Rio Jurua: Born in serro the favors to 453 meters high, is one of the most important afliuentes the Amazon, to be quite voluminous and the most winding of the region. It has 3283 km in length and the width at the mouth in fente Consciousness Island, near Tamaniquá village, ranging from 350-400m. Bathes the cities of Carauari, Jurua, Eirunepé, Foreign Ministry, Ipixuna and Canamari. From its mouth to the river Tarauacá the average width is 140 meters, falling to 100-120 meters in spurts and 80-120 meters in the corners. Your bed can be varied between 8-16 meters in water levels between ebb and flood respectively. Over 1,000 kilometers from its navigable course are in full . During the dry season navigation is limited to 136 miles from its mouth. Its numerous tributaries are navigable itntensamente for much of the year as the summer arise in some shoals that impede traffic.
Madeira River: With 3,240 km, is the most notable tributary of the Amazon, born of the junction of the Mamoré and Guaporé rivers, opposite the waterfall "Wood", formed by large rocks and islands, as well as debris brought by the floods.

In the dry season, the river waters that flow into the Amazon, forming beaches along its banks. In this period, in your bed can be sighted the large amount of stones that help form the periodic rapids .
Coincidentally or not with the rainy season , while the river fills with rainwater in the opposite direction to the delta, it is invaded by the waters of the Amazon and rises about 17m, flooding all the waterfalls in your bed to form a water mirror that both invades forests as beaches and covers the entire Amazon plain. At that time, the Madeira river is no longer a simple tributary of the Amazon River and becomes a dependent navigation channel of the "tide" of this confluence. This vast backwater is responsible for the transfer of solid material deposited with the roots of vegetation come to form the great dunes.
Purus River: With equal muddy waters of the Solimões and varying color according to the time of the flood or ebb, the river is born with the name of Pucani at an altitude of 500 m, in Contamana saw that separates it from the Ucayalli river basin.

It runs through a continuous forest at the bottom of the great depression, lying between the Madeira River, which skirts the edge of the Brazilian sandstone plateau, and the Ucayali River, which hugs the base of the Andes. The river forms a small part of the international boundary between Brazil and Peru before it crosses over completely into Peru.
亞馬遜河，長達6,800公里（以祕魯南端爲源頭），是世界第二長河，位於南美洲，是世界流量、流域最大的、支流最多的、及最長的河流。亞馬遜河流量達每秒219,000立方米，流量比其他三條大河尼羅河、長江、密西西比河的總和還要大幾倍，大約相當於7條長江的流量，占世界河流流量的20%；流域面積達6,915,000平方公里，占南美州面積的40%；支流數超過1萬5千條。亞馬遜河從北緯5度伸展到南緯20度，源頭在安第斯山高原中，離太平洋隻有很短的距離，經過祕魯和巴西在赤道附近進入大西洋。
