Study on Flood Pre-Discharged Rule-Making for Xihe Reservoir Flood Control

Abstract:

In order to increase power generation of hydropower station,a higher flood control level was favorable for most of the hydropower station in flood season,but this could bring about high risk for reservoir operation sometimes.Taken Xihe reservoir for example in this paper,by analyzing the long series of the flood characters on damsite,storage and discharge capability of the reservoir,a feasible flood control level was put forward in the premise of ensuring flood control safety.Moreover,the pre-discharged rule was figured out on the basis of formulated pre-discharged index,pre-discharged flow and scheme comparison, finally, the safety of the rule application was confirmed by flood routing.It is expected that more power could be generated in flood season as a result of risen water level before the dam.
