Multi-level intake of diversion project has the advantage of selective intake. To further understanding of the hydraulic characteristics of this intake, a numerical simulation was carried out by RNG k – ε turbulent model. The parameters of flow pattern and velocity distribution, water head loss, water source stratification are analyzed. Researches show that the local flow shape is complicated. The water head loss coefficient at inlet is in a range of 0.31 to 0.62. The effect of multi-level intake structure is fairly good. The results provide reference for the design and operation of similar engineering.
