چکیده:

The modeling approach of concentration variations in rivers, basins is an important goal for predicting the interactions between main processes of hydrodynamic flow. Computational Fluid Dynamics (CFD) is modeling used for monitoring the behavior of flow components. In this study the simulation of flow hydrodynamic and concentration changes together with the sediment transport are considered. MIKE11 was selected for the modeling application in the case study. The basis of finite volume method with one dimensional procedure in the software is compatible with circumstances of the case study territory. The main equation is the shallow water equations in which the scale of features in the horizontal is much greater than the vertical direction. The shallow water equations are applied for more efficient numerical solution of flow in this environment. Furthermore equations describing the transport and fate of constituents in the water such as contaminants with sediment can be coupled to the hydrodynamic equations. The necessary data for simulation depends on time- series data such as wind direction, wind velocity, initial concentration values and flow components including temperature and salinity. Primarily, analyzing the hydrodynamic and concentration variation is processed. Then calibration has done during the optimization. Finally, the outcome and the observed data compared with the appropriate simulation. The more compatible results made to the best approximation of modeling for prediction of concentration
