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.

Fluvial Hydraulics provides a sound qualitative and quantitative understanding of water and sediment flows in natural rivers. This understanding is essential for modeling and predicting hydrologic and geomorphologic processes, erosion, sediment transport, water supply and quality, habitat management, and flood hazards. This book's coverage bridges the gap between the highly quantitative mechanics-based civil-engineering approach to stream hydraulics and the more qualitative treatments of fluvial geomorphology typical of earth-sciences and natural-resources curricula. Measurements of natural river flows illustrate many central concepts.
The book is specifically designed for upper-level students and practitioners who are interested in a fundamental understanding of river behavior. An introduction to the history of fluvial hydraulics and an overview of the morphology and hydrology of rivers provides the context for the rest of the text. A thorough understanding of water properties, including turbulence, is developed via a series of simple thought experiments. The bases of the equations that are used to describe and predict river flows are systematically presented, including dimensional analysis. Subsequent chapters build logically on these foundations, covering velocity distributions, new insights to the central topic of flow resistance, the magnitudes of forces in natural river flows, the principles of conservation of energy and momentum, the prediction of water-surface profiles, the principles of flow measurement, mechanics, and geomorphic aspects of sediment transport. The book will be especially valuable in providing a scientific basis for the growing field of river restoration.
An appendix reviews dimenstions, units, and numerical precision. Over 250 references are cited, providing an entree to the extensive multi-disciplinary literature on rivers. The book's website provides suggestions for student exercises and makes available extensive data bases of measured streamflows for student exploration.

In recent years there has been a revival of interest in the hydraulic ram pump, a renewable energy water-lifting device. "Hydraulic Ram Pumps" aims to introduce the reader to all aspects of ram pumps. It should be useful to technicians and engineers involved in rural water supply, whether they are assessing the suitability of ram pumps, installing a system or contemplating local manufacture. It gives practical guidelines for the installation and operation of water supply systems based on such pumps, as well as describing the operation of the pump and the factors affecting its performance.;The reader is taken through the steps involved in designing and installing a complete system, steps that should be applicable to any model of ram pump available. Details of one pump, designed for local manufacture in developing countries, are given along with some notes on ram pump design for those wishing to develop their own models.;A number of illustrations are used alongside text in order to make the information useful to a wide range of non-specialist readers. Readers are welcome to photocopy the diagrams and add labels in other languages in order for training purposes.

The state-of-the-art in fluvial hydrodynamics can be examined only through a careful exploration of the theoretical development and applied engineering technology. The book is primarily focused, since most up-to-date research findings in the field are presented, on the research aspects that involve a comprehensive knowledge of sediment dynamics in turbulent flows. It begins with the fundamentals of hydrodynamics and particle motion followed by turbulence characteristics related to sediment motion. Then, the sediment dynamics is analysed from a classical perspective by applying the mean bed shear approach and additionally incorporating a statistical description for the role of turbulence. The work finally examines the local scour problems at hydraulic structures and scale models. It is intended to design as a course textbook in graduate / research level and a guide for the field engineers as well, keeping up with modern technological developments. Therefore, as a simple prerequisite, the background of the readers should have a basic knowledge in hydraulics in undergraduate level and an understanding of fundamentals of calculus.

Mathematical modeling and numerical simulation in fluid mechanics are topics of great importance both in theory and technical applications. The present book attempts to describe the current status in various areas of research. The 10 chapters, mostly survey articles, are written by internationally renowned specialists and offer a range of approaches to and views of the essential questions and problems. In particular, the theories of incompressible and compressible Navier-Stokes equations are considered, as well as stability theory and numerical methods in fluid mechanics. Although the book is primarily written for researchers in the field, it will also serve as a valuable source of information to graduate students.

This title includes a number of Open Access chapters. Hydraulic fracturing, or "fracking" as it is commonly known, refers to the practice of using liquids at very high pressures to fragment rock, thereby allowing natural gas to be harvested. This process increases energy resources but also has some negative environmental impacts as well. This book looks at the environmental impact. The first section looks at fracturing and the water supply, the second section looks at ecosystems and wildlife, while the final section examines the possible effects on human ecosystems and human health.

Large-Eddy Simulation (LES), which is an advanced eddy-resolving method for calculating turbulent flows, is used increasingly in Computational Fluid Dynamics, also for solving hydraulics and environmental flow problems. The method has generally great potential and is particularly suited for problems dominated by large-scale turbulent structures. This book gives an introduction to the LES method specially geared for hydraulic and environmental engineers. Compared with existing books on LES it is less theoretically and mathematically demanding and hence easier to follow, and it covers special features of flows in water bodies and summarizes the experience gained with LES for calculating such flows. The book was written primarily as an introduction to LES for hydraulic and environmental engineers, but it will also be very useful as an entry to the subject of LES for researchers and students in all fi elds of fl uids engineering. The applications part will further be useful to researchers interested in the physics of fl ows governed by the dynamics of coherent structures.

A Users Guide to Hydraulic Modelling and Experimentation provides a systematic, comprehensive summary of the progress made through HYDRALAB III . The book combines the expertise of many of the leading hydraulic experimentalists in Europe and identifies current best practice for carrying out state-of-the-art, modern laboratory investigations. In addition it gives an inventory and reviews recent advances in instrumentation and equipment that drive present and new developments in the subject. The Guide concentrates on four core areas ? waves, breakwaters, sediments and the relatively-new (but rapidly-developing) cross-disciplinary area of hydrodynamics/ecology. Progress made through the ?CoMIBBS? component of HYDRALAB III provides the material for a chapter focussed on guidance, principles and practice for composite modelling. There is detailed consideration of scaling and the degree of relevance of laboratory/physical modelling approaches for specific contexts included in each of the individual chapters. The Guide includes outputs from the workshops and several of the innovative transnational access projects that have been supported within HYDRALAB III, as well as the focussed joint research activities SANDS and CoMIBBS. Its primary purpose is to serve as a shared resource to disseminate the outstanding advances achieved within HYDRALAB III but, even more than this, it is a tribute to the human and institutional collaborations that led to and sustained the research advances, the human relationships that were strengthened and initiated through joint participation in the Programme, and the training opportunities that participation provided to the many young researchers engaged in the projects.

Throughout the world, boreholes and tubewells operate inefficiently or have been abandoned. Diagnosis of the problems requires hydrogeological and operational information, which is often not available because appropriate monitoring has not taken place. Guidelines on cost effective monitoring and maintenance need to be established; information on successful rehabilitation techniques is needed. This book forms the proceedings of a conference organised to exchange practical experience and scientific knowledge on these aspects of water wells.

This book provides comprehensive guidance on maintaining old waterfront structures, particularly gravity walls constructed with stone masonry, brick, blocks or mass concrete. It will be valuable for all engineers responsible for such structures.
