Study on Dynamic Flood Limit Water Level at Wudu Reservoir;

The formation section of Wudu reservoir area, whose dam belongs to gravity dam, locates at the northern drape zone of Longmen mountain.

According to the statistical characteristics of inflow flood in Dongwushi reservoir from 1951 to 2000,seasonal AR(1) model was first used to simulate the reservoir inflow flood,besides,some effects such as the uncertainty of flood discharge capacity,the different representative flood and the historical large flood were taken into account when adjusting the limited water level.

According to the Dongwushi reservoir design flood,with the reservoir′s flood prevention and flood control standards in principle,using dynamic programming methods,the Dongwushi reservoir flood control model is established,the Dongwushi reservoir and its downstream targets of the protection of flood control scheduling programme are got.
