Determination of the Sediment Carrying Capacity Based on Perturbed Theory

Table 4

The results of the error calculated by each formula in the flume tests.

Formula	𝐸10% (%)	𝐸20% (%)	Average error (%)
Cao Formula	78%	90%	8.76%
Li Formula	69%	80%	9.86%
Zhang Formula	73%	83%	10.06%
A.-W. Formula	81%	90%	6.88%
E.-H. Formula	76%	88%	9.13%
Yang Formula	61%	70%	13.66%
Derived formula	85%	92%	4.57%

𝐸_10% represents the percentage of scatters in which the error is less than 10% of measured data in the natural rivers; 𝐸_20% represents the percentage of scatters in which the error is less than 20% of measured data in the natural rivers.
