%X To select an optimum shape of the diversion tunnel outlet for Sanhekou hydropower project, hydraulic model test was conducted to research the influence of outlet shape on the downstream riverbed scouring (range and depth) and bank slope. The test was designed in the presence of diffusion and stilling basin respectively under five working conditions. According to the test results and engineering practice, suggestions to optimize the outlet shape were put forward and further tested. Finally the optimum scheme was determined.
