The Amazon River which is the longest river in the world with a length of 6992 Km (approx 4300 miles) is also the widest with an average width of 11 Km (6.8 mi) in the dry season and up to 190 km (120 mi) during the rains. The Amazon River is a huge river flowing mainly through Peru and Brazil and also draining the borders of Ecuador, Columbia, and Bolivia. Amazon sustains a tremendous amount of species as well as commercial transport activities and huge undisturbed forests.
The river has an average discharge of 209000 cubic meters/second which is the largest in the world and also it has a total basin area of 7050000 sq km. Having originated in the Andes Mountains, Peru in the western part of South America it flows east to the Atlantic Ocean. Though the Amazon River is closely followed by the Nile in terms of length, the maximum width attained by the Nile is only 7.5 Km, undisputedly making Amazon the widest river on the planet.

Headwaters of Amazon/Origin/History
Since the past century, it was believed that Amazon has its headwaters in southwest Peru. The Apurimac River, originating from the glacial ridge of Mismi at an elevation of about 5597 meters (18363 ft) was believed to be the main tributary of Amazon till 2014 when a study found it to be in the Cordillera Rumi Cruz at the headwaters of Mantaro River in Peru. Both Apurimac and Rumi rivers meet with other tributaries to form the main stem of the Amazon. The upper parts of the Amazon are called Solimoes River by the Brazilians before its confluence with one of the main tributaries, Rio Nigro which is also one of the world’s 10 largest rivers in terms of discharge.
The flow of the Amazon
The flow of the Amazon can be divided into the upper Amazon, lower Amazon and its mouth where it meets the Atlantic Ocean.
Before its confluence with Rio Nigro, the river is known as ‘Solimoes Das Aguas’ in Brazil. The river system and flood plains in Peru, Brazil, Ecuador, Venezuela and Columbia whose water drain into The Solimoes constitute the upper Amazon. The upper Amazon is supported by an extensive network of tributaries in Columbia, Ecuador and Peru ex- Putumayo, Morona, Pastaza, etc and also branches out into a number of small distributaries only to meet the main river downstream. Parts of the landscape surrounding the upper Amazon are mostly submerged underwater.
The lower Amazon begins at the confluence of Rio Nigro and Solimoes. The confluence is a huge tourist attraction as the waters of the two rivers can be distinctly identified for nearly 6 km. Rio Nigro has darkly colored water while the water of Solimoes is sandy colored making their confluence a most sought after tourist attraction in Brazil. The Northern bank of the river is marked with a number of steep hills with flat tops, while the southern bank of the river has a series of steep banks.
The mouth of the Amazon is located in eastern Brazil near the city of Belem, which is also an important port. The exact location of the mouth of Amazon cannot be ascertained because of the complex geography of the area. It has numerous small and big islands that are flooded twice daily due to tidal activities. The area abounds in clay and sedimentary deposits and numerous islands resulting due to sedimentation. The area also supports rich forests and huge ecology.
Myths Related with Amazon

- El Dorado
Brazilians believe that deep inside the Amazon forests, there is a hidden kingdom named El Dorado which still remains to be explored. This belief has formed the basis of many scientific and adventure explorations.
This is another superstitious belief of the natives of Amazon. They believed that the spirit of a farmer is constantly on the lookout for those who are lost in the forest. He personifies himself as someone who they trust and guides them deep into the jungle until they are completely lost. The ‘Chuyachaki’ then wait for them to die.
- Ayay Mama
The story surrounds two kids of a widowed father- an elderly girl and a young boy. Their father was forced to abandon the kids by their stepmother so that her heir would be confirmed. The father led them into the deep jungles where they were lost, but the forest goddess took pity on them and adopted them in form of birds, whose shrieks still today can be heard in the deep forests surrounding the Amazon.
Ancients believed that the daughter of a respected king mysteriously got pregnant and was therefore condemned and forced to leave the kingdom. Consequently, she gave birth to a girl child having the color of the moon. When the locals saw the magical color of the child, they brought back both the mother and child to the kingdom and celebrated their return. Unfortunately, the child only lived until her first birthday. Where the child, named Mani was buried a strange plant sprouted on the grave. The locals cut the stem and witnessed that the soft inner part has the same white color as Mani and was delicious to eat. To honor the child they named the plant Mandioca.
