Practical Channel Hydraulics, 2nd edition: Roughness, Conveyance and Afflux

Product Description \nPractical Channel Hydraulics is a technical guide for estimating flood water levels in rivers using the innovative software known as the Conveyance and Afflux Estimation System (CES-AES). The stand alone software is freely available at HR Wallingford’s website www.river-conveyance.net. The conveyance engine has also been embedded within industry standard river modelling software such as InfoWorks RS and Flood Modeller Pro. This 2nd Edition has been greatly expanded through the addition of Chapters 6-8, which now supply the background to the Shiono and Knight Method (SKM), upon which the CES-AES is largely based.\nWith the need to estimate river levels more accurately, computational methods are now frequently embedded in flood risk management procedures, as for example in ISO 18320 (‘Determination of the stage-discharge relationship’), in which both the SKM and CES feature. The CES-AES incorporates five main components: A Roughness Adviser, A Conveyance Generator, an Uncertainty Estimator, a Backwater Module and an Afflux Estimator. The SKM provides an alternative approach, solving the governing equation analytically or numerically using Excel, or with the short FORTRAN program provided.\nSpecial attention is paid to calculating the distributions of boundary shear stress distributions in channels of different shape, and to appropriate formulations for resistance and drag forces, including those on trees in floodplains. Worked examples are given for flows in a wide range of channel types (size, shape, cover, sinuosity), ranging from small scale laboratory flumes (Q = 2.0 1s-1) to European rivers (~2,000 m3s-1), and large-scale world rivers (> 23,000 m3s-1), a ~ 107 range in discharge. Sites from rivers in the UK, France, China, New Zealand and Ecuador are considered. \nTopics are introduced initially at a simplified level, and get progressively more complex in later chapters. This book is intended for post graduate level students and practising engineers or hydrologists engaged in flood risk management, as well as those who may simply just wish to learn more about modelling flows in rivers. 
 About the Author 
Professor Donald Knight retired from the University of Birmingham in December 2007, after teaching and undertaking research in the Department of Civil Engineering for just over 39 years. He continues research as an Emeritus Professor at Birmingham. He has co-authored several books and published over 160 refereed journal and conference papers on open channel flow, modelling, boundary shear stress, sediment mechanics and flooding, including several review articles. Donald is assistant Editor of the Journal of Disaster Research (Tokyo University) and of Water and Sediment Erosion Research (Beijing & Tsinghua Universities).\nCaroline Hazlewood is Group Manager at HR Wallingford. She has a PhD and MSc in Hydraulic Engineering and a BSc in Civil Engineering. She is a member of International Association for Hydro-Environment Engineering and Research (IAHR) and member of the Journal of Flood Risk Management (JFRM) Editorial Board.\nRob Lamb is Managing Director of the JBA Trust, a research and educational charity funded by the JBA Group. His background is in hydrology and numerical modelling, with research interests in flooding and risk analysis in environmental and engineered systems. He has worked at the Centre for Ecology and Hydrology in Wallingford, and, from 2002, at JBA Consulting. Since 2013, he has been an Honorary Professor at Lancaster University’s Environment Centre. In 2016 he was part of the British government’s scientific advisory group on flooding.\nProfessor Paul Samuels is a Technical Director at HR Wallingford and a Visiting Industrial Professor at the University of Bristol, UK.\nShiono Koji is Emeritus Professor at Loughborough University since 2017. He studied his PhD on vertical turbulent exchange in stratified flow at the Department of Civil Engineering, Birmingham

Hydrology in Practice, Fourth Edition

Hydrology in Practice is an excellent and very successful introductory text for engineering hydrology students who go on to be practitioners in consultancies, the Environment Agency, and elsewhere. This fourth edition of Hydrology in Practice, while retaining all that is excellent about its predecessor, by Elizabeth M. Shaw, replaces the material on the Flood Studies Report with an equivalent section on the methods of the Flood Estimation Handbook and its revisions. Other completely revised sections on instrumentation and modelling reflect the many changes that have occurred over recent years. The updated text has taken advantage of the extensive practical experience of the staff of JBA Consulting who use the methods described on a day-to-day basis. Topical case studies further enhance the text and the way in which students at undergraduate and MSc level can relate to it. The fourth edition will also have a wider appeal outside the UK by including new material on hydrological processes, which also relate to courses in geography and environmental science departments. In this respect the book draws on the expertise of Keith J. Beven and Nick A. Chappell, who have extensive experience of field hydrological studies in a variety of different environments, and have taught undergraduate hydrology courses for many years. Second- and final-year undergraduate (and MSc) students of hydrology in engineering, environmental science, and geography departments across the globe, as well as professionals in environmental protection agencies and consultancies, will find this book invaluable. It is likely to be the course text for every undergraduate/MSc hydrology course in the UK and in many cases overseas too.

A technical reference guide and instruction text for the estimation of flood and drainage water levels in rivers, waterways and drainage channels. It is written as a user’s manual for the openly available innovative Conveyance and Afflux Estimation System (CES-AES) software, with which water levels, flows and velocities in channels can be calculated. The impact of factors influencing these levels and the sensitivity of channels to extreme levels can also be assessed. Approaches and solutions are focused on addressing environmental, flood risk and land drainage objectives. Practical Channel Hydraulics is the first reference guide that focuses in detail on estimating roughness, conveyance and afflux in fluvial hydraulics. With its universal approach and the application of metric units, both book and software serve an international audience of consultants and engineers dealing with river modelling, flood risk assessment, maintenance of watercourses and the design of drainage systems. Suited as course material for training graduate Master’s students in civil and environmental engineering or geomorphology who focus on river and flood engineering, as well as for professional training in flood risk management issues, open channel flow hydraulics and modelling. The CES-AES software development followed recommendations by practitioners and academics in the UK Network on Conveyance in River Flood Plain Systems, following the Autumn 2000 floods, that operating authorities should make better use of recent improved knowledge on conveyance and related flood (or drainage) level estimation. This led to a Targeted Programme of Research aimed at improving conveyance estimation and subsequent integration with other research on afflux at bridges and culverts at high flows. The CES-AES software tool aims to improve and assist with the estimation of: <ul>
<li>hydraulic roughness</li> <li>water levels (and corresponding channel and structure conveyance)</li> <li>flow (given slope); section-average and spatial velocities</li> <li>backwater profiles upstream of a known flow-head control e.g. weir (steady)</li> <li>afflux upstream of bridges and culverts</li> <li>uncertainty in water level</li> </ul> The CES-AES software and tutorial are openly available at www.river-conveyance.net (see also Downloads &amp; Updates tab).
