Comment on “Review of methods of spatio-temporal evaluation of rainfall erosivity and their correct application” by Brychta et al. (2022), Catena 217, 106454Bezak, Nejc (Avtor) Chen, Walter (Avtor) R factorrainfall erosivitysoil erosionUSLE-type modelmodified Fournier indexThe review study conducted by Brychta et al. (2022) is very informative. It provides an excellent overview of the approaches that can be used for the spatio-temporal assessment of rainfall erosivity. The authors also emphasized the importance of applying regression equations to the physio-geographic conditions for which they were developed. However, the study’s authors incorrectly cited the source of one of the empirical equations shown in Table 1. In addition, only a portion of the original equations was presented. Consequently, applying this particular equation with insufficient information could result in estimations of rainfall erosivity that are erroneous or biased. Hence, researchers should always double-check the applied equations in the original sources.20232023-05-25 13:45:30Članek v reviji146373UDK: 556.1ISSN pri članku: 0341-8162DOI: 10.1016/j.catena.2023.106934COBISS_ID: 139045891sl
