珠江枯水期压咸补淡骨干水库群水量调度研究

Scientific and proper water allocation of the middle and upper key reservoirs of the Pearl River and enhancement of the estuary's runoff function during low water period are not only important means to improve the abilities to allocate water resources and the optimal allocation of basin water resources, but also significant ways for the solution of water supply crisis during low water period of the Pearl River Delta. The purpose of this project is to establish a set of theory and method system about Pearl River key reservoir group water allocation during low water periods according to the practical work. The established theory and method system, provides feasible methods to describing the low runoff hydrologic characteristics in the Pearl River's water diversion district and understanding the rule of Pearl River key reservoir group water allocation. At the same time, it can give the decision proof to make plans for water allocation during low water periods and then water resources can exert more social, environmental and economic benefits. The study includes the theoretical and applied researches on Pearl River key reservoir group water allocation during low water periods.On theoretical researches, it mainly focuses on distributed low runoff forecast and the key reservoir group water allocation. On applied researches, it aims to use the measured historical data to verify the theoretical approaches. Finally, the theory and method system of Pearl River key reservoir group water allocation during low water periods is put forward.
