Several articles (Carollo et al, 2021; Di Stefano et al, 2018; Di Stefano et al, 2019 a & b; Di Stefano et al, 2020; Nicosia et al, 2019; Nicosia et al, 2020 a, b & c; Palmeri et al, 2019) have been published recently that claim to show a meaningful relationship between the measured hydraulic variables taken from a series of independent overland flow and rill flow measurements. These papers insert the experimental data into a relationship between Darcy-Weisbach roughness and other hydraulic variables, including the flow Reynolds and Froude numbers. The resulting exceptionally high correlation coefficient is claimed to show a meaningful general relationship.It is argued here that the authors have inadvertently derived a relationship that is, instead, an example of spurious correlation (Brett, 1996) in that the two variables regressed are strongly interdependent, both, to a large extent, derived from the same underlying hydraulic variables. As a result, any reasonable (or unreasonable) set of variables chosen at random will generate the same excellent correlation, providing no new insight into the relationships between the measured variables
