Comment on “Determining soil erodibility for the USLE-MM rainfall erosion model by P.I.A. Kinnell”

In this comment, using the database of Sparacia experimental area, both this geographical independence and the linearity hypothesis between soil erodibilities were tested. The linearity hypothesis was not completely consistent for Sparacia experimental area while it was more satisfied for the comparison between soil erodibility of USLE-MB and USLE-M. The exponential equation proposed by Kinnell (2018) between the power of erosivity term and the coefficient of proportionality was demonstrated to be site-dependent.
