Guaviare River
Template:Short description Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters".
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 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 Template:Cvt long, it is the longest tributary of the Orinoco and is navigable for Template:Cvt of its total length. The Guaviare is considered the border between the Llanos and the Amazon Rainforest. Its main tributary is the Inírida River.
