Short summary
We examine rainfall-induced change in soil microroughness of bare soil surfaces in agricultural landscapes with initial microroughness length scales on the order of 2 mm (smooth surfaces). Past studies have focused on scales of 5–50 mm and have reported a decrease in miccroroughness. Findings in this study show a consistent increase in microroughness under rainfall action for initial length scales of 2 mm. Thus, rainfall–surface interactions can be different for smooth and rough surfaces.
