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. ©2017 AL-Muthanna University. All rights reserved.

阿拉伯沙河水动力HEC-RAS模型的应用

阿拉伯河的总溶解固体(TDS)含量较高，其来源有两个:一是幼发拉底河，二是阿拉伯湾。为此，本文采用一维非定常情况，利用HEC-RAS对沙河及伴生河流进行了水动力和TDS模拟研究。HEC-RAS模型是美国陆军为分析河流水系而制作的。该模型可以模拟明渠的定常和非定常流动。2014年每天采集阿拉伯河和底格里斯河-幼发拉底河汇合处不同河段的流量、水位和TDS数据。其中一些量规作为边界条件，其他量规作为模型的验证。利用这些数据对模型进行了校正和验证。将模型结果与实际河流的观测数据进行了比较。结果表明，观测值与模拟值吻合较好，相关系数R为0.825。©2017 AL-Muthanna University。版权所有。收稿日期:11/10/2016
