|Manaus, the capital of the state of Amazonas, is located on the north bank of the River Negro at its confluence with the Solimoes River, which extends eastward as the Amazon River. The population of Manaus grew by more that 65 per cent between 1993 and 2003 to its current population of over 1.5 million.|
These two Landsat images document the conversion of forest areas due to logging and urbanization between 1987 and 2001. The city of Manaus can be seen in grey toward the lower right corner of the images. In addition to the urban expansion evident in the area surrounding the city, increased logging and road construction can be seen in the 2001 image. The rectangular area of mature forest on the northern border of the city is the Adolpho Ducke Forest Reserve.
About 15 kilometers from Manaus, Rio Negro (Black River) meets Rio Solimoes to create an amazing confluence of the brownish white water from the Saliomes joining the black water (caused by the very high acidity from tannin) from the Rio Negro. The Rio Solimoes appears blue in this image, the Rio Negro black. The black waters of the Rio Negro are not completely absorbed until many miles after the two rivers merge. View detailed information
