Abstract: In this research, soil erosion and sediment yield were calculated by runoff shear
stress, runoff energy consumption and runoff power theory. Results indicated that a linear
relationship existed between the average runoff shear stress and sediment yield. Soil erodibility
in the experiment was 178.5g/(Pa·min), and the critical shear stress value was 0.54 Pa. Results
from energy consumption implied that there was also a linear relationship between sediment
transportation and energy consumption of runoff unit width: Dr = 14.61 (ΔE-0.37), which
indicated that the soil erodibility was 14.61g/J, with a critical energy consumption of
0.37J/(min·cm). Results from runoff power theory showed that sediment transportation
increased with increase in runoff power, and the simple linear relationship was also regressed: Y
= 8942.2x - 68.676. Generally, these three theories each showed certain advantages in describing
the soil erosion processes on the slope, among which the results from energy consumption
theory were simpler, more accurate, and proved more convenient in describing soil erosion on
the slope.
