一种考虑鱼类在库区内洄游需求的水库调度方法
By optimizing reservoir scheduling parameters through pulsed flow discharge during the fish migration period, the problems of low fish migration success rate and reduced water supply guarantee rate were solved, achieving a balance between fish migration demand and reservoir water supply.

AI Technical Summary
Existing reservoir management methods have failed to effectively meet the migration needs of fish within the reservoir area, resulting in a low migration success rate. At the same time, increasing the flow velocity in the reservoir area in the long term to meet the migration needs of fish will significantly reduce the water supply guarantee rate of the reservoir.
By introducing two technical parameters—the starting water level and the starting flow rate of the migration channel—and combining the needs of fish migration and reservoir water supply, a pulsed flow discharge method is adopted to increase the flow velocity during the fish migration period, thereby optimizing reservoir scheduling parameters to balance fish migration and water supply needs.
This approach achieves the goal of increasing flow velocity during fish migration to ensure successful migration, while maximizing the reservoir's water supply guarantee rate and avoiding the negative impact of long-term increases in flow velocity on the water supply rate.
