Open channel junction flow is of interest in environmental and hydraulic engineering. It occurs in many hydraulic structures such as wastewater treatment facilities, irrigation ditch, fish passage conveyance structures, and natural river channels. This paper provides the details of application of numerical solution (Finite Volume) by FLUENT-3D software in simulation of 90° open channel junction flows. A three-dimensional turbulent model is developed to investigate the flow characteristics (velocity profiles) in open channel junction with different discharge ratios. Were comparisons of Weber made between numerical results and measured experimental velocities. Good agreement is obtained between the model simulation and experimental measurements. Statistical analysis of results obtained was, also, applied by using chi-square test (goodness-of-fit test) to ensure the previous conclusion.The correlation coefficient for all tests was not less than (0.952) .
