Addendum to “Quantifying Uncertainty in Tracer‐Based Hydrograph Separations” for Three‐Component Mixing Problems

Abstract

Water mixing problems have long been studied in hydrology, and Genereux (1998) presents an approach that is widely used to estimate uncertainty when chemical or isotopic tracers are used to quantify the mixing of two different waters or "components" (e.g.,

On (in)validating environmental models. 2. Implementation of a Turing‐like test to modelling hydrological processes

“…Indeed, such surface soil moisture estimates have often rather been used for data assimilation to correct for model deficiencies (see e.g., the recent review of Babaeian et al, 2019). Environmental tracer data might be useful in testing different model structures (e.g., Benettin et al, 2015; Harman, 2015; Kirchner, 2016; McMillan, Tetzlaff, et al, 2012; Rinaldo et al, 2015; Stadnyk and Holmes, 2020; Vaché & McDonnell, 2006) but might require more parameters in a model to make proper use of it and a proper consideration of uncertainties in any flow separations (e.g., Genereux, 2022; Joerin et al, 2002; Kirchner, 2019). This is even more the case for non‐conservative water quality data (e.g., Hollaway et al, 2018; Strömqvist et al, 2012).…”
