The design of bridges across rivers and streams is a major component of many civil engineering projects. The size of waterways must be kept reasonably small for reasons of economy and yet be large enough to allow floods to pass. Bridge Hydraulics is the first book to consider both arched and rectangular waterway openings in detail and to describe a

Open Channel Hydraulics, Second Edition provides extensive coverage of open channel design, with comprehensive discussions on fundamental equations and their application to open channel hydraulics. The book includes practical formulas to compute flow rates or discharge, depths and other relevant quantities in open channel hydraulics. In addition, it also explains how mutual interaction of interconnected channels can affect the channel design. With coverage of the theoretical background, practical guidance to the design of open channels and other hydraulic structures, advanced topics, the latest research in the field, and real-world applications, this new edition offers an unparalleled user-friendly study reference. - Introduces and explains all the main topics on open channel flows using numerous worked examples to illustrate key points - Features extensive coverage of bridge hydraulics and scour - important topics civil engineers need to know as aging bridges are a major concern - Includes Malcherek's momentum approach where applicable

Now in its fifth edition, Hydraulics in Civil and Environmental Engineering combines thorough coverage of the basic principles of civil engineering hydraulics with wide-ranging treatment of practical, real-world applications. This classic text is carefully structured into two parts to address principles before moving on to more advanced topics. The first part focuses on fundamentals, including hydrostatics, hydrodynamics, pipe and open channel flow, wave theory, physical modeling, hydrology, and sediment transport. The second part illustrates the engineering applications of these fundamental principles to pipeline system design; hydraulic structures; and river, canal, and coastal engineering—including up-to-date environmental implications. A chapter on computational hydraulics demonstrates the application of computational simulation techniques to modern design in a variety of contexts. What’s New in This Edition Substantive revisions of the chapters on hydraulic machines, flood hydrology, and computational modeling New material added to the chapters on hydrostatics, principles of fluid flow, behavior of real fluids, open channel flow, pressure surge in pipelines, wave theory, sediment transport, river engineering, and coastal engineering The latest recommendations on climate change predictions, impacts, and adaptation measures Updated references Hydraulics in Civil and Environmental Engineering, Fifth Edition is an essential resource for students and practitioners of civil, environmental, and public health engineering and associated disciplines. It is comprehensive, fully illustrated, and contains many worked examples. Spreadsheets and useful links to other web pages are available on an accompanying website, and a solutions manual is available to lecturers.

Most analyses of bridge hydraulics for flood flows are performed using the Army Corps of Engineers HEC-RAS (Hydrologic Engineering Centers River Analysis System) computer program. This study was carried out to compare results of HEC-RAS bridge modeling with experiments performed in a laboratory flume. The study was intended to add some insight into the effect of bridge hydraulic features such as ineffective flow regions, weir overflow and flow through skewed bridges. This insight should be useful for bridge engineers in HEC-RAS bridge modeling endeavors. A laboratory flume was constructed specifically for this project. The flume cross section has a main channel region and relatively wide left and right overbank regions. Different bridge scenarios were modeled. Froude number similarity was used to "scale up" model parameters and create prototype HEC-RAS hydraulic models simulating laboratory model conditions. Water surface profiles were compared for corresponding HEC-RAS and laboratory results.

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.

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).
