Oscar Castro-Orgaz is a Professor of Hydraulic Engineering at the University of Córdoba, Spain. He has written more than 50 papers in peer-reviewed journals of hydraulics and fluid mechanics and serves as reviewer for the main journals on these topics. He is also Associate Editor of the Journal of Hydraulic Engineering ASCE, and Editorial Board Member of Environmental Fluid Mechanics, Springer. Willi H. Hager is Professor of Hydraulics at the Swiss Federal Institute of Technology, ETHZ. He has written more than 500 papers, of which more than half in peer-reviewed journal, mainly on open channel flows, pipe flows, scour, erosion, impulse waves, wastewater hydraulics and supercritical flows. He also wrote more than 20 books in these topics. He served from 2006 to 2011 as Editor of the Journal of Hydraulic Research, and was the recipient of various international awards.

“Non-Hydrostatic Free Surface Flows … is an exceptional book that masterfully takes the reader on a brave voyage into a universe of Free-Surface Flows that do not presume a hydrostatic pressure distribution in the vertical direction. … The wealth of information amassed in this text is extraordinary. Both students and researchers will find that the quality of the presentation is outstanding, and the didactic value of the text is unparalleled.” (Nikolaos D. Katopodes, Journal of Hydraulic Engineering, Vol. 147 (10), 2021)“‘Nonhydrostatic free surface flows’ is an excellent book that merits having a place on the shelves of any person dedicated to any discipline in which the flow of water might be fundamental, from ecology to civil engineering.” (Juan V. Giraldez, Environmental Fluid Mechanics, Vol. 19, 2019)“This is the first free surface hydraulics book dedicated to Boussinesq’s theory since Boussinesq’s 1877 book. The book contains a clear presentation of basic theoretical aspects. It is carefully illustrated and edited. … Non-hydrostatic free surface flows is a valuable addition to the literature, containing information that will be of great interest for students, researchers and professors working in open channel hydraulics.” (Takashi Hosoda, Journal of Hydraulic Research, April, 2018)
