Energy Dissipators and Hydraulic Jump (Water Science and Technology Library)
(Stilling basins utili z ing a hydraulic jump for energy d...)
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.

Wastewater Hydraulics: Theory and Practice
( The second, enlarged edition of this established refere...)
The second, enlarged edition of this established reference integrates many new insights into wastewater hydraulics. This work serves as a reference for researchers but also is a basis for practicing engineers. It can be used as a text book for graduate students, although it has the characteristics of a reference book. It addresses mainly the sewer hydraulician but also general hydraulic engineers who have to tackle many a problem in daily life, and who will not always find an appropriate solution. Each chapter is introduced with a summary to outline the contents. To illustrate application of the theory, examples are presented to explain the computational procedures. Further, to relate present knowledge to the history of hydraulics, some key dates on noteworthy hydraulicians are quoted. A historical note on the development of wastewater hydraulics is also added. References are given at the end of each chapter, and they are often helpful starting points for further reading. Each notation is defined when introduced, and listed alphabetically at the end of each chapter. This new edition includes in particular sideweirs with throttling pipes, drop shafts with an account on the two-phase flow features, as well as conduit choking due to direct or undular hydraulic jumps.

Dam Hydraulics
(Dam Hydraulics D. L. Vischer W. H. Hager VAW, ETH, Zurich...)
Dam Hydraulics D. L. Vischer W. H. Hager VAW, ETH, Zurich, Switzerland This book develops the main themes of water flow in dam structures, emphasizing the hydraulic principles governing the design, construction and refurbishment of dams. Opening with an overview of the various dam structures, it then develops fundamental topics including: reservoir sedimentation, waves due to landslides and dambreak waves. The authors provide a systematic analysis of the various phenomena associated with dam hydraulics, illustrated with appropriate figures and photographs of laboratory models and prototype structures.

Hydraulicians in Europe 1800-2000: Volume 2 (IAHR Monographs)
(More than 850 individuals partly forgotten by name, but s...)
More than 850 individuals partly forgotten by name, but sometimes found in historical writings, together with many well known or recently deceased persons are presented in terms of bio-data, short career highlights, and main advances made to the profession with a short biography of the main writings. If available, a portrait is also included. Hydraulicians in Europe, Volume 2 is a continuation of the first volume, both in outline and in coverage and pagination. Volumes 1 and 2 include more than 1500 biographies.
