Measuring The Water Pollution Of selected Sites In Al- Najaf Covenarate(TSS) And Using Remote Sensing Data

The current study was conducted in Najaf governorate within the Kufa district to measure the percentage of pollution (TSS) in the Euphrates River (Shatt Kufa) and the length of about 25 km. he purpose of this study is to determine the estimated concentration of total suspended solid in the Shat Kufa by Landsat 8 OLI. The data was distributed by the United States Geological Survey (USGS) and downloaded from Earth Explorer website (2018-12-15) using remote sensing data, the study samples were collected from (10)(2018 -12-22) starting from the north of Kufa - Zarka area to the south of Kufa bridge cement plant and a length of about 14.5 km. Most of the concentration of TSS spread across the northern and southern parts of the Shatt al-Kufa, as a result of cesspits, as well as the drainage of a number of waterways (the northern Kufa and Buhadi districts) directly to the Shat al-Kufa. The results of the analysis of correlation between reflectivity (r) for the degrees of remote sensing and TSS) in the laboratory of the Department of Environment / Faculty of Sciences / University of Kufa band (4) Highest correlation and accuracy reached: ((r=0.917,R²=0.840,RMSE=4.5225,MRE=1.1649) While the band (1) less coherent and accurate as it reached:( (r=0.562,R²=0.316,RMSE=5.4683 mg/l,MRE=1.5739%).
