Understanding the mechanism and behaviour of rivers flowing in alluvium is a most challenging subject. The conditions presented by a natural river are far from simple: the flow varies with location and time, and the granular structure and cohesive properties of the alluvium are rarely homogeneous. River Mechanics addresses this subject and aims to improve the understanding and formulation of the fluvial processes which occur in rivers. Topics covered include the interpretation of turbulence in the light of recent advances in the field, and current thinking on the regime concept.
For graduate students and researchers in hydraulic engineering, geomorphology, physical geography and other disciplines concerned with the behaviour and evolution of rivers. Also of interest to practising professionals.

@qu:The approach has a strong theoretical and experimental base, but is also cross-disciplinary: the author successfully integrates many useful ideas and formidable data compilations from the increasingly linked fields of hydraulic engineering, geology and fluvial geomorphology... This book is up to date and has a truly international perspective. @source:Nature @from:Yalin, M.S. @qu:A clear, coherent text, primarily intended for advanced students and research workers in hydraulic engineering, geomorphology and other disciplines concerned with the behaviour and evolutions of rivers. @source: @qu:"River Mechanics" by M.S. Yalin, consisting of five chapters with a total of 220 pages is highly appraized and shows special interest to the readers...the delicate figures and conciseness of illustration are found to be very helpful to the readers... "River Mechanics" provides a valuable and interesting reference for all working in the field of hydraulic engineering and the related disciplines, and people can benefit a lot from the book. @source:International Journal of Sediment Research
