Preface

It is my pleasure to write the preface of the book “Sediment Transport - Flow and
Morphological Processes” published by Intech Open Access Publisher. The transport
of sediment in the turbulent flow comprises of complex phenomena. Although
sediment transport due to water flow is directly related with long-term and short-term
alteration of the earth's surface, which has significance in science, engineering and
environmental applications, up until now the scientific progress in quantifying the
relevant processes has been rather slow. This explains the reason for abundance of
empiricism and independent field observations in this discipline. It has been several
decades since the advent of our understanding on micro-level turbulence properties of
fluid flows that we have started to apply our knowledge on turbulence for transport in
geophysical boundary layers.
Intech Open Access Publisher has taken a good step to publish a series of books on the
issues of sediment transport. The participation to the current book is by special
invitation to authors selected based on their previous contributions in recognized
scientific journals. Consequently, contents of the chapters are the reflections of the
authors’ research thoughts.
This book provides indications on current knowledge, research and applications of
sediment transport processes. The first three chapters of the book present basic and
advanced knowledge on flow mechanisms and transport. These are followed by
examples of modeling efforts and individual case studies on erosion-deposition and
their environmental consequences. I believe that the materials of this book would help
a wide range of readers to update their insight on fluvial transport processes.
Finally, I would like to thank Intech Open Access Publisher for inviting me to
contribute as a book editor. Special thanks are also due to the Publishing Process
Manager for her cooperation and help during preparation of the book.
