Fluvial Processes (2nd Edition)

Description

A 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 concept, the time-development of a stream towards its regime state, and the formulation of stable, or equilibrium, morphology. The book distinguishes itself by its comprehensive analysis and discussion of key processes involved in large-scale river morphodynamics.

The book was written primarily for researchers and graduate students of hydraulic engineering, water resources and related branches of earth sciences, but it will also prove useful for river engineers and managers.

Author(s) Biography

Ana Maria Ferreira da Silva obtained her first degree in Civil Engineering from the University of Oporto, Portugal, in 1985. For the next three years she worked as a Research Officer for the Hydraulics Division of the National Laboratory of Civil Engineering (LNEC), Lisbon, Portugal. She moved to Canada in 1989, where she obtained her M.Sc. and Ph.D. degrees also in Civil Engineering from Queen’s University at Kingston, Ontario, in 1991 and 1995, respectively.

M. Selim Yalin obtained his Civil Engineering Diploma in 1950 and his Ph.D. degree in 1953, both from the Technical University of Istanbul. After completing his military service in Turkey, he moved to Karlsruhe, Germany, where he held the positions of Scientific Collaborator at the Institute of Hydraulic Engineering of the Technical University of Karlsruhe (1955-1956), and Research Officer at the German Federal Waterways Engineering and Research Institute, BAW (1956-1960).
