The Amazon River of South America is the largest river in the world by volumetric discharge, with a total river flow greater than the next ten largest rivers combined. The Amazon, which has the largest drainage basin in the world, accounts for approximately one-fifth of the world's total river flow. In its upper stretches the Amazon river is called Apurímac (in Peru) and Solimões (in Brazil). During the wet season, parts of the Amazon exceed 190 kilometres (120 mi) in width.
The Juruá River is a southern affluent river of the Amazon River west of the Purus River, sharing with this the bottom of the immense inland Amazon depression, and having all the characteristics of the Purus as regards curvature, sluggishness and general features of the low, half-flooded forest country it traverses. It rises among the Ucayali highlands, and is navigable and unobstructed for a distance of 1133 miles (1823 km) above its junction with the Amazon.
The Javary River or Yavarí River is a 1,184 km tributary of the Amazon that forms the boundary between Brazil and Peru. It is supposed to be navigable by canoe for 900 miles above its mouth to its sources among the Ucayali highlands, but only 260 were found suitable for steam navigation. The Brazilian Boundary Commission ascended it in 1866 to the junction of the Shino with its Jaquirana branch.
The Marañón River rises about 160 km to the northeast of Lima, Peru, flows through a deeply-eroded Andean valley in a northwesterly direction, along the eastern base of the Cordillera of the Andes, as far as 5 degrees 36' southern latitude; then it makes a great bend to the northeast, and cuts through the inland Andes, until at the Pongo de Manseriche it flows through the plains. After its confluence with Río Ucayali, the Marañón is given the name of the Amazon River.
The Napo is a tributary to the Amazon River that rises in Ecuador on the flanks of the volcanoes of Antisana, Sincholagua and Cotopaxi. Before it reaches the plains it receives a great number of small streams from impenetrable, saturated and much broken mountainous districts, where the dense and varied vegetation seems to fight for every piece of ground. This river is one of Ecuador's Physical Features.
The Nanay River is tributary river to the Amazon River, west of the Napo in Peru. The Nanay is one of the three rivers that surround the jungle city of Iquitos, making it an island. Other nearby settlements on the river include the villages of Santo Tomás, Padre Cocha, and Santa Clara. During periods when the river is low, the many beaches along the Nanay are popular destinations.
The Purus is a tributary of the Amazon River in South America. Its drainage basin is 63,166 km (24,389 sq mi), and the mean discharge is 8,400 m³/s. It enters the Amazon River west of the Madeira River, which it parallels as far south as the falls of the latter stream. 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 which hugs the base of the Andes.
The Tigre River is a Peruvian tributary of the Amazon River west of the Nanay, and is navigable for 125 miles from its confluence with the Amazon. It forms from the confluence of the Ecuadorian rivers Cunambo and Pintoyacu at the Peruvian border. Like the Nanay, it flows entirely on the plains. Its mouth is 42 miles west of the junction of the Ucayali with the Amazon.
The Ucayali River (Río Ucayali) arises about 110 km (70 miles) north of Lake Titicaca, in the Arequipa region of South America. The Amazon River takes its name close to Nauta city (100 Km away from Iquitos), in the confluence among Ucayali and Marañón rivers.
The Madre de Dios River, homonymous to the Peruvian region it runs through, then becomes the Beni River in Bolivia and then turns northward into Brazil, where it is called the Madeira River. The Madeira is a tributary to the Amazon River. The Madre de Dios is an important waterway for the department of Madre de Dios, particularly Puerto Maldonado, the largest town in the area, and the capital of the department. Mango farming and Gold mining are among the many industries on its beaches.
Ibigawa is a town located in Ibi District, Gifu Prefecture, Japan. On January 31, 2005 the former villages of Fujihashi, Kasuga, Kuze, Sakauchi, and Tanigumi merged with Ibigawa, resulting in about a 4-fold increase in the town's population and a nearly 20-fold increase in area. As of this merger, the town has an estimated population of 74,400 (up from 18,625) and a density of 85 persons per km². The total area is 876.65 km² (up from 46.32).
Dikaios is a title given to holy men and women of the Old Testament in Eastern Christianity. The Greek word means righteous or just, and distinguishes the bearer from the Christian era saints. The prominent dikaioi are celebrated with their own feast days in the liturgical year. The Maccabees are commemorated as if they were Christian martyrs, and the Coptic Orthodox Church celebrates Pontius Pilate as one of the Righteous.
