Determination of the Sediment Carrying Capacity Based on Perturbed Theory

Table 3

The results of the error calculated by each formula in the natural rivers.

Formula	𝐸10% (%)	𝐸20% (%)	Average error (%)
Cao Formula	76%	88%	7.16%
Li Formula	31%	39%	37.66%
Zhang Formula	62%	73%	12.56%
A.-W. Formula	71%	82%	9.33%
E.-H. Formula	68%	79%	10.02%
Yang Formula	73%	85%	8.91%
Derived formula	88%	96%	4.05%

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.
