One of the main attractions for travelers to Manaus is the visit to the Meeting of the Waters. The phenomenon is considered a Brazilian tourist spot, and many travel agencies offer boat tours of the region, carried out in Janauari Ecological Park.
These tours are more frequent in the period of full river (January to July), and in addition it becomes more clear the beauty of the natural spectacle and also you can still see many animals like birds, monkeys, sloths and more. A tour really unforgettable. But you know why this happens? Why the waters do not mix?
It's amazing, but for more than 5 km the clear and muddy waters of the Solimões river run side by side with the black water of the Negro river, without mixing. The "Rio Negro" as its name suggests, is a river of very dark waters. Its black tea staining is due to the large amount of organic acids from decaying vegetation. It features a high degree of acidity, pH 3.8 to 4.9, has an average temperature of 28 ° C and flows slowly to about 2 km per hour.
For other hand the Solimões River has a very similar muddy color with latte. All this because of the large number of sediment that the water carries to flow beneath the Andes. It is cooler than the Rio Negro, having 22° C. In addition, flows much faster, running about 6 km per hour.
The Meeting of the Waters is the meeting of the Rio Negro and the Rio Solimões, that initially do not mix. Once they join, were given the name of the Amazon River, a major economical means and transport for the inhabitants of the city of Manaus.
The composition difference of the acidity rate, flow temperature and the density is what prevents mixing of the two when they meet. The color contrast is very striking, and this phenomenon can be seen even from space.
Sometimes the water encounters obstacles that form strong swirls shaking the two rivers, making very beautiful shapes.
