The Amazon River in South America is the largest river by discharge of water in the world, and the longest in length. It moves a huge volume of sediment each year and is of interest to researchers and resource extraction companies. 

At an average discharge of about 209,000 cubic meters per second, approximately 6,591 cubic kilometers per annum, the Amazon represents 20% of the global riverine discharge to the ocean. The Amazon basin is the largest drainage basin in the world, with an area of approximately 7,050,000 square kilometers (2,720,000 sq. mi), and accounts for roughly one-fifth of the world’s total river flow. The portion of the river’s drainage basin in Brazil alone is larger than any other river’s basin (Wikipedia).
