Caroní River (Venezuela) : ウィキペディア英語版 | Caroní River
The Caroni River is the second most important river of Venezuela, the second in flow, and one of the longest, from the Tepui Kuquenan, where it originates with the same name Kuquenan, up to its confluence with the River Orinoco to which it belongs. The name "Caroni" is applied starting from the confluence of the Kuquenan with the Yuruani, at from the source of the Kuquenan and from its discharge in the Orinoco. The meeting takes place in the south of Venezuela, in Bolivar State, being the most important tributary of the Orinoco, mostly because of the high discharge rate. The higher basin of the Caroni is situated in the Gran Sabana (Canaima National Park) close to the border with Brazil. ==Hydraulic regime==
The Caroni 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 Caroni supplies 15.5 percent of the discharge of the Orinoco river. One of the characteristics of Caroni'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. The Caroni therefore belongs to the blackwater rivers, as does the Negro River, or Rio Negro in Brazil, Venezuela and Colombia. In the late 1940s diamonds were found in the Caroni basin near the famous ''Lost World Region'' which then was accessible only by aircraft and four wheel drive vehicles.〔("Treasure Hunt In A Lost World." ) ''Popular Mechanics'', September 1950, pp. 73-79.〕
