In this paper, using a 3D numerical model, the flow pattern at lateral intake was simulated. A three-dimensional finite volume model with standard  was developed to solve turbulence equations. In order to simulate the main and diversion channels, only one block with varied domain arrays was used. The Reynolds-Averaged Navier-Stokes (RANS) equations are solved in a curvilinear non-orthogonal coordinate system with collocated grid. Pressure correction algorithm of SIMPLE and convection schemes of Power Law are applied to the model. In addition, for velocity-pressure coupling; the Rhie and Chow method were used. Experimental data obtained from laboratory study is utilized to verify the model computations. The flow pattern at lateral intake with one-block numerical method was modeled. The numerically modeled results show acceptable agreement with the measured data and demonstrate the capability of the developed numerical model.
