Combined with Ertan Hydropower Station, Xiaowan Hydropower Station, Hongjiadu Hydropower Station and Tianshengqiao Hydropower Station I, a 3D numerical simulation is made on the hydraulic characteristics of intake for hydropower station with k-ε turbulent model; from which the head loss, velocity distribution, flow pattern, etc. are summarized. The numerical results are validated by the physical model experiment concerned.
