Turbulence in Open Channel and River Flows covers turbulence and related fluid mechanics in open-channel flows, addressing both basic mechanisms and their applications. It helps readers understand the organized motion involved in turbulent flow and apply this understanding to the practice of hydraulic engineering, including mass and sediment transport.
Chapters cover mathematical expansion procedures and basic fluid mechanics to help readers understand essentially physical phenomena, and present special techniques for measurement and accurate direct observation of open-channel turbulence in laboratory flumes or natural rivers. Topics related to environmental management and turbulence-related disasters are addressed.
- Includes detailed mathematical expansions and supporting supplements in an appendix
- Presents the mathematics and fluid mechanics needed to understand turbulence in open channels
- Includes experimental topics from the author’s research, encouraging readers to measure and accurately observe turbulence in laboratories and rivers
The book is ideal for graduate students, researchers and engineers in hydraulics and hydromechanics.

Biography
Michio Sanjo was awarded a doctor’s degree in 2003 from Kyoto University under Prof. Iehisa Nezu. He has been working on hydraulics as an associate professor at Kyoto University for years. He specializes in the experimental investigations of turbulence phenomena in open-channel flows, such as the secondary currents, horizontal vortex, free-surface divergence, gas transfer and influence of bottom roughness. Further, He conducted field works with development of the autonomous robot boat for automatic velocity measurement in river.
The work is comprehensive in its coverage and relatively easy to follow for a reader with some previous fluid mechanics/hydraulics background.
