São Francisco River, Brazil
A particularly wide segment of the São Francisco River in Brazil is visible in this image. The São Francisco River has a length of 3,160 kilometres. It is the fourth largest river system in South America and the longest river wholly within Brazil.
As we can tell from the light green and tan terrain near the river, it does not run through the luscious Amazon Rainforest but rather lies towards the drier east coast. The water appears light tan, partially from sediments and partially from sun glint.
Beginning in the state of Minas Gerais, the São Francisco River runs generally north behind the coastal range draining an area of over 630,000 square kilometers before turning east to form the border between the state of Bahia and the states of Pernambuco and Alagoas. It then enters the Atlantic Ocean between the states of Alagoas and Sergipe.
The area crossed by the river is vast, dry and sparsely populated, but several towns do lie along the river.
