Book Reviews
Prof D.H. PEREGRINE, in Jl of Fluid Mech., 2006, Vol. 557, p. 473.
"Throughout the book the author’s enthusiasm for his subject shows. Overall, the book  lives up to its title. It forms a good introduction for an advanced undergraduate, or graduate student, and a guide to further information for practitioner." (Book review at EprintsUQ) (Full review)
Dr M. WILSON, in Intl Jl River Basin Management, 2005, Vol. 3, No. 4, p. 297.
"Overall Environmental Hydraulics of Open Channel Flows is a well written, clear and concise book which will serve the intendend audience. It contains numerous diagrams and photographs to illustrate key points. It stands alone from Hydraulics of Open Channel Flow: an Introduction, unless the reader does not already have a basic grounding in hydraulics."
Prof D.A. LYN, in Environmental Fluid Mechanics, 2005, pp. 987-391.
"This book contains some useful material for different courses, and may provide an elementary reference."

Hubert CHANSON is a Professor in Civil Engineering, Hydraulic Engineering and Applied Fluid Mechanics, at the University of Queeensland, Australia. His research interests include design of hydraulic structures, experimental investigations of two-phase flows, coastal hydrodynamics, water quality modelling, environmental management and natural resources. He has been an active consultant for both governmental agencies and private organisations. His publication record includes over 550 international refereed papers and his work was cited over 2,700 times since 1990. Hubert Chanson is the author of several books : "Hydraulic Design of Stepped Cascades, Channels, Weirs and Spillways" (Pergamon, 1995), "Air Bubble Entrainment in Free-Surface Turbulent Shear Flows" (Academic Press, 1997), "The Hydraulics of Open Channel Flow : An Introduction" (Butterworth-Heinemann, 1st edition 1999, 2nd editon 2004), "The Hydraulics of Stepped Chutes and Spillways" (Balkema, 2001), "Environmental Hydraulics of Open Channel Flows" (Butterworth-Heinemann, 2004), "Applied Hydrodynamics: an Introduction of Ideal and Real Fluid Flows" (CRC Press, 2009), and "Tidal Bores, Aegir, Eagre, Mascaret, Pororoca: Theory And Observations" (World Scientific, 2011).
