Combined with the actual project of a hydropower station, the turbid water test is used to verify the sedimentation of the power branch tunnel under the sand discharge conditions. The results show that under the sand discharge conditions, there are different degrees of siltation outside the recirculation zone of the power branch tunnels in the bifurcation section, and the siltation form is a delta siltation form. The sedimentation volume of the power branch tunnel is related to the sediment discharge flow in the sand discharge pipe. The greater the sediment tunnel flow, the greater the sedimentation in the cecum section of the power branch tunnel when the siltation balances.
