Viliui

Viliui

 

a river in the Yakut ASSR and Krasnoiarsk Krai; the largest left tributary of the Lena River. The Viliui is 2,650 km long and has a basin of 454,000 sq km. It flows through the Central Siberian Plateau and in its lower course, through the Central Yakut Lowlands. In its upper reaches it cuts across a swampy lacustrine plain and further down, flows through areas of traprock. Here the valley is of a mountainous type with canyon-like narrowings (to 160 m) and is extremely winding. The slopes are precipitous and are covered by forests; the river has rapids at this point. From the urban-type settlement of Chernyshevskii to the mouth of the Chirkuo River, the Viliui is part of the reservoir of the Viliui Hydroelectric Power Plant (that began producing electricity in 1967). Below the village of Suntar the valley broadens. From the town of Viliuisk to the mouth, the Viliui flows through a broad valley with a floodplain terrace; here the river has a forked channel and islands. (Khochentakh Island is up to 15 km long.)

The chief tributaries are the Ulakhan-Vava, Chirkuo, Chona, Ulakhan-Botuobuia, and Ochchugui-Botuobuia on the right and the Akhtaranda, Markha, and Tiung on the left. The Viliui is fed predominantly by snow. The average annual discharge at Chernyshevskii (the Viliui Hydroelectric Power Plant) is about 600 cu m per sec; at Suntar it is about 800 cu m per sec; and at the mouth, about 1,700 cu m per sec. The maximum spring discharge in the middle course is 10,000-15,000 cu m per sec, and the minimal winter discharge is 2-5 cu m per sec. The rise in the level during the spring is up to 10-15 m. The period of stable ice begins in the middle of October, and the ice breaks up in the middle of May. In the spring there are ice jams in the lower course.

The Viliui is navigable from the mouth upstream for a distance of 1,170 km, and when water is released from the reservoir, it is navigable as far as the settlement of Chernyshevskii. The main ports are Viliuisk, Niurba, and Chernyshevskii. The Viliui abounds in fish (sturgeon, taimen, Braehymystax lenok, Stenodus leucichthys, nelma, and others). In the basin of the Viliui there are deposits of diamonds (Mirnyi, Aikhal, and others), coal, natural gas, and common salt.

Initially identified in a small Yakut-Evenk population on the Viliui River of eastern Siberia, the disease subsequently spread through human contacts to new geographic areas, thus characterizing Viliuisk encephalomyelitis as an emerging infectious disease.
Strong evidence exists that VE is disseminating through migration of affected persons from villages along the Viliui River in Eastern Siberia, where VE has been endemic for at least a century, to densely populated regions around the city of Yakutsk (6), located [approximately equal to] 4[degrees] (450 km) below the Arctic Circle (7,8).
We conducted a detailed study of 5 families living in villages along the Viliui River and of 1 family in the region surrounding the city of Yakutsk, to which the disease has recently spread (Figure).

Community-based research in post-Soviet Viliui Sakha indigenous communities of northeastern Siberia, Russia, has shown that inhabitants define sustainability as the building of local diversified economies, communities, and health via strong local leadership, a shared vision to work toward common goals, the reinstatement of local knowledge, and rights to land and resources.
Des recherches communautaires realisees au sein des collectivites indigenes post-sovietiques de Viliui Sakha dans le nord-est de la Siberie, en Russie, ont permis de constater que les habitants definissent la durabilite comme l'edification d'economies et de collectivites locales diversifiees et en sante grace a un bon leadership local, a une vision partagee visant des objectifs communs, au retablissement du savoir local et aux droits a la terre et aux ressources.
