Table 2. Soil loss rates (g m-2min-1) in each section during the 45-60 min periods in the tarp and screen treatment on the 18 % slope in the Zhang(2019) experiments estimated using the scheme shown in Figure 4 and Eq. 4. The results for the screen experiments using the scheme shown in Figure 4 assume that the relative contributions of the sections to sediment discharges in the screen experiments follow the same spatial pattern as observed in the tarp experiments. No data exists to determine the actual soil loss rates directly in the screen experiments.
