Abstr：Risks in a construction and diversion system of hydropower project with cascaded reservoirs depend on the flood control of upstream reservoirs and downstream reservoir operation and environmental control. This paper develops a diversion risk evaluation model that simulates flood discharge process to couple the major factors, such as upstream water release, interval-basin flood, branch afflux, and construction of upstream and downstream stations, upstream reservoir regulation, river channel storage, and uncertainties in natural flood, upstream station discharge capacity, branch afflux and its superposition method, interval-basin flood, downstream reservoir backwater level, and construction diversion system. This model uses Monte-Carlo Method to evaluate diversion risk. The present study provides references for the decisions on the diversion standard of Baihetan project on the lower Jinsha River.
