ENVIRONMENTAL POLLUTION STUDY OF TIGRIS RIVER WITHIN BAGHDAD CITY USING REMOTE SENSING TECHNIQUES

Abstract The study was conducted for the recruitment of remote sensing technology to detect pollution in water of Tigris River within Baghdad city. Three satellites data was used: Landsat7 ETM+ U.S. satellite, with ground resolution of 30m, Spot5 French satellite, with ground resolutionof 2.5m,and Quick bird U.S satellite, with ground resolution of 0.6m,in addition to field survey which included the measurements of reflectance by photometer for the selected sites, A measurement of 36 points distributed along Tigris River starting from Kadhimiya town to the confluence point of Diyala River with Tigris River ,and stabilize the measurement points by means of G.P.S for the purpose of identifying the location of these points precisely on satellite images. Used program ERDAS 8.4 for image processing and classification of satellite images. The results showed the possibility of water separation in the river into three categories ,a natural water class ,polluted water with sewage and industrial pollutants class ,and shallow water class ,it has been shown that the increase in ground resolution will increase the possibility of water separation within the river to secondary classes .
