Hydraulics of Spillways and Energy Dissipators

Hydraulics of Spillways and Energy Dissipators The need for a comprehensive book on the hydraulics of spillways and energy dissipators. has long been recognized. Various topics related to spillways and energy dissipators are available in sources mainly devoted to the design. of dams, textbooks on hydraulics and open channel flow, and hydraulics handbooks. . As a result, the gap between advances in knowledge and its formal documentation in books and treatises widens. Among the many examples that demonstrate this lag, a typical one is the air vent on spillways to reduce cavitation damage. Although the beneficial effects of aeration were in the early fifties. but considerable research to understand the hydraulics of this phenomenon. had been carried out, from the sixties and in the late seventies aerators were installed on existing structures, but it was not until the eighties that aerators became an integral component. Spillway Design It is noteworthy that until the late eighties no book on spillways included the subject of aeration. This pattern of lag continues, as several topics of vital importance are not comprehensively and coherently included in any of the book literature. A few notable ones are: construction stages of spillways, dual-purpose spillways for flood as well as sediment disposal, protection of the spillway of earth dams used as spillways. Obviously, such a book would be the easiest way for the reader to access information on the latest developments in this field. The present book is the result of such an effort.
