- •
An alternative method to estimate the uncertainty in discharge measurements.
- •
It improves the estimation of cross-sectional interpolation errors.
- •
Link between the interpolation errors and the study of high-resolution gauging.
- •
The uncertainty component is estimated through an original subsampling method.
- •
A sampling quality index (SQI) is suggested.
- •
An analog approach includes riverbed shape and flow distribution complexity.
