In this study, the unsteady pattern of the meander bend in the Gomati River flow is analyzed using CCHE2D. Different Manning's roughness factors and turbulent simulations were used to validate the CCHE2D model. For two different flow rates, simulation results were compared with data collected in the field. The results show that for both minimum and maximum discharges, smaller Manning's roughness factor are preferred to higher Manning's roughness factor . Similarly, the measured and reflected magnitudes are changed in hydraulic parameters such shear stress, velocity, flow depth, and Froude number. The results of the numerical model showed that the presence of centrifugal force and helical cells strongly impacts variation in flow structure in the river bend. In the cross sections of a meander bend, the gradient of the water surface latitude is altered by helical flow and the depth averaged velocities. The linear and direct relationship between velocity and shear stress is presented across the whole study reach, as indicated by the R-square and linear correlation coefficient (r) components. The results of the model show that the flow field within the river bend can be accurately simulated by the computational model.
