| Abstract: | The shapes of scouring funnel in front of the dam at Dengke hydropower station have been studied through the model test. The variations of transverse and lengthways gradient in different operation situations are summarized. Compared with similar prototype observations and other model tests,the test results are considered to be reasonable and the station can be operated safely. According to the result,the operational way of reducing the effective storage capacity loss of the reservoir has been put forward. |
