Study on flood control operation of Jinsha River cascade reservoirs combined with the Three Gorges along the Yangtze River

The middle and lower reaches of the Yangtze River were the main flood control points of the Yangtze River Basin, which had greatly improved after the completion and operation of the Three Gorges and Jinsha River cascade reservoirs. In order to enhance the flood control effect of those reservoirs, a combined operation rule named equal water storage method was studied in this paper, and taking the floods of 1954 and 1998 as examples, the flood control effect of cascade reservoirs was analysed. The results show that under the dispatching action of Jinsha River cascade reservoirs combined with the Three Gorges reservoir with this method, the excess flooding in Jingjiang area and Chenglingji area can be reduced, with better effect and practicality, which can be used in the flood controlling in the Changjiang river basin.
