Hydrology
We are concerned with two major aspects of hydrology with respect to the biogeochemistry of the Amazon River: basin-wide hydrology and the dynamics of the major tributaries. Our modeling effort focuses primarily on the transport of sediment and nutrients to the mainstem. Thus far, our work has concentrated on modeling rainfall and flowaccumulation to the rivers as represented in digital datasets of the river network.
Basin Boundaries
Because we cannot obtain a good digital elevation model (DEM or DTM), we digitized a boundary, based primarily on DCW rivers, but sometimes using RADAM rivers from paper maps, and DCW contour lines. The area of the red polygon shown is 5964817 square kilometers. The smaller basin to the right is the Tocantins. (The Tocantins is a river that flows north from near Brasilia to near Belém. It is sometimes -- but not usually -- considered part of the Amazon Basin.)
