This textbook discusses the fundamental principles of sediment transport in the geophysical context of rivers and is intended as both a course textbook and as a guide for the practical engineer. We begin by describing phenomena such as bed load and suspension transport from a classical perspective by applying the mean wall shear stress approach while additionally incorporating a statistical description of the inherent wall shear stress fluctuations. Concepts from turbulent flow regime are introduced to address the limitations of the classical approach to various aspects of sediment transport, such as for example, the Newtonian description of dense suspensions, or the description of the self-organization processes for developing bed forms, or the prediction of transport in very rough bed conditions. In this context coherent structures and flow separation mechanisms are developed as important new elements, which allow using topological rules for the formulation of transport especially for developing bed forms.
Since the most up-to-date research findings in the field are presented, this book serves as both a support in the formulation of academic research programs, and as a practical text for engineers seeking to simulate complex problems or special aspects of sediment transport. This book will therefore be of interest and of use to both students and to the professional scientist.

From the reviews: "Sediment transport is a multidisciplinary science, and proper understanding of the sediment-transport phenomenon in solving real-life problems involves very active collaboration between physicists, engineers, mathematicians, statisticians and geologists. ! The book is very well written with plenty of illustrations. ! I sincerely believe that this book will be extremely helpful for advanced undergraduates, graduates and researchers of sediment transport. I strongly recommend the book for the libraries of all universities/institutions." (Rajat Mazumder, Journal of Sedimentary Research, January, 2007) "The book discusses the fundamental principles of sediment in the geophysical context of rivers. Different approaches to modeling the sediment transport are presented. ! The book reflects most up-to-date research in the field. It may be used both as a course textbook, and as a guide for practical engineers." (llya A. Chernov, Zentralblatt MATH, Vol. 1105 (7), 2007) "The study of sediment transport is complex, and in this book the authors aim to bring together the most recent research with which to present the updated theories of sediment transport. ! the book to be a course textbook as well as a manual for engineers. ! On the whole, the book accomplishes what it set out to do: present the most up-to-date theories of sediment transport." (C. E. L. Thompson, Geological Magazine, Vol. 145 (3), 2008)
