Practical Channel Hydraulics, 2nd edition

Roughness, Conveyance and Afflux

By: Donald W. Knight,Caroline Hazlewood,Rob Lamb,Paul G. Samuels,Koji Shiono

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.

Cognitive Behaviour Therapy for Obsessive-compulsive Disorder

By: Victoria Bream,Fiona Challacombe,Asmita Palmer,Paul Salkovskis

Obsessive-compulsive disorder can be a very disabling and distressing problem. Cognitive behavioural therapy (CBT) has been shown to be very effective in helping people to overcome OCD. However, OCD is a highly heterogeneous disorder, often complicated by contextual factors, and therapists are often left wondering how to apply their knowledge of treatment to the particular problems as they face them in clinical practice. This book provides the reader with an understanding of the background to and principles of using CBT for OCD in a clear practical 'how to' style. It also elucidates the particular challenges and solutions in applying CBT for OCD using illustrative case material and guidance on formulation-driven intervention. The book also addresses commonly occurring complexities in the treatment of OCD, for example working with comorbidity, perfectionism, shame and family involvement in symptoms. Throughout the book, the authors provide tips on receiving and giving supervision to trouble-shoot commonly encountered problems, resulting in a guide that can help clinicians at all levels of experience.

Aquatic Photosynthesis

Second Edition

By: Paul G. Falkowski,John A. Raven

Aquatic Photosynthesis is a comprehensive guide to understanding the evolution and ecology of photosynthesis in aquatic environments. This second edition, thoroughly revised to bring it up to date, describes how one of the most fundamental metabolic processes evolved and transformed the surface chemistry of the Earth. The book focuses on recent biochemical and biophysical advances and the molecular biological techniques that have made them possible. In ten chapters that are self-contained but that build upon information presented earlier, the book starts with a reductionist, biophysical description of the photosynthetic reactions. It then moves through biochemical and molecular biological patterns in aquatic photoautotrophs, physiological and ecological principles, and global biogeochemical cycles. The book considers applications to ecology, and refers to historical developments. It can be used as a primary text in a lecture course, or as a supplemental text in a survey course such as biological oceanography, limnology, or biogeochemistry.

Practical Channel Hydraulics

Roughness, Conveyance and Afflux

By: Donald W. Knight,Caroline McGahey,Rob Lamb,Paul Samuels

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).
