Hydraulics has a reputation for being a complex, even intimidating, discipline. Put simply, hydraulics is the study of how water and similar fluids behave and can be harnessed for practical use. It is one of the fundamental scientific and engineering subjects and many professions demand a working knowledge of its basic concepts, yet most hydraulics textbooks are aimed at readers with a strong engineering or mathematical background.

Practical Hydraulics approaches the subject from basic principles and demonstrates how these are applied in practice. It is clearly written and includes many illustrations and examples. It will appeal to a wide range of professionals and students needing an introduction to the subject, from farmers irrigating crops to fire crews putting out fires with high-pressure water hoses. However hydraulics is not just about water. Many other fluids behave in the same way and so affect a wide range of people from doctors, needing to know how blood flows in veins, to car designers, wanting to save fuel by reducing drag.

Mechanistic models are often employed to simulate processes in coastal environments. However, these predictive tools are highly specialized, involve certain assumptions and limitations, and can be manipulated only by experienced engineers who have a thorough understanding of the underlying principles. This results in significant constraints on their manipulation as well as large gaps in understanding and expectations between the developers and users of a model.

Recent advancements in soft computing technologies make it possible to integrate machine learning capabilities into numerical modelling systems in order to bridge the gaps and lessen the demands on human experts. This book reviews the state-of-the-art in conventional coastal modelling as well as in the increasingly popular integration of various artificial intelligence technologies into coastal modelling. Conventional hydrodynamic and water quality modelling techniques comprise finite difference and finite element methods. The novel algorithms and methods include knowledge-based systems, genetic algorithms, artificial neural networks, and fuzzy inference systems.

Different soft computing methods contribute towards accurate and reliable prediction of coastal processes. Combining these techniques and harnessing their benefits has the potential to make extremely powerful modelling tools.

Historically, much harm has been done by well-meaning coastal engineering attempts, which seemed like good ideas on paper but which failed to allow for practical issues. For this reason, it is vital that theories and models are well grounded in practice. This second edition brings the models and examples of practice up to date. It has expanded coverage of tsunamis and generating energy from waves to focus both on the great dangers and the great opportunities that the ocean presents to the coastal zone. With an emphasis on practice and detailed modelling, this is a thorough introduction to all aspects of coastal processes, morphology, and design of coastal defences. It describes numerous case studies to illustrate the successful application of mathematical modelling to real-world practice. A must-have book for engineering students looking to specialize in coastal engineering and management.

Recent advances in technology have permitted the construction of large dams, reservoirs and channels. This progress has necessitated the development of new design and construction techniques, particularly with the provision of adequate flood release facilities. Chutes and spillways are designed to spill large water discharges over a hydraulic structure (e.g. dam, weir) without major damage to the structure itself and to its environment. At the hydraulic structure, the fl ood waters rush as an open channel flow or free-falling jet, and it is essential to dissipate a very signifi cant part of the fl ow kinetic energy to avoid damage to the hydraulic structure and its surroundings. Energy dissipation may be realised by a wide range of design techniques. A number of modern developments have demonstrated that such energy dissipation may be achieved (a) along the chute, (b) in a downstream energy dissipator, or (c) a combination of both.

The magnitude of turbulent energy that must be dissipated in hydraulic structures is enormous even in small rural and urban structures. For a small storm waterway discharging 4 m3/s at a 3 m high drop, the turbulent kinetic energy flux per unit time is 120 kW! At a large dam, the rate of energy dissipation can exceed tens to hundreds of gigawatts; that is, many times the energy production rate of nuclear power plants. Many engineers have never been exposed to the complexity of energy dissipator designs, to the physical processes taking place and to the structural challenges. Several energy dissipators, spillways and storm waterways failed because of poor engineering design. It is believed that a major issue affecting these failures was the lack of understanding of the basic turbulent dissipation processes and of the interactions between free-surface aeration and flow turbulence.

In that context, an authoritative reference book on energy dissipation in hydraulic structures is proposed here. The book contents encompass a range of design techniques including block ramps, stepped spillways, hydraulic jump stilling basins, ski jumps and impact dissipators.

Small Dams: Planning, Construction and Maintenance has been written to provide a practical approach and guide to determining catchment yield and the amount of water required in a dam, advising on selecting and working with engineers and contractors, as well as outlining the cause of dam failures and how to remedy problems quickly. It also covers relevant legislation, environmental and ecological issues.

Employing the principles in this book, in conjunction with heeding the advice of suitably experienced and qualifi ed engineers and contractors, will reduce the risk of failure and help to ensure the long term success of any small dam in question. Small Dams will be an invaluable resource for anyone who owns a dam, and a useful reference for agencies, contractors and engineers.

The author, Barry Lewis, has over forty years of experience as an engineer and has written extensively on farm dams, soil conservation, catchment management and the environmental impact of dams both on and off streams. He was also directly involved in the licensing and regulating of small dams in Australia.
