Important Rivers of the World – July 27th, 2011 – EOSnap Celebrates its 4000th Post!46.2N 49.4E
Eosnap celebrates its 4000th post with a look at recent images of the mouths of a few of the world’s most important rivers: the Volga, the Nile, the Rio de la Plata and the Amazon.
The main image shows the delta of the Volga River where it empties into the Caspian Sea. The Volga, which flows through central Russia, is the largest river in Europe in terms of length, discharge, and watershed. It rises in the Valdai Hills 225 meters (738 ft) above sea level north-west of Moscow.
The Nile is a major north-flowing river in North Africa, generally regarded as the longest river in the world. It is 6,650 km (4,130 miles) long and runs through eleven countries. The northern section of the river flows almost entirely through desert, from Sudan into Egypt. North of Cairo, the Nile splits into two branches (or distributaries) that feed the Mediterranean: the Rosetta Branch to the west and the Damietta to the east, forming the Nile Delta.
The Río de la Plata is the river and estuary formed by the confluence of the Uruguay River and the Paraná River on the border between Argentina and Uruguay. It is a funnel-shaped indentation on the southeastern coastline of South America, about 290 kilometres (180 mi) long. The Río de la Plata widens from about 2 kilometres (1.2 mi) at the inner part to about 220 kilometres (140 mi) at its mouth. The major ports and capital cities of Buenos Aires and Montevideo on its western and northern shores, respectively.
The Amazon River, also in South America, is the second longest river in the world and by far the largest by waterflow with an average discharge greater than the next seven largest rivers combined. The Amazon, also has the largest drainage basin in the world, about 7,050,000 square kilometres (2,720,000 sq mi), and accounts for approximately one-fifth of the world’s total river flow. The width of the Amazon varies between 1.6 and 10 kilometres (0.99 and 6.2 mi) at low stage, but expands during the wet season to 48 kilometres (30 mi) or more. The river enters the Atlantic Ocean in a broad estuary about 240 kilometres (150 mi) wide. The mouth of the main stem is 80 kilometres (50 mi).
