Amazon River (South America)
The Amazon River in South America is the largest river in the world by water discharge and total length. Each year it transports an immense volume of sediment, making it a subject of significant interest to researchers and resource extraction industries alike.
With an average discharge of approximately 209,000 cubic meters per second (roughly 6,591 cubic kilometers per annum), the Amazon accounts for around 20% of all global riverine discharge to the ocean. Its drainage basin is the largest in the world, covering approximately 7,050,000 square kilometers (2,720,000 sq. mi), equivalent to roughly one-fifth of the world’s total river flow. Notably, the portion of the drainage basin lying within Brazil alone exceeds the total basin area of any other river on Earth (Wikipedia).
The model grid used in this study comprises 78,077 cells, with an average orthogonal deviation of 2.92°. The grid extends from Yanchamayo, Peru, to the river’s mouth at the Atlantic Ocean. It was constructed in multiple stages and subsequently merged into a single, unified grid using Grid+ 1.1.
