"The book constitutes an excellent reference for the design engineer in search for clear guidelines; it i also extremely useful for introductory teaching purposes, by virtue of the exhaustive number of pictures, drawings and plots included. For the researcher, the book offers a list of more than 350 papers, reports, theses and books, where to look for more specific information. The Author has done a major contribution to the profession bringing together an impressive amount of information on the subject. Overall this a complete, attractive and profusely illustrated book about stepped chutes. Finally, it is my impression that this book is called to be a required reference to be read by those involved in the hydraulic design of stepped spillways and cascades."

"This book fullfils the need for presenting the state of the art in the stepped chute hydraulics. It helps students as well as practicing engineers and researchers get a feel for various aspects of the stepped chute analysis. [...] The book is very well illustrated with large number of charts and photographs. [...] Hydraulics of Stepped Chutes and Spillways is a useful contribution to the field of hydraulics."
