| Abstract | ||
| Shatt Al-Arab river suffer from high values of Total Dissolved Solid (TDS), these come from two sources the first is from Euphrates river and the second is from Arabian Gulf. Therefore, In this paper one dimension and unsteady case was applied to study hydrodynamic and TDS simulation of the river water by using HEC-RAS in Shatt Al-Arab river and associated rivers was done. HEC-RAS model is produced by US Army for analyzing river system. This model could simulate steady and unsteady open channel flow. The data of discharge, stage and TDS was taken daily for the year of 2014 at different sections along Shatt Al-Arab river and Tigris-Euphrates confluence. Some of these gauges was taken as boundary conditions and the others was taken for verification of the model. Calibration and verification of the Model using these data were done. Model results were compared with the observed data in these real rivers. The result show that a very good agreement between observed and simulated data with minimum correlation (R) was equal to 0.825. | ||
