With the model test,the comparative studies of energy dissipation effect of the aeration splitter pier on the surface spillway and the conventional sources on the cushion pool were conducted in this paper.

When flaring gate piers are on surface spillways in high arch dam,the dispersion of plunging jets from surface spillways is closely related to the charateristics of flow.

The situation of leak in floodgate of Lushi water project is introduced, cause and the urgency of it is analyzed.

The application of plywood/squared timber formwork in sluice concreting of Suzhi hydropower project;

Multi-objective and multiple fuzzy optimization of sluice scheme in north conveyance canal head

Therefore, after detailed studies of the above influence factors,the paper establishes the index eval uation system,and applies many models to the sluice optimum scheme of BeiyinQushou project.

Design of stilling basin for spillway gate of Kangyang hydropower station on the Yellow River;

After introducing the design, debugging, and operation of the spillway gate monitoring & control system at the Fuchunjiang Hydropower Plant, this paper indicates the functions of this system.

The theoretical model and the calculation method for the control of the spillway gate in the reservoirs are studied, and a new model for the optimization procedure of the dynamical tracking of practical spillway flow is developed.

This paper briefly introduces the present status of the spillway gate,the structure and features of the reformed computer monitoring & control system and the reformation of rolling bearing at the fixed roller gate in the Penglatan hydropower plant.
