Here θb is the soil water content (cm3 cm−3
) right after the rainfall
event, θa is the antecedent soil water content (cm3 cm−3
), DE is the
depth of soil profile (700 mm).
In order to evaluate the effects of soil managements (SMs, including
BM, BMWC, BMT and ST) on surface runoff and sediment reduction in
comparison to NC, we calculated the runoff reduction (RR) and sediment
reduction (SR) under the studied SM treatments by (Zhao et al.,
2013c):
