The Tambo River (Spanish: Río Tambo) is a Peruvianriver on the eastern slopes of the Andes. The name only refers to a relatively short section of the waterbody; about 159 km (99 mi) long. It starts at the confluence of the Ene and Perené Rivers at the town of Puerto Prado. From here the Tambo flows 70 km (43 mi) in an easterly direction and then turns north. When merging with the Urubamba River at the town of Atalaya, it becomes the Ucayali River.
Tambo River (Peru) in the context of Apurímac River
The Apurímac River (Quechua: Apurimaq mayuIPA:[ˈapʊˈɾɪmaχˈmajʊ]; Spanish: río Apurímac, IPA:[ˈri.oapuˈɾimak]; from Quechuaapu 'chief' and rimaq 'the one who speaks, oracle', thus 'the chief oracle') rises from glacial meltwater of the ridge of the Mismi, a 5,597-metre-high (18,363 ft) mountain in the Arequipa Province in the south-western mountain ranges of Peru, 10 km (6.2 mi) from the village Caylloma, and less than 160 km (99 mi) from the Pacific coast. It flows generally northwest past Cusco in narrow gorges with depths of up to 3,000 m (9,800 ft), almost twice as deep as the Grand Canyon, its course interrupted by falls and rapids. Of the six attempts to travel the full length of the Apurímac so far, only two have been successful.
After 730 kilometres (450 mi), the Apurímac joins the Mantaro River and becomes the Ene River, 440 m (1,440 ft) above sea level; then after joining the Perené River at 330 m (1,080 ft) above sea level, it becomes the Tambo River; when it joins the Urubamba at 280 m (920 ft) above sea level the river becomes the Ucayali, which is the main headstream of the Amazon. Sometimes the complete river from its source to its junction with the Ucayali, including the rivers Ene and Tambo, is called "Apurímac", with a total length of 1,070 km (660 mi).
Tambo River (Peru) in the context of Urubamba River
The Urubamba River or Vilcamayo River (possibly from QuechuaWillkamayu, for "sacred river") is a river in Peru. Upstream it is called Vilcanota River (possibly from AymaraWillkanuta, for "house of the sun"). Within the La Convención Province, the name changes to Urubamba. A partially navigable headwater of the Amazon River, the Urubamba rises in the Andes to the southeast of Cusco. It originates on the slopes of Cunurana in the Puno Region, Melgar Province, near the La Raya pass. It flows north-north-west for 724 km (450 mi) before coalescing with the Tambo River to form the Ucayali River.
The Urubamba is divided into the Upper Urubamba and the Lower Urubamba, the dividing feature being the Pongo de Mainique, an infamous whitewatercanyon, where the river narrows to a width of 45 metres (148 ft).
