| Abstract: | The low head and low Fr number of consumers have been a key issue in flood discharge and energy dissipation of middle and small hydraulic engineerings.Through hydraulic model test methods,the energy dissipation in Anning Hydropower Station's spillway were studied.The results of the study show that the arrangement with two rows of the stilling piers and a tail threshold at the end of the apron in the stilling basin with inflection could solve the problems of the stilling basin's energy dissipation and flow convergence of the spillway,increase the energy dissipation rate and improve the flow state in downstream river channel. |

| Keywords: | flood discharge and energy dissipation model test stilling basin with inflection energy dissipation rate |
