Understanding the processes of interrill and rill erosion is necessary to develop soil erosion prediction models.However,it is difficult to obtain the information using traditional monitoring techniques.In the study,considering deposition at the base of slope area,7Be was used as a tracer to describe the interrill and rill erosion dynamic during a simulated rainfall event in a slope farmland with a gradient of 25°.The results indicated that the appearance time of significant rill calculated by7Be content of...
