Brazil – April 25th, 2013

Some populated areas can be seen near the banks of rivers running through the Amazon Rainforest in the Brazilian states of Acre (below) and Amazonas (above). Near the left edge in the upper left quadrant is the municipality of Cruzeiro do Sul, on the banks of the Juruá River.

The Juruá is a southern affluent river of the Amazon River west of the Purus River, sharing with this the bottom of the immense inland Amazon depression, and having all the characteristics of the Purus as regards curvature, sluggishness and general features of the low, half-flooded forest country it traverses. It rises among the Ucayali highlands, and is navigable and unobstructed for a distance of 1133 miles (1823 km) above its junction with the Amazon. It has a total length of approximately 1500 miles (2414 km), and is one of the longest tributaries of the Amazon.

In this radar (ASAR) image we can see the winding, ribbon-like path of the Purus River (above) and the Acre River (below) through the Amazon in Brazil.

As you may have guessed from the great number of curves in the image, the Purus is one of the most crooked rivers in the world: its length in a straight line is less than half that by its curves.

It runs through a continuous forest at the bottom of the great depression. It is navigable for a period of about five months of the year, when the Purus valley is inundated; for the remaining seven months, only canoes can ascend it.

The Purus River has a very uniform width for 1000 miles (1600 km) up, and for 800 miles (1300 km) its depth is never less than 45 feet (15 m). Its drainage basin is 63,166 km², and the mean discharge is 8,400 m³/s.

The main tributary of the Purus is the Acre River (sometimes called Aquiry, or locally, Rio Acre) is a 650 kilometre (400 mi) long river in central South America.

The river rises in Peru, and runs eastwards, forming part of the border between Bolivia and Brazil. It runs through the Brazilian states of Acre and Amazonas before eventually running into the Purus River.
