| Abstract | ||
| A study concerns the dispersion of pollutants in Diyala River using one-dimensional finite difference technique (implicit method) to solve the simplified dispersion equation. The model starts at Diyala barrage and extend to the confluence of the Tigris - Diyala Rivers, and for 203-km length. The simplified dispersion model results were verified by comparison with the analytical solution for different time increments. The calibration of the model was conducted on 31/11/1998 using measured data (discharge, velocity, cross sectional area, total dissolved solids (TDS), chloride (CL), and sulfate (SO4) concentrations at the same day and results indicated a good agreement between the computed and measured data. The verification of the model is accomplished on (13/12/98, 27/12/98, 10/1/99, 25/1/99) and the results indicates also the accuracy of the applied model to simulate the conservative salts (TDS, CL, So4) in the river. | ||
