Wainwright et al. (2008) state that ‘For example, Kinnell (1993) suggests that there should be a peak in detachment at flow depths of two raindrop diameters with lower detachment rates at lesser and greater flow depths, although the data to support his case are also woefully limited in that there are no data to support the initial rise in detachment, other than fitting a point at the origin, which is an artifact of considering sediment concentration in the flow.’ This statement results from incorrectly interpreting the role of the empirical flow depth–drop size function presented in Kinnell (1993). The focus of Kinnell (1993) is sediment transport of particles traveling by raindrop induced saltation within flowing water. The primary equation considered in Kinnell (1993) was:
