoreline changes, beach profile variation, and sediment transport rates. The third section describes the aspects of wave prediction to arrive at design characteristics and modelling of the hydrodynamic and morphodynamic processes along open coasts and tidal inlets.This book is designed to benefit students pursuing coastal engineering as their field of specialization. It could also serve as a guidebook to engineers, planners, and decision makers working in the fields of coastal, estuarine, and harbour engineering, governmental and private agencies that plan the financial outlay for coastal development projects, and private consultants dealing with maritime hydraulics.

Shallow water acoustics (SWA), the study of how low and medium frequency sound propagates and scatters on the continental shelves of the worlds oceans, has both technical interest and a large number of practical applications. Technically, shallow water poses an interesting medium for the study of acoustic scattering, inverse theory, and propagation physics in a complicated oceanic waveguide. Practically, shallow water acoustics has interest for geophysical exploration, marine mammal studies, and naval applications. Additionally, one notes the very interdisciplinary nature of shallow water acoustics, including acoustical physics, physical oceanography, marine geology, and marine biology. In this specialized volume the authors, all of whom have extensive at-sea experience in US and Russian research efforts, have tried to summarize the main experimental, theoretical, and computational results in shallow water acoustics, with an emphasis on providing physical insight into the topics presented.
