Aus Wikipedia. Nicht dargestellt. Auszug: The Orinoco is one of the longest rivers in South America at 2,140 km, (1,330 miles). Its drainage basin, sometimes called the Orinoquia, covers 880,000 km, 76.3% in Venezuela with the rest in Colombia. The Orinoco and its tributaries are the major transportation system for eastern and interior Venezuela and the llanos of Colombia. Map of Lower Orinoco 1897Although the mouth of the Orinoco in 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, on the Venezuelan-Brazilian border, at 1,047 m of elevation ( ), was only explored in 1951, 453 years later, by a joint Venezuelan-French team. The 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, and Antonio de Berrio sailed down the Casanare, to the Meta, and then down the Orinoco and back to Coro. Alexander von Humboldt explored the basin in 1800, reporting on the pink river dolphins, and publishing extensively on the flora and fauna. The course of the Orinoco forms a wide ellipsoidal arc, surrounding the Guiana Shield; it is divided in four stretches of unequal length that roughly correspond to the longitudinal zonation of a typical large river: Panorama of the Orinoco River. Orinoco River, the second largest in South America, at its confluence with the Caroni River (lower left)At its mouth, the Orinoco forms a wide delta that branches off into hundreds of rivers and waterways that flow through 41,000 km of swampy forests. In the rainy season the Orinoco can swell to a breadth of 22 kilometres and a depth of 100 meters. Most of the important Venezuelan rivers are tributaries of the Orinoco, th...http: //booksllc.net/?l=de
