Abstract: As the "major force" of flood control regulation, the reservoirs in middle and upper reaches of Changjiang River have gained remarkable flood control benefits in recent years. As the last defense line of the comprehensive flood control system, the flood storage and detention area is the final means to properly arrange the excess flood volume of the Changjiang River. On the basis of sorting out the flood control objectives and tasks of the controlling reservoirs on the upper and middle reaches of the Changjiang River and the flood storage and detention areas in the middle and lower reaches, combined with the standard regulations and the current real-time forecast and operation level, a joint operation strategy of water projects is proposed to prevent the 1954 flood under the current conditions. Through the construction of water projects operation integrated model, the whole process of 1954 flood is simulated and the simulation effect is analyzed. The results show that based on the proposed joint operation strategy of water conservancy projects in the upper and middle reaches of Changjiang River, the total flood storage volume is 22.8 billion m3, and the water level of the main control stations is basically effectively controlled near or below the target water level, a good practical test has been achieved in dealing with the flood simulation operation in 1954.This strategy can provide reference for the joint operation of reservoir groups and flood storage and detention areas in the Changjiang River Basin.
