The largest river on the planet, the Amazon, forms from the confluence of the Solimões (the upper Amazon River) and the Negro at the Brazilian city of Manaus in central Amazonas. At the river confluence, the muddy, tan-colored waters of the Solimões meet the “black” water of the Negro River. The unique mixing zone where the waters meet extends downstream through the rainforest for hundreds of kilometers, and is a famous attraction for tourists from all over the world. The tourism contributes to substantial growth in the city of Manaus. Twenty years ago the large park near the city center (center) lay on the eastern outskirts of Manaus.

Ciudad Guayana lies on the south bank of the Orinoco River, the second largest in South America, at its confluence with the Caroní River (lower left). Islands have developed in the Orinoco in a wide spot opposite the city (upper left). A low barrage (lower left) dams the Caroní as a water supply for the city. The Orinoco River is a muddy brown, carrying sediment produced by erosion of the Andes Mountains far to the southwest. By contrast, the Caroní is clear blue, as it drains the ancient landscapes of the Guyana Highlands, where erosion is much slower. As at the famous confluence of the muddy Amazon and clear Negro rivers in Amazonia, a mixing zone can be seen in the middle of this image. The clear Caroní water produces a less muddy zone for tens of kilometers downstream of the confluence (this part of the Orinoco flows almost due east, left to right).
