TRANSPORT OF GRAVELS WITH DIFFERENT RANGES OF GRAIN SIZES IN A STEEP CHANNEL
《International Journal of Sediment Research》2005年第2期143-155,共13页Jau-Yau LU Chih-Chiang SU 
An understanding of the transport mechanism of gravel-bed rivers is very important for the river management and engineering works. The main objective of this study was to conduct a series of laboratory experiment in a...

MOVEMENT OF GRADED SEDIMENT WITH DIFFERENT SIZE RANGES
《International Journal of Sediment Research》1999年第3期16-29,共14页冯勇 安澄全 李涛 
Bagnold's empirical correlation is one of the most applicable bed load relationships in the literature. However, few drawbacks still exist in Bagnold's correlation. In this study, a modified Bagnold's formula was pr...
