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 all of the main methods of analysis. With clear examples and relevant case studies, using both laboratory models and full- size bridges in the field, it is not only a thorough and accessible introduction to bridge hydraulics, but also a guide that will enable engineers to produce authoritative analyses and more effective designs. eBook available with sample pages: 0203028414
The book explores the theoretical background of one of the most
widespread activities in hydrocarbon wells, that of hydraulic
fracturing. A comprehensive treatment of the basic phenomena
includes: linear elasticity, stresses, fracture geometry and
rheology. The diverse concepts of mechanics are integrated into a
coherent description of hydraulic fracture propagation. The
chapters in the book are cross-referenced throughout and the
connections between the various phenomena are emphasized. The book
offers readers a unique approach to the subject with the use of
many numerical examples.
This unique single-source reference-the first book of its kind to
address systematically the problems involved in the field-offers
comprehensive coverage of hydraulic system troubleshooting and
encourages change in the trial-and-error methods common in
rectifying problems and restoring system downtime, furnishing a new
paradigm for troubleshooting methodology.

This is an examination of free water hydraulics. The topics covered
in this book range from hydrostatic force calculations to the
refraction, reflection and diffraction of oscillatory water waves.
The author draws a careful distinction between kinematic and
dynamic motions - the latter is treated in detail by the method of
characteristics, which is regarded as one of the most rigorous
approaches to unsteady flow. A special feature is the final chapter
in which the author turns to the disruption of free surfaces by air
and bubble motion, particularly in pipes.
This book focuses on hydraulic components and machines, and
illustrates how a machine's noise-radiating surfaces affect noise.
It reviews the basics and terminology of sound, vibration,
vibration isolation, fluid pulsations, Fourier analysis,
cavitation, hydraulic shock, and enclosure design.
This book discusses the pump's role in electrohydraulic systems and
its use as a power source to a control loop, and provides a good
understanding of the basics, complemented by working knowledge of
the "real world." It is intended for engineers and students who
have studied feedback control theory.
This is a practical handbook providing an introduction to the
equipment, maintenance and operation of solar pumping systems. It
identifies situations where solar pumps may be appropriate and it
reviews developments in solar pumping technology.
First published in 1991. The experiential base from which this book
is written the author's seminar for psychiatric residents which
emphasizes that self-disclosure with colleagues is an important
aspect of becoming a therapist. The ability to look at and listen
to one's own work along with one's peers is important in the
maturation process. In order to construct a context in which it is
possible to learn from each other, I share many of my own
psychotherapeutic experiences. More than this, however, Lewis
shares personal experiences when they seem appropriate to the
teaching-learning process.
Primarily written as course material on flood control and drainage
engineering for advanced students of civil engineering, this new
fourth edition is again thoroughly revised. It accommodates recent
developments in remote sensing, information technology and GIS
technology. New added material deals with flood management due to
Tsunami waves, flooding due to dam failure and breaking of
embankments, application of dredging technologies, problems of
flood forecasting, flood plain prioritization and flood hazard
zoning, and engineering measures for flood control. Drainage
improvement is tackled, with particular regard to salinity and
coastal aquifer management from the ingress of sea water. The book
includes design problem-solving and case studies, making it
practical and applications-oriented. The subject matter will be of
considerable interest to civil engineers, agricultural engineers,
architects and town planners, as well as other government and
non-government organizations.
Floods cause distress and damage wherever and whenever they
happen. Flooding from rivers, estuaries and the sea threatens many
millions of people worldwide and economic and insurance losses from
flooding have increased significantly since 1990. Across the
European Union, flood management policy is changing in response to
the EU Directive on the assessment and management of flood risks,
which requires a move from flood protection and defence to
comprehensive flood risk management.
Flood Risk Management: Research and Practice includes about 200
contributions from the international conference FLOODrisk 2008
(Oxford, UK, 30 September 2 October 2008). FLOODrisk 2008 was an
initiative of the FLOODsite research project on Integrated Flood
Risk Analysis and Management Methodologies. FLOODsite was a major
Integrated Project in the European Commission Sixth Framework
Programme; contract number GOCE-CT-2004-505420. The conference
provided a forum for leading researchers, flood risk managers,
policy makers and practitioners from government, commercial and
research organisations to gain an overview of advances in this
important subject. Flood risk management practice crosses several
professions and disciplines and these are represented in the
breadth of the scope of the conference and these proceedings. The
conference covered all aspects of flood risk: the causes of floods,
their impacts on people, property and the environment, and
portfolios of risk management measuresm, while the principal themes
included: climate change, estimation of extremes, flash floods,
flood forecasting and warning, inundation modelling, systems
analysis, uncertainty, international programmes, flood defence
infrastructure and assets, environmental impacts, human and social
impacts, vulnerability and resilience, risk sharing, equity and
social justice, and, civil contingency planning and emergency
management.
Flood Risk Management: Research and Practice will be of interest
to an international readership, ranging from authorities,
consultants and engineers involved in flood management;
researchers, post graduate lecturers and students, to policy
makers, particularly at national level.
"Showcases the beneftis and potential advantages of water
hydraulics over oil-based media. Interweaves examples and
excercises throughout the text to illustrate critical concepts,
with helpful appendices on abbreviations, symbols, conversion
factors, and water contaminants, and glossary sections."
The first of its kind, this modern, comprehensive text covers both analysis and design of piping systems. The authors begin with a review of basic hydraulic principles, with emphasis on their use in pumped pipelines, manifolds, and the analysis and design of large pipe networks. After the reader obtains an understanding of how these principles are implemented in computer solutions for steady state problems, the focus then turns to unsteady hydraulics. These are covered at three levels:
Reviewing basic fluid power principles, this updated Second Edition

and electrical systems and components. Examines the root causes of
failures in items such as hydraulic pumps and motors, air motors,
hydraulic and pneumatic valves, compressors, accumulators, filters,
seals, cylinders, tubing, fittings, and hoses Fully revised and
expanded throughout, Fluid Power Troubleshooting, Second Edition
stresses the latest developments in understanding the complex
interactions of components within a fluid power system cartridge
valve systems, proportional valve and servo-systems, and compressed
air drying and filtering noise reduction and other environmental
concerns the control of contaminants in hydraulic and pneumatic
systems the selection and care of hydraulic system fluid the
reduction of leaks in fluid power systems and much more
This book describes the fundamental phenomena of, and computational
methods for, hydraulic transients, such as the self-stabilization
effect, restriction of the Joukowsky equation, real relations
between the rigid and elastic water column theories, the role of
wave propagation speed, mechanism of the attenuation of pressure
fluctuations, etc. A new wave tracking method is described in great
detail and, supported by the established conservation and traveling
laws of shockwaves, offers a number of advantages. The book puts
forward a novel method that allows transient flows to be directly
computed at each time node during a transient process, and explains
the differences and relations between the rigid and elastic water
column theories. To facilitate their use in hydropower
applications, the characteristics of pumps and turbines are
provided in suitable forms and examples. The book offers a valuable
reference guide for engineers and scientists, helping them make
transient computations for their own programming, while also
contributing to the final standardization of methods for transient
computations.
