| Abstract: | The dynamics characteristic is summed through analyzing the conformation of slope surface flow, and the soil erosion mechanism is summarized comparing the research of critical erosion slope. The velocity, sediment concentrations of slope surface flow and soil surface characteristics act mutually, and these relationship can be understood only when the velocity and sediment concentration is measured timely , precisely and dynamically. |
