In order to investigate whether or not the debris flow will harm in dam site and assessing the effect on the construction of dam, the survey about Jieyipo debris flows is well done in field. The character of terrain、geology condition、vegetation、debris flow trail erosion and silt feature in vale are fully cognized. Simultaneously, some experiments and meter age about the vale and debris flow fans have been practiced. Based on the formula about dilute debris flow, the velocity of flow、runoff and wallop of Jieyipo debris flow are computed. All of these works offer the basic evidences for the assessment of geological hazard about debris flow. The surveys shows that the activity of Jieyipo debris flow is overblown, however, the soil and water conservation in the catchment areas should be strengthened, especially focused on the exposed sloping field in the entrance.
