Orinoco
The Orinoco () is one of the longest rivers in South America at . Its drainage basin, sometimes known as the Orinoquia, covers , with 76.3 percent of it in Venezuela and the remainder in Colombia. It is the fourth largest river in the world by discharge volume of water. The Orinoco River and its tributaries are the major transportation system for eastern and interior Venezuela and the Llanos of Colombia. The environment and wildlife in the Orinoco's basin are extremely diverse. Etymology The river's name is derived from the Warao term for "a place to paddle", itself derived from the terms ''güiri'' (paddle) and ''noko'' (place) i.e. a navigable place. History The mouth of the Orinoco River at the Atlantic Ocean was documented by Christopher Columbus on 1 August 1498, during his third voyage. Its source at the Cerro Delgado–Chalbaud, in the Parima range, was not explored until 453 years later, in 1951. The source, near the Venezuelan–Brazilian border, at ab ...

Casiquiare River
The Casiquiare river () is a distributary of the upper Orinoco flowing southward into the Rio Negro, in Venezuela, South America. As such, it forms a unique natural canal between the Orinoco and Amazon river systems. It is the world's largest river of the kind that links two major river systems, a so-called bifurcation. The area forms a water divide, more dramatically at regional flood stage. Etymology The name ''Casiquiare'', first used in that form by Manuel Román, likely derives from the Ye'kuana language name of the river, ''Kashishiwadi''. Discovery In 1744 a Jesuit priest named Manuel Román, while ascending the Orinoco River in the region of La Esmeralda, met some Portuguese slave-traders from the settlements on the Rio Negro. The Portuguese insisted they were not in Spanish territory but on a tributary of the Amazon; they invited Román back with them to prove their claim. He accompanied them on their return, by way of the Casiquiare canal, and afterwards retraced h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orinoco Delta
The Orinoco Delta is a vast river delta of the Orinoco River, located in eastern Venezuela. Location The Orinoco Delta is one of the eight natural regions of Venezuela. It covers the whole of Delta Amacuro State and a few square kilometers of Monagas State and Sucre State, comprising all the mouths of the Orinoco. It is divided into two sections: the principal, at the northernmost part of the system, located between Caño Manamo and the left shore of Caño Araguao, where the majority of villages are established, including the state capital Tucupita; and the secondary, between the right shore of Caño Araguao and Río Grande. The Warao people live in the region. Hydrology 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 secon ...

Ciudad Guayana
Ciudad Guayana () (in English Guayana City) is a city in Bolívar State, Venezuela. It stretches 40 kilometers along the south bank of the Orinoco river, at the point where it is joined by its main tributary, the Caroní river. The Caroni crosses the city south-north and divides it on its two main halves: the old town of San Félix in the east, and the new town of Puerto Ordaz () in the west. The city was officially founded in 1961 by the unification of this two former settlements, but the history of San Félix goes back to its foundation in 1724. Within the city limits are located the site of Cachamay Falls and Llovizna Falls.Dydyński, Krzysztof, & Beech, Charlotte (2004). ''Venezuela'', p. 293. Lonely Planet.

Apure River
The Apure River is a river of southwestern Venezuela, formed by the confluence of the Sarare and Uribante near Guasdualito, in Venezuela, at , and flowing across the Llanos into the Orinoco. It provides significant transportation in the area. Origin Most of the streams that ultimately form the Apure originate in the Venezuelan highlands of the Cordillera de Mérida and only some minor affluents of the Sarare River come from the Cordillera Oriental in the Colombian Andes, entering Venezuela at the confluence with the Oirá River which has a very narrow and steep valley and forms the border between the two countries for . The Oirá River starts in Venezuela and its thalweg forms that border for several kilometres downstream. The Uribante River is longer than the Sarare and flows from the Táchira-Mérida border, near the town of Pregonero. The Apure's drainage area thus includes the slopes of both the Colombian (less than 0.5 percent of its total area) and the Venezuelan And ...

Meta River
The Meta River is a major left tributary of the Orinoco River in eastern Colombia and southern Venezuela, South America. The Meta originates in the Eastern Ranges of the Andes and flows through the Meta Department, Colombia as the confluence of the Humea, Guatiquía and Guayuriba rivers. It flows east-northeastward across the Llanos Orientales ("Eastern Plains") of Colombia following the direction of the Meta Fault. The Meta forms the northern boundary of Vichada Department, first with Casanare Department, then with Arauca Department, and finally with Venezuela, down to Puerto Carreño where it flows into the Orinoco. The Meta River is long and its drainage basin is . The Meta divides the Colombian Llanos in two different parts: the western portion on the left bank is more humid, receives the relatively nutrient-rich sediments from the Andean mountain range and therefore soils and tributaries are also nutrient-rich, while the eastern portion, ''high plain'' or ''altillanu ...

Guaviare River
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 1760 km) and water flow. Thus, the Guaviare is hydrologically the main stream of the Orinoco system. The Guaviare has its source in two other rivers, the Ariari and the Guayabero, which in turn have their own sources in the eastern part of the Andes. At long, it is the longest tributary of the Orinoco and is navigable for of its total length. The Guaviare is considered the border between the Llanos and the Amazon Rainforest The Amazon rainforest, Amazon jungle or ; es, Selva amazónica, , or usually ; french: Forêt amazonienne; nl, Amazoneregenwoud.

Caroní River
The Caroní River is the second most important river of Venezuela, the second in flow, and one of the longest, from the Kukenan tepui through to its confluence with the Orinoco River.

The confluence takes place in Bolivar State. Hydraulic regime The Caroní is one of the rivers with the highest discharge rates in the world, with respect to the area of its basin. The average discharge is , with variations caused by the wet/dry seasons. The average maximum discharge is , and the average minimum is . Among the historic extremes are . The Caroní supplies 15.5 percent of the discharge of the Orinoco river. One of the characteristics of the Caroní's water is the dark color, caused by the high amount of humic acids due to the incomplete decomposition of the phenol content of the vegetation.
