Where is the river Orinoco and where is its source and length
The Orinoco is one of the longest rivers in South America at 2,140 kilometres (1,330 mi). Its drainage basin, sometimes called the Orinoquia, covers 880,000 square kilometres (340,000 sq mi), with 76.3 percent of it in Venezuela and the remainder in Colombia.he Orinoco delta, and tributaries in the eastern llanos such as the Apure and Meta, were explored in the 16th century by German expeditions under Ambrosius Ehinger and his successors. In 1531 Diego de Ordaz, starting at the principal outlet in the delta, the Boca de Navios, sailed up the river to the Meta. Description. Venezuela in South America is home to the Orinoco River. The river starts high in the mountains of central Venezuela, and by the time it reaches the bottom of the valley it has become a torrential flow of water.It travels 2,100km from its source before it reaches the sea.Tropical forests make travelling on land difficult, so the river is used for transport.he river starts high in the mountains of central Venezuela, and by the time it reaches the bottom of the valley it has become a torrential flow of water. It travels 2,100km from its source before it reaches the sea. Tropical forests make travelling on land difficult, so the river is used for transport. At its mouth, the Orinoco forms a wide delta that branches off into hundreds of rivers and waterways that flow through 41,000 km 2 (16,000 sq mi) of swampy forests. In the rainy season, the Orinoco can swell to a breadth of 22 kilometres (14 mi) and a depth of 100 metres (330 ft).he Orinoco delta, and tributaries in the eastern llanos such as the Apure and Meta, were explored in the 16th century by German expeditions under Ambrosius Ehinger and his successors.

Over 200 rivers are tributaries to the mighty Orinoco which extends 1290 mi (2150 km) from source to delta. During the rainy season, the river reaches a width of 13 mi (22 km) at San Rafael de Barrancas and a depth of 330 ft (100 m).see map) The most notable fall in this area, at 56 ft (17 m) is Salto Libertador. Navigation, where possible on this part of the river, is by shallow dugout, or canoe. 60 miles (100 km) from the source, the first tributary, the Ugueto, joins the Orinoco. By Bonnie Hamre. The Orinoco river system is one of the largest in South America, originating along the southern borders of Venezuela and Brazil, in the state of Amazonas.see map) The most notable fall in this area, at 56 ft (17 m) is Salto Libertador.

The mouth of the Orinoco at the Atlantic Ocean was documented by Columbus on 1 August 1498, during his third voyage. Its source at the Cerro Delgado-Chalbaud, in the Parima range, was not explored by non-indigenous peoples until 1951, 453 years later.he Orinoco delta, and tributaries in the eastern llanos such as the Apure and Meta, were explored in the 16th century by German expeditions under Ambrosius Ehinger and his successors. In 1531 Diego de Ordaz, starting at the principal outlet in the delta, the Boca de Navios, sailed up the river to the Meta.

In 1498, Columbus reached one of the estuary branches of the Orinoco, and it is believed that members of the Spanish expedition of A. de Ojeda and A. Vespucci saw one of the Orinoco’s branches. In 1531 the Spanish conquistador Diego de Ordaz first navigated the Orinoco to its confluence with the Meta River.n 1498, Columbus reached one of the estuary branches of the Orinoco, and it is believed that members of the Spanish expedition of A. de Ojeda and A.

The Amazon basin is 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.long with the Orinoco, the Amazon is one of the main habitats of the boto, also known as the Amazon river dolphin (Inia geoffrensis). It is the largest species of river dolphin, and it can grow to lengths of up to 2.6 metres (8 ft 6 in).
It is one of the longest rivers in South America at 2,140 kilometres. It begins from the Parima mountains in the Venezuela.
