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.

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.

Due to the increase of water pumpage and the sand excavation at the river bed,the groundwater table became declined and water quality degraded in Dongwu water sources area,Tai\'an City.

State of Water Quality and Its Influencing Factors in Dongzhen Reservoir;

The main limited factors of nutritive salt,water-chemistry factors,plankton and primary productivity in Donghu reservoir were studied.

45 kinds of plankton were found in Donghu reservoir, in which 28 kinds were phytoplankton species(genera),and 17 kinds were zooplankton species(genera).

Application of machine with chain for excavation trough to closure construction in Dongfeng reservoir;

Concentration of dissolved gaseous mercury (DGM) in water profile were determined during various seasons in Wujiangdu Reservoir and Dongfeng Reservoir, two typical hydroelectric reservoirs both located on the up-mid stream of Wujiang River.
