Abstract: This paper collected and reorganized the calculation results of dam-breach flow of some hydropower stations in the power industry, and summarized and analyzed the current status of dam-breach flow calculation from the aspects of calculation methods and breach shape. The results showed that there were some problems in dam-breach flood analysis, such as improper selection of calculation methods and random assumption of dam breach shape. The suggestions provided in this paper could be used as a reference for dam breach analysis and research in similar projects.

Key words: hydropower station, dam-break flow calculation, breach shape
