How Much Water Does The River Amazon Contain ?

Answer Question

    Nobody knows, and nobody is even too sure how to calculate it.  

    In the dry season, where the Amazon river opens out to the sea, it's "about" 11 km (7 miles) wide.  It's believed over the year to disgorge to the ocean about 20% of the global amount of fresh water going into the sea, or 220,800 cubic metres (tonnes of water) per second.  It drains 40% of the South American continent, and formerly flowed into the Pacific (before the Andes mountains built up).  The length of the Amazon is disputed.  It's shorter than the world's longest river (the Nile system), but much wider.

    When the Amazon floods each year, it sinks the land (the Earth's crust) in the flood plain by about 3 inches (the land rebounds in the dry season).

    In the rainy season, some sources quote the average depth as 40m, average width 40km.  If the river were taken as 1600km long, that suggests a snapshot volume of 2.56 billion metric tonnes of water in the river, during a single moment in the rainy season, with more being added all the time.
