Based on the experiment of glass flume and the experiment of runoff scouring, the runoff velocity distribution on slope and the critical condition of rill erosion were researched.
通过玻璃水槽试验和径流冲刷试验，研究了坡面径流的流速分布和坡面细沟侵蚀发生的临界条件。

A direct calculation method of the critical shear stresses was established through observing initial place of slope erosion arising and the characteristic of runoff.
提出了一种用细沟在坡面发生的位置和相应的水流特性来直接计算土壤临界抗剪切应力的方法。
