Practical 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. With 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. Special 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. Topics 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.

Open Channel Flow, 2nd edition is written for senior-level undergraduate and graduate courses on steady and unsteady open-channel flow. The book is comprised of two parts: Part I covers steady flow and Part II describes unsteady flow. The second edition features considerable emphasis on the presentation of modern methods for computer analyses; full coverage of unsteady flow; inclusion of typical computer programs; new problem sets and a complete solution manual for instructors.
The Second Edition of the Practical Hydraulics Handbook is a must for all those who work with water utility systems. Presented in workbook format and emphasizing practical applications, this Handbook is perfect for hydraulic engineers, technicians, operating personnel, supervisors, managers, consultants, and students. The exceptionally well-organized chapters include information on pressurized systems and open channel flow, principles of energy and force, flow calculations and measurement, pumps, and pumping applications. This latest edition of the Practical Hydraulics Handbook includes new exercises at the end of each chapter and detailed solutions to selected exercises. The well-chosen exercises allow readers to practice applications of the theory and to test their knowledge of the material. The solutions provide guidance and problem-solving techniques that can be used both in the field and in the lab. Reference tables are also provided for calculations of friction loss, velocity, pipe fullness, well drawdown, English/metric conversions, power, and metered flow. These tables make calculations easier and minimize the chance for error. In this new edition of Practical Hydraulics Handbook, all of the major principles and calculations dealing with the hydraulics of water systems are covered, and new and expanded material has been added.

The second, enlarged edition of this established reference integrates many new insights into wastewater hydraulics. This work serves as a reference for researchers but also is a basis for practicing engineers. It can be used as a text book for graduate students, although it has the characteristics of a reference book. It addresses mainly the sewer hydraulician but also general hydraulic engineers who have to tackle many a problem in daily life, and who will not always find an appropriate solution. Each chapter is introduced with a summary to outline the contents. To illustrate application of the theory, examples are presented to explain the computational procedures. Further, to relate present knowledge to the history of hydraulics, some key dates on noteworthy hydraulicians are quoted. A historical note on the development of wastewater hydraulics is also added. References are given at the end of each chapter, and they are often helpful starting points for further reading. Each notation is defined when introduced, and listed alphabetically at the end of each chapter. This new edition includes in particular sideweirs with throttling pipes, drop shafts with an account on the two-phase flow features, as well as conduit choking due to direct or undular hydraulic jumps.

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: hydraulic roughness water levels (and corresponding channel and structure conveyance) flow (given slope); section-average and spatial velocities backwater profiles upstream of a known flow-head control e.g. weir (steady) afflux upstream of bridges and culverts uncertainty in water level The CES-AES software and tutorial are openly available at www.river-conveyance.net (see also Downloads & Updates tab).
