Fluvial Hydraulics provides a sound qualitative and quantitative understanding of water and sediment flows in natural rivers. This understanding is essential for modeling and predicting hydrologic and geomorphologic processes, erosion, sediment transport, water supply and quality, habitat management, and flood hazards. This book's coverage bridges the gap between the highly quantitative mechanics-based civil-engineering approach to stream hydraulics and the more qualitative treatments of fluvial geomorphology typical of earth-sciences and natural-resources curricula. Measurements of natural river flows illustrate many central concepts.
The book is specifically designed for upper-level students and practitioners who are interested in a fundamental understanding of river behavior. An introduction to the history of fluvial hydraulics and an overview of the morphology and hydrology of rivers provides the context for the rest of the text. A thorough understanding of water properties, including turbulence, is developed via a series of simple thought experiments. The bases of the equations that are used to describe and predict river flows are systematically presented, including dimensional analysis. Subsequent chapters build logically on these foundations, covering velocity distributions, new insights to the central topic of flow resistance, the magnitudes of forces in natural river flows, the principles of conservation of energy and momentum, the prediction of water-surface profiles, the principles of flow measurement, mechanics, and geomorphic aspects of sediment transport. The book will be especially valuable in providing a scientific basis for the growing field of river restoration.
An appendix reviews dimenstions, units, and numerical precision. Over 250 references are cited, providing an entree to the extensive multi-disciplinary literature on rivers. The book's website provides suggestions for student exercises and makes available extensive data bases of measured streamflows for student exploration.

The content focuses not only on inorganic constituents but also on natural and anthropogenic organic chemicals in water. This new edition of Water Chemistry also features updated discussions of photochemistry, chlorine and disinfectants, geochemical controls on chemical composition, trace metals, nutrients, and oxygen. Quantitative equilibrium and kinetic problems related to acid-base chemistry, complexation, solubility, oxidation/reduction reactions, sorption, and the fate and reactions of organic chemicals are solved using mathematical, graphical, and computational tools. Examples show the application of theory and demonstrate how to solve problems using algebraic, graphical, and up-to-date computer-based techniques. Additional web material provides advanced content.

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.

Mathematical modeling and numerical simulation in fluid mechanics are topics of great importance both in theory and technical applications. The present book attempts to describe the current status in various areas of research. The 10 chapters, mostly survey articles, are written by internationally renowned specialists and offer a range of approaches to and views of the essential questions and problems. In particular, the theories of incompressible and compressible Navier-Stokes equations are considered, as well as stability theory and numerical methods in fluid mechanics. Although the book is primarily written for researchers in the field, it will also serve as a valuable source of information to graduate students.

This title includes a number of Open Access chapters. Hydraulic fracturing, or "fracking" as it is commonly known, refers to the practice of using liquids at very high pressures to fragment rock, thereby allowing natural gas to be harvested. This process increases energy resources but also has some negative environmental impacts as well. This book looks at the environmental impact. The first section looks at fracturing and the water supply, the second section looks at ecosystems and wildlife, while the final section examines the possible effects on human ecosystems and human health.

Large-Eddy Simulation (LES), which is an advanced eddy-resolving method for calculating turbulent flows, is used increasingly in Computational Fluid Dynamics, also for solving hydraulics and environmental flow problems. The method has generally great potential and is particularly suited for problems dominated by large-scale turbulent structures. This book gives an introduction to the LES method specially geared for hydraulic and environmental engineers. Compared with existing books on LES it is less theoretically and mathematically demanding and hence easier to follow, and it covers special features of flows in water bodies and summarizes the experience gained with LES for calculating such flows. The book was written primarily as an introduction to LES for hydraulic and environmental engineers, but it will also be very useful as an entry to the subject of LES for researchers and students in all fi elds of fl uids engineering. The applications part will further be useful to researchers interested in the physics of fl ows governed by the dynamics of coherent structures.

This book has been documented with the aim to include those fundamentals of 'Hydraulic Machines' which are necessary at graduate level engineering courses of any University. Basic hydraulics is extensively used in various applications in industry, construction, mining and marine engineering. The subject is part of graduate level engineering courses in mechanical, civil, mining, and marine engineering studies worldwide. Most of the literature, however, is either written with a commercial objective to promote the sale of the manufacturers or is theoretically too advanced for comprehension by graduate level engineering students. The rapid advancement in design, miniaturization, metallurgy, and hydraulic fluid characteristics has stimulated the demand for an elementary book, explaining fundamentals. Readers are supposed to be familiar with the elementary fluid mechanics, and basics of gears, piston, crank, and different levers. This book includes those fundamentals of fluid transmission of power that are necessary in graduate mechanical engineering, civil engineering, mining engineering, and marine engineering courses of any university.

Throughout the world, boreholes and tubewells operate inefficiently or have been abandoned. Diagnosis of the problems requires hydrogeological and operational information, which is often not available because appropriate monitoring has not taken place. Guidelines on cost effective monitoring and maintenance need to be established; information on successful rehabilitation techniques is needed. This book forms the proceedings of a conference organised to exchange practical experience and scientific knowledge on these aspects of water wells.

This book provides comprehensive guidance on maintaining old waterfront structures, particularly gravity walls constructed with stone masonry, brick, blocks or mass concrete. It will be valuable for all engineers responsible for such structures.

The first of its kind, this book is an in-depth history of hydrodynamics from its eighteenth-century foundations to its first major successes in twentieth-century hydraulics and aeronautics. It documents the foundational role of fluid mechanics in developing a new mathematical physics. It gives full and clear accounts of the conceptual breakthroughs of physicists and engineers who tried to meet challenges in the practical worlds of hydraulics, navigation, blood circulation, meteorology, and aeronautics, and it shows how hydrodynamics at last began to fulfill its early promise to unify the different worlds of flow. Richly illustrated, technically thorough, and sensitive to cross-cultural effects, this history should attract a broad range of historians, scientists, engineers, and philosophers and be a standard reference for anyone interested in fluid mechanics.
