This made the fields very fertile, but still no more fertile than the lands near the Amazon. The other thing it did was destroy everything near the water's edge.
All the farms and buildings near the water were swept away when the Nile flooded. The destructive potential of the flood was so great that small bands of hunters could not control it. People were forced to join together in larger groups to manage the waters of the Nile.
After the flood waters subsided, new farm buildings had to be set up and the boundaries of all the farms had to be marked again so farmers would know where their land ended and their neighbor's began.
Yet the societies that grew up around them could not be more different. The Amazon River also has a large number of tributaries, including the Rio Negro, which is one of the largest rivers in the world in terms of volume.

The Brazilian scientists' day expedition extended the Amazon's length by about miles kilometers , making it 65 miles kilometers longer than the Nile.
According to the team's results, which have not been published, the Amazon is 4, miles 6, kilometers long. The Nile stretches 4, miles 6, kilometers. The Amazon and the Nile have been at the center of a centuries-old rivalry over the "world's longest" title. Determining the length of a river is tricky because scientists have to pinpoint both where the river begins and ends, Andrew Johnston, a geographer at the Smithsonian's National Air and Space Museum in Washington, D.
Though Johnston was not a part of the research team, he is familiar with the Amazon mapping effort. He participated in related research in , which was funded in part by the National Geographic Society. The debate over river length is trivial, he said, but he hopes the announcement will focus international attention on the Brazilian government's efforts to build more than 60 large dams on the Amazon's major tributaries.
All rights reserved. Long Rivalry The Amazon and the Nile have been at the center of a centuries-old rivalry over the "world's longest" title. In the 20th century, consensus gave the title to the Nile. The river starts in the Andes of Peru, and flows through four other countries, including Bolivia , Venezuela, Colombia, and Ecuador, before ending the trail in Brazil, where it spills into the Atlantic Ocean.
This body of water also runs through the heart of the Amazon Rainforest, the largest tropical rainforest in the world. The Amazon River plays a central role in the cultures and traditions of the people who live near it.
It has only been since that the Amazon has been considered the longest river in the world. For years, the river actually came second to the Nile River, which runs from the mountains of Burundi to Egypt , where it spills into the Mediterranean Sea. The Nile runs for 4, miles throughout Africa.
Because rivers are constantly seeing changes with waterflow and seasons, it can be extremely difficult to get accurate surveys on length and distance. The issue that caused this miscalculation over the years was the way the rivers were being measured.
The Nile runs in a relatively straight line from start to the outlet, making it much easier to measure. The Amazon, on the other hand, only covers about 1, miles in a straight line distance, however, it spans out in a greater overall area coverage.
