The Tschikoi (Russian Чикой, Mongolian Цѳх гол / Tsöch gol ) is a 769 km long right tributary of the Selenga River in the Russian Trans-Baikal and along the border with Mongolia. The Tschikoi is the most water by far tributary of the Selenga.
Course
The Tschikoi rises approximately 1800 m on the southeast edge of the Chi cocoon Mountains. This south-eastern foothills of the mountains Daurian bears in this area alpine character with altitudes above 2,500 meters; above the source of the Tschikoi the Tschikoiski Golez rises ( 2334 m). First, the Tschikoi flows in a northeasterly direction. Its valley forms the border between the Daurian and the southeastern portion of the West Borschtschowotschnygebirges. Then the river turns to the north, cuts through the still 1600-2000 meter high main ridge of the Daurian Mountains as well as the same high Tscherskigebirge (not to be confused with the Tscherskigebirge in northeastern Siberia ).
Further north, the river turns sharply to the west to southwest direction. It flows here on the territory of the Trans-Baikal region, reached later, the Autonomous Republic of Buryatia and the border between Russia and Mongolia ( Selenge aimag ), which he followed more than 100 kilometers. About 30 kilometers west of Kjachta the Tschikoi turns again to the north and finally joins up with Nowoselenginsk, about 25 kilometers southwest of Gussinoosjorsk at 535 m altitude in the Selenga River, the largest tributary of Lake Baikal.
Especially in the lower reaches of the river forms meanders and many arms. The most important tributary is the 337 km long refectory (Russian Менза, Mongolian Минж гол / Mindsch gol ), next draw cocoon, Aza, Katanza (Ar - Chadants gol ) and Chuderiin gol (also Chudriin gol, all from the left).
Hydrographic
The catchment area of 46,200 km ² comprises Tschikoi. In estuaries near the river reaches a width up to 200 meters and three meters deep; The flow rate is 1.3 m / s
The Tschikoi freezes from late October / November to April / early May. He can partially freeze through the upper reaches to the bottom.
The average discharge is at Poworot, about 20 kilometers above the mouth of 274 m³ / s, with a minimum monthly mean of 17.7 m³ / s in March and a maximum monthly average of 712 m³ / s in August. Throughout the summer and autumn months of Tschikoi leads floods.
Infrastructure
The Tschikoi is in the lower reaches, approximately from the Mongolian border, navigable.
On the middle and lower reaches there are many smaller towns, but right on the river no cities. Near the mouth of the A165 trunk road from Ulan -Ude goes according Kjachta and the Mongolian border. Among the places on the middle reaches of the river to Krasny Tschikoi and the spa Jamarowka lead two, the north of the river located mid-mountain ridge ( Malchangebirge ) about crossing roads: the regional road R425 from Petrowsk - Zabaikalsky and another unpaved after Khilok.
