Abstract：The basic problems in optimizing the layout of flood control engineering system,arranging flood outlet and improving the flood control capacity of river basin are the understanding of the change of hydrological regime,the identification of flood risk and the coordination of flood control standards in the changing environment.According to the new situation of flood control in the Pearl River Basin,the present situation and shortcomings of related methods of design flood prediction and flood risk assessment are analyzed.Based on the hydrological dynamic model and the changing environment of the designed rainfall,the design flood prediction method is preliminarily discussed,and the refined flood risk identification method considering the flood channel is proposed,and how to coordinate the upstream and downstream of the river basin and achieve the coordinated improvement of flood control standards is preliminarily elaborated,in order to provide reference for the flood control planning of the Pearl River Basin under the new situation.
