Energy Dissipators and Hydraulic Jump

Willi H. Hager

The book gives an up-to-date review of the flow features in a hydraulic jump, and its technical applications as an energy dissipator. Based on a vast technical literature, the present ideas are summarised, compared with each other and generalised whenever possible. Particular stress is laid on explaining the basic terms, describing effects of energy dissipation on various neighboring fields and presenting prototype experiences with hydraulic jump dissipators. These structures are also compared with other means of energy dissipation found in dam engineering. As a result civil engineers working both in practice and in research may gain an impression of what is actually being done in a rapidly expanding field of applied hydraulics, and obtain additional information on a subject in which reference books are rare.
