Figure 3.24 Comparison of sediment transport formulas (Brownlie, 1981).
Figure 3.25 Comparison of sediment transport formulas (Woo and Yoo, 1991).
The author tested the Wu et al . (2000b) formula, the modified Ackers-White for-
mula (Proffitt and Sutherland, 1983), the modified Zhang formula (Wu and Li, 1992),
the Karim (1998) formula, and the SEDTRA module for fractional bed-material load.
Because the modified Zhang formula is only for the fractional discharge of suspended
load, it was combined with Eq. (3.80) to obtain the fractional discharge of bed-material
load. The non-uniform sediment data collected by Toffaletti (1968) were used, includ-
ing experimental data observed by Nomicos, Einstein-Chien, and Vanoni-Brooks, and
field data in the Rio Grande, Middle Loup, Niobrara, and Mississippi Rivers. In order
