Description
Book SynopsisA stream flowing in alluvium deforms its bed surface, forming ripples, dunes, bars, etc., and, in many instances, it deforms its channel entirely, thereby creating meandering or braiding patterns. It could be said that, in general, an alluvial stream and its deformable boundary undergo a variety of fluvial processes leading to the emergence of a multitude of alluvial forms.
This book concerns the physics and analytical treatment of various fluvial processes and the associated alluvial bed and plan forms listed above. Following an introductory chapter on the basics of turbulent flow and sediment transport, the book covers the origin, geometric characteristics and effects of bed forms, from small- to meso-scale (ripples, dunes, alternate and multiple bars); the initiation, geometry and mechanics of meandering streams; the computation of flow, bed deformation and the planimetric evolution of meandering streams; and braiding and delta formation. The book also covers the regime con
Trade Review
"From fundamental hydraulic principles to recent finding on alluvial channel formation and evolution, this monograph thoroughly reviews the hydraulics, sediment characteristics, and engineering relationships that lead to our current understanding of fluvial processes and geomorphic features in the landscape. Unifying the pioneering work of professor Yalin with the contemporary research of professor da Silva, the revised monograph includes recent lab and theoretical advances in open channel hydraulics, coherent flow structures, resistance of bedforms, application of thermodynamic principles to alluvial systems, as well as the formation and maintenance of regime channels.
Professor da Silva takes on the many complex issues of open channel flow and presents them in an elegant and approachable manner, with mathematical relations and excellent illustrations that develop the respective topics. Given the vast experimental findings of the authors’ research, each chapter includes the authors’ perspective and remarks that range from pragmatic application of principles to theoretical specifics that should not be overlooked.
This is an excellent reference for graduate students, instructors, and active researchers in the fields of fluid mechanics, hydraulic engineering, sedimentation, and fluvial geomorphology that is applicable to experimental and field based research. The monograph includes thorough references to both previous findings in the literature as well as sources of data for a range of fluvial research topics. Additionally, each chapter contains thought provoking problem sets for educational applications. Overall, this monograph is a great library addition for anyone working in fluvial systems."
