This two-volume book is a comprehensive guide to designing, conducting and interpreting experiments in a broad range of topics associated with hydraulic engineering. It is the first substantial effort in hydraulic engineering to assemble in one place descriptions of all the components of experimentation along with a concise outline of essential theory to highlight the intrinsic connection between analytical and experimental research and illustrate the need for their complementary use. Providing end-to-end guidance to support experimentalists is long overdue, as most of the information can only be found in scientific papers or specialized monographs on laboratory and fieldwork practice. The book was prepared for college faculty, researchers, practitioners, and students involved in hydraulics experiments. Written by a team of more than 45 authors well-experienced in hydraulics experimentation, the book takes into account experiments performed under a range of conditions, including well-equipped and -staffed laboratories, and laboratories lacking aspects of advanced instrumentation and expertise. The book could serve as a textbook on hydraulics experiments. Its style is intentionally concise and makes frequent use of convenient summaries, tables and figures to present information. The writers provide specific guidance on methods and instruments currently used in hydraulics experiments, and emphasizes new and emerging measurement technologies and analysis methods. Extensive references enable interested readers to further explore details on each topic. Although the book focuses primarily on laboratory experiments, including hydraulic modelling, it also applies to fieldwork of varying complexity and accessibility.

One of the effects of global climate change is the increasing variability of extreme flood events and cyclones. Current measures to mitigate flood impacts, particularly in the urban environment, are based on previously-planned flood risk intervals and no longer provide sufficient protection. Being prepared for unexpected changes and extreme flood events asks for a paradigm shift in current strategies to avoid and manage flood disasters. In order to stem the increasing impact of urban floods, a major rethink of current planning and flood management policies and practice is required, taking into account different spatial and temporal scales. This book addresses a broad spectrum of relevant issues in the emerging field of urban flood management. It may act as a stimulus for further research and development in urban flood management while informing and engaging stakeholders in the promotion of integrated and cooperative approaches in water management. An interdisciplinary approach which will be of interest to all those who are active in water, risk and urban management.

Siltation in reservoirs has become an important problem when dams are getting older and stop functioning when the sediment has accumulated to a certain extent. With proper sediment management techniques, negative effects of sediment can be avoided and reservoir life and performance can be improved. This volume deals with reservoir sedimentation, deposition and removal. It provides the principles of sediment transport and gives guidelines to predict reservoir life. It presents several removal techniques, accompanied with detailed operation descriptions. With the help of the RESCON open source software, cost analysis tools to determine the optimum method for maintenance and operation of a reservoir can be applied. To illustrate practice and to assist the reader in setting up a sediment management operation, a number of case studies of existing large dams are included. Written by two experts on reservoir operation, this volume is intended for professionals and advanced students working on dam and reservoir design, construction, operation, maintenance and rehabilitation.

Modeling hydrologic changes and predicting their impact on watersheds is a dominant concern for hydrologists and other water resource professionals, civil and environmental engineers, and urban and regional planners. As such changes continue, it becomes more essential to have the most up-to-date tools with which to perform the proper analyses and modeling of the complex ecology, morphology, and physical processes that occur within watersheds. An application-oriented text, Modeling Hydrologic Change: Statistical Methods provides a step-by-step presentation of modeling procedures to help you properly analyze and model real-world data.

The text addresses modeling systems where change has affected data that will be used to calibrate and test models of the system. The use of actual hydrologic data will help you learn how to handle the vagaries of real-world hydrologic-change data. All four elements of the modeling process are discussed: conceptualization, formulation, calibration, and verification. Although the book is oriented towards the statistical aspects of modeling, a strong background in statistics is not required. The statistical and modeling methods discussed here will be of value to all disciplines involved in modeling change. With approximately 100 illustrations, Modeling Hydrologic Change will equip you with an understanding with which to perform the proper analyses and modeling of the complex processes that occur across various disciplines.

Some interesting case studies from around the world are also presented. This book is the first to bring together practical experience and theoretical understanding related to the latest scour evacuation methods. It will enhance future research and design activities as well as helping to improve safety of hydraulic structures and dams.

Stepped channel designs have been used for more than 3,500 years. A significant number of dams were built with overflow stepped spillways during the nineteenth and early twentieth centuries, before the design technique became outdated with the progresses in hydraulic jump stilling basin design. Recent advances in technology (e.g. RCC, polymer-coated gabion wire) have triggered a regain in interest for the stepped design, although much expertise had been lost in the last eighty years. The steps increase significantly the rate of energy dissipation taking place along the chute and reduce the size of the required downstream energy dissipation basin. Stepped cascades are used also in water treatment plants to enhance the air-water transfer of atmospheric gases (e.g. oxygen, nitrogen) and of volatile organic components (VOC). This book presents the state-of-the-art in stepped channel hydraulics. It is based upon the research expertise of the writer, his professional experience as an expert-consultant, and his experience in teaching stepped spillway hydraulics to undergraduate students, postgraduate research students and professionals since 1982. Results from more than forty-five laboratory studies and four prototype investigations were reanalyzed and compared, enabling the book to provide a new understanding of stepped channel hydraulics, aimed at both the research and professional communities.

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.

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.

Intermediate foundations are used as anchors for floating platforms and ancillary structures, foundations for steel jackets, and to support seafloor equipment and offshore wind turbines. When installed by suction, they are an economical alternative to piling, and also may be completely removed. They are usually circular in plan and are essentially rigid when laterally loaded. Length to diameter embedment ratios, L/D, generally vary between 0.5 and 10, spanning the gap between shallow and deep foundations, although these are indicative boundaries and the response, rather than the embedment ratio, defines an intermediate foundation. The first chapters introduce foundation types; compare shallow, intermediate and deep foundation models and design; define unique design issues that make intermediate foundations distinct from shallow and deep foundations, as well as list their hazards that mainly occur during installation. Later chapters cover installation, in-place resistance and in-place response, and miscellaneous design considerations. There is no general agreement as to which design methods/models are appropriate, so models should only be as accurate as the data. Therefore, several reasonably accurate models are provided together with comprehensive discussion and advice. Example calculations and over 200 references are also included. This is the first book dedicated to the geotechnical design of intermediate foundations, and it will appeal to professional engineers specialising in the offshore industry.

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.
