Principles Of River Hydraulics

This book presents key principles of the hydraulics of river basins, with a unique focus on the interplay between stream flows and sediment transport. Addressing a number of basic topics related to the hydraulics of natural waterways, it above all emphasizes applicative aspects in order to provide the reader with a solid grasp of river engineering. The first chapter explores many of the fixed base hydraulic topics that are normally neglected in traditional texts, namely the effects on motion produced by the vegetation and macroroughnesses that characterize many mountain streams. The remaining chapters are devoted entirely to hydraulics with mobile riverbeds and put particular emphasis on inhomogeneous river channels. The book’s approach goes beyond classical treatments, so as to not only introduce readers to the fundamentals of mobile riverbeds, but also enable today’s river engineers to successfully design and maintain natural riverbeds.

This book presents key principles of the hydraulics of river basins, with a unique focus on the interplay between stream flows and sediment transport. Addressing a number of basic topics related to the hydraulics of river systems, above all it emphasizes applicative aspects in order to provide the reader with a solid grasp of river engineering. The understanding of the river hydraulics is essential for the assessment of optimum locations for the conservation of water resources and its structures. This book will be interesting to readers and researchers working in the specialized area of river hydraulics of Ganga basin, Narmada, Tapi, Godavari, and other basins of India. It consists of review on hydraulics of meandering river; hydraulic design of reservoir in permeable pavement; optimization of hydraulic design; hydraulic investigations to optimize the design of spillway and design of energy dissipater; and analysis of performance of orifice spillway using computational fluid dynaics

In this volume, the fundamental principles and applications of river engineering are presented and the close interrelation between river engineering and fluvial processes is stressed. The author integrates river engineering principles with river hydraulics and fluvial geomorphology, providing engineers interested in water supply, channel design, bridge design, flood control, river regulation, irrigation, navigation improvement, and environmental science with a comprehensive, system perspective. Specific topics covered include river flow, river channel formation, the physical characteristics of rivers, responses of rivers to natural and man-made changes, and analytical methods of design and evaluation.

Excerpt from The Hydraulic Principles Governing River and Harbor Construction During his professional career the writer has prepared numerous projects, and has answered many criticisms of the methods employed in the improvement of rivers and harbors. The following pages are derived principally from these sources. In replying to complainants, the author came to the conclusion that there was a commendable interest among the American people in the subject of the improvement of rivers and harbors, and a deplorable ignorance of the fundamental principles governing the flow of water in natural channels. Such is his apology for this publication. The ordinary textbook on hydraulics treats principally of the flow of water in pipes and conduits, and the ordinary engineer is apt to consider a river as merely a large conduit governed by the same laws, ignoring the change in conditions arising from the fact that the walls of a pipe are not affected by the velocity of flow through it, while the channels of a silt-bearing stream expand or contract with every change in the volume of discharge. This fact is ignored also by many writers on river hydraulics, whose textbooks contain more or less elaborate discussions of the formulas which are authoritatively stated as guides for determining the depth in a contracted waterway. In a rock cut, these formulas give as accurate results as they do when applied to a sewer or to a pipe, but in the alluvium of the Mississippi or Missouri rivers, scour caused by the contraction produces a radical change in the hydraulic radius. Water flowing in a river channel is governed by the same immutable laws as when flowing in pipes, but theses laws are so modified in the river by those governing the flow of sediment that effects are produced which are erroneously termed exceptions to general laws. For example if a given pipe is replaced by one of less diameter, the head (slope) must be increased to obtain the same discharge.

"This guidebook introduces the basic principles and technical procedures for the analysis of open channel flows in natural river systems. Pragmatic methods for the appropriate application and selection of numerical models for river engineering investigations are presented here with a minimal amount of theory. Chapters review multidimensional flow analysis, unsteady flow, steady flow-water surface profiles, and water surface profiles with movable boundaries. The progressive order of these technical chapters illustrates how each successive approach derives from the prior approach. Each chapter provides guidelines, data requirements, computational procedures, and examples. Past experiences and results of previous numerical model applications to river hydraulics and corresponding field observations reveal key information for detecting and avoiding problems in planning, performing, and reporting future studies."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

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.
