Numerical Simulation of Flow and Sediment by CCHE2D (Case Study: Downstream Meander of the Minab Dam)

In This study using CCHE2D, to simulate flow and sediment transport pattern meandering river reachlocated in the downstream of the Minab dam (Hormozgan province, Iran). First, the geometry model and after that a numerical mesh systemwere calculated using the topographic surveysof the study area. Second, the required parameters for running CCHE2D were collected through field works. Finally, the model outputs including flow depth and velocity and changes in suspended load and bed sediment were obtained for the considered riverreach. In the end, the two statistical criteria RMSE and MAPE, the data obtained from numerical simulation model against observational data were compared. Model error parameters, RMSE of velocity, depth and energy slope, respectively, 0.075, 0.116 and 0.0008 and the index of MAPE respectively, 2.7, 6.2 and 4.4 percent. The results comparison indicated that the simulated values matched well with the field measurements.
