    White water of the Solimões and black water of the Rio Negro converge to form the Amazon River. The Amazon watershed covers about 5,846,100 square kilometres (2,257,200 sq mi). [12] The Amazon River accounts for 15–16% of the total water discharged by rivers into the oceans of the world. [2] Rivers may be blackwater, whitewater or clearwater.
