Sediment Transport

---

Civilization and the economic development of a society are closely related to the ability to maximize the benefits and minimize the damage caused by rivers. A river freguently adjusts its cross-section, longitudinal profile, course of flow and pattern through the processes of sediment transport, scour and deposition. In order to sustain cultural and economic developments along a river, it is essentiai for us to understand the basic principles of sediment transport. These principles can be applied to the solution of engineering and environmental problems associated with natural events and human activities. The subject of sediment transport has been studizd for centuries bv engineers and river morphologists. Different approaches have been used to solve engineering problems. Results obtained from different approaches often differ drastically from cach other and from observations in the field. Some of the basic concepts, their limits of applications, and the interrelationships among them have become clear to us only in recent years. Many of the -complex aspects of sediment transport are yet to be understood, ang remain among the challenging subjects for future studies. Through years of research, teaching, engineering, and consultation work, I have studied different types of problems associated with sediment transport. Some of them reguire theoretical analyses. Some rely on empirica! methods. In many cases, a combination of theoretical and empirical approaches is needed. Sediment Transport: Theory and Practice is organized into the following cight chapters and four appendices: Chapter 1 Properties of Water and Sediment, Chapter 2 Incipient Motion Criteria and Applications, Chapter 3 Resistance to Flow and Bed Forms, Chapter 4 Bed-Load Transport, Chapter 5 Suspended Load Transport, Chapter 6 Total Load Transport Chapter 7 Comparison and Evaluation of Sediment Transport Functions. Each chapter addresses an important element of sediment transport, with self-contained material and examples. The material in each chapter is also related with that in preceding chapters, and lays the basis for theoretical derivaiions and applications in later chapters. For example, Chapter 1 provides the basic information needed for sediment transport computations in later chapters. The discussion of total load transport in Chapter 6 is closely related to the discussions of bed-load in Chapter 4 and of suspended load in Chapter 5. Most textbooks on sediment transport emphasize theories based mainly on the force approach. The sediment transport theories based on the energy or power approach have been largely ignored. This book provides in-depth coverage cf the mechaniss of sediment transport from the power approach. The book also gives a systematic analysis and comparison of transport theories based on the force approach. Authors of sediment transport textbooks are gpenerally reluctant to compare the strengths and weaknesses of different theories and formulas. Researchers and engineers often face the dilemma of selecting appropriate formulas for solving engineering problems. This book gives useful guidelines for the selection of formuias. Examples using field data provide step-by-step computational procedures for engineers to follow m solving practical ri' er engineering and environmental problems. Sediment Transport: Theory and Practice strives to achieve a balance between theory and practice. It is intended primarily as a textbook for engineering students. Suggested prereguisites for courses include calculus, differential eguattons, open channel hydraulics, and basic fluid mechanics. This book can also be used as a reference source for researchers and engineers to help in solving theoretical and practical problems in river engineering, river morpholopy, and river environmental sciences.
