In the watershed, the sediment yield, accumulation and outflow for the two terms are very important issues. That is watershed planning and governance to prevent sediment disasters. In this study, in order to the river Zengwun as an object, try to establish a relationship watershed sediment budget. Then, for moving sediment and sediment budget model validation tests performed. This part can be used to determine the feasibility of sediment budget model. Finally, the actual analysis of the sediment budget, you can assess the damage type of sediment deposition.
