Risk of contaminants modelling errors in Middle East waters

A developed numerical technique was employed for coupling the fully hydrodynamic motion of flow and sediment transport. A new spatial discretion was considered in numerical solution for polluted water governing equations. Risk of pollutions concentration in worldʹs richest area "Persian gulf catchment" was investigated through a comprehensive analysis of the hydrodynamic flow- Eco-lab concentration techniques. Appropriate dataʹs and real physical problem was undertaken in modeling. The quality control and risk analysis of flowing pollutants movement into the Gulf via a river-reservoir system was made. Computational prediction errors indicated, the concentration was controlled from pollution mode and the risk was substantially decreased. Predicting errors in flow-sediment parameters was found satisfactory compared to observed targets. Finite volume, Computational Fluid Dynamic (CFD) techniques adopted here found adequate, consistent, stable and convergent as expected with least errors.
