The Meeting of the Waters

The 'Econtro das Aguas', better known as Meeting of Waters is the confluence between the pale sandy-colored and the dark (blackwater) Rio Negro and (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 much mixing. 

Why do these two rivers not collide? 

These two rivers flow together with this separation in tact for around 6km. The reason for this is having different water properties in the rivers. The Rio Negro river is relatively clear, despite having the darkish look. It is usually around 82.4 degrees Fahrenheit in temperature and flows slowly at around 1.24 miles per hour.

On the other hand the Amazon river has a different substane. Its water is virtually opaque because of all the sediment that it collected as a result of streams picking bits up as it streams down from the Andes area. The river is also much cooler than the Rio Negro, at 71.6 degrees Fahrenheit. The speed of the flow of this river is much faster as the water travels at around 3.7 miles per hour. Besides this there is also a difference in pH levels between the rivers.

During our 'Wonders of the Amazon tour' and our river cruises we show our guests this amazing beauty of nature.
