【 摘 要 】

Abstract The main aim of this study was to investigate the flow over an ogee spillway experimentally and simulating by both ANFIS and numerical model. An experimental study was conducted in order to obtain discharges and flow depths over an ogee spillway. Discharges and flow depths of flow in physical model were measured for 16 different total heads. A computational fluid dynamics program, which uses the Reynolds averaged Navier–Stokes equations to solve fluid problems, was used to simulate the flow over ogee spillway. As artificial intelligence methods have also been used with increasing the computer technology in all engineering problems, it was also used in this study in estimating the flow over the spillway. Finally, the flow parameters observed by physical study, numerical simulation and ANFIS model were compared with each other. Nondimensional discharge and flow depth curves are used to compare the results. Numerical and ANFIS models provide a cost-efficient simulating flow over spillways. The results show that there is reasonably good agreement between the physical, numerical and ANFIS models. Numerical solution methods and ANFIS models are also useful tools to design and analyze flow over an ogee spillway.
