A single hydraulic model test of the scouring sluice of the Xunyang Hydropower Station on the Hanjiang River in Shaanxi Province identified the hydraulic characteristics of the scouring sluice under three different energy dissipaters.Stilling basin,apron and bedrock were studied under the condition of large discharge,middle-low water head,large unit discharge and relative submergence degree of large variable head.In particular,the discharge capacity design and calculation with a high submergence degree is analyzed,and the election of energy dissipaters in the lower reaches in the operation mode of flood discharge and sediment ejection operational mode with a relative submergence degree(hs/H0) of large variable head is analyzed.During flood discharge,the water level is high and the value hs/H0 is large,the energy dissipater of bedrock is better,and the aggregate discharge coefficient m′ ranges from 0.298 to 0.329.Also,the variable head of the submergence degree hs/H0 is large,and the energy dissipater of the stilling basin is more appropriate.
