| Summary: | <p>This technical note deals with the mathematical representation of
concentration–discharge relationships. We propose a two-sided affine power
scaling relationship (2S-APS) as an alternative to the classic one-sided
power scaling relationship (commonly known as “power law”). We also
discuss the identification of the parameters of the proposed relationship,
using an appropriate numerical criterion. The application of 2S-APS to the
high-frequency chemical time series of the Orgeval-ORACLE observatory is
presented here (in calibration and validation mode): it yields better results for
several solutes and for electrical conductivity in comparison with the power
law relationship.</p> |
