Fluvial Hydraulics


Book Description

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.




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 Flow 2020


Book Description

Rivers form one of the lifelines in our society by providing essential services such as availability of fresh water, navigation, energy, ecosystem services, and flood conveyance. Because of this essential role, mankind has interfered continuously in order to benefit most and at the same time avoid adverse consequences such as flood risk and droughts. This has resulted in often highly engineered rivers with a narrow set of functions. In the last decades rivers are increasingly considered in a more holistic manner as a system with a multitude of interdependent processes. River research and engineering has therefore added to the river fundamentals also themes like ecohydraulics, consequences of climate change, and urbanisation. River Flow 2020 contains the contributions presented at the 10th conference on Fluvial Hydraulics, River Flow 2020, organised under the auspices of the Committee on Fluvial Hydraulics of the International Association for Hydro-Environment Engineering and Research (IAHR). What should have been a lively physical gathering of researchers, students and practitioners, was converted into an online event as the COVID-19 pandemic hindered international travelling and large gatherings of people. Nevertheless, the fluvial hydraulics community showed their interest and to be very much alive with a high number of participations for such event. Since its first edition in 2002, in Louvain-la-Neuve, this series of conferences has found a large and loyal audience in the river research and engineering community while being also attractive to the new researchers and young professionals. This is highlighted by the large number of contributions applying for the Coleman award for young researchers, and also by the number of applications and attendants to the Master Classes which are aimed at young researchers and students. River Flow 2020 aims to provide an updated overview of the ongoing research in this wide range of topics, and contains five major themes which are focus of research in the fluvial environment: river fundamentals, the digital river, the healthy river, extreme events and rivers under pressure. Other highlights of River Flow 2020 include the substantial number of interdisciplinary subthemes and sessions of special interest. The contributions will therefore be of interest to academics in hydraulics, hydrology and environmental engineering as well as practitioners that would like to be updated about the newest findings and hot themes in river research and engineering.

River management and restoration are also considered in detail, making this volume of direct relevance to those concerned with cutting edge research and its application for water resource management. Aimed at academics and postgraduate researchers in departments of physical geography, earth sciences, environmental science, environmental management, civil engineering, biology, zoology, botany and ecology; Ecohydraulics: An Integrated Approach will be of direct relevance to academics, researchers and professionals working in environmental research organisations, national agencies and consultancies.




River Flow 2002


Book Description

Rivers provide many contributions to human well-being: water supply for domestic use, irrigation and industry, sustainable energy, convenient transport links and valuable wildlife habitats. Rivers also creat hazards in the form of flooding and geomorphic events. The need for observation, analysis and control of fluvial processes has increased in line with the degree of conflicting pressures on rivers during the last decades. The discipline of River Hydraulics is solicited to guide engineering works, evaluate environmental impacts and mitigate hazards. Simultaneously, new modelling tools have emerged from advances in physical understanding, computational methods and measurement techniques. Organised under the auspices of the International Association of Hydraulic Engineering and Research (IAHR), the International Conference River Flow 2002 sought to provide a forum for researchers involved in such developments. The three major topic of this proceedings are: hydrodynamics of river flow; sediment transport in rivers; and tools for flow modelling.
