Formation of the vortices in a horizontal water intake structure composed of a reservoir-pipe system is investigated using 3D numerical modeling. The geometrical and hydraulic conditions of the system such as pipe diameters, the distance between the side walls of the intake and the flow discharge is altered and the critical submergence depth required for the formation of the vortex for each test is determined. Although it is possible to capture an air-entraining vortex in the numerical model, there is a deviation in the critical submergence depth compared with the experimental results. Scale effect on the formation of air-entraining vortex is also investigated comparing model and prototype simulations.
