Abstract: This paper addresses the issue encountered during flood regulation at a hydropower station, where failure of flood discharge facilities prevents gate operation in accordance with the principle of "synchronous and symmetrical opening". Based on hydraulic model test results, emergency gate opera ⁃ tion schemes are formulated. Through flood routing calculations, emergency gate operation schemes un ⁃ der specific incident scenarios are proposed while ensuring that flood control characteristic water levels do not exceed the designed values. The results indicate that the recommended scheme can maintain ef⁃ fective discharge capacity under the condition of one shallow outlet failure, meeting flood control safety requirements. The findings of this study can provide technical references for emergency regulation of similar reservoirs.
