- Abstract:
- To study the regulation of Jag C162 on flow shear stress on the loess slope, the chemical regulation of surface water and sediment process were monitored under two continuous simulated rainfall experiments with the rainfall intensities of 2.0 mm/min, slopes of 20°, Jag C162 dosage of 1, 3, 5 g/m2 in way of spraying. The main results are as follows. (1) On two simulated rainfall experiments, the flow shear stress of bare slope and slope with spraying different doses of Jag C162 first increase, and then presented the stability, and the processes could be described by the logarithmic equation. The variation values of flow shear stress of bare slope are greater than those of flow shear stress of slope with spraying different doses of Jag C162, the runoff yields on the slope with spraying different doses of Jag C162 were later than those on the bare slope, and the initial of stable trend on the slope with spraying different doses of Jag C162 was also later than the bare slope. (2) In the process of continuous rainfall, Jag C162 could reduce the flow shear stress on slope surface, and significantly narrow the difference of shear stress between two rainfall events; with Jag C162 doses increasing, the effects of Jag C162 on the slope surface shear stress enhanced. (3) Considering the influence of Jag C162 on reducing flow shear stress on slope surface, Jag C162 dose of 5 g/m2 was recommended to research regulation of Jag C162 on the slope surface flow hydraulic parameters, and control the soil erosion on loess slope.
