It is hoped that this work will serve as a study of energy-dissipation devices, of which our knowledge is still somewhat fragmentary. Experimental as well as design data are included to serve both research and design engineers. The reader will also find a considerable amount of material that either is new or has not been presented before.
A knowledge of the fundamental principles of fluid mechanics is presupposed, and derivations have been omitted except where they have appeared necessary in explaining new methods. However, a brief chapter is included to present the fundamentals of open-channel flow and to serve as a review of the subject.
Many types of energy dissipators have been used throughout the world, and usually the design of each has varied quite radically to meet the problem at hand. The best type suited for protection against scour at a particular location depends largely upon the relationship between the existing tailwater depth and the depth required to form a hydraulic jump. Analyses are made of the formation of the hydraulic jump in various-shaped channels. As part of the analyses, a large number of empirical formulas have been developed, which can be used directly to solve most practical problems. Criteria for the design of stilling basins and bucket-type dissipators are presented to serve as a guide in designing such structures. A chapter is included on the subject of erosion and channel retrogression below dams.
