Abstract
The present study aims to utilize chemical analysis, remote sensing and geographic information system (GIS) for mapping surface conditions of the Burullus Lake, Egypt as a proxy to water pollution. Spatial distribution of suspended matter, nitrogen, phosphorous, chlorophyll (a, b and c), carotenoid, dissolved oxygen, pH, water temperature, salinity, depth, lead, copper and cadmium (in water), clay, sand, silt, lead, copper and cadmium (in sediment) and sediment organic carbon has been applied. A Landsat image from the Enhanced Thematic Mapper plus (ETM+) sensor acquired in June 2006 was processed on the basis of band by band as well as band rationing. Cartographic maps were generated depending on the correlation between the measured parameters and the radiance values of the ETM+ image. Some parameters not correlated with the satellite image data have been processed through spatial analysis and interpolation technique using GIS. Other parameters like pH, chlorophyll (c) and (b), carotenoid, sand, silt and (lead, copper and cadmium in sediment) have been analyzed and represented graphically. Results showed that the eastern and southern sections of the lake, which receive drainage wastewater, are more polluted than the northern and the western sections of the lake. The study confirms that remote sensing coupled with GIS could afford an integrated scheme for mapping water quality.
