Anti-corrosion methods for metal structures used in Gezhouba hydro project;

Research on filter in foundation drain hole of Gezhouba hydro project;

River Regime Regulating Works at Lower Reach of Gezhouba Hydroproject;

The construction and operation of Gezhouba hydroproject brought impact on the stage discharge relation during medium and low water period.

Gezhouba hydroproject was impounded and put into operation in 1981.

Comparative experiments of protection material for Yangtze River bed downstream of Gezhouba Project;

The river channel change, the bed load and bed material armoring, and the water level lowering after the operation of the Gezhouba project are analyzed based on the topographic and hydrologic data.

Application of RCC to longitudinal cofferdam and second stage works of Gaobazhou Project can not only simplify the river diversion works and shorten the construction time, but also save the cost and produce the electric energy ahead of schedule.

Gaobazhou Project is the reverse regulation reservoir of the upstream Geheyan project, and its flood control operation will be carried out in coordination with Geheyan reservoir.
