At its mouth, the Orinoco River 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 River can swell to a breadth of 22 kilometres (14 mi) and a depth of 100 metres (330 ft).
The Orinoco Basin is the part of South America drained by the Orinoco river and its tributaries. The Orinoco watershed covers an area of about 990000 km 2 , making it the third largest in South America, covering most of Venezuela and eastern part of Colombia .
The delta is fan-shaped, formed by the Orinoco River as it splits into numerous distributaries, called caños, which meander through the delta on their way to the sea.The main distributary is called the Rio Grande, which empties south-southeast through the southern portion of the delta, and the second major distributary is Caño Manamo, which runs northward along the western edge of the delta.
The Guaviare is a tributary of the Orinoco in Colombia. It flows together with the upper Orinoco (until here also called Río Parágua), which it clearly surpasses in length (altogether about 1,760 km) and water flow. Thus, the Guaviare is hydrologically the main stream of the Orinoco system. [1]
The Caño Manamo is a distributary of the Orinoco River. It branches northwards from the main channel of the Orinoco to delimit the western edge of the Orinoco Delta, ultimately emptying into the Gulf of Paria. Tucupita, the capital of Delta Amacuro state, is located on the east bank (right) of the Caño Manamo. Manamo is a Warao word meaning ...
To the east the Orinoco wetlands and Orinoco Delta swamp forests occupy the Orinoco Delta. [2] The Llanos' main river is the Orinoco, which runs from west to east through the ecoregion and forms part of the border between Colombia and Venezuela. The Orinoco is the major river system of Venezuela. [3]
The proximity of the Orinoco Delta to the Gulf suggests that these waters are strongly influenced by fluvial discharges from the Amazon and Orinoco River systems, with the intensity of these discharges varying with the seasons (van Andel and Postma, 1954; Gade, 1961).
