I was inspired by a comment made by Abbas, “He has set free the two seas meeting together. There is a barrier between them. They do not transgress. ” (Quran, 55:19-20) on the Water: The Two Colors River post, I found that it’s not only in Laos and Thailand that have the two colors river, but in other parts of the world as well, this one is very profound, it is the meeting of the waters Rio Negro and the Rio Solimoes in Manaus, Brazil, photographs by Global Nomad1 at Flickr.

According to Global Nomad1, the dark water from the Rio Negro gets its color from the humic acids of decomposing forest litter. The muddy waters of the Rio Solimoes originate in the Peruvian Andes, where erosion contributes huge quantities of sediment. The two rivers meet near the city of Manaus in the Brazilian Amazon.
