Study on dynamic characteristics of slope erosion under natural rainfall conditions.
Journal of Shenyang Agricultural University（2010）
摘要
The experiment is to study dynamic characteristics of slope erosion under natural rainfall conditions by observing the slope under natural rainfall runoff velocity.The results showed that the Reynolds number and the Froude number of the slope coverd by vegetation and bare increased with the increase of rainfall intensity.The drag coefficient decreased with the rainfall intensity.the Reynolds number and the Froude number of the slope coverd by vegetation changed in relatively stable with the rainfall intensity.
