Multi-level intake as an inlet of diversions has the advantage of selective withdrawal. To further understand the hydraulic characteristics of this inlet hydraulic structure, experimental model test and numerical simulation were carried out. The results of this study show that the water flow in the diversion channel is stable, and the flow pattern in the lock chamber section is disordered. In addition, the pressure near the entrance of the tunnel is linear, and the water head loss of the upper layer is the largest. Further, the formation of potential vortex flow can be prevented by controlling and scheduling. The results presented in the current work provide new insights into the hydraulics of flow in stratified intake structure and can be used in the design and operation of similar hydraulic projects.
