Abstract

The Rio Negro, a tributary of the Amazon River, is the largest “blackwater” river in the world. The concentrations of dissolved solids and suspended sediments are extremely low in the Rio Negro. Both loads amount to a considerable loss from the river basin because of the discharge, which is in the order of 20,000–40,000 m3/s, depending on the season.
