Amazon Basin 40b Giwa Regional Assessment
The Amazon Basin is the largest basin on the planet and also one of the
least understood. Its drainage area covers more than one third of the
South American continent, and its discharge contributes almost one
fifth of the total discharge of all rivers of the world. The headwaters of
the Amazon River are located about 100 km from the Pacific Ocean and
it runs more than 6 000 km before draining into the Atlantic Ocean. In
addition, the Amazon has 15 tributaries, including the Tocantins River,
that measure more than 1 000 km in length.
