摘要：
The supersaturated total dissolved gas (TDG) generated during high dam spills may cause gas bubble disease for fish and ultimately endanger their existence. As more and more high-dam hydropower projects have been constructed in China, the environmental assessment of the supersaturated TDG is becoming more and more important. It is of great importance for quantitative impact assessment of the supersaturated TDG of high dams and for the construction of ecological friendly high-dam hydropower projects. Based on the conceptual summarization of the TDG production process, the TDG prediction model for high-dam projects, in which the ski-jump energy dissipation is adopted, is developed in the paper. The model is validated by field data and employed in the TDG prediction of a high-dam hydropower project to be built in southwest China.
