Which does river discharge the most water in the world?
Which rivers carry the most water? By far, Brazil’s Amazon River carries more water to the sea than any other river in the world. The discharge at the mouth of the river is about seven million cubic feet (170,000 cubic meters) per second, which is about four times the flow of the Congo in Africa, the river ranked second in terms of discharge.

Victoria Falls is often called the largest waterfall in the world, although it is neither the highest nor the widest. It has a width of 1.7 kilometers (1 miles) and height of 108 meters (360 ft), roughly twice the height of North America’s Niagara Falls. In combined height and width Victoria Falls is rivaled only by South America’s Iguazu Falls.

Major watersheds (area sq km) - The World Factbook

How many watersheds are there in the world?
This report for the first time presents and analyzes a wide range of global data at the watershed level, assessing 154 watersheds around the world. The analysis focuses on watershed, as ecological units and on the risks of degradation from human activities, which may undermine their ability to provide ecological services and maintain intact the biodiversity found within them. The analysis is based on 15 global indicators that characterize watersheds according to their value, current condition, and vulnerability to potential degradation. These indicators, presented in more than 150 maps, give a unique global perspective on the largess transboundary watersheds, as well as many smaller basins and sub-basins.

What are drainage basins?
The list of drainage basins by area identifies basins (also known as "catchments" or, in North American usage, "watersheds"), sorted by area, which drain to oceans, mediterranean seas, rivers, lakes and other water bodies.
