Description :
This paper presents a comparison of different fractional bed-material load computation methods in sand-bed channels. These methods include the direct computation by size fraction approach of Einstein, Laursen and Toffaleti; the bed material fraction (BMF) approach using equations of Engelund and Hansen, Ackers and White, Yang, and Karim's modified BMF method; and the transport capacity fraction (TCF) approach. Statistical analysis and graphical comparison are utilized to demonstrate the performance and variations in different methods.
