[Abstract]
Taking the risk instability of inverted siphon in the water diversion project as the research objective, considering the complex and dynamic relationship between the four factors such as nature, engineering,man-made and management, a risk analysis feedback model based on system dynamics was established. The importance of factor which may affect the stability of the inverted siphon project was analyzed. The results of the analytic hierarchy process were used to validate the feedback model. The results showed that the model had good accuracy and applicability, which may provide a new way for risk assessment of water diversion projects in the future.
