Comparison of the Reynolds number Re between seven types of litter layer. Re is the Reynolds number of the water flow; N1–N7 are treatments, see Table 2 for treatment specifics; T1 is slope 5°, rain intensity 60 mm·h⁻¹; T2 is slope 10°, rain intensity 60 mm·h⁻¹; T3 is slope 5°, rain intensity 120 mm·h⁻¹; T4 is slope 10°, rain intensity 120 mm·h⁻¹. Error bars indicate standard deviation.
