Study on flood control projects joint flood control operation of The Daqing river basin

Abstract

Abstract Baiyangdian Lake is an important pivotal project in the Daqing River Basin. The research on the joint flood control operation of water projects in the Daqing River Basin seems particularly important as higher requirements have been set for the flood control in the basin based on the construction of the Xiong’an New Area. In this paper, a joint flood control operation model was set up and solved with the joint flood control operation objective of minimizing the highest water level of Baiyangdian Lake. A study on the joint flood control operation under different flood conditions was carried out under the premise of ensuring the safety of reservoir projects. The optimal operation can ensure that the Wen’anwa flood storage and detention area will not be opened in the event of a hundred-year flood, reduce the highest water level of Baiyangdian Lake to a certain extent, effectively alleviate the pressure on the flood control of dikes and Baiyangdian Lake and provide support for guaranteeing the flood control safety of the Xiong’an New Area.
