The Meeting of Waters (Template:Lang-pt) is the confluence between the dark (blackwater) Rio Negro and the pale sandy-colored (whitewater) Amazon River, referred to as the Solimões River in Brazil upriver of this confluence. For 6 km (3.7 mi) the two rivers' waters run side by side without mixing. It is one of the main tourist attractions of Manaus, Brazil.[1]
This phenomenon is due to the differences in temperature, speed and water density of the two rivers. The Rio Negro flows at near 2 km/h (1.2 mph) at a temperature of 28 °C (82 °F), while the Rio Solimões flows between 4 and 6 km/h (2.5–3.7 mph) at a temperature of 22 °C (72 °F).[1]
The phenomenon is common in the Amazon and also occurs on a smaller scale in the locations of Santarém (Brazil) and Iquitos (Peru).
