3. Yangtze River (Asia) – 3,964 miles (6,380 km)
The Yangtze or Yangzi is the longest river in Asia, the third-longest in the world and the longest in the world to flow entirely within one country. Its source is in the northern part of the Tibetan Plateau and it flows in a generally eastern direction to the East China Sea. It is the sixth-largest river by discharge volume in the world. Its drainage basin comprises one-fifth of the land area of China, and is home to nearly one-third of the country’s population.
2. Amazon River (South America) – 3,977 miles (6,400 km)
At an average discharge of about 209,000 cubic metres per second, approximately 6,591 cubic kilometres per annum, greater than the next seven largest independent rivers combined—the Amazon represents 20% of the global riverine discharge to the ocean. The Amazon enters Brazil with only one-fifth of the flow it finally discharges into the Atlantic Ocean, yet already has a greater flow at this point than the discharge of any other river.
1. Nile River (Africa) – 4,132 miles (6,650 km)
The Nile is a major north-flowing river in northeastern Africa, and is the longest river in Africa and the longest river in the world. Its drainage basin covers eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan.
