About the Author

Paulo Erbisti is a design engineer and a consultant with 45 years of experience working on various hydromechanical projects. This Brazilian engineer has contributed greatly to hydropower/dam engineering in the last 35 years in Brazil, Venezuela and in several other countries of the world as a result of his extensive consulting work. He has worked on a number of important project including Itaipu, Guri, Caruachi and Tocoma. In 2011, he was elected as one of twenty people believed to have made the biggest difference to the sector over the last decade by International Water Power & Dam Construction magazine.

Reviews

Nobody is better qualified than Professor Paulo Erbisti to have written this book “Design of Hydraulic Gates”, because he has acquired a very broad personal experience during his career devoted to hydroelectric projects, not only with a scientific spirit, but also a practical approach. He knows very well all the phases of implementation of hydromechanical equipment, from feasibility studies through to erection and commissioning, as well as rehabilitation. This book is extremely welcome as an efficient synthesis of a broad subject, and engineers from the various disciplines, not only mechanical and electrical but also civil engineers, will recognize its value. The author has covered the subject of gates very comprehensively in his book, from history to new developments. He discusses not only the principle of gates and their associated equipment, the choice of type and calculation methods, but also he (as an excellent practical engineer, who knows that `the devil hides in the details’) describes their construction details. Each chapter is supported by a complete list of international references. The book will be very useful for experienced engineers (as well as students) for the conception, construction and operation of gates.The interest of this book is evident as a reference, and Professor Erbisti should be gratefully acknowledged for his important contribution to this technology. Raymond Lafitte, Professor at EPFL (Federal Institute of Technology, Lausanne), President of the International Hydropower Association
As one leafs through the book, one is pleasantly surprised by the many clear illustrations and photos (ca. 300), tables (ca. 70) and calculations (ca. 20). […] On the one hand, the book – as a textbook – offers students a very clear introduction to the field and on the other hand, represents a handbook with lots of useful advice for engineers in the field of steel hydraulic engineering. Some 90 bibliographic references lead the reader to further background information, also in the realm of more theoretically oriented steel hydraulic engineering. Erbisti’s book "Design of Hydraulic Gates" is all in all a very useful and recommended book. Prof. Dr.-Ing. Gerhard Schmaußer, Aalen, in Stahlbau 73 (2004), 644-646
