| 摘 要： | 1 INTRODUCTION There are three basic energy dissipation rate approaches used for the derivation of sediment transport functions. They are the gravitational power theory by Velikanov (1954), the stream power theory by Bagnold (1966), and the unit stream power theory by Yang (1973, 1979, 1984, and 1986). The theoretical basis of these approaches has been summarized by Yang (1996) in his book, Sediment Transport Theory and Practice. Yang also made comparisons of the three basic approa…

| Abstract: | This paper provides a step-by-step derivation of the sediment transport functions by Engelund and Hansen (1967) and by Ackers and White (1973). The theoretical derivations demonstrate that these two functions are closely related to Bagnold's (1966) stream power and efficiency concepts. |
