In this study, the flow pattern and sediment transport amount in a meandering river reach located in the downstream of the Minab dam (Hormozgan province, Iran) were simulated using CCHE2D model. First, the topographic maps with appropriate scale of the study area were obtained by accurate surveying, then the model geometry and the numerical mesh network with different size were created. Second, the required parameters for running CCHE2D model were collected through field works. Finally, the model outputs, including flow depth and velocity and changes in suspended load and bed load sediment were obtained for the considered river reach. In the end, the two statistical criteria, including RMSE and MAPE were used to compare the parameters obtained from the numerical simulation model with the corresponding observed values. The RMSE of velocity, depth and energy slope were calculated equal to 0.075, 0.116 and 0.0008, respectively. The corresponding values of MAPE were obtained as 2.7, 6.2 and 4.4 percent, respectively. Comparison of the results confirmed the high accuracy and low error of the model in simulating the flow and sediment parameters.
