| Abstract: | Based on the integral model experiment, the different conditions of the main dam’s flood-discharge gate of Shahe Reservoir in terms of the flow state, the ratio of energy dissipation, and the length after plunge are tested in the context of original size and altered length level of plunge pool, and the conclusions that the optimal result of flow state and energy dissipation could be achieved in the situation of the plunge pool extended by four meters and the diffusion length shortened by four meters accordingly are drawn as well. |
