Book Description
Energy dissipators are an important element of hydraulic structures as transition between the highly explosive high velocity flow and the sensitive tailwater. This volume examines energy dissipators mainly in connection with dam structures and provides a review of design methods. It includes topics such as hydraulic jump, stilling basins, ski jumps and plunge pools. It also introduces a general account of various methods of dissipation, as well as the governing flow mechanisms.

Book Description
Stilling basins utili z ing a hydraulic jump for energy dissipation are w i d e l y used in hydraulic engineering . D a Vinci was the first to describe the hydraulic jump, and Bidone conducted classical experiments about 170 years ago . Stilling basins w e r e developed in the thirties with signif- cant design improvements being made during the last sixty years . Although w e l l - a c c e p t e d guidelines for a successful design are presently available, the information for the design of such dissipators is not yet compiled in book form . This book provides state-of-the-art information on hydraulic jumps and associat ed stilling basins . A large numbe r of papers on the to pics are reviewed. T h e present trends of the art of designing a stilli ng basin are discussed and ideas for future research are outlined. Design criteria and recommendat ions are frequently given . However, this should not be considered as a r eady-to -use guideline since the design of an effective stilling basin is much more comple x than following general design steps . The book is divided into two parts. Part 1 on hydraulic jumps is c- prised of chapters 2 to 5. Part 2 consisting of chapters 6 to 14 deals with various hydraulic structures used to dissipate energy. The lists of notation and references are provided in each part separately although the same notation is u sed throughout.

Book Description
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.

Book Description
Although hundreds of stilling basins and energy­dissipating devices have been designed in conjunction with spillways, outlet works, and canal structures, it is often necessary to make model studies of individual structures to be certain that these will operate as anticipated. The reason for these repetitive tests is that a factor of uncertainty exists regarding the overall performance characteristics of energy dissipators. The many laboratory studies made on individual structures over a period of years have been made by different personnel, for different groups of designers, each structure having different allowable design limitations. Since no two structures were exactly alike, attempts to generalize the assembled data resulted in sketchy and, at times, inconsistent results having only vague connecting links. Extensive library research into the works of others revealed the fact that the necessary correlation factors are nonexistent. To fill the need for up-to-date hydraulic design information on stilling basins and energy dissipators, a research program on this general subject was begun with a study of the hydraulic jump, observing all phases as it occurs in open channel flow. With a broader understanding of this phenomenon it was then possible to proceed to the more practical aspects of stilling basin design. This monograph generalizes the design of stilling basins, energy dissipators of several kinds and associated appurtenances. General design rules are presented so that the necessary dimensions for a particular structure may be easily and quickly determined, and the selected values checked by others without the need for exceptional judgment or extensive previous experience. Proper use of the material in this monograph will eliminate the need for hydraulic model tests on many individual structures, particularly the smaller ones. Designs of structures obtained by following the recommendations presented here will be conservative in that they will provide a desirable factor of safety. However, model studies will still prove beneficial to reduce structure sizes further, to account for nonsymmetrical conditions of approach or getaway, or to evaluate other unusual conditions not described herein.
