The risk evaluation of the hydraulic structure of small hydropower stations is a subject seldom covered,It has a positive guiding significance for the security renovation of small hydropower stations.In this paper,the authors made some improvements based on the comprehensive risk index method proposed by Portugese,Various factors affecting the safety of small hydropower statipons,including engineering structures,operation and management,failure consequences and surroundings are considered comprehensively.The model of small hydropower hydraulic structure risk assessment is established.To improve the reliability of the results of model calculation,experts' views are dealt with by the transfer entropy theory.Finally,it gives an example to confirm this practical and scientific method.
