Abstract

The stream of rivers and lakes are more susceptible to pollution than other water sources because they are in direct contact with various human activities, specifically agricultural and industrial ones. The main aim of this paper is to simulate the effect of two positions discharged sewage water to Euphrates River to determine the distance that river reach to self-purification. In this study the effect of two sites that discharge pollutants into the Euphrates River was investigated using the Streeter-Phelps equation: al-Hindiya and Twerij. Four scenarios were chosen for the drainage of the Euphrates River: 150, 170, 200, 315 m3/sec at the al-Hindiya-Euphrates junction and 150, 170, 200 m3/sec at the Twerij-Euphrates junction. In addition, four scenarios for the disposal of sewage waste which: 5, 6 , 8, 10 m3/sec for each discharge. The results demonstrated that the distance traveled to self-purification was 143 km at discharge150 m3/sec and al-Hindiya discharge is 5 m3/sec. While the distance was 65 km at discharge is 150 m3/sec and Tuwaireej discharge is 5 m3/sec. these distances decrease with the increase in the discharge of the river.
